Pulled the Zelos 36 down off the shelf to start getting it ready for the Nationals, coming up this August.
At the 2-Lap in March, I ran it with these huge 40mm Voracity motors and found a couple of things that needed attention.
1) The motor mounts would "shift" in a hard flip.
2) The stub-shafts were too short to fit the new generation of ABC Props.
Figured I'd document my attempts to fix both issues.
First, the motor mounts.
The black base material that holds the captured motor mount nuts is made of a polymer. As such, it's pretty slippery. Snugging down a piece of shiny, anodized aluminum doesn't provide an interface that promotes holding the motor mount location once a 350g+ sized motor is attached.
The REAL solution would be to install a fully supported front/rear motor mount. However, being lazy, and not wanting to battle getting a motor in/out something like that, I thought I'd try a "quick-fix" first to see if that would work for now.
I milled the motor mount a tad to create some serrations that will hopefully provide some "bite" into the base material.

I then cleaned the base material really well with some Lacquer Thinner, and applied some of the thin aluminum adhesive backed duct sealing material, commonly used on dryer vents, etc. Has a very sticky and thin adhesive on one side, and soft aluminum on the other. I'm hoping that the adhesive doesn't get "slippery", and that the serrations help it all to "bite" into the base material enough to hold everything in place.

Finally, I installed some larger diameter washers to help spread the load a little more when I tighten this thing down.

Not sure all this is actually going to work, but figured it wouldn't hurt to try. If not, I'll move onto phase 2... more suitable large-motor mounts.
