Can you actually get a serious(ish) rc car for £50 or so?
I don’t think getting a serious RC car for a 6 year old is a good idea.
A serious RC car will just end up getting crashed or cause an injury. This is what I bought to get my 4 / 9 / 10 year old into RC in a much more controlled way.
Proper pistol grip controller with a dial to reduce the top speed:
It’s so small that you can’t do any damage to the car / yourself:
It has a lipo so runs for about 40 minutes and charges on a USB-C. It comes with 1 pre-painted shell and 2 un-painted ones if you want to get into painting shells:
It’s so simple there’s not much to go wrong. The most annoying thing is having to take it apart to clean out the fluff trapped on a regular basis and it is properly fiddly:
There’s a race track on a mat that you can buy. That’s me racing with my son:
The 2 cars and the mat comes to about £100 on Banggood, so your 6 year old can use the £50 to buy his car and you can buy yours + the track. I ordered on Monday and received on the Saturday which isn’t bad at all.
I do let my 10 year old loose on my bigger stuff occasionally but under very close watch.
