On the subject of Seat tube angles older TCR’s were suplied with seat posts with a clamp with a lot of set back. The posts on more recent TCR’s I am pretty sure are straighter. My 10 yr old m/l bike with a 90mm stem has approx 30mm set back on the seat post and is set with the saddle in a rearward position. not sure about 2017 posts v current.

I also have an older TCR. (as in probably 10 years old.) I am also 5’10. My TCR is an m/l. I shortened the stem from the standard 100mm to 90mm following a bike fit. However that bike fit also moved the saddle a long way back on the rails. I have often wondered whether a medium would have been a better choice. The bike feels a bit long when sat down but then if I want to get out the saddle it feels too short.

Basically I think at 5’10 you can get either m or m/l to work. I initially thought my m/l was much too big, but that was partly a flexibility thing which got better with a bit of riding. A pro at 5’10 would probably be on a small with a much longer stem to get low down, but ith a lot more flexibility than I have.

It’s not an older car. It’s the latest model and only bought it about 3 weeks ago after being retired for a number of years.

Ben C trims material from the top deck and mounts the pinion as far out on the shaft as is physically possible. It is not a good solution.

Ben runs a ratio of 2.8 indoors on carpet so I don’t think it’s just the big tracks that are an issue.

At 3.6 I have certain cars running into me at the end of the straight at Hinckley indoors.

For clarity I haven’t modified the motor. I’ve modified the gear and made an adapter to fit it. Essentially a DIY long boss pinion. Legality won’t be an issue,

One of the things I’m not sure about is just how high I might need to go with the ratio. The limit might be about 2.7 due to the servo mount.

Applied to the xray forum several weeks ago but my request hasn’t been accepted yet.

so I have made an extension for the motor shaft.

The extension is 5mm diameter so pinions then have to be drilled out to fit. The first attempt wobbles a bit as the drill appears to have gone off course when it hit the grub screw hole.

@dlr what other cars are you aware of which have problems getting the ratios needed?

Also realised that that the motor shaft is effectively 3mm shorter when compared with an old speed passion motor I have. The shaft length appears the same but What they have done is added extra material to the motor can to create vents which has the effect of moving the rotor across by 3mm.

@Mert, Quite a few racing cars need long boss pinions, e.g. things like a Schumacher L1R 4wd and some 12th scale circuit car. However most use standard short boss pinions.

@dlr

The car I have bought is an xray x4f.

The car is designed to accommodate a maximum pinion size of 35T.

As standard with a short boss pinion it needs to be mounted towards the end of the shaft, and a long boss pinion would be better.

For pinions which are bigger than 35t they need to be positioned further out to avoid hitting the top deck.

Basically what’s happened is some people in Europe (EtS) set some rules for a racing class which included a control esc and 17.5t motor with a 17.5k rev limit and maximum gear ratios that could be used. (4.5 outdoors and 5.0 indoors) The manufacturer XRAY has designed the car to comply with those rules which would mean a maximum pinion size of roughly 27 or 28 tooth.

The British people (BRCA) who set the rules for racing in the UK decided that they didn’t want to follow european rules.

The BRCA rules use the same control motor and speed control as the Europeans but the rev limit has been reduced to 15K and there are no restrictions on gear ratio.

The result is that to get optimum performance the car needs to be geared much higher than the designer envisaged with pinion sizes of at least 40T needed on some tracks.

Speaking about rw racing, I recently purchased some spur gears and a 35T pinion from RW racing. The Spur gears are great but the new ( short boss) pinion has a noticeable wobble (even when moved inboard on the motor shaft.) I have a lot of older rw pinions which are great but they were all purchased a very long time ago.

Thanks for the reply RJ. Not sure I agree about the force thing though. It sounds backwards to me.

in any event this is for a fwd touring car running 17.5t fixed timing so loads are not high.

The alternative which the team drivers use involves a short boss pinion mounted right on the end of a motor shaft and taking a dremel to the top deck of the car in an area where there isn’t much material to lose and is designed to flex.It’s not clever.

Wasn’t expecting to get anything from rc suppliers, was thinking more gear manufacturers but they don’t use the same terminology in there catalogues so not sure exactly what I should be searching for.

diy option b involves machining a boss on the lathe. Overboring to a short boss pinion to say 6mm and securing it to the new boss with retaining grade loctite.

Anybody know where I might find Long boss pinions in larger sizes? Looking for around 40T in 48dp. Can’t find anything larger than 31T from the usual rc suppliers.

My guess is that the system is in the 2.4ghz band. That band is essentially a small band of unregulated spectrum which can be used without a licence. The result is it gets used for an awful lot of different devices these days and interference is common. Older and cheaper devices tend to be more prone to this.

I have a 2006 bmw and used to work with radio masts. Parking near 2 4ghz dipoles on towers would stop the remote from working.

Also had issues with doorbells at my but with the doorbell being activated by aneighbours key fob.

Akashas are la sportivas ultra shoe. They do not have the same level of cushioning as speedgoats and the rocker effect is less pronounced. With la sportive you really need to try them on as sizes vary significantly between models. For akashas they size up small so you should expect to go up 1/2 a size.

Highway code isn’t statute it’s just a guide. Specifc bits are covered by some legislation eg speed limits.

I realise that. Failure to comply with the dogs bit could for example potentially be prosecuted as reckless conduct under Scots law? Other laws are available.

Isn’t the highway code similar to an Approved code of practice in health and safety law? I.e. an acop is not the law but it provides a benchmark for the standard that must be met to comply with the law so you do not have to have your dog on a lead as per rule 56 but if you do not, would need to prove that you had put measures in place which achieved the same thing.

The point is largely of academic interest as the highway code and rules for dogs are never enforced.

Does highway code rule 56 not infer a criminal offence if breached. I.e dogs must be on short leads when on a road or path used by cyclists.

Also, what owner would willingly give you their details or let you take a photo

Fortunately the law has thought of that and legally the dog has to have the contact details of its owner on its collar. Just grab the tag with the arm that fido does not have his teeth sunk in to.

I am ashamed to say my dog loves folding ebikes. If a family member leaves the house on foot or by car or a normal bike he is not particularly interested.

But If he knows one of our family has left the house on a folding ebike he forgets he is a sofa dwelling cavapoo and will attempt to follow the scent at speed and hunt the ebike down like some sort of demented fox hound. He will do this 30 minutes after the ebike has left, when everybody else has forgotten.

People are missing one of the most important features of the jetboil.

The logo on the insulating cover on my jetboil gradually changes colour as the water gets hotter.

I know that the water is boiled when the logo has completely turned orange.

Inferior products produced by competitors rely on the user to look for steam to determine when the water has boiled. They do not change colour at all.

@easily

Read the link that you have posted and you will see that whilst windows itself is going 64 bit only and will need a 64 bit processor it will retain compatibility with old 32 bit software.

That is not true of apples approach which deliberately removes compatability with old software. in apples case at the release of Catalina it broke a lot of commercially available programs which contained older code.

If you want futureproofing then the pc wins hand down.

APPLE deliberately remove older features in macos on a regular basis.

I bought an imac I think about 18 months ago. When I bought it macs could run 32 bit software.

AN OS update just 2 weeks later removed all support for 32bit software and it now only runs 64 bit apps.

Fine if you only run the latest apps. A big problem if you run older software which is never likely to be updated. – very common in my industry.

I was also annoyed find that apple had deliberately removed the feature that let you use imacs as a monitor for a pc or games console.

Aren’t fairy houses normally small wooden doors stuck on a tree?

Select BMW and it says that all petrol BMW’s can be run on E10 regardless of year of manufacturer.

Bearing in mind that BMW have been round since 1917. I am sceptical that they have checked all of them.

Without anything to tell you which models have been checked ot how far back they have gone, this is meaningless.

Check the title deeds and Covenants for your house to see if they ban flags.

guide to flying flags

The above might be worth a read:

All flag flying is subject to some standard conditions
All flags must be:
• be maintained in a condition that does not impair the overall visual appearance of
the site ;
• be kept in a safe condition;

So if the flag gets dirty, is a bit tatty, or you can persuade the authorities it is an eyesore, or if it is not safe then it is not allowed, regardless of whether it needs planning consent.

If I had time on my hands I might make enquiries as to the model of flag pole (there’s probably a label on it) and enquire with the manufacturer about what windspeeds it is suitable for. – (Just tell them you want a flagpole in your garden but are concerned the flagpole might break in the wind.)

A flagpole might be deemed as unsafe if it is fitted in a location with a wind speed that it is not substantial enough for. (A very common issue and possibly why a certain Scottish castle lost a flagpole in recent years!)

A lot of flagpoles are not designed for exposed locations such as the sides of valleys. And wind speeds are higher in say Northern England than London.
The manufacturer should also be able to advise as to when a flag needs to be lowered, and the maximum flag size.

If a manufacturer says that a flag must be lowered in high wind, and the owner does not do this then that might also be viewed as unsafe, because it can snap a flagpole. – The same applies if the flag is too big.

Or you could just point out to the authorities that it sways a lot in the wind an you are concerned about safety, and let them investigate.

A mobile phone video of a flag pole that bends a lot in the wind might provide useful evidence.

Emphasise if it is close to the boundary and with potential to fall on the road or your own house.

Waist packs like to bounce and chaife when running. It doesn’t make too much difference what the model is. It becomes a problem when there is too much weight in them.

The elasticated waist bands type are much better at resisting bounce than traditional bum bags and a good option for say just a phone. (I have one from a firm called naked)

The problem I have found with the bad type is the sizing and elasticity has to be perfect, or they end up either too tight or too loose. They also get tighter as you add gear.

For carrying anything more than a few 100g or as soon as you add fluids, a race vest is the best option for running IMO.

As a small child my brother decided to eat the mains powered fairy lights on the christmas tree.

The fairy lights (except for the bulbs he ate) kept working. He was not electrocuted, and was absolutely fine. The doctor at the hospital, said it is ok to eat glass as long as you chew it up properly.

Based on a study of n=1, eating fairy lights is a low risk activity.

Also based on a study of n=1. Putting your finger in the mouth of a child who is trying to eat fairy lights and has a mouth full of glass is dangerous, and result in injury to the finger.

Tried following MAF in the past.. – Didn”t work.

The thing that people miss about MAF is it isn’t really about the heart rate. it’s about controlling and minimising variables and tracking data so that you have a baseline, and can make adjustments accordingly.

The heart rate in the book is only supposed to be rough guidance and is supposed to be corrected for the individual.

Whilst MAF training pace is supposed to be slow, it is important to understand the context. – Slow is a relative term.

If you look at the detail of the book MAF was developed based on athletes running on a track.

MAF requires an aerobic pace. That means the pace is slow relative to the typical race or training pace of a college athlete who has probably been competing in 400m – 1500m events. People who tend to be quick but lack endurance.

If you are running at a steady pace on a track then there are no accelerations or sudden direction changes, and the surface is perfectly flat. It is relatively easy to keep a constant heart rate. So heart rate is a good reliable indicator of effort

If you are running in the real world there are constant changes in direction, undulating surfaces, gentle slopes etc. This causes effort to varyand your heart rate to increase. – It means that when you limit your pace to achieve the suggested MAF heart rates you will slow down a lot.

My point being that running at MAF heart rate on a track or perfectly flat surface is not what I would call slow at all. It’s quite a hard effort. – (just more of a hard marathon than sprint.) On a track the pace for me at maffetone heart rate was almost identical to that recommended by most other training systems.

But when not on a track, I found myself going very, very, slow when trying to train in accordance with MAF heart rate. – I would end up significantly changing my stride or walking. It wasn’t due to a major lack of fitness. It’s a problem with the way MAF and heart rate monitors work.

Another problem with MAF is that there are alot of variables that affect heart rate other than how hard you are running, e.g. variations in temperature, if you are scared or excited for any reason, when you last ate, caffeine, undulating terrain, etc etc. All less of an issue in a consistent training routine on a track in sunny Florida.

And heart rate monitors rely on a minimum effort to make you sweat. – A problem in a scottish winter, if running slowly. Even when they do work there is a lot of lag, between you slowing down, your heart rate dropping and the display updating.

Note that whilst their training pace may have been slow, Maffetones athletes raced relatively frequently. – That racing trained them to go fast.

I agree with most of Maffetones, training philosophy.But it only works if all of the variables can be strictly controlled.

If you have access to a running track, turbotrainer or treadmill,or are cycling on an obstruction free road, then I can see how Maffetone would work well.

But otherwise I would just aim for most of your running to be at a moderately easy pace.

*Finds standard bland Audi genericism -looks like an A5*

Somebody that I am ashamed to be related to has an Audi A5.

The car has just been wrapped in a silver glitter finish. It
is very sparkly.

Inside there are hundreds of Led’s covering the headlining. they change colour and produce a twinkling star effect which is controlled using an app.

Air suspension has been fitted so that the car can be lowered to the ground.

Previously the lenses on the fog lights were fitted with filters which meant that they projected red love hearts on the road but those have now been removed.

On the op’s diagram which provides
clarification there appears to he a substantial wall at 5 miles.

The maximum distance the back of the first car can go is 5 miles minus the length of the car after it hits a wall at 100mph.

The 2nd car just needs to keep moving at any speed and they will catch the first car within 5 miles.

so, aggressive sole, wide-ish toe box, 8mm drop. Any suggestions?

Merrel long sky or innov8 x talon ultra the merrels have quite a thick sole so more protective underfoot in rocky terrain and trails. Supposed to he 8mm drop but feels more to me.

X talon better for technical off piste stuff where ankle rolling is likely but less protective. 6mm drop from memory.

Also newer mudclaws feel much narrower than the older versions of the shoe due to the way the sole is moulded. Mudclaw 300’s if you can find them are a much more versatile shoe than the current mudclaws.

The spitting antelope is driving me nuts.
Waste paper basket

think about what the antelope is doing, not the antelope

for the basket what would you not want?

finally got the plum one. – another one where it is extremely picky on the wording.

don’t see any canoes

look on the mantelpiece there are what appear to two paper canoes with pebbles in front of them. – It feels like there should be an obvious phrase including the words rock and boat.

also possibly missing another clue o do with the knight who appears to be holding an unusual weapon which may be part pen?

7 to go

still missing the following: (some of which won’t be clues)

Any hints?

suspect that some of them I know the answer but not the exact syntax the quiz is looking for.

Think of a more traditional instrument

That’s misleading. The instrument is still a violin no matter what you call it.

The leopard is annoying me. Surely there is only one obvious leopard related phrase.

What’s the picture worth?

When young people need glasses it’s generally because of the shape of the eye. This affects the focal distance for both nearfield and distance vision equally and glasses can easily correct for this.

When you get old and need reading glasses its different. The reason is that the lenses of the eye loses flexibility* with age so the eye can’t adjust its focus for different distances. It loses the ability to adjust for nearfield vision first. The speed at which your eye refocuses can also be affected.

If the eyes own lens can’t adjust properly then different distances need different correction. Hence varifocals and bifocal exist.

New glasses may not help with your tree problem.

* I am not an ophthalmologist.

I think bont are the only ones I have seen who actually acknowledge the actual shape of a normal foot.

You can scratch them off the list too. Bont shoes have massive amounts of toe spring and force the toes into a permanently raised position to tighten the arch of the foot, which can be problematic.

I’m struggling with a chronic sesamoid injury at the moment and basically need shoes with a flat toe and zero drop heel. For cycling shoes I need to be able to pedal with my mid foot.

And trying to find steel toe capped safety boots with zero drop and no toe spring for work is proving impossible.

I too suffer from this. My big toes are much bigger than the rest, in fact if I amputated them I would take about 5 sizes less.

Thats why I’ve got a sesamoid injury. It was caused by squat thrusts on tarmac in shoes that didn’t have enough toe space, and pushed the big toe to one side.. – Bigger shoes would have put the ball of my foot in the arch of the shoe, so can’t win.

I have lost count of the number of times my nails have fallen off through rubbing on running shoes and every time they fall off they grow back thicker making shoe fit even more difficult.

OMM still do a system with a jacket and a half length sleeping bag which you attach to to the bottom.

Theres also another variant which doesn’t make sense to me at all, where, you get the same jacket, but with insulated trousers, and then you can clip a really short sleeping bag section over the feet.- Down slippers would be cheaper and probably lighter.

Both options seem far too expensive for what they are.

Personally I just take a down jacket or and then combine it with a very lightweight sleeping bag.

As lunge says, there’s no need to get a pricy Garmin model, any Ant+ strap will do. Here’s one for 21GBP, you can probably get them even cheaper (caveat emptor: the reviews are fine, but I’ve never used this particular model):

I would avoid buying from Coospoo on Amazon. The seller actively contacts purchasers and bribes them to remove bad reviews. I have reported them to Amazon for this previously.

I bought an optical arm based heart rate monitor from them last year. It was absolutely useless and did not give remotely consistant readings. I sent it back for a refund and left a 1 star review explaining my experience and the problems. A week after the refund They then sent me a message saying that they would send me another heart rate monitor for free if I updated my review.

They sent me a free heart rate monitor. It was a chest strap and a totally different type to the optical arm band one ordered.

I updated my review by adding additional lines saying they had got in touch and sent me a free heart monitor of a different type which appeared to work. I added a star but left all of my original comments.

They got very annoyed and sent several ranting messages asking me to delete my review and being quite impolite.

Shoes or cleats?

I had something similar where a bike fitter added plastic wedges to the forefoot of my shoes. They didn’t fit properly and flexed under load creating a clicking sound every pedal revolution.

Does it still do it if you put the bike in a stand and you turn the cranks by hand?

That would rule out headset for example.

(You might have more response in that Tamiya thread as that seems to be the general STW RC thread)

in the 90’s anybody who owned a Schumacher or an HPI would find it mildly insulting to be associated with Tamiya!

Which version of the club 10 is it?

The cougar was the buggy, but they also did a truck version called the storm. Later versions came with a fully geared transmission, but the early ones came with a fine pitch belt drive transmission. The belt drive transmission was very temperamental and would often destroy itself. The belt tension needed to be absolutely perfect. The rear of the chassis would often bend and throw the belt out of alignment. The diff balls were also really soft which caused problems with slipping.

Basically if you have club 10 with a belt drive transmission it needs to be run with a very low powered motor or you will kill it.Especially if you have not upgraded it to add a slipper clutch as most people did.

Battery’s will need to be replaced. Be aware that if your old charger was designed for nicads then it will overcharge nimh cells and may cause them to go bang. – You may need a new charger.

The nitro will probably need the engine stripping and a good clean to remove internal deposits if it has been sat for years. The glow plug will probably need to be replaced. Same with filters for the fuel and air. If it is a foam air filter and clean then they use a sort of sticky oil which will have dried up.. You will need to figure out what glow plug to use as they have different temperature ratings depending on fuel and engine, etc.
