Tri-Q Plans Introduction


The Tri Q conversion was developed for the average pilot who learned in a conventional nose wheel airplane.

The plans were developed after the installation was proven in actual flight testing by us. We tried to make the plans as easy to understand as possible but as always, parts of them may be difficult to comprehend for some people. We suggest that you go over the PLANS, DIAGRAMS, AND PICTURES, a few times before jumping into it. The main thing is to try and understand basically what you will be doing before you do it so everything will fall into place. While you are building, constantly refer to the diagrams and pictures to help clarify the words. If you are still having trouble with some part of the conversion, please call me and I will be glad to help you in anyway I can.
