I gutted one and re-stuffed it a couple of months ago. I suggest a matchbox and two 8611's on the horizontal stab.
I maidened said aircraft for it's owner about a month ago. The airplane was rock steady at any speed.
With full flaps I came in for an approach and everything was great. I overshot the runway and went carefully to full power. Just on climbout in a shallow left bank I "felt" the elevator go soft. I had been expecting to see something related to the elevator with flaps down.
I immediately came back off the power a little bit and raised the nose even more and elevator came right back solid.
So now I know
FWIW.
By the way, the landing by all accounts was the best one I've had in quite a while. It was a beautiful flight !!
