RCM Big Bird - Radio control sport trainer model. For .10 - .15 engines and 3 channels.
Quote: "The RCM Big Bird was conceived from the realization that we did not have an aircraft design to meet a much needed requirement. From the hundered of plans that we have available, what could be missing?
It happens to be a powered aircraft that could be recommended as the first radio controlled airplane project, particularly for a person who either does not have, or does not want an experienced RC'er to assist him.
We are thoroughly aware of modelers who will assemble their first aircraft and go out alone to make their very first R/C flight. The probability of success on this first unaided attempt is very low with the majority of the trainer type aircraft.
Dozens of trainers are available with varying degrees of complexity of construction. The Big Bird is simple to assemble even though there are a goodly number of detail parts. It was designed in this manner in order to keep it light yet strong, as weight is a key factor in the Big Bird concept.
Our approach is to combine low weight with generous wing area and a small throttle equipped engine to obtain a forgiving, slow flying aircraft. This allows the new pilot ample time to correct his mistakes before the craft smashes into the ground. In fact, with the craft at a reasonable altitude, if the pilot has managed to get the airplane into an awkward situation, he merely has to throttle back the engine, return controls to neutral, and the ship will right itself.
There are those people who will immediately say that the RCM Big Bird is a powered sailplane with a landing gear. Well, it is, in a way. The wing is a shortened version of the Bridi Big Birdy sailplane wing. The fuselage, however, is pure airplane, designed to be easy to build and rugged enough to withstand lots of abuse. The sturdy landing gear is usually found on aircraft weighing twice as much as the Big Bird.
The rank beginners aren't the only ones who can enjoy the Big Bird - several of our experienced flying friends have had a ball with it. Unbelievably small consecutive loops, tight turns, and wallowing barrel rolls, all in slow motion, have brought on lots of giggles. Because it is difficult for some of us to play a straight game, we dreamed up the engine pods for Cox .049 QRC engines to strap on the wings and have lots of fun with the phony Ford Tri-motor approach. Somehow we feel that having fun is what R/C is all about..."

* 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.
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.
