I made a bunch of changes, little ones, that add up to a new version. The ones I can remember? Added weight all around, now you can really see the sink rate. Dialed in some motor offset to relieve the torque roll and to fly more level. Went to a 2-bladed prop and you can't even tell when it's spinning. Played with the CG a little. I think it flies way more scale now and you almost HAVE to use rudder in the turns...you can see the tail not keeping up. What a hoot!
