I flew my GP DR-1 today for the first time. About all I can say is that it's awesome. I even performed a no damage ground loop on it's maiden flight. Just like many of the real ones! Landing in about a 7 mph head wind, the plane was carrying nealy no groung speed when I sat it down. The second flight was flawless.

I found the rudder to be very effective in the air. Mine actually flys well flying the rudder and using the ailerons to maintain the desired roll angle in the turns. And es, it will do some amazingly tight, slow, flat turns.

As far as the OS .61FX, I strongly recommend a 4 stroke. The sound is so much more realistic on a plane like this. Besides, the plane is not the type that you can do a whole lot of aerobatics with. Though it will loop, roll and spin.

The gear are narrow, a cross wind or gusts get tricky, but there's not a thing you could change to make that any better unless you'd could rewrite history. I must say, hats off to Great Planes on this one.
