FWIW, the adjustable trim on a plane should be able to effectively compensate for all loads from the forward to the aft limit of the allowable CG range. If it doesn't then you are dealing with a design issue you might want to consider correcting. After rebuilding the tail and correcting the incidence of the horizontal stab, then adding an electric operated trim tab to the tail, my KR will trim to any speed from slowflight to cruise anywhere within the acceptable CG range.
I get it. Our KRs have very light controls, and you can fly an out of trim KR for years without issues. I did the same for a number of years while I experimented with various trim systems on my KR. But when you look at certification specs for aircraft, you should have sufficient trim available to attempt a landing should you have a failure in the elevator control system. That was the standard I built mine to when I rebuilt the tail. Then I went out and tried it. No, I don't think I can successfully land the plane with trim alone without significant damage to the aircraft. But I believe I could do a survivable landing with trim and throttle alone. I'm not saying everyone should rip the tails off their planes and build them to certification standards. However, there are reasons for those standards, and it's worth putting some thought into how the aircraft may handle under abnormal circumstances. -Jeff Scott North Arkansas _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/[email protected]/.
