[NSRCA-discussion] Motor Mount

[George W.Kennie]

Hi John,

Sorry to have to tell you that I received no replies to my inquiry.

I have the feeling that most people are just not addressing this issue.

It would make a great product for somebody like Jerry or Chris to produce.All that would be required is 
an X brace with an oversize receptacle at center to receive plastic inserts (like props) sized to fit shaft
bearings.

Georgie

  FWIW:
  I am interested in an answer to your question too! It sure looks to me like some kind of nose bearing would be prudent...

    Hey Guys,

    I have a new project in the works and it involves mounting a 2K watt motor. This will be my first larger motor install so I felt that some advice from the Pros
    would probably be appropriate.

    The Motor is an outrunner and I can mount it from the back side directly to the firewall OR I can use standoffs and mount it from the front side of the motor.
    I keep feeling that there needs to be some kind of a stabilizing bearing on the free end as there portends to be a significant amount of rotating mass if I just 
    bolt the thing to the firewall while a pound of motor whirls around with a large prop exerting inertial rotating energy beyond the front of the cowl. It seems like 
    If I use the stand-offs, there will be a more rigid area between the prop and the motor, but then I worry about the back end. Should I figure out some kind of a 
    bearing mount on the firewall?

    Somebody set me straight on the accepted procedure please. 

    Thanks for you help,

    Georgie
