Youvenko 1/2a wings wanted

Unless you have a high powered ball bearing .049 or .061, you won't be able to fly the plane.  My Yuvenko is current and it's wingspan is 37" tip to tip with a chord root of 11". This is larger than my old .15 sized combat planes. A TD won't effectively fly this plane and it won't balance it without tons of nose weight. Even a TD .09 won't balance it, it's close though.  

             These planes are indeed neat, they fly well but can be twitchy if you never flew them before. Hitting the ground doesn't usually result in a go back up and fly situation. The larger models do better than these do.

         I show a Mezjlik 1/2A combat wing as well. These were the best in my opinion and have been non existent for at least 10 years or better. A TD will fly one of these. The span is 30" with a 9" root. I fly mine with a VA MKII and it's a fast flying plane. I need some warming up before I go out and fly this one.
This is my Yuvenko, I had my outboard leading edge completely removed on it's first outing. I had to do some major repairs on this one but it's flying pretty well now.
