I just ordered an Adrian Page 60 size Gee Bee R2. He mentioned that this plane was designed for a Saito 91. I am having a hard time deciding between the Saito 91, Saito 100 and OS 91. I am leaning towards the Saito 100 since it is less than 1oz heavier than the 91. Any thoughts on this combination? Any suggestions on considering something else? Thanks in advance.

I know this is the ARF formum, this post started talking about an ARF, but I edited my first message to be more accurate.

I would go with the saito, for the 4 stoke sound. I always go with the bigger engine, it's easier to throttle down a little than not having enough power. Although there isn't much difference between the two engines.

I'm done framing up the wings on mine.. this kit is really nice once you figure it out All of the parts line up perfectly!!! (so far) I'm putting an OS 91 surpass in mine.. ol' reliable

Dean320,
I'd recommend the Saito 100. I built the Page GeeBee R2 and used my 100 in it. Fantastic combo. Flew really light althought I don't remember my all up weight anymore.
Check the strength and stiffness of the wood for the horizontal stabilizer, I lost mine due to high speed flutter when I tried to race a VooDoo Mustang. In my case, the wood was soft and I didn't use a long enough control horn. Since the elevator doesn't need to move much on this plane, I'd recommend using a long control horn and a short servo arm, or use the inner hole on the arm.
You'll like this plane, Adrian did a great job of designing light.
Anyone interested in fiberglass wheel pants? I bought them from Adrian but lost the plane before I ever got around to installing them.
