The main gear was installed at some angle forward using angular shims betwe
en =0Athe fuselage and the gear. That moved the ground contact point a few
inches =0Aforward=0A=0AThe trim tab was too small, I roughly doubled it in
size. =0A=0AJerzy=0A=0A=0A________________________________=0AFrom: Mark Ket

Tail Mod???=0A=0A=0A=0AI have VGs added recently, they help too, but I fee
l that an extra inch is =0Aneeded, making total of 2.5" extension.=0AMy tri
mmer is roughly twice the size of the original trimmer. With all of these
=0AI can trim ok for approach for landing, however the nose still drops dow

=0ATHANKS for the quick reply. I did a complete W&B back when I first start
ed to =0Atackle this issue. The airplane W&B is very well within the envelo
pe during all =0Aphases of flight. It is actually a tiny bit aft so I reall
y don't want to move =0Ait any further aft than it already is. That is why
I first started with the VG's =0Aand they made a big difference. But it sti
ll needs a bit more nose up authority =0Aat slow speeds.=0A=0A=0AJerzy, do
you have VG's on your elevator or just the additional 1.5"? Also, did =0Ayo
u extend the entire elevator to include the trim tab?=0A=0AGalin=0A=0AOn Sa

If I want to approach at an IAS of less than 90Kts I have to have full up
