I know the subject is a little vague.
I just picked up a cub in a trade, and although it's obvious it's a kit build, I have no idea on what throws should be on the control surfaces.
Is there any information I can provide that will give some guestimate on the throws? If not the backup plan is to use max throws with 60% expo.
You can download manuals of a comparable scale plane as use that as your starting point
the Great Planes 40 size Cub recommends
These are the recommended control surface throws
(NOTE: Throws are measured at the widest part of the
elevator and rudder.):
High Rate Low Rate
ELEVATOR: 1-1/8" [29mm] up 5/8" [16mm] up
1-1/8" [29mm] down 5/8" [16mm] down
RUDDER: 1-3/8" [35mm] right 1" [25mm] right
1-3/8" [35mm] left 1" [25mm] left
AILERONS: 3/4" [19mm] up 1/2" [13mm] up
11/16" [17mm] down 7/16" [11mm] down
*NOTE: These control surface “throws” are
approximate and provide a good starting point for the
first flights with your Piper Cub. You may wish to
change the throws slightly to provide the smoothness
or quickness that you prefer. Increased elevator throw
may be required for spins and snap rolls.
