Push the Boto sizer into the link without twisting.  Turn two complete turns remove Boto sizer from link without twisting.  Check link for binding, repeat if necessary using only one turn for each additional sizing.

The boto sizer works very well. Be careful because it will remove material very quickly. Make sure you back the screw off before you start. I would also have some spare links available. They are a handy tool to have.

Good catch Scotty, I forgot about the spacing / sizing screw.  One other thing, use a Q-Tip or something similar to remove the cuttings from the inside of the link after each sizing and before testing for fitment.

Sorry, back what screw off?  And spacing sizing tool?  By two turns, do you mean two complete 369 degree each turns or just two twists if the wrist?  I'm still a little ways from that. I just have to work on the one way bearing and main gear along with the motor today. Maybe tail boom, we shall see.

There is a small Phillips head screw in the tip of the tool. Tightening that screw forces the cutters open more thus making the hole in the link larger.  Be careful with that screw, it doesn't take much to over cut a link.

by 2 turns he means, 2 complete rotations of the cutter.  You want to take a little off at a time and check between attempts. You want the link to pop on firmly. It should have little friction once installed but not have any slop. If you are getting slop once popped on the ball, you cut it too much.

You will mess up a couple at first, just part of learning. The kit came with 1 extra. Go slow and check twice.

Once you get the technique figured out, it's a piece of cake.

So is it for enlarging smaller links or tuning the links in the synergy kits for a proper fit?

Tuning the links for proper fit.

The Boto Sizer comes with 3 sizes cutters. One for Synergy links, one for standard links, and a small one for small heli links.

I'll be careful, hopefully I will get lucky and not mess up any of them.

Of the topic question:  Is it ok to assemble the CF servo arms before connecting to electronics?  I know I will have to take off the wheel when I begin leveling the swash, but just want to make sure it isn't something permanent.  Which it can't be because things must be removed from time to time.  But just double checking.  I ask twice cut once as well.  ;)

I would center the servos first. The splines on the servo wheel will vary but normally you have one spot on the wheel that will get you fairly close to perfectly square without adding trim.  Once you find that spot on the servo, you will be able to attach the CF arm and know you are almost if not right on mechanically centered.

Are many ways to center servos off the heli. I like to plug everything into the FBL unit and bind up the TX on the bench before mounting any electronics.  This is the way I showed in the video. This way I have my servos center and arms built off the heli. A lot easier that way in my opinion.  On the E5/6 the elevator servo is easy enough to get to, but on the E7 moving the servo wheel is a bit more complicated once the servo is mounted to the heli.

Yeah I noticed on this heli it will be pretty easy to adjust the servos horns.  I won't have things soldered until tomorrow.  So I'll do everything else but that and just wait.

Just got my Boto-sizer in and looking it over. Does it cut/shave or just expand?
Seems like there are burs on it from the slot cutting do those need to be cleaned off?

Thanks Barry

The edges should be clean of any burrs. Then when you're ready to size back out the screw all the way, insert the sizer just like a normal ball and make two full turns. That should put you right where you need to be size wise.

Drat oversized my ball ends on a couple links. Takes a little finless to get it just right.

For sure. Better to go slow and make small changes. I still over size one in 5.
