Well I am sure gas can be flown with standard servos and receivers, but the fact remains vibration is an issue with gas. Most guys with gas engines I know carry extra switches becasue of the failure rate due to the vibration. Ignition issues with a gas engine can drive you nuts, when everthing is right they are great. Most of the gas pilots I know will inspect for loose bolts etc after a few flights until everthing gets tightened, glued, lock-tited, until it stays put. Not to say glow doesn't require good maintence also, but vibration will kill a gas plane if maitenance and checking things out is not done often and thoroughly. MHO
