To each his own....
I fly mine with a Saito 100....it pulls out of a hover fine.....does it jet out? No. Does it pull out like a 35 % Edge with a DA 100??? Yes. I believe power to spare is awesome....but so is a light plane....A OS 1.60 on this plane would just be silly. It is not worth the weight that it would add......but like I said. To each his own.
This plane is awesome with the Saito 100. It flies, to me, like a 35 % Edge......low wing loading, all around great flying plane.
Yes, it does have SERIOUS roll issue with the massive rudder. I'm not use to a rudder this powerful....I'll figure it out though.....
