Zee....make sure you have the guardian turned OFF the first time you fly it.
If you have never used stabilization, it will freak you out at first, making it seem like you have little input on the sticks. IE: full left aileron wont make the plane roll.
I always do the following:
1. maiden flight: guardian off, launch, trim, land.
2. go through ET setup again and redo all controls. (this resets level flight positions, which would have changed if you trimmed it)
3. launch, using a dial, slowly turn gain up on guardian, while displaying servo deflections. Make note of where your gain is when you have it turned up and its high enough for good flight, but low enough that your dont get osculation. land.
4. Go into guardian setup and set max gain to noted level.
