Wolfgang,

I thought about installing a bungee cord.

My problem is following. Having a IO390 I'm very nose heavy and I built my elevator trimtab 4" shorter. So coming in for landing below 95kts

the trim is not enough. So I need to pull with 0.5kg to keep the plane in a stable descent.

I have 2 possibilities to fix the problem: I can either install the original spring trim or I install the bungee at the flap actuator. 

Maybe the spring trim is the better solution because when you change flap position while landing you also have to adjust the trim tab on elev.

As I have a throttle quadrant and a glove box there is nearly no room for the spring trim. Maybe someone has a picture from a spring trim installed 

different from the plans of Lancair.

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