About this Plan

Dream Machine. Radio control sport model.

Quote: "This classy little .25 powered low wing tail dragger will give you the performance in the air that you have been looking for.
Unlike a lot of other models, the Dream Machine was not developed and refined over a period of years and numerous design changes. Several years ago while visiting our son and his family, our 6 year old grandson, Gary, asked me to build a radio controlled airplane for him. Not having time to build it while visiting, I told him I would build a plane for him when I returned home.

Since Gary had flown my RCM Trainer .40, with help from his dad, I decided to scale down this design to a size more suitable for a .25 engine. I settled on 90% the size of the RCM Trainer .40, giving a wingspan of just under 48 in. (Subsequently plans for an RCM Trainer .20 (oz7631) were published in R/C Modeler, which is almost exactly the same size as the one I scaled down.) While building the trainer for my grandson I thought the wing would make a good low wing sport plane so, using the same wing plan, the Dream Machine plans were drawn. By the time I got around to building it, O.S. had introduced the O.S. Max .25 FSR and this engine was used in the prototype - this proved to be an excellent choice.

You often read, and hear, that a new design 'flew off the drawing board'; this one did. On the first flight no adjustments of any kind were needed and the plane flew like a dream. The wide stance of the main landing gear makes ground handling excellent for a tail dragger and no problems have been encountered on the ground. The prototype suffered a near fatal accident when it was flown into a pine tree in Florida.

That's enough rhetoric - let's build a Dream Machine.

Construction. Wing: Like so many others, I prefer making other parts of the plane, but since the wing is necessary, let's build it first. Wing ribs are 1/16 balsa. I cut all 20 ribs the same then modify 6 ribs (R-2) to accommodate the landing gear blocks. Spars can be 1/4 in spruce or hard balsa. Leading and trailing edges are 1/4 in square medium balsa. If you are using a wing jig, follow instructions for your jig. If you are building the wing on a building board, fasten the plan sheet to the building board and protect it with waxpaper or clear plastic sheet..."

* 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.
