Hi!
I've heard some rumours that the electric elevator trim is very sensitive?
A way to solve it is to slow down the trim motor maybe?
We've installed the combined trimtab-horn on my left elevator, the one that followed with the emp kit. (The one that can be used both for manual and elec trim. One just trim off the part one's not using)
My plan is to fly a few rides with the trim rod attached to both the attachment points in turn and THEN trim off the one I like the least.
What does all of you aviators with flying RV's think? Is the trim too sensitive?
Best regards Alf Olav Frog

Using the tab for the manual trim isn't going to resolve a potentially fast
running trim motor. The matronic governor will. Theses governors can also be
used if you wish to operate two seperate bottons for the electric trim, as
in one on each stick for example. The governor is ground adjustable by means
of a screw. It is not recommended to do this in flight.

imho: Much ado about nothing. The problem is not the trim, it's the pilot.

Use the hole called out for the electric trim. I don't use a gov. on
mine and it it just fine.

I think the issue is too sensitive at what airspeed? Some have said it's
too slow with the flaps out (low airspeed) and too fast/sensitive at cruise.
Rocket Boy products and Matronics both make two speed relays to allow you to
cover both ends of the spectrum. High speed when flaps are deployed and
lower speed at cruise. They also cover, Pilot Co-Pilot override and runaway
trim issues.

Just build your plane and forget whether it will be too slow or to fast.
Fly it first and then decided for yourself.after you have a few hours on it.
