I had my Maiden flight yesterday. I thought “my” plane would be magically immune to the “positive wing incidence issue”. Wrong! She lifted off and climbed faster than expected. I managed to push the nose down before it stalled and get things under control. Full down trim on my controller and the rest of the 12 minute flight was uneventful. The landing went fine. I’ll post a video of the last bit of my flight and the landing later tonight on RC Univ.
My plane is balanced at 5.5 inches as stated in the manual. I have not measured the incidence of either wing yet but I will now. I’ll do what I can to adjust the lower wing to 0 if this is required, as I suspect it is. As far as I can see, the only way to do this is to shave a little off each side of the fuse where the top of the lower wing meets so the back of the wing can sit deeper in the fuse to lower the angle. Has anyone done this? Any tips?? If the wing top is out, a few washers should do the trick. No problem there. I may also play with the C.G and bring it a little forward.
The Saito 170 seems O.K. power wise etc. I am running it fairly rich as it is new. I will try a 16 X 6 prop to compare it to my current 16 X 8. The other plane I am flying right now is a twist 150 with a Saito 180 in it. Definitely different birds. I’ll post again after I make the changes.
