Default RE: flapperons on cub

Will help with what? You say it comes off the water "pretty good", do you want it to come off the water better?

If so, try this:

First, put a level on top of the floats and block them up so they are level (Or use an incidence meter to check this)

Once they are level, put an incidence meter on the wing. You should show 1.5 - 2 degrees positive incidence (that is, the leading edge should be higher than the trailing edge)

If you have less than that, shim the float mounts to get the proper incidence.

If the incidence is good, shorten the aileron pushrods by about 2 full turns each. This will drop both ailerons just a little which will provide extra lift.
