Could you please let me know if you have that info or recorded the range that you have Thanks very much Mike ________________________________ Message 2 _____________________________________ Time: 04:33:07 PM PST US From: M Ketteing Subject: Re: KIS-List: TR-4 Elevator Trim tab range of movement I have never seen a specified range for the trim tab travel. Keep in mind t hat if you followed the plans for the trim tab size, they tend to be way un der what is needed. Most people end up extending the trim tab. Since control surfaces tend to be fairly effective and linear to about 25 t o 30 degrees, this is what I would try.

But a lot is left to the builder. That's why they call it experimental. I can measure ours when I get home but not until Saturday.

What I can tell you is that the little trim tab can have a big effect. On one flight with a passenger trim went way up because his big bunch of keys in his pocket kept activating the trim, and I had to use a lot of force to counter it. Flew much better when he quit sitting on it. With the electric servo driven trim, you are limited by the travel of the servo. During test period, I verified that I could overcome full up or down trim in case of runaway trim. On Mon, Sep 18, 2023 at 9:07=AFPM Glenn wro te: > I don't think it's in the manual.
