This plane was a little bit of a departure for me in a few ways. First, it is an Old Timer design and while I've always appreciated the looks of Old Timers, this is the first one I've built. Second, this plane is actually a free-flight kit and I converted it to R/C. Third, I typically build fast, aerobatic planes and this design is more of a slow flyer. This plane was built from a kit by BMJR Model Products (http://www.bmjrmodels.com/). It is a reduced size version of a 1938 design, but upon reviewing the original drawings they stayed very true to the original other than the size. The kit (and the original) has a drop-off launch dolly which I omitted due to my flying mostly off of grass. The conversion was fairly painless; there is ample room in the fuselage for all the electronics and the tail size was appropriate for R/C control surfaces. I reduced the wingspan to 32" to help with fighting the constant winds here, built new tail surfaces for R/C use (same profile as the originals), added an outrunner motor and built up the nose around it (the motor is removable though). I scratch-built a fake glow engine just to keep that true Old Timer free flight look going :-) The project was a lot of fun and the plane flies absolutely FANTASTIC!! It's surprisingly aerobatic for rudder/ elevator, will climb vertically indefinitely and floats like a leaf when the power is shut off. It can handle a surprising amount of wind. It gets bounced around a bit in gusty wind, but it tends to return to neutral flight on its own. I've got about 20 flights on it so far and it never fails to bring a big grin to my face!
It is equipped as follows:
PJS 300 SF outrunner motor
APC 8x6 prop
3x620 Vampower pack
GWS Pico servos (x2)
Wingspan is 32"; weight without battery pack is 5.4ounces, 7.0 ounces with battery pack
Covering is SoLite (trans. yellow, white, dark blue trim, silver windshield)
Run times are around 20 minutes in dead air. I think this little plane is going to be an awesome thermaller, but I haven't had a chance to try that out yet.
Many thanks to Ronnie for these awesome in-flight photos that he took at DEAF 2006. I wish I had gotten the battery hatch on there, I had left it off during testing and didn't realize the plane was going to be photographed. The photos sure are nice though!
