Setting wing and thrust incidence
 

I've built many planes and have always built on a flat board and the planes came out ok, but now I'd like to fine tune them a little better. What's your favorite way to set up wing ,thrust, and stabilizer incidences? How about the GP Accupoint? or?

I use the Robarts incidence meters. One cannot argue with a spirit level. The needle is also useful and usually accurate. I use three meters, then I do not have to move anything. With the airplane assembled I block up the wing and fuselage to set the wing to the desired incidence. With a second meter I set the tail. For the engine I use a piece of tubing that is a slide fit on the crankshaft, this tubing has a small spirit level glued to it. All three meters are then on the airplane at the same time and differences are easy to see.

For the airplanes I build I do not need a graduated engine meter. It would be easy to mark graduations on this spirit level if I wanted to do so.


When joining wing halves I use three robarts meters, one at the root and one at each wingtip. This prevents me from building a propeller.
