was wondering if someone can tell me the diff between an engine you use on a plane vers. a car engine. can they be modified to run on both or are they strickly just for cars or for airplanes. the only diff i seen so far is the mounting plates,(can be made) exhaust witch can be matched, i mean people do costomize there full size cars, just want to know if it is possible and i am curious, And new to RC

also are the engines hard to REbuild if need be?
