blvd- use retracts servos only, the standard servo will not work. You will need two of them, one on the mains and one for the nose wheel. I'm using Hitecs and they have plenty of power. If you do eventiually go to the Hobbico, it will require some surgery on the nose area, but for me, it was worth it. Now, my only problem is keeping the covering tacked down, it is tending to lift when out in the sun,but that is easy. Just keep the heat low on the iron.
