As we plan to fly with Avgas in one tank and Mogas in the other, we will not use fuel evenly from both tanks. So we thought that aileron trim would be a good idea. We have a 4-way hat switch on the pilot stick for electric elevator trim. This led us to the idea to install as well an electric aileron trim system.
See former thread: http://www.vansairforce.com/community/showthread.php?t=86892&highlight=RV-8+aileron+trim
I liked the idea of the RV-8 aileron trim system with the springs, which does not need a trim tab and will prevent the ailerons from dangling in light wind. After I convinced my friend Markus, we ordered the RV-8 aileron trim kit from Vans.
After having a closer look at the system, we found some points that we did not like:
- Cotter pins to attach the springs to the aluminum rod
- Drilling holes in the push rod to rivet the attachment bracket
- Sliding of springs on the attachment bracked during rotation of the push rod
So we came up with the following solution:
- Stainless steel rod of slightly smaller diameter with brazed lugs for the springs
- Brazing the attachment bracket to a stainless steel hose clamp
- Brazing two small sections of tubes to the attachment bracket (for a defined position of the springs without sliding during rotation)
Brazing the bracket to the hose clamp
Modified installation in stainless steel
Trial fit in aircraft
…might be a bit over-engineered, but we feel much better with this solution ;-)
