The Ultimate P3 Prop Balancer

I have been balancing props for decades on RC planes and find the Top Flight balancer to be the very best. I wish I had seen the "Ultimate Prop Balancer" solution before I came up with my ultra low cost one pictured here. The wood is from a Home Depot 5gal paint stir stick +a couple of single edged razor blades and a DuBro shaft. Works very well and almost no friction...

I balance the blades in two ways on my bigger props: (horizontal balance) and the hub "front to back" balance (vertical balance). On small props like the P3's I just go for side to side.
 
I've always strived to balance horizontal because that tells me each side is the same weight.....meaning balanced.
Maybe someone else will chime in.
When you balance horizontally it balances the blades, then you do it vertically to balance the hub.
