Anyone have pictures or documents         on converting one of the older (-4, -6) elevators to electric         trim?

         

         I'm contemplating the change on my flying -4 & I'm wondering         how much of a hassle it will be to modify the elevator. The         elevator is already off the plane for another issue, so the 1st         step is already done. 

         

         I'm aware of the need to re-balance; I'm more interested in         whether I'll need to remove the stiffeners around the current         manual trim, & how much structure needs to be fabbed &         added for the trim motor.

         

         Thanks,

         

         Charlie

Charlie, Warren GREtz used to sell a conversion kit.  I don't see it on his site and furthermore his site seems defunct.



However as I remember it, it was very simple and didn't require any rebalance at all.  He simply mounted the servo motor on the stabilizer deck and used a short flexible link to the old trim tab.  I can't remember what the link was perhaps a bowden cable?  Hopefully someone will remember.

I liked it better than the old Van's system which had the servo mounted in the elevator (mine is such in an RV 6A).

Hi Charlie,

I just did this very thing on my circa 1994 RV-6, The Flyer.  I installed a servo under the fin and ran a short, standard green control cable to the original trim tab and horn.  Works GREAT!  Attached are some pictures of the retrofit.

Thanks Matt; the trim tab end remains as Van designed it? Do you recall 

where you got the short control cable?

Thanks,

Charlie

Charlie,

     Come down and look at mine.  Unless your elevator is really     different it should be a "relatively" simple conversion.   The servo     is so light that balance of the elevator my not be effected.
