How many gallons do you expect these engine to last?
Do heli engines last much longer than the high performance car engines?
Looing at a raptor 90 with 4 gallons though it? will i have to replce the engine soon?
Thanks

With 4 gallons thru the engine. It is just starting to be broken in. Engines will last many 100's of gallons with proper tuning and routine maintnance. That would be changing the bearings ocassionaly when needed.

Well the buggy engines are turning 25-40 K Rpm's and they are ingesting a lot of debris at times even with good filter systems.
Heli engines are turning about 16K max. But if you don't tune the engine correctly. It really doesn't matter what the RPM operating range is. LOL Neither one will last long.
