Using the Botosizer to size the ball links makes this job of sizing your links very easy. This additional tip aids in obtaining the perfect link sizing without having to pop links on and off the swash, head, etc..
Here I used a Synergy E7 frame spacer with a regular swash ball screwed into the end. I then chuck it up into a hand drill to make it easier to handle. This allows easy sizing of the ball links with the Botosizer off of the heli which to me is a plus.
