... Congrats on the maiden Herb, what point of CG did you end up with? I had some down trim aswell on the maiden ...
Thanks guys. I put the CG at 66mm or so (what Aeronaut recommends), perhaps 1 or 2mm ahead of that - I'm not that good with setting the CG to within two mm's
Mine was initially quite sensitive on the elevator, so I reduced the rate a bit further after the first flight. Without the wing sweepback it takes very little elevator movement to get the Panther to pitch up/down. My big 16-cell GP 3300 packs is also seated quite close to the CG, so the moment of intertia about the pitch axis is small.
I use dual rates on the elevator, because with the recommended full throws on the elevator it seems to slow down nicely on landing. Not enough elevator, and you have really looong landing approaches
