I'm new to fuel-cars rc racing, and I bought myself a Tamiya TGS (expert
build-series) 1:10 glow engine car on friday.
On Saturday I did a break-in session, I drove 4 tanks with half-speed, rich
fuel, and rich fuel setting.
Today I wanted to do a next break-in session, but I couldn't move the
pullstarter at all !! I was scared my motor was damaged, but after sometime
I could pull the string again. Does anybody know what could cause this
