I would like to write a post about how to assemble Hobbyking Magnetic Prop Balancer device. It might look easy on the picture, but when you get to it you might find this helpful. Since no instruction manual is shipped, like in case of an IKEA furniture you need good assembly skills.

You will need to align the two sheets that have trapezoid shape and connect them with the U-shaped ones. Something like this.

For assembly you will need to slide the metal inserts and bolt them on with the small diameter screws. Please observe that only one side of the inserts is threaded, so you need to insert the screw from the mating side. This way you will have clamping force.

Then you will need to do so on the other side as well. You might need to peel off the protective paper layer. Depends on how tight the metal inserts are.

After this you can insert the big metal cup on one side. Secure it with the larger diameter screws.

One side is open, the other side is like a sunken cup. Into the open one you can insert the matching big cup. It is threaded, allows adjustment.

With the threaded cup:

Then comes assembly of panels.

Now comes the difficult part. You have to tear apart the 2 magnets. They are really strong. Do it carefully. When they are apart you can insert them into the cup features on both sides.

Between the two magnets should the axle float. The axle is pointy at the ends, so friction will be minimal.

Onto the axle you can slide the 2 conical rubber features. This will support the prop.

If I am right the rubber O-ring can sit on the adjustable side of the balancer.

When ready it looks like this.

A short video of how it does work.
