RE: Balsa USA 1/3 Scale Sopwith Pup
Fellas,
Several years ago I flew a Balsa USA 1/3 scale Pup. It was built pretty much like the plans called for with a few scale touches added here and there. The flight characteristcs were fantastic! It looped, rolled (both snap roll and axial roll), stall turned, wingovers......pretty much the same manuvers that the full scale plane could do with a few more that the early pilots hadn't even thought about.
The difference between the smaller models and the 1/3 scale Pup is that the third scale Pup must be flown through the manuvers, in particular, the rudder must be used a lot! I was even able to do a rolling circle with mine. Don't be afraid of it......just take it up really high and give yourself a chance to learn the flight characteristics. Just remember, if you fall out of a manuver, back out of the throttle and slowly regain level flight. Just thinking about that old bird makes me want to get another one up and flying again!
