I started with a kyosho us sports truggy about 3 yrs ago. my wife bought it for me for Christmas. It was my 1st gas RC. I had had electric cars for 20 years. All I can say is I replaced damm near everything on that truck and it was alywas broken. Parts support in my area is non existent. The truck ran great. But just to change the wheels and tires I hadto change the hubs because it came with 13 mm hubs and all the truggy wheels are 17mm. It's still sitting in my garage with a new body on it. All it needs is an engine and ring and pinion. I run losi now and nowhere near the issues.
