nitro is really not that expensive at a club level ,u must be thinking of the guys who spend 1000 to 2000 and a lot of them cant drive. it all depends on how u setup your cluch to make it last long the first thing is clean and sand them after a day of racing and have softer springs on the shoes not to soft and they will last and as for glow plugs i havnt had many at all blow on me reguarless if it was rich etc. my point is nitro doesnt have to be expensive
and the fuel residue get some hand cleaner or a rag no big deal. im not that good at electric i just like the little lag the nitro engine has
