One of the things in the cockpit on the left side that affects other things is the trim handle. I need to know where it goes. Since the trim cable is made, the handle is at the forward end and the trim tab is at the aft end. But to get to the aft end, thereís this little problem - how to carry the cable around the horizontal stabilizer?
I asked VAF readers to let me know how they did it. Since many RV-3s seem to have electric trim, the information is a bit sparse. I got three replies and drew them on a section of Drawing 26 from the plans.
The red path was used by two builders. It fits under the empennage fairing, but requires somewhat of a deep dive into the stabilizer. On my plane, the cable will interfere with the ADAHRS and its mount which is in the tailcone just ahead of that bulkhead. Itís too bad because this is simple and fairly straight-forward.
The blue path was used by one builder. Itís a nice clean direct path except that it requires a hole in the forward spar. Iím reluctant to do that.
I chose the green path, even though I needed to figure out how to get the cable through the aft deck (the red and blue paths bypass it).
With a hole through the aft deck and a hole through the horizontal stabilizer root rib, the trim cable is in place. The lengthwise positioning of the cable is not correct, itís about 7Ē too far, but thatís been adjusted subsequent. The holes are too small and there are a few more minor tweaks to do. But this is the general path.
It was sufficient to let me find out where the forward end of the cable will be in the cockpit, and that was the purpose of the exercise.
The bulkhead fittings for the brake lines arrived and I drilled holes for them in the firewall. This is the first equipment mounting on the firewall, and itís now so that I can figure out the brake flex hoses from the cylinder (thereís one cylinder on the left) and mount those and the rudder/brake pedals. The circles show where they are.
This is my busy season so work tends lag a bit.
