Whiplash (oz7767)
About this Plan
Whiplash. Radio control sport model. Uses a foam core wing.
Quote: "If you were in it while it was flying, you'd understand how this plane got its name. Whiplash, by Dick Sarpolus.
If weather conditions in different parts of the country have an effect on aircraft designs, then the Whiplash is a result of our northeastern (New Jersey) winter climate. I am primarily a pattern competition flier, and after the last contest in October, I hang the current hot ship on the workshop wall until spring. I just don't enjoy serious practicing in cold, wet, windy winter weather - l'd rather not risk a good pattern aircraft in casual fun flying.
Our club field does see a lot of winter activity and, without the contest season pressure, it is a lot of fun. Because of the weather, our winter flying is done a little differently - we don't plan on a whole day at the field. Much of the time is spent with hot coffee in a handy car.
For this type of flying, a small, easily assembled plane (especially one that will fit in the car assembled) is a real advantage. We observed some fliers who flew powered gliders exclusively and, while this was not what we wanted (can't practice Class C maneuvers with a glider), the simplicity of hand launching appealed to us. Elimination of landing gear would further simplify the plane and enable better performance with a small engine.
One characteristic we had to have to allow pattern practice was full aerobatic capability. To be competitive in Pattern, you must fly a lot. To do all the flying with the same aircraft would, of course, be ideal. However, that is not a necessity. The important thing is to fly something that will perform all the maneuvers.
Don't think that these desired charcteristics result in a hot, 'experts only' airplane. The Whiplash is not a basic trainer, but it did turn out to be a good intermediate ship. Anyone who can fly basic ships like the Falcon 56 (oz2424), J-Craft, etc can fly our Whiplash. And the expert flier can have plenty of fun without worrying about his top contest ship.
We settled on 19 power to keep the size down and still achieve acceptable performance. We would be using four channels, so the equipment weight would be considerable..."

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

Notes
* 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.
Scaling
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.
