I'm still waiting to get a chance to maiden mine. I plan on pumping the retracts up to 100 psi, and pulling up the gear during climb out. I think the nose wheel door will be able to stay open under those conditions. I can believe that it would push back at any kind of speed, so it's important to bring up the gear before it gets going too fast. We'll see. Expect a maiden report from me in the next couple weeks if the weather cooperates.
