I am a builder. But there are NO Extra 260 kits or plans in the 120 four stroke range. I found that Wildhare RC offers an ARF in that range. It is nicely covered, and I know Wildhare has a good rep, but I am more intrested in performance.

I built the GP Extra 300 60 size, and love it. Saito 125 for power at 7 1/2 pounds. It's a freaking rocket ship! The WH Extra 260 is 9 - 10 pounds, and is a bit bigger in wingspan and fuse length. I'd like to go 125 again, but fear it will lack in performance. If that is really the weight, I think a 140 would be a better fit.
Anyone have experience with this plane? Thanks in advance.
