I have fixed the sudden jump up problem when the 22E gets light, the collers from the flybar link was not tighten properly. It was tight enough for the flybar not to move from side to side but the paddles can move to change pitch, that's no good, she takes off smoothly after retightening the grub screws.

One thing we discover is that the W#22E flys good using 2S lipo packs, not a lot of power, we test it with the Walkera (?) 10C 2S 1300mah lipo pack and can hover for 12 minutes at eye level. The setup is: zero pitch @ 0~40% throttle, +5 @ 75% and +9 @ full throttle, both limit and delay pots @ 12o'clock, the PIT / PLT @ 12:30 o'clcok.

The linkages to the servo arms are in the inside hole, the 22E flys more docile after moving to the inside hole and a lot easier to control. Now my heli newbee friend can practice hovering with ease.
