I've been experimenting on a similar little e-foamie myself. It's the firebat from Tower. Mine also makes prop noise when stalled. Since I'm working on post-stall flying with it, the conversion of thrust into noise is annoying



I've made all sorts of little mods from making gap seals with scotch tape to adding balsa yaw vanes to the nose. My next addidtion will be leading edge droop/notches to try to remove wing-rock.

It's a neat little flyer. Funny, Tower sells them overweight and under-powered. If they'd just used a different (not more $$, just different) selection of parts, it wouldn't have the horrible reputation that it does.

I have a thread that's served as sort of a log of my development with this little plane. You might check it out for some inspiration:
