I just maidened my Reactor today (no cowling, no decals, just couldn't wait). Only 2 flights with a rich engine setting. Power is a Magnum .52 2 stroke and it's still not fully broken-in. The plane required a few clicks of up trim and one click left aileron. My initial impression is AWESOME. I installed the stock lg backwards and it actually looks cool. Contrary to what has been said, I experienced no problems whatsoever taxiing, taking off and landing on our grass runway. This is the first 40 size plane I fly in quite some time, but it's definitely a keeper!
