(CBRxxDRV@aol.com) ________________________________ Message 1 _____________________________________ Time: 04:52:51 PM PST US From: Dave Durakovich Subject: RV4-List: Electric Manual Trim? --> RV4-List message posted by: Dave Durakovich Been lurking for awhile, and decided it's time to come out of the closet! As a new builder of a -4: Old airplane, started in 1989, I'm the 5th owner, and probably only the 2nd owner to actually do anything, This bird probably has more miles on it than my Cherokee, Nearly done and I still have more pieces than I know what to do with! I'm at the stage of installing cockpit controls. As acquired this bird was set up with the manual elevator trim. And while I have nothing against the manual trim, I'm not thrilled about the location of the control. Hence, my question. I realize I can pull the existing manual push/pull cable out and go with a servo. However, since it's already there, what about just mounting a servo in place of the manual lever? There seems to be minimal drag on the cable alone, and I may need to fab a bracket to get the correct travel. I suspect there will be little weight penalty, if any, but I'm just not sure of the additional force required. Has anyone tried this? Any of you guys out there want to venture a guess?

I figure it was done the same time the owner added electric flaps. There is no trim handle, makes service easy I would guess. It seems to work just fine.
