take your time, I dont think anyone picked up fixed pitch heli like Falcon 40 that easily. They are all very twitchy and squirrely to begin with, even with folks coming from Co-axial. I almost gave up, but then realized my setup was making it worse.

Regarding flybar weights, I moved it midway to begin with and now have them completely removed. Basically if you find less control on heli, move them in. Putting them all way outside makes the heli respond very slowly to inputs, and that was an issue for me.

The seesaw bracket is the one through which the flybar passes near the shaft. The blue lines in photograph should be eyeballed and leveled. So both paddles should be parallel and in line with the seesaw bracket in the center.
