Engine for .46 U can do

I am having trouble trying to decide what engine to buy for this plane. I was thinking Saito 82,91,115,125 and the O.S. Fs95v. The plane has been out for several years and the manual suggests an O.S. Surpass 70fs II but those are heavy and discontinued. If the plane can take that kind of weight (22.1oz with muffler) I figure why not go for more power with the newer lighter four strokes in about the same weight range. I know you cant overspeed these planes or the come apart but I love an overpower plane with unlimited vert and plenty of bail out power. I have a Tribute 36 with an O.S. 46 ax on it and love the power of that combo, also a Mojo .40 with a 55AX and love that power. I don't want to be disappointed with the power of the U Can Do and I know its about a .60 size Plane even though its called a .46 and I want to try a 4 stroke because I never have flown one. Suggestions please!

I had an OS 91FX on my Ucando 46 and I loved it! Go big, prop it so it wont fly fast as the airframe cannot handle high speed. Good luck and enjoy!

I was leaning toward a 4 stroke because I have all 2 strokes now and would like to try something different. The FX is discontinued unfortunately and the 95AX is about the same cost as a 4 stroke. How did it balance with the FX on it? I see the weight is almost the same as the Saito 125. Did you have any trouble with flooding or hard tuning due to the motor being inverted? I have never messed with an inverted motor yet and wonder if I need some sort of regulator.

Balance was not an issue, I did not have to add weight to the tail. With the motor being inverted, I had to be careful when fueling, but tuning was not a problem, the engine ran great.
The Saito125 would be a good match! I think you will be happy, the plane can handle a lot of wind and is a blast to fly.
