Pluto - Radio control sport model for Cox Tee Dee .020 power and single channel.
Quote: "Pluto is a pleasing ship, both in appearance and in performance. It has been designed specifically for rudder-only work. It is a small model with a wingspan of 32-1/4in and weighs under 12 ounces ready to fly. The model is powered by a Cox Tee Dee .020 engine and employs the lightweight Ace Pulse Commander single channel equipment. In spite of the small size of the model, it is a very stable flying machine and can be flown in most weather conditions.
The model is very easy to trim. If properly built, in accordance with the plans, very little or no adjustments will be required to make the craft perform successfully. The prototype needed only a slight down adjustment on the elevator trim tab to fly properly. Also, once correctly trimmed, it is almost impossible to sustain extensive damage due to its light weight and relatively robust structure.
Because of the small size of the model, weight is of major importance to ensure good flying performance. Since the Ace Pulse Commander single channel system probably is the lightest radio control equipment commercially available at present, this outfit is recommended. The magnetic rudder actuator used in the Ace pulsing system is obtainable in several sizes and power output. My original model uses the Twin Baby actuator which is recommended primarily because of its low weight. The more powerful Standard actuator can also be used. If the Standard actuator is employed, the added weight of this unit will somewhat reduce the flight duration of the model. To compensate for this, it is suggested that you use a larger external fuel tank in order to obtain a longer engine run. The external tank can be placed in the engine nacelle pod. Normally, an engine run lasts about 85 seconds and the glide that then follows usually lasts another 3 or 4 minutes without a thermal. Under thermal conditions the glide flight of course, lasts much longer.
The construction is completely straightforward, but care should be taken to ensure that the balsa wood used is of medium to soft density if the design weight is not to be exceeded. This is important because you will note that the sizes specified for most parts are on the generous side..."

Did we get something wrong with this plan? That happens sometimes. Help us make a correction
* 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.
