My Schoolgirl had a short life span. Built in 1964 from the Top Flite kit, I used the exact same control system shown on the plans, a Babcock escapement for rudder and kick-up elevator, plus a second two-position escapement for throttle. You had to be pretty fast on the button to get all this to work from a Controlaire Mule transmitter. One click was right rudder, two was left rudder, three gave you slight up elevator, and a quick blip actuated the second escapement for throttle. An add-on exhaust throttle for the Cox 049 gave two positions, wide open and idle. This was cutting edge stuff for single channel back in the day, when it worked that is. My Controlaire single channel receiver worked most of the time, but unknown to me, it was sensitive to RF noise caused by the vibrating metal to metal contact in the throttle linkage. Nobody realized there was such a thing because it was unknown with the previous super regen receivers, which noise didn't seem to bother. Mine did funny things when the RPM of the engine was just right, making solid control impossible. Before the first flight, mine had an incident when I was running the throttle up and down in the front yard. It got away from me and headed toward the street with me frantically quick-blipping the transmitter button. About that same time an old man in an antique Plymouth Mayflower appeared around a curve in the street. All I could see of him was white knuckles and bald head a few inches above the steering wheel. He never saw me or the Schoolgirl as she disappeared under the Mayflower. Any other car would have shredded the Girl but the Plymouth's big tires gave enough ground clearance to cause only moderate damage. The bottom wing didn't survive but the rest was repairable. Everybody knew she flew better without that pesky bottom wing, so that's how mine continued, the poor power of the Cox wasn't quite enough for a biplane anyway. While the tough ol' Girl did fly well, she succumbed to the erratic radio system and only lasted a few flights. If I were to build another, I think I would go with a built-up wing construction, the nice wide balsa in the Top Flite kit no longer easy to find.DougSmith - 20/09/2016

Notes
* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
Scaling
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
