First floaty plane, input on characterstic needed
Well,
I finally got to fly my H-9 electric cub on floats. The weather was rainy and got windy, but I managed to get in the maiden float flight on Sunday (my very first float flight!). It was pretty uneventful and I got it back down without dunking it!
It was doing something rather strange in flight, if anyone has some input. When the power was reduced, the plane tried to dive, not a little nose down, but a hard vertical dive. It would also exhibit this tendancy with the slightest touch of down elevator. The plane, with floats, balances right at the aft end of the CG range, and did require some up trim for level flight. Everything else seem normal.
Without floats, it flew fine and did not exhibit this tendancy (even when the cg was shifted an inch behind the range). I have not checked the incidence since it was pre-set by the arf compoonents, but the "veterans" that eyeballed it this weekend said it looked good.
