well to make a long story short....i received a neo 3.0 ready set and out of the box the motor would not crank at all. After unsuccessfully trying to contact kyosho customer service with no success I took it upon my self to diagnose the engine. First there was no shim Behind the flywheel, there was no chrome on the top of the cylinder, and the cylinder is egg shaped leading to the engine never gonna be able to run right out of the box. Also the receiver in the car is non functional so the car was doomed from the very start. Is there an engine I can swap this out with without having to do heavy modifications?. Any help would be apperciated.
