3der climbs on inverted?
 

Ok, I finally broke down and made a foamy. I had a lot of help at the SE IMAC regionals because of the bad wether. We looked over a few designs and free handed one. It is made of the dow blue foam stuff. I haven't had a chance to fly it in non windy conditions but it seems to climb a bunch inverted. In normal flight it flies fine but it still falls a bit foward when in a hover. Is this a problem with the aileron adjustment? Like both of them being too up or too down? Any thoughts would be great as this is my first time. It takes a bunch of elevator to harrier also and the wings rock a little.

Thanks in advance,

I have heard of several ways to fix this issue. My new, and first electric 3D plane, Efilte Ultimate climbed inverted. I added just a bit of flaps and it corrected it. I had read that worked for someone in an RC mag a while back so I tried it. Quick, easy and free.

The other thing several folks with my plane have done is mount the battery higher up, course mine is biplane. My battery is mounted as high as possible. So the flaps was my next attempt.

kewl. thanks for the info. I'll give both of those ideas a try.

Is your elevator trim centered with the stab and wing at 0 deg? I am guessing that you have a little down elevator? or your stab and wing are slightly off (wing pos or stab neg)

if you have a bit of down trim, and its good right side up, then climbs inverted... thats the CG. Its aft. When I fly far aft, I set the trims at zero, and just plan on a climb right side up and inverted.

if the wing is a little off of zero, then youcan adjust both ailerons up or down slightly... but then you have camber, and it'll fly different inverted anyhow...
