I have seen about a year ago, how one guy had installed blade grips with the control arms on the same side of the head. He had asked me to check his heli setup and yes, was weird how he even got it assembled the way it was but I strip everything and rebuilt heli from scratch for him. The blade grips for the old and new Raptors are different, not just a replacement part of the older ones which means you'll have to replace both grips with either the older or newer grips. Will measure and check them tonight, but I'm almost sure the control arms are longer and the grip itself is longer. Regards, Gavin
