Ivarb, I can identify with you and your Waco bipe. I used to have an All Star that gave me fits! I knew it would fly, if I could ever get it up there! It too was a tough little bipe, thank goodness, or it wouldn't have lasted as long as it did. Hand launched or ROG, it would start doing a fast tango with me trying to get "in step" on the TX! I finally just got fed up, set it on the runway, started it up, gave it some throttle and let it go. I didn't touch the throttle, just stood there watching it flying out like a drunk duck, waiting for the roll and dive that never came! The fool thing went up about 30 feet doing the drunk duck thing and settled down to gently climb away like an airplane should! I could not believe it. I landed and did it again, set it down, fired it up and let it go on its own. The same thing happened! One more time, only this time I set a tad of right rudder and it rolled away and lifted off and flew out straight as an arrow! After that me and that little bipe had some memorable times. After it finally had to be retired, I made a .40 size and it behaved exactly like its little brother once I got with "the dance!" I love bipes. But you got to treat the short coupled ones with respect, or they'll get you! Good flying.
