What plane for my OS 20?
Any suggestions for a low wing aerobatic plane for an OS 20. I would prefer a kit but am not opposed to scratch building something. I was looking at the Lanier Extra 3.25. They recommend a 25 2 stroke though and I guess I am not sure if my 20 would be enough. Any suggestions. Thanks

RE: What plane for my OS 20?
Hello,
I just finished and test flew my little House of Balsa P-51, it has an old OS .15FP and flew just awesome, it calls for a .20 so that would work great. I built it light weight with dual micro servos in the wings and left off the scoop on the wing underneath. She moves great though the air, it would have been nice to put some retract on her, but she looks good cutting through the air. I have two flights on it so far. I was nervous about the handling characteristics of the small scale bird with rumors of tip stall tendecies etc., but to be honest this thing has no bad habits. The stock elevator gives a huge amount of throw, so its really pitch sensitive which can be sporty on landings, but I cant wait to get her back in the air this weekend! Pics below:

RCM plans "Miss Bikini", designed by Chuck Cunningham for that size engine. Low wing, open cockpit, tail dragger with wheels widely spaced on the wings for good ground handling, symmetrical airfoil, 45 inch span with a pretty broad chord, very aerobatic, looks good. Probably 7 bucks for the plans. Looks like an easy scratch build, but haven't done it myself. Saw a rave report on its flying characteristics somewhere. Jim

Buzzard,
Of course I had to go look at it. Very nice looking plane.
Here's the link in case anybody else wants a peek;

My pleasure, Brady--if you build it I hope you'll tell us about it and show a few pics along the way. Seeing the link reminded me that I've wanted to build that plane myself for quite awhile...and I have a couple of unused .25s lying around. Jim
