KR> Electric Trim
I haven't seen anything on here about electric trim, and I know lots of you have it! I'd like to go electric on the elevator trim, but don't know what kind of linear motor, actuator, servo, geared motor, etc. would be up to the task. Any information would be greatly appreciated! Thanks, Dave N1199P N8325M

Dave I have used a heavy duty model airplane radio control servo with a servo tester circuit as a controller. It hasn't flown yet so I don't know whether the servo is powerful enough. I tried the wing mirror servo method with a servo off a Jeep Cherokee, but I couldn't get it to operate fast enough.

I tried to use a r/c servo with a test controller, and it worked fine until the transponder transmitted, then it went to full deflection. If you use a r/c landing gear servo, it does not use a pulse modulation to control it, it might work. I went with a Ray allen servo, which works just fine. Al Hawkins Port Coquitlam, B.C.

Ray Allen probably is the best but, I went on the cheap side. I used 96 Toyota heater servo motors and Toyota Camary window switches. Seems to work fine. I also used the cables from the heater control off a toyota too. The motors and cables combined only weighed 5 ounces. --- On Wed, 4/7/10, Al Hawkins wrote: From: Al Hawkins Subject: Re: KR> Electric Trim To: "KRnet" List-Post: krnet@list.krnet.org Date: Wednesday, April 7, 2010, 9:31 AM I tried to use a r/c servo with a test controller, and it worked fine until the transponder transmitted, then it went to full deflection.

For this application, one needs to use an analog servo, not digital servo. John Melvin El Paso, Texas In a message dated 4/7/2010 8:32:28 A.M.

KR> Electric Trim Install
I've managed to do it - a retrofit - but I just have to ask!!! Are all of you guys just little guys? Or do you hire midgets, or use mini-robots, or bribe your kids, or what??? My access panel is just about large enough for my head. No arms in there, just the head! So, with extensive use of a mirror and a video camera, I managed to get the manual trim system out of there and then fit the new RAC system. Would I do it again? Well, yeah, I guess!!! But not for free!!! Dave. N1199P N8325M
