Got a pair of No tubes rims with yellow tape fitted + black rim tape. Have followed instructions accurately (I think) but am failing miserably to get the tyre (Panaracer Trailraker, non tubeless) bead to sit and hold air, without adding liquid. When I pump the air flies out bu the the valve, even with tweaking the tyre.
Any thoughts or do I have to buy tubeless tyres

use a CO2 inflator or a compressor - it's sometimes the only way to get enough 'flow' to push the tyre bead into the rim strip quickly and generate a reasonable seal. Try taking the valve core out too if you can - the air will go in quicker.
Try inflating it with a tube,to seat at least one side on the rim,then take the tube out,add valve and sealant and pump.Or this video from Stan

Give some thought as to what will happen when your out on the trail. It its this hard now it can only get worse. I would suggest buying the right tyres for the job.
What kind of pump are you using? Just changed tyres on mine but I'm using a floor pump.
Trimix - if it happens out on the trails it'll be after the initial seal's been made and you can then either reinflate the tyre and hope the remainign sealant in there seals the hole or fit a tube.
Panaracers are very loose beads and not recommended by stan.
The problem is you're using a non Tubeless Panaracer tyre. They're notoriously the loosest tyres on the market...
Get yourself a tubeless version, or a non-tubeless Maxxis tyre for the best results. I'm a Bontrager "tubeless ready" tyre fan myself, as they're about as light as normal tyres but the beads are a bit tighter so they inflate easier when run tubeless (with sealant of course).
you could try heating the tyre with a hairdryer, having kept the tyre indoors - should make the rubber a bit more pliable. I've doen this afew times with Maxxis and it seems to work! (never tried a Panaracer though)
Panaracer = nightmare with Stans.
By "black rim tape" do you mean the rubber rimstrip? If not, go and buy said rimstrip. They really help with fitting loose tyres. If you already have one installed, wrap a few layers (go round the rim 6-8 times) of insulation tape over the yellow tape, then install the rimstrip over the top of this. This helps to make the rim "bigger", thus compensating for loose tyres. A compressor is pretty much essential IME with loose tyres. A decent track pump will do most Maxxis and Schwalbe tyres. Schwalbe are the easiest I've tried (and I've been using Stans for about 7 years now).
A final tip - remove the valve core, inflate tyre, then remove the pump and quickly thread in the valve core before the tyre deflates again.
You must use the spooge (liquid latex) with non-tubeless tyres - I use 100ml per tyre for longer life between top-ups and reliability when racing.

put tubes in and inflate to about 50psi. leave them overnight.
Then try inflating with neat fairy liquid all the way round the tyre where the sidewall/bead meets the rim. This will slow down the escaping air just enough to allow you to inflate the tyre.
Also, use a compressor, and make sure the valve core is removed the first time you inflate.
