I have to tread lightly here becase I know a lot of people have spent a lot of money on trim servos, but I still maintain that a very simple pushrod system like I have on the third picture in this page http://www.engalt.com/flight1.htm is more than adequate, easier to use, and a whole lot cheaper.
If I was building another KR I probably would put in elevator, aileron, and rudder trim tabs with electric servos connected to a home built 3 axis autopilot connected to a Dynon. -----Original Message----- From: krnet-boun...@mylist.net [mailto:krnet-boun...@mylist.net]On Behalf Of larry flesner Sent: Wednesday, March 17, 2004 10:02 PM To: KRnet Subject: KR>Aileron deflection/pitch trim >I've seen some planes where "neutral aileron" actually was both ailerons >sagging almost an inch -- when the plane was at rest.

I spent $210 for an electric trim servo just to take the "wiggle" out of my mechanically operated pitch trim tab. Speaking of pitch trim tabs, there was a discussion a while back about saving youself using pitch trim if the primary pitch control were to fail. Using my Ray Allen servo (formerly Mac), I'd give myself about a one in one thousand chance on ever pulling that off and I'm probably being optimistic at that. It's too slow and too far behind the aircraft movements to ever make it happen. I've tried it several times and after about 20 seconds I've basiclly lost it. That's one of those things that sounds good in a conversation but IT AIN'T GONNA HAPPEN !! I think I could pull it off in the Tripacer but not the KR.
