Standard accessory pack for NTM Prop Drive 42 series motors. CNC Machined (take a close look at the cross mount, even that is machined rather than punched) from billet 6061 alloy for strength and balance.
Produced in-house by hexTronik to reduce costs and deliver better value to you!
Thanks for suggestions on fixing the prop hole size problem.
Another problem I am facing is that the crossmount fits well on the motor, but the outer holes on it do not align with the Great planes motor mount. I assume GP makes standard motor mounts. I got a wooden one with my ARF plane
Most of the times, at least in my cases, holes on crossmount and motor mount never align like it should, becouse motor mount has usually holes drilled for specific motor.
The way I fixed this is, if the holes are way off like they should be, I just drilled new holes, and mount the motor, bit if the holes are just a little off, than I filled the holes with epoxi, and drilled new holes.
You can use old holes for motor aligning.
most props come with a small centre and adaptors, best if the centre is as close to the shaft size as possible and centre accurat. I have found using a step drill the eaisest and best way, it will keep the centre where it should, I used to use a normal drill but it often went out of centre and off balance. a step drill starts a small size and "steps" up in size, I got one at low cost from a tool supply shop, maybe hobbyking could stock them very useful for props and spinners or anything else needing an accuaete round hole. cheers hope this helps.
Can anybody suggest a suitable 50mm alloy spinner for this shaft. It's big at 8mm and spinners that require a collet don't appear to go up to this size. If M8 nut fits which I can buy, again which spinner, is their one that will fit it OK. ?????
i used that at my Katana
Aluminium Prop Spinner 51mm / 2.00 inches / 2 Blade with Brass Nut for Spinners M8x1-M3.
prop with how many blades?
Aluminium Prop Spinner 51mm / 2.00 inches / 4 Blade
Aluminum Spinner 51mm / 1.25in - 3 Blade
if you have a drill stand, you can also directly threading into the shaft
