I have a os FL 70, not the surpass 70!!! The engine is mounted upside down and holds and idle horribly but idles wonderfully with the glowplug is on. I have long lost the stock air-bleed setting from messing around with it. I emailed OS and the guy said that becuase the engine is upside down, fuel puddles at the glow plug, killing the engine. He said I would benefite from an onboard glow starter which makes sence to me. I was just wondering were i could get one of these. I was also thinking though, wouldn't the glow starter stay on all the time, thus burning up your reciever battery really fast. A friend told me that a onboard glow starter could be set so the glowplug turns on at idle but shots of at higher throttle settings. Is this true, becuase man that would work out great. Any advice please?
