Hi Fossil,
Sorry this thread got hostile but I hope it's back on track now. You say it's the yellow one? Thought at first you may have the ARC version but maybe someone stripped the covering. It's been a while since I've gone through this entire thread but I do believe there are some using the 120 FS or similar, I know there are some Saitos being used. The Ryobi is a little stronger than a G26 (26cc on the G26 I think) and will fly it with power to spare. The weight may be an issue, you're Ryobi is what....maybe 60 oz? the G26 is 53oz. I have the O.S. 160 FT in mine at 39 oz. The tail wire bracing is an easy fix. I used music wire and some tubing from the LHS or you can buy what the manual shows at the LHS. Same for the control horns...easy fix. If you need decals get some graphics cut to your liking. If you decide to sell you will have a bunch of guys jumping at the chance to have it.
These are only my opinions as I'm no expert by any means, you will probably get others.
