Flying a 74" EF Slick, electric power. Notice a fairly heavy right wing drop when doing a waterfall. Also effects other maneuvers and I need a decent amount of correction consistently. Lateral balance is good, CG is spot on, elevator throw is equal on both sides.
What could be causing this?? I'm stumped.

Thanks

could have a warped wing.....you say you did a lateral....did you use the shaft on the motor if you did it has a thrust off the fire wall and that can really throw you off.........

I believe in dynamic balancing, do a few parachutes and see if it drops the same wing consistently. If it does then add weight to the opposite one.
Make sure you pull only elevator without messing with ailerons. You may assign full up elevator to a switch just for the tests to make sure you isolate this input.

agree with all but i had a bad tendency to mix rudder with throttle (human error) and she would act as you are describing

Left rudder is required when you push, right rudder when you pull. Happens all the time. Some aerodynamic voodoo causes it. Maybe gyroscopic precession from the prop as the plane pitches. Or p-factor?

Wow, lots of insightful info. Thanks guys.

When you say you did the lateral balance, did you do it on the bench or in the air. I would suggest the trim chart earlier posted. It takes a bit to go through it all, but it makes a huge difference. And my Slick needed very little adjustment really. EF is so well built.
