So I was out flying today when I decided I needed to work on some inverted hovering. I haven't really done much (any) inverted work but I decided today was good because there was very little wind and I was feeling gutsy.
I turned her over (nose in) and kept a decent hover for about 30 seconds, when my engine cut out. I managed to auto her in without any damage (first forced and first "inverted" auto...)
I didn't really notice anything but a buddy of mine said that when I was inverted that he couldn't see any smoke coming out of the exhaust, and the engine was pretty toasty when I got her back on the ground too! When she's upright the engine doesn't get excessively hot at all. But apparently when I'm inverted it goes lean...is this normal?
The heli is a Raptor 50v2 with an OS 46 FX-H engine...running 30% Power Master fuel, with a OS #8 glow...
Any help on getting this problem taken care of (or maybe at least how to avoid it...that doesn't involve not going inverted) will be appreciated!
