I searched through the threads and found a few discussions on the topic of elevator trim solutions but I'm still undecided as to which approach I will take for the RW19 Stork that I'm working on.
Top speed for the Stork should be around 100 mph but the elevators are pretty big with a lot of surface area.
Trim options :
1. Trim adjustment in the cockpit on the stick.
2. Trim tab on the elevator using a 20kg rc servo built into elevator driving a pushrod to the trim tab,servo driver mounted in cockpit for servo adjustment and a converter to change 12v to 6v to power the system.
3. Trim tab on elevator actuated by a cable that runs to a lever on throttle quadrant.
I understand that a elevator trim tab with play in it can cause flutter with serious results.
I'm not sure how to make a trim adjustment on the stick but maybe someone has a design they could share.
Opinions as to which route would be best for elevator trim.........stick or trim tab ?
