Hey everyone. I'm just about to construct my elevator and was hoping to build an integrated trim tab into it. I've seen a number of planes with this mod, but haven't found any plans for it or even suggestions. Any of you have any experience you can share?

The V Max Complete thread which is current has pics, might try the builder for more.

I love my trim system, no tab needed and the elevator will not droop when parked.
Two springs are attached to the control stick, one pulling forward and one backward. The rear spring is attached to a cable allowing the tension to be adjusted by a dial.
All the articles about it can be found here:

Ulbuilder, that trim system actually looks like a good idea. Thanks for the link, I may go that route.
