Yeah, I might have to try that. Just not as confident or skilled as you, Steve (I can already see some little part flying across the floor somewhere, never to be found again...). On a positive note, I nailed the spinner gap

He removes the rear can of the motor and uss and aluminum adapter for a fiberglass x mount. I believe this mod also helps keep a cool motor cooler.

The weight difference isn't that much, 10 grams or so. The main benefit is that the mounting holes of the motor will line up with the factory blind nuts and make it easier to mount with the lightened version. I've had both and used them on slicks. Either one work fine.

Ken doesn't recommend against removing this, he recommends against removing the motor mount/backplate. Removing the can is super simple. Just remove the collar from the shaft on the back and the can slides right off. It is the easiest way to mount this motor.

I think you have that backwards for the 3615, the backplate doesn't even come attached. Some of his larger motors he doesn't recommend removing the back plate on. If you have good Allen drivers removing the can is easiest, but running the screws backwards through the blind nuts and using lock nuts on the mounting plate works fine too. I don't remember if the slick kit came with spacers or not but you really only need them big enough to run the motor wires out the bottom without them scrubbing.

The ones that come with the plane work fine for the Motrolfly or the Hacker. They are 1/4" long.

So I painstakingly used needle nose pliers to slooooowly tighten each bolt gripping the outside.....and of course now I want to rotate the motor so the wires fall better for my ESC install. Just not comfortable removing the can, esp if Ken recommends avoiding that. Wish I just did what Johnnyrocco did and bolted from the other side (didn't have right size nuts on hand and got lazy). Was hoping to maiden this weekend but delayed b/c one of my 5085's isn't centering properly so have to send it back, so I'll use the extra time to get the wiring exactly how I want it. I CAN'T wait until spring to fly this machine, and I'm in Chicago so it may be a chilly maiden...
I used a Duratrax ball end driver to mount the Motrofly. Its a hobby brand tool, I think I got it at RC Planet. It will easily go to a 45 degree angle.
