RE: Nitro Planes Hero 100 Version 2
Mark,
Here are some photos of the RC Lander 90mm DF using the Wemotec Midi Pro rotor and spinner. The 6-blade Midi Pro rotor is on the left and then mounted in the fan.
The shaft size and adapter screw are the same so it fits right on the Lander adapter. The Midi Pro rotor length is slightly smaller than the Lander rotor length by about 4mm.
So it still looks promising for a reasonable load on 8s with the Neu motor. If not, then the Midi Pros will provide a known 2500 watts per side with great efficiency.
