KR> trim tab size
It starts with at a ring hook under the pilots left on the left side of the front spar, spans to the center through another Clevis, goes up the front spar and the other bungee end hook goes around the center control stick. By sliding the bungee up and down the stick I can adjust the force needed.

KR> trim tab size
I just ordered a Ray Alan trim tab servo from Wick's and they have all kinds stick grips that will work with the servos.

>The reason I know is because in N56ML, the three LEDs slightly >"north" of the middle are dead on mine, killed by radio frequency energy. +++ My LED indicator got toasted early on like Mark's, probably from radio frequency overload. I was going to replace it but decided not to bother as I never referenced it anyway. As I recall, I made my trim tab the size called for in the plans. I seldom see it deflected more than about 1/3 deflection after landing. My KR is stretched 24 inches so I may not need as much trim as some. I do get a noticeable pitch change when I deploy the speed brake full down and trim for that. I do not reset trim for takeoff but adjust trim on climb out or cruise as necessary just as in a Cessna or Piper. You will find that you will adjust trim by the feel in the stick, not by the lights. On your first flight just take off with neutral trim and precede from there. Stick forces in the KR are so light that it's not an issue. Larry Flesner
KR> > trim tab size/Ray Allen
My KR is stretched 24?inches so I may not need as much trim as some.. Larry my KR2-S is stretched another 18.75" farther aft of the rear spar. Yep you read that right...extended one more bay plus four inches to the leading edge of the vertical stabilizer spar -bulkhead.I think my KR2s is the longest in the world. I hear long is a good thing so in this case I can brag mine is longer than yours. Who needs trim when you have a long one? ?I think I might have opened a can of worms with this subject (trim and longer fuselage).Thanks Larry ?Joe Cruzcruzj12 at frontiernet.net On Monday, May 12, 2014 11:09 PM, via KRnet wrote: >The reason I know is because in N56ML, the three LEDs slightly >"north" of the middle are dead on mine, killed by radio frequency energy. +++ My LED indicator got toasted early on like Mark's, probably from radio frequency overload.?

Without sitting in my plane and looking, I'm pretty sure all elements are lit except the trim tab position, otherwise you could look at it and still not tell exactly where you were on the scale. As for how big, one factor is will you have flaps or a belly board, and if so, do you care if it's trimmed properly for landing. And also, do you have a header tank that will result in a "volatile CG", or do you have wing tanks that will have a much smaller CG shift during flight typical flights. I built a small tab, and never used more an a third of the whole scale at max CG change, but it wasn't enough to counter the flaps' effect during landing. Give us a little better idea of the rest of your setup, and somebody with something similar can probably answer the question better. There's more on my trim tab at http://www.n56ml.com/trimtab/index.html . It has details on deflection, among other things...
