Wolfgang,
I thought about installing a bungee cord.
My problem is following. Having a IO390 I'm very nose heavy = and I=20 built my elevator trimtab 4" shorter. So coming in for landing = below=20 95kts
the trim is not enough. So I need to pull with 0.5kg to keep = the=20 plane in a stable descent.
I have 2 possibilities to fix the problem: I can either = install the=20 original spring trim or I install the bungee at the flap=20 actuator. 
Maybe the spring trim is the better solution because when you = change=20 flap position while landing you also have to adjust the trim tab = on=20 elev.
As I have a throttle quadrant and a glove box there is nearly = no room=20 for the spring trim. Maybe someone has a picture from a spring = trim=20 installed 
different from the plans of Lancair.

Christian


Has anyone thought about a = spring coupling=20 from the flap actuator th the elevator push rod=20 = ?
