I just received my Hacker A60-L16.

How have you guys mounted your motors ?
Front or rear mount ?

Could you guys post some pics of your mounting set ups ?

Thanks

Hacker makes a mount specifically for it...you sort of need it, or something that works exactly like it. It mounts the motor into a cradle and supports it at both ends.

Mithrandir · 10-20-2009, 12:05 PM

the gyroscopic precession generated by the prop and motor combined mandate a front and rear motor support.....

this motor is a lot of power!!!

Contact the folks at Hacker Brushless USA... they will help you!

The "Mad-Dog" mount is a good option...

Eric on RC Groups makes them, his user name is mad-dog

Thanks Guys,
I got it now. I can see where trying to mount it like a normal outrunner in front of the mount would have too much side load on the motor.
I just spoke with HackerUSA and they told me who to call here in Canada to get the mount for it.

Ordered the Hacker A60-MM mount

. Hopefully it will be here next week.
Man this motor is big

Mithy, maybe the neurons in my brain aren't connecting properly (again), but how do you support both ends of an outrunner motor???

bodywerks · 10-20-2009, 05:32 PM

Nevermind...I see that you need a bearing and shaft at one end.

I had the Hacker mount and it is a great design but in my opinion poorly executed. The way it is bent, the metal is fatuiged from the get go and mine failed at that point. However I did use standoffs to space mine correctly, so if you do use the Hacker mount, make sure to mount it directly to the firewall and DO not use standoffs.
In my opinion the "maddog" mounts by Kevin are by far a more solid and reliable mounting solution. Again this is my experience and my opinion, but I can guarantee I don't worrie about mine anymore.

the big Hacker Outrunners have about .5" of shaft sticking out the back side of the can.... for bearing engagement

Mithrandir · 10-20-2009, 06:19 PM

the mad dog mounts may work... but technically, a horribly un-optimized design!

How is the torque from the motor reacted???
It is reacted at the base of each standoff....
if the bolts loosen even a tiny bit, or the wood compresses... it get dangerously sloppy.....

if the standoffs were replaced with a box... that would be better...well... less bad....
the standoffs around the motor do not efficiently react the torque.....

the design may work, but if one of my engineers handed me a drawing of this... he wouldn't be getting a Christmas Bonus!!

just sayin'

3DHobbyShop · 10-20-2009, 07:06 PM

Yes, a fabricated box, that'll be easy to build for $60. I recommend you lead the way.

Simpleton · 10-20-2009, 07:28 PM

I can't see how it's any different than having stand offs on a gasser, and practially all rear mount gassers use stand offs.

3DHobbyShop · 10-20-2009, 07:39 PM

Well, better throw the standoffs away and build a box...

if the engine box itself is spaced out properly, no standoffs needed....

in the case of an outrunner such as the Hacker A60, a simple molded composite engine mount would not be that difficult... two molded parts...or one molded part and one turned part with a bearing... and a few screws....

If the standoffs had a 45 degree element... they would be much better....
