Here's a link to the I4C Isolator: http://www.i4cproducts.com/the_isolator.htm

It may eventually turn out to be the servos, but I'm still in the elimination phase with other components. What do you do with 9 basically new 90 dollar servos? If I send them in to be checked, they get replaced with new ones for an additional 20 bucks each ($180.00??), and I won't even know if the old ones were defective. That's not what I'm planning on doing. I'm simply not going to spend like a rich guy just to keep a 31% plane.

This FM receiver is the 3rd one in the plane. I don't think it's the problem.

Had to work today and couldn't get out to fly it.
