I used bowden cable to actuate the trim tab on DE Stubby.  I installed and routed the cable into the elevator to allow it to bend easily with elevator movement.  The other end is attached to a lever at the top of the cockpit.  The lever pivots on a bolt that has some split lock washers to provide some friction.  Works great.  I think this arrangement is simpler than the cable/pulley system in the plans.
