Albert, mine drops the tail to. When the tank is full OR the engine is running the tail will stay up.
I guess there is enough prop wash at idle to keep it up. Neet thing on this when you get to fly.
I like to do touch and goes without touching the nose wheel. Also , preinstalled in the tail are
blind nuts for a cleet tail wheel. Thread a nylon bolt into the rear one to save the Ultracoat
on the tail. Finally be carefull not to overtighten the wing bolts. The bocks can be easly split.
