Don't just bend it back. If you do that, I seriously doubt you will be happy with the feel of the stick.

The main differences are switch placement, ratchet on the throttle, and a magnet on the low point of the throttle stick. The magnet keeps the left stick sitting at the low position and prevents a bump from advancing the throttle I suppose.

What you want to do with the ratchet is remove the back cover of the radio and set it aside (leave the wires connected). Then, undo the screws holding the metal ratchet tension piece. The heli version has this same basic item but instead of having notches, it is smooth. By tightening down the two screws, you increase the friction on the stick. For the airplane version of this radio, I flip that metal tensioner around and use the back side of it. You will need to slightly bend it opposite of the natural curve and then reinstall it. Hold the radio and get a feel for the stick, adjust tension to your feel. Smear a slight dab of vaseline on the contact point to keep things feeling smooth.

I didn't have the time to try and play with removing the magnet but it annoys me. My bro has the airplane version and he flies helis with the magnet in there, you can feel it a little if you happen to pump full negative but other than that it feels fine. If you just loosen up on the ratchet, you get a sloppy stick that is way too loose to have a good looking flight imo.
