I've got one of these that I've had for a year or so...
I love it...
I went to this from a 4 star 60. This thing is very stable in the air and at slow speed... Landings are a breeze with a blip of the throttle to keep it moving, won't tip stall! Keep the control throws low to start!, you don't need much elevator, and it will snap easily with too much!
I did lateral balance mine with about 2 oz's on one tip...
I started with an OS-160 and it was 12 lbs. A real nice combo, but I could not keep the engine cool enough... I will disagree with the comment about it's dead stick flight quality... With the 160 on it I had a dead stick on quite a few flights, and I had no problems, in fact, it is one of the better dead stick landing birds I have flown due to it's slow as a walk landings... Keep the nose slight down and you're good. I switched to the G23 and i'm not looking back. With a 15-10 prop it flies well. It is somewhat under powered, but really it makes you FLY through a manuver, which is not a bad thing.
Best thing is that I can fly for 15+ minutes on 8 oz of cheap gas... My OS would suck down about 1 oz per minute, and I think the Saito is worse...

Anyway, to move up to a 1/4 scale this is a great plane. I just sold a Great Planes Giles 202 with a 160 on it, and that plane flew great too, but you need speed on landing, much more than the Edge...
I like the Edge so much I'm building a 33% aeroworks now.

Good choice, you'll enjoy it.
One tip, have an experienced guy (or girl?) check fly it & give you some feedback, you'll be glad you did.
