NX7 kit fit a 9.5MM size crankshaft engine? Anyone know if the NX7 Kit will fit an engine with a 9.5MM crankshaft? I could not find the innner diameter of the fan/clutch assembly in the manual to see if it would bolt up to an engine with a 9.5MM crankshaft. Thanks in advnance. |

/Wait a minute!This kit is not from Mars!This kit is a class 90 helicopter.The fan should be for class 90 motor shaft, that is 3/8" shaft diameter or metric equivalent. (9.525 mm)If for some reason, the fan has a bigger hole, that kit must supply the conical brass adaptor.For example, when "miniature aircraft" put their fan with bigger hole for tempest and stratus kits, they run the #0546-6 part to fit the crankshaft to the fan.So, no surprises with this new kit.../ |

/Now I understand what your point is.The Instruction manual said nothing about motor size!!!It is not obvious, BTW.According to helicopter size, we see that is a 700 series, 91 class. Instruction manual said nothing about it. No warnings... Nothing.I can think about install a Os55hz, 50 class, but it doesn't fit on motor base..!NX7... So, the seven, 7, said everything?.../ |

/Big problem!When someone said compability with 90 class motor, I know for sure is for motors with 3/8" or 9.525 mm diameter shaft. That is the standard!So, 8 mm diameter motor shaft is not an standard in 90 class helicopter. Probably your are talking about an airplane standard.Let us know about this "special" 8 mm shaft diameter motor./ |

/Advertising very convenient!So, they suggest to modify the fan HUB to assembly correctly this motor. That is Depend upon the HUB, of course.Probably you will need to tight the bolt a little bit more or maybe to run a brass bushing in between.Bad... Very bad./ |
