RE: 1/2A SCALE PLANS
I built the Rearwin Speedster Rainedav posted above... from RCM 11/77. Great flier on a TD .049 and 3 channels: throttle (Ace throttle sleeve), elevator, and rudder. I scaled up the plans to a 48 wingspan since the original wing area would have made it too fast.
Lots of scale plans out there that would be fun to build. Scale plans are a ton of fun and fly very well, but they do require a lot more time and effort (well worth it). Also, they are a nice change from the boxy standard models commonly seen.
I also have a bunch of plans available if you are be interested.
