well acctually, vario makes some padeless heads for scale use. they would acctually simplify the PC links of the head because there are no mixing arms exc. for the padles/blades....just 2 rods going strait up from the swash plate to the blade grips. as i said before they are meant for scale use so they they might not provide the profomance needed, but then again, we're only tryin to hover here
