View Full Version : Need smaller diameter motor shaft...

Have just ordered a Hextronics HXT 80-100 motor to use with a scale Soloprops 4-bladed prop on my Giant Scale Mustang. After ordering I found out that Soloprops hub only take 8 or 10mm shafts and the HXT have a 12mm shaft. Have been recommended to machine down the existing shaft and re-thread. I'm all new to electric flight but understand that it can be a little bit tricky to remove the shaft from the motor. As the shaft of the HXT is running through the motor, would it be possible to, without damaging the motor, fit one end in a lathe and spin it still attached to the motor? Might be a stupid question, but... I'm a novice to electrics... ????

Grateful for help

Benny

Hi TS,

I definitely advise AGAINST putting it to the lathe while the shaft is still attached to the motor. The first reason that jumps out at me is debris getting into the motor itself. Those are some pretty strong magnets inside that body. I think it would be extremely difficult to do this without getting metal filings in your motor.
Secondly, if you do it and mess up the shaft it will cost a fraction of the original price to replace. If you mess up the motor during the process, you pretty much have to buy another one.

Just my humble opinion.

Is there another prop manufacturer that could satisfy your requirements?

I bet it is possible to order another shaft which is suitable. They are usually not very hard to replace. I've seen several different configurations of motors, those which have one fixed diameter on the shaft going through the motor assambly, and a variaty of diameters on the extension where the pinion, or other options are suppose to be mounted.

Well, there is more in Norway...

www.radiostyrt.no (http://www.radiostyrt.no) is a really great site for those understanding norwegian. I am a member there too.

Wattflyer.com is just a way to extend my horizon. Several members with good knowledge. My neighbourhood is just not enough, so to speak.. besides, wattflyer.com is a pure electric (no gasoline) forum - which for me is very good.

Hi guys.

Thank you for your input to my problem. I think I have a few ideas to look at a little closer now... and, yes, I am indeed Swedish! My user name is not an expression of vegetable fanaticism... lol. I am from Gothenburg (Göteborg) but living in Suffolk, England since 4 years. Great to "see" fellow scandinavians here too! Thanks also Ron for your concern and tip to visit the swedish web site although, as Vidar says, I think that Wattflyer covers most I'm intersted in at the moment. Have gone from being a glow and petrol-head to electric fan in the last couple of months.
Keep posting and again, thanks!
