Front mount/ Rear Mount?
« on: December 27, 2018, 04:57:52 PM »
My planes are all 58-60" wingspan size.  I'm using either the Hacker or AXI motors of the proper size.  Both are shipped for "rear mount".  In order to configure for "front mount" it is necessary to dismantle the motor and turn the shaft around.  I do not want to do any mechanical "magic" on motors. 

Some have cautioned that rear mount places undue stress on the motor.  My firewall mounts are very solid, and my "rear mount" motors have shown no wear or other problems.

So if rear mounting causes no problems, why should I think about changing?

If it ain't broke don't fix it!   y1

I should have done a search first.  Now that I've read several opinions regarding front/rear mounting, I see that the opinions are about equally divided.  Some say that rear mounting stresses the ball bearings.  Maybe so, but ball bearings will take a lot of side loading, which is the mode associated with flying sharp corners.

So maybe my motors will only last for 200 flights instead of 300.  It would take me many years to get that many flights on electric, since I also spend a  lot of hours flying with  glo engines, and spark ignition.
