Balancer Tools for Self Tightening Propeller (using Unused Tamiya Rollers)

I wonder, how many of u ever playing a tamiya... and how many unused spare part of it left behind... i just found my tamiya bumper roller and i tough i could make it for a balancer tools for self tightening propeller such a DJI 9450 prop or else... i need this balancing tools to reduce jello effect on my Quadcopter and basically it work like a dubro balancer...

what u need is:

4 x tamiya roller like http://www.tamiya.com/english/products/94739rolle...

and 4 x sort 4mm diameter screw...

Take out your tamiya roller from bumper...

try spin the roller, if it not smooth than don't use it...

download 3D files from

and print it.... i use 40% infill for it, that's enough for it...

Put the roller to the roller holder.. like picture above...

PS: u need two of this

Put the roller holder to the balancer stand, the one of roller holder in the back is upside down (the hole is below the roller)

Put the rod in the hole and put the propeller on it... one side of the rod is CW and the other side is CCW

PS:Sand paper the surface of the rod which contact to the roller, more smooth are more better.

or u can use any other cylinder tube to replace the rod...

Try to move the propeller lightly CW & CCW, if the propeller is falling down than using sand paper try to reduce weight from the falling propeller leaf. than try to lightly move CW & CCW again.

if the propeller is steady or nearly steady enough in the middle than it balance...
