Elevator, measuring at stab counter balance as it’s shown pic. #3 a. You should have 4 ½
in. up and down.
Aileron, measuring at the aileron root as is shown in pic. #4 a, you should have 3-13/16
in. up and down. Please remember that both ailerons should move the same up and down.
Rudder, measuring at the counter balance as it is shown in the pic. #5 a, you should have
5- 3/16 in. right and left.
Once you finish with the maximum rate adjustments, it will be the time to adjust the low
rate. The low rate value is the one that you will use for all your flying except for the
3-D. These values that I am going to recommend to you are good compromising numbers
to balance best with minimum radio programming set up for all spectrums of the Aresti
maneuvers.
Elevator, measuring at stab counter balance as it’s shown pic. #3 b, you should have 7/8
in. up & down
Aileron, measuring at the aileron root as it’s shown pic. #4 b, you should have 3 3/8 in
up and down. Please remember to check both ailerons so they are traveling the same
distance up and down.
Rudder, measuring at the counter balance as it is shown pic. #5 b you should have 2 5/8
in. right and left.
Now that you have adjusted the high and low rate let me gave you the exponential that I
found best at high and low rate.
High rate exponential Low rate exponential
Elev. 80%* 45%*
Rudder 45%* 15% *
Ail. 70%* 65% *
*I have not put any symbols (+ or-) because depending on the radio brand that you fly
this symbol can have a different meaning. The type of exponential that I am suggestion to
you is the one that reduces the sensitive feeling around neutral stick position, in other
words makes softer feeling to the airplane.
Mixing
The 102” Yak 54 requires none or very little mixing. I am using on mine 2% mixing
rudder to aileron to stop the adverse roll coupling. This percentage is very low and
probably you’ll not see till you make a very long knife edge flight. The other mixing is
rudder to elevator in order to keep the airplane tracking perfectly straight at knife edge
position, without going to the belly or canopy at that position. The mixing is very small
too. If you have mixing curve in your transmitter it is what I am using to fine tune the
airplane along all the rudder stick deflection. Under this type of mixing I am running
from neutral up to 33% right rudder stick deflection 1% up elev. mixing, from 33% stick
deflection to 75% stick deflection 3% up elevator mixing and from 75% to full stick
deflection 4% of up elevator mixing. On left rudder I am running from neutral to 33%
stick deflection 1% up elevator mixing and from 33% stick deflection to 75% stick
