Hi all. I have a brand x 3 ch heli that has no apparent source for parts. I am looking for an equivlent helipcopter for whcih parts are available. The heli is about 16 incheas long. The cheap plastic head on the inner shaft broke after a couple of uses. I have been looking at walkera, syma, esky, etc to find something usable. It seems close to an Esky Lama 4 but I understand the Lama 4 inner shaft is too short . I need at least 129mm of shaft below the head. Can someone hlep? Noone seems to post parts dimensions. I looked at Xtreme Productions for example and can't tell how long their shafts are. Shaft diameter is 2mm.
