Default RV-6 Manual to Electric Trim Conversion

All,

Was looking to add electric trim to the elevator as a retrofit.

I've been through all the posts on the pros/cons of manual or electric so I don't want to re-hash that debate.

What I'm looking at is:
*Van's kit, which requires getting inside the elevator.
*I also noticed post for a Gretz Aero trim kit, which the company no longer offers (I contacted them Friday). I think this kit would be excellent, if you've got one lying around, lemme know $.

Has anybody invented a new way, or developed a good technique to get the electric trim retrofit done? Any help, pics, dwgs, etc. would be helpful. Thanks in advance.

Default Rv-10 parts

If you try to retro fit the standard electric unit you'll have to remake the trim tab as its actuator hole is in a different place and also you'll need to rebalance the elevator.
Another option might be to buy one of the rv-10 trim cables and remote mount the drive unit as its done on the rv-10. Then you wouldn't need to remake or rebalance. This basically the same idea as the gretz.
Check one of the many RV-10 builders sites and you'll see how it works.

This would be the direction I would head. If you look at Randy Lervold's RV3 build, you can see how he did it with the servo mounted to the aft deck of the fuse. This would lend itself well to a 6.http://www.romeolima.com/RV3works/

Does anyone know the length of the RV-10 trim cables (CT Q-43 )?

Thanks, GH

Wow - you have me thinking about doing this too. I think a custom (shorter) cable might be a better solution so you could mount the servo closer to the trim tab attach point. I'm going to go measure mine to see how short it needs to be. Come to think of it - you might be able to use a hard linkage for such a short run if the push/pull angle change is not too much.
