(Charlie England) ________________________________ Message 1 _____________________________________ Time: 05:42:41 PM PST US From: Charlie England Subject: RV-List: electric trim conversion docs?? 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 ________________________________ Message 2 _____________________________________ Time: 06:12:42 PM PST US Subject: Re: RV-List: electric trim conversion docs?? From: Denis Walsh 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).

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.
