About this Plan

Gool. Free flight power competition model. The plan shows a 108 in model in full and also some details for a smaller 7 foot ROW version of the same design.

Quote: "Flying Models proudly presents complete constructional details and plans for the best free flight deisgn seen at the Nationals. Even if its size precludes your building this contest winner, the new ideas incorporated in its construction are worthy of your consideration when building other models.

In introducing this model we are not going to make the usual claim that it will average 55 minutes on a 7-second motor run in calm air. Instead, we offer you a time-proven reliable design, easily adapted to all rules and flying conditions, featuring ease of construction. ruggedness, and, most important, ease of repair - all desirable features for contest flying.

Our Gool is not a spur of the moment design - the first model was constructed way back in early 1941 and is still going strong after over 800 recorded flights!

The latest Goal, presented here, follows basically the same design as the original, with improvements that experience and changing rules deemed necessary. No contest rule changes are forseen that can cause any concern as to the model's future. Increased power loading certainly won't bother it, as we have been flying under 120 ounce power loading for years here in the Northwest. Our 9-foot Goal weighs 80 ounces the weight of the improved version presented here should run about 70 ounces.

If you have transportation troubles, lack of room, etc, the smaller 7-foot ship would probably be more desirable. The motor you own or plan to buy will also be an important factor to consider.

It's going to take a good motor to swing a 14 x 6 prop at the rpm's it takes to pull a big ship up. Small screaming props sound good and may look good for about the first 6 seconds, but after the initial burst of speed from take-off has petered out, the climb usually winds up as 60% noise. Therein lies the catch..."

Article, thanks to RFJ.


Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

* 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.
