BULL you cant help but have problems inverted T/S RC with transition
ORIGINAL: MerlinL14
an engine that is mounted inverted anywhere past 90 deg. WILL NOT run the same as an upright engine.hydraulic lock can be a problem but, usually the acceleration and idle suffer severly unless some sort of glow driver is used to assist the plug in keeping lit. occasionally a very well broken -in engine (two stroke ) will run ok inverted but its rare.
Anyone want to buy a hanger full of RARE engines!!!!!! All mine run inverted, 2 and 4 stroke, and I suffer not 1 iota of any of the "problems" you describe.
