Ducted Fan RotorOk, I dont' know the brand of this rotor. It came to me in a deal with a Rossi 90. I'm not the expert on this kind of RC power system so be sure to be the judge yourself. This part appears to be new and unused other than some dust from being in a parts bin. There are no nicks or scratches in the blades. I do see witness marks from mounting that I presume is from balancing. There are no marks on it from an engine backplate. It's my opinion that it's new-unused, never mounted to an engine. You decide for yourself and I won't be unhappy either way. ;-) It's hard to measure the OD of this rotor because it's 9 blades. I believe it to be 142mm (5.59"). Thickness is 18.67mm (.735"). Blades are imprinted "TORNADO 9-3". It appears to have been manufactured from glass filled nylon aircraft prop blades which I believe to have been popular back in the day.
