The stock gear is fine if you add a threaded rod between the legs to stop them from spreading. Also, add some epoxy inside, around the wood the gear bolts to (I do it to all ARFs)

The plane does "stick" to the ground because of its low angle of attack. Put flaps on a switch.

Flick the flaps on for a perfect takeoff and flick them off after a beautiful climb-out. Simple solution.

Nice flying plane.
