RE: ESM Dornier DO 335
Correct. Don't rush.
I bought the expensive Sierra retracts and during taxi trials one of the wheels kept locking up. I scratched my head on consecutive Saturdays trying to figure out the problem. Turns out I needed a different axle grease. They've been perfect ever since. Moral to the story...take your time.
The flaps, retract, brakes, motors, lipos, steering, plane balance, etc need to work perfectly before you give her full throttle.
Also, My brakes from Sierra had a very cool proportional valve. I hooked it up to the elevator. The more I pushed up, the more it gripped. Very nice...but brakes will add more weight and will require a whole new balancing.
One final thought...I'm a chicken ****. I never maiden my own planes. I'm lucky to have some very good warbird pilots at my club. I find the team effort works for me.
