About this Plan

Simitar Classic. Radio control sprt flying wing model. A .40 - .60 powered Simitar with 1930s styling. Simitar Classic by Bill Evans.

Quote: "Often I am asked how I come up with ideas for a particular design in the Simitar (oz10187) series of model airplanes. Most of the time it is in hangar flying sessions with my friends in the hobby where someone says something that triggers an idea. A typical example of this was the Simitar Slo Motion which came from a request by Bill Winter for a slow flying Simitar.

The Classic, however, was the result of my sitting in my shop, wool gathering and reminiscing. I looked at the array of designs hanging above me and decided that I wanted one with more Classic lines of the aircraft of the late 1930's and early 1940's. These were low wing, single place with streamlining and a 'turtleback' fairing into the vertical fin. Some had air cooled radial engines and others had liquid cooled Vees or inlines. I opted for the liquid cooled type as it is better suited to the 2-stroke model engines. Also, although the full-sized aircraft of the era were all taildraggers, I chose to fit the Classic with tricycle gear because most R/C modelers find it easier to handle during take-off and taxi. So, now you know the genesis of the Simitar Classic. As to power, the ship will fly well with 40 to 60 size 2-strokes, but my preference is the K&B 48.

The Classic performs like all other Simitars, with aerodynamic stability over a wide speed range, no tip stall and full acrobatic capability. It will fly slow and easy for the beginner, yet it will rip at full power. Trim it out, come back on throttle and put it in a gentle turn, let go of the controls and it will continue to do 360s until you give it another command. This is a handy feature to give you time to get over the 'white knuckles.' We have flown the Classic in 40+ mph winds: it will hover, fly backwards, and land or take off vertically.

Enough of this hype. Now you want to build your Simitar Classic.

Construction. Wing: For those who do not cut foam, you may order cores for the Classic from Soaring Research, 454 Wildrose Lane, Bishop, CA 93514. (760) 873-4932. Cost of wing cores is $22.00 plus $8.00 for shipping. Make sure the wing panels are flat and straight; use weights with the core on a flat surface if necessary..."

User comments

I build the simitar classic, instead of the foam wing I've done a build up wings. Flight performance is everything Bill have saying. The only thing my classic comes out a little tail heavy. This not stopping the train, a little lead in the nose under the feul tank solved the problem. I'm going to do another one but will increase the nose length by 1-1/2 to compensate for the weight in the nose.
Best regards,

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.
