It's more than the same - it's *drastically* cool.
And so the obvious occurs to me... Have any of you folks with the retractables put a servo on a dial control to make an arm wave?
I think that with arms extended evenly, that one arm moving further forward should cause that side to pitch up, causing roll and possibly yaw. And opposite behavior as it moves backwards.
Perhaps a mix from the dial to the 'footievons' (that's what they're called, right? LOL!) to minimise the pitch/roll/yaw effects and maintain straight/level flight.
