Any Hudy tool I've used was always top notch. If you want another alternative, you can easily modify a Dubro prop balancer to accept Monster Truck wheels. Even the 40 series. All you need is a slightly wider base plate. Here's a couple pics of mine.

I made a wider base plate out of a thick sheet of aluminum so that the Dubro prop balancer could be used to balance my Monster Truck wheels. The balancer is now wide enough so that it can accommodate 40 series wheels. To the left is the original base of the Dubro prop balancer that I used as a template to make the holes in the new base plate.

This is the shaft of the Dubro prop balancer. It comes with two cone shaped aluminum pieces that I use to secure and center the wheel. I also use an old Maximizer 17 mm hub (the black piece), a spacer which is just a plastic tube to center the wheel on the shaft and a collet to hold everything firmly on the shaft.
