I've got one and I love it. I've got a Saito 180 with Master Airscrew Scimitar 16X8 prop. Turns 9300 on 15% Wildcat fuel. This is by far the easiest plane to 3D. Its the only plane that I can control WELL in a TR. Does great elevators, waterfalls, blenders, full 3D snaps into a TR and anything else you can think of. Harriers are a little unstable, but I've only got about 13-14 flights on it. I had to add no balast at all. I put the battery pack on top of the tank. I'm running a 1650 nimh pack. The plane weighs 11.5 lbs.

It really is a great flyer. Lands quite slow also.
