I have an old OS25 SF that I want to stick into something relatively fast. A bunch of guys at the field are flying some of the GP 1/2A mustangs/corsairs and another guy just got one of the WildHare LR1. I'd like to stick with something with a landing gear, so the GP's are probably out. The LR1 has my attention, but at $160, it'a a little pricey. I think I'll wait and see how my friend's flys 1st. Another guy mentioned a Viper, but a 25 would be at the low end for an engine. What else is out there to turn-and-burn with?

There was a guy at my club a few years ago that had a Sig Kobra with a .25 and a tuned pipe. I don't remember if he had gear on it or not since I watched him hand launch the plane. It just screamed! I think Sig rates the plane for a .19-35. It appeared that he built it lite and took advantage of a smaller, lighter and more powerful engine. It would take some careful consideration on what you put in the plane, but I think the extra work would pay off nicely. Besides, it isn't a bad looking airplane.!

Another thought would be a plane called "crazy thing" It is sold by a small company in Wisconsin called precision aero. I built one and started with a very old tired OS .25 FP. It was fun to fly but I made it much better by switching to a Fox .15. The crazy thing was my trainer for flying a Patriot powered by a YS.45. The only bad side to the crazy thing is you have to hand launch.

Hope this has been helpful!

You could always try something like the herr engineering 1/2 a planes, but you REALLY have to beef them up, they are made for small engines but it can be done, I had thier 1/2 A texan with an OPS .21 in it and it would scream, but like I said, you'll have to beef it up, A LOT! Something like the House of balsa planes could work too.

You could put it in a Sig Wonder.

I guess I should have mentioned I was most interested in an ARF, but the Wonder looks interesting. Just finishing up another DC F20 and I really didn't want to start building anyything else this summer, other then repairs
