Tandem Bomber (oz3386)
About this Plan
Tandem Bomber. Radio control twin, for 2x .049 engines with single channel.
Quote: "The Tandem Bomber is a high-wing R/C model plane powered by two 1/2A engines mounted in pusher-tractor combination. With sport flying and the pylon racing events stimulating additional interest in R/C flying, this model should fit into many a modeller's program, if he is looking for something new and different.
The initial flight test of the Tandem Bomber was conducted under less than ideal conditions. The wind was more than desired but was relatively steady. A series of glide-tests were made before the correct stabilizer angle was obtained to prevent stalling. The tanks were then filled and the power unit attached to the model. Each engine was then started and individually adjusted for the correct fuel mixture. The tanks were topped-off, the radio was turned on, and both engines started. Prior to launching, the model was held long enough to blip the transmitter several times, while observing..."

User commentsit's the only plan ever meet expressely conceived for the very rare Cox RR1 that means "Rear Rotary" valve, this Cox had a very short and unsuccesssful life. It's one of the most sought engine by the Cox collectors. It was in gold color crankcase and blue tank, engine has round fins around thank and crankcase in order to facilitate the visual difference from the normal 049 elements for the factory personnel. Round fins are correctly drawed on the plan!

Dear Sir, attached you can find the finished "Tandem Bomber" flying model [pics 004, 005], my Coronavirus version (I mean 2021).
Nice day. From Italy,

* 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.
