I used modeling clay :D but I have ordered some stuff designed for RC wheels already.
Yes I can't explain why my fan was always on, because ESC was cold, maybe it's a safety protocol when the BEC is under 6S or ? Anyway, the temp is great, last time it was 120F but I realised that it was under hard sun and 85F outside, so mission accomplished :D
Lets get the 60 mph ^^
