Recommendation for 600 helicopter motor with 5mm shaft ?
As I am having a lot of troubles getting a 6mm straight cut pinion gear , I thought might try to get a 5mm shaft motor instead for an old HK600GT .Now the problem is no one manufactures 5mm shaft motors anymore for 600 sized helis!! Can someone point to such a motor that can still be bought new? I am not after massive power/ quality?
Thanks again

For this hk600, you can look for a 550 motor, 5 mm shaft.

Check this...

The original motor is 1100 kV witn 6 mm shaft, so no big difference.

As you can see, this solution is quite expensive.

Thanks Rojo. I'll have a look at the motor dimensions.So this motor is sure to have enough power for my HK600GT,as the dimensions of the can are smaller.

Why dont you just have the end of the shaft on your motor turned down to 5mm. Maybe there is a shaft that will fit that already has a 5mm end on it.

Well, as we said in another post, it is much easier to get 5 mm shaft diameter pinion, drill a 6 mm bigger hole and that is it.

Don't losse your time trying to get a 5 mm shaft for this old HK motor.
