RE: AP hornet .09
Well i don't have an AP .09 but i do have a TT.07, it does run good and throttles very well, it is a little heavy and doesn't put out huge power #'s, i'm getting 17000rpm on an APC 6x3 but i bought a Herr lil extra awile back and desperatly waited for the Norvel .074 to come back in stock, that never happened so i ended up putting a magnum .15 on it and i wasn't disappointed, at $59.99 this is a great engine that is both light and powerful.
I thought the AP .09 and AP .15 are the same physical size, what is the weight of the AP .09? if it's up there you might want to consider a Magnum .15 and just upscale the plane a bit.
