Hello All.
Europa 914 Tri gear, Speed 125 kts in level flight, to keep the ball in the 
centre
i have to hold on left rudder.
The Rudder has a fixed Trim Tab which servo,s the rudder to the left ( same as
holding left rudder on)
But to maintain the ball in the centre i have to hold on more left rudder on and
hold the stick to the right,
If i look out at my left Aileron i can see its about the thickness of the tip 
trailing
edge down.
So i need more lift on the left wing to maintain lateral level. ( How can i 
achieve
this ?)
1. If i put a fixed trim tab on the right aileron it will servo raise the 
aileron
and keep the wings level, but i will have constant adverse drag 
maybe only a very small amount, Also will a fixed aileron tab effect the mass 
balance
of the ailerons, ( its only 4 x 1 1/2 of very thin alloy plate)
2. If i fix a Tab to the left flap outer edge, could i generate sufficient extra
lift to compensate, so the ailerons remain in line (neutral).
