When you balance a plane like the 4*, do you do it upside down by the prop shaft and tail gear? When balanced level, if a wing is touched should it drop, no matter which side? I think I have mine balance correctly, when done, both weighed the same and it stayed level unless I breathed on a wing, then it would roll to the side I breathed on. This is a big MF to hang from a string, I put a hook in the ceiling to do it.
