If your burned out, do something else, this is suppose to be fun! It does not even have to be RC related.

I agree with an earlier post about giving designing a try. I started with hand drawn plans (not cad) and slowly built a plane (this was 2002). After flying the plane, which flew great, I paid someone (relatively inexpensive) to convert the plans to cad and had a few laser cut kits cut which flew and assembled great. Since then, I've sold close to 400 kits which was never my plan.

The plane you want to design does not need to be complicated, it is very gratifying.
