View Full Version : MJmod has rattle noise

02/01/2007, 09:54 PM
I built 2 1200MJ mods.

1 is perfect.

The second has a rattle vibration issue.

Any suggestions on what this could be?

I did buy the "better" shafts from the site.

uneven weight distribution in the prop? most likely the cause

i just built 3 from mj mods last night 2 mj 900 med flow they work great so far no noise at all,and one 1200 using extra parts and the bigger prop that makes some noise the hole in that prop is bigger than the octura if you glue it when its off axis it will make noise. try to see if it runs on an angle. good luck:D

I pulled it out of the tank today.
If I hold the ends and spin the center, it seems like the magnet itself is not centered.
Maybe the prop also... not sure.

Whats the fix for this?

the glue doesnt hold so great on the prop see if you can break the bond if you didnt use too much glue yo umight be able to.
