Re: LA-4 amphibian.
I am of the impression that the elevator trim on an LA-4 is set up to overcome the high thrust line. I recollect something to do with the size and rigging of the horizontal stabilizer trim tabs and location relative to the propeller wash causes the aircraft to pitch nose down on a power reduction (ie engine failure) despite the high thrust line. The cost I understand is cruise speed - I've heard of pilots using a bungee on the control column in cruise to reduce the trim tab offset resulting in a faster cruise.
Can anyone confirm or dispel this?
