I have taken elevator pushrod force = measurements=20 and was surprised.
Elevator pushrod forces to stick forces = are about=20 6.5 to 1
The trim system, when dialed in, = provides these=20 forces.
 
At 190 imph and -7=BA flaps, there = is a 60lb=20 forward force.
At 80 imph and 10=BA flaps, there is = about zero=20 force.
At 80 imph and 20=BA flaps, there is a = slight=20 (-1lb) rearward force.
 
These numbers are with the horizontal = stabilizer=20 built at -1.2=BA
- - - plans range is -0.5=BA to = -1.0=BA
 
An input from the flap bellcrank = of about=20 20-40 lb at -7=BA would be good,
 tapering down to zero lbs at = 10=BA=20 flaps
 
A horizontal stabilizer built at = -0.5=BA would, of=20 course, change these numbers.
 
Comments ?
