Hey guys....I just developed a problem I've not seen before with my HBv.3 Had a nasty crash causing me to rebuild the rotor head....new shaft...new head...new grip...and new blades.......
THe problem is: after liftoff the bird slowlystarts going into a nose dipping oscillation that only gets worse if I continue to fly. The main shaft is true....and there is no appreciable vibration.
I'm clueless and could use any advice.
