Electric, thrust washer, spinner and prop mounting?
« on: December 09, 2013, 03:17:36 PM »
I couldn't find a great deal on this subject.

Motor shafts look shiny and smooth and absent of parts needed to mount spinners and props. I don't see threads either?

I'd like to learn about mounting methods of what parts onto the motor shaft?

Also, reversing the shaft for front mounting?

Any information, especially if accompanied with photos will me much appreciated.

Thanks in advance.

Check  List your set up.   there are lots of threads on mounts for prop. Bob Hunt & Ptg's were some.

Hi Charles,
Like Bob said, the collet holds beautifully, but do remember to clean the shaft and inside of the collet with acetone or lacquer thinner to remove any machining or storage lubricant, and periodically check the propnut tightness. They work fine on the 3 kilo-Watt Pattern setups on 8 mm shafts!

Dean,

8mm, that's a lot of shaft and is probably overkill for the model I have in mind and for my first electric model.

Most of the motors I've researched have 5mm shafts.

The model I'll build for electric has only 543 sq's, 55" in span.

Thanks for the reply.

Hi Charles,
At the roughly 400 Watts your Stunter will run, a 5 mm shaft is plenty. 6 mm would be nice for vibration and longevity but just add weight. The F3A stuff runs 3000 Watts! 8mm is actually necessary for them.
