The problem with the trophy 4.6 is the pullstarts. They are complete garbage, and for some reason the truck has some issues with rotostart. The plate doesn't want to fit mine right, and the gear inside keeps getting jammed.
They are SUPER tough though, recently mine hit 2 trees at full speed in a row, drove up them 6-7 feet, did a back flip and landed right on the side. Amazingly no damage other than a shattered piston connecting rod (Ouch!) This was my fault though. Make sure you get a throttle return safety spring and make sure its on right!
And make SURE to tighten all bolts before you drive it. I lost a wheel and 2 motor mount bolts from them being loose. And when I removed my head it wasn't tight either.
