Piper Tomahawk (oz9274)
About this Plan
Piper Tomahawk. Radio control sport scale model for .19 to .30 power. Wingspan 49.5in, wing area 400 sq in.
Quote: "Anyway, we thought the Tomahawk would make an interesting RC stand-way-off scale model. The low wing and tricycle gear are practical, the fuselage would be simple enough on a stand-off basis, and a practical T-tail construction method could be worked out. The biggest problem on a project like this is the bubble canopy. The model we built has a vacuum formed canopy we pulled, over a carved wooden plug. It wasn't too easy, and the plug is now destroyed - if we were to do it again, for a sport model, we would build up the canopy area from wooden blocks, carve to shape and paint the window areas with an airbrushed, mottled paint scheme. This canopy airbrushing technique was detailed in the September 1978 issue of Flying Models. The wingspan on this model is 49.5 inches, length is 37.5 inches. Wing area is 400 square inches, airfoil semi-symmetrical, and a .19 to .30 engine will suffice. We fly the model with a K&B .19 and it performs very well. Due to the T-tail construction, the model tends to be tail heavy so a larger engine would help the balance. The engine could be installed inverted and completely cowled in, but for sport flying we did things the easy way and mounted the engine upright. Wing flaps could be easily installed, using a torque rod linkage for inboard sections of the strip ailerons as the flaps, and using pushrod and bellcrank linkage in the wing for the outboard ailerons."

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

ScaleType: This (oz9274) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.
If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.
ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Piper_PA-38_Tomahawk
Wikipedia page addresses may well change over time.
For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.
Corrections? Use the correction form to tell us the new/better ScaleType link we should be using. Thanks.

* 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.
