REFLECTOR: Elevator trim

[nmflyer1 at aol.com]

Scott, 

Not like you need another thing to do:  You could always pop the rheostat out and measure the resistance at the 2 settings that you like. Then you could wire a switch to do just that. The only reason I suggest it is that if you do this..... I'd appreciate the numbers :)  

Back to sanding.... Elevators/canard done and hanging on the wall.

I agree with Lou.  I am using the factory setup actuator combined with the Strong Control Circuit which has a speed control and brake.  Best of both worlds in my opinion.

Setting the speed to slow allows for much easier hands off trimming at cruise and setting it to fast allows for the same ease at pattern speeds. I would actually prefer a 2 speed switch instead of the rheostat the Strong  system uses. I have two marks on the rheostat and its always set on one or the other.

Ron I put a speed control on my elevator trim and it works great. The problem I had was that my electric trim was too sensitive. I would trim up just a tiny bit, then I would have to trim down, and the cycle repeated itself. I don’t remember which speed control I used but there are several out there. Here is how mine works. When you hold down the trim switch, the motor is slowed down so that you can control a smaller movement. If you hold down the trim for three seconds, the motor speeds up. This helps for major trim when landing. I believe my unit came from Jack Wilhemson 843-884-5061

Now before I jump off the and put this Dynamic braking on what is the censuses on the performance 
of this add on . Since I am so new to fling the velocity  and am working through so many other issues 
at the same time Cooling, oil levels, plane performance and the like .
I do not know if this is a really needed  mod or not yet though it seems like my plane may need it . 
I have done a little investigating a speed control device for the trim also.  Does the speed control 
help more or would a combination of the two really help
 
Brett Thanks for the pointing out the wiki I tried searching the reflector archives with no luck .

If you have the strong trim, please make sure you're compliant with the AD.
