The 4985 1650 motor is rated for 6s use maximum, the 1100 and 800kv motors are rated for 8s but then you’re moving to a larger 56mm can. What ESC are you using? That would have to be rated for 8s as well, of course. I believe the 4985 would run crazy fast on 8s just before it fries.

If you replace the HW 4985 bearings with better quality ceramic ones it will survive 8s.
Been running one on nothing but 8s for 2-1/2 years now and never a single issue.

You ever been out bashing and have the throttle pinned wide open and thought, “ I wish I had just a little more”? That’s what I built this for.
I’ve only ever hit full throttle once and it completely shredded 3 out of 4 backflip LPs
I used this on mine: https://www.powerhobby.com/phmount03.html

The mount will accept 2x30mm or 2x40mm fans, I went with 40mm. I had time to wait when I ordered the stuff or I would have gotten the surpass-usa 40mm fans to get them more quickly. Pretty sure I ordered a couple extra fans just in case as I never tried this particular fan before. They push quite a bit of air when running on 7.2V off the max6. I got a couple of the 30mm fans to of the same brand to have on hand.
I'm only intending on running 6S with mine. Hoping it allows me to gear up a bit more than the 4092/1650kv. I ran 19T pinion on the kraton with it, but installed a 21T with teh 4985.
I'll look into those bearings. I replaced the ones in my 4092's and blx4074 motors with ceramic hybrid TRB bearings. Will see what I can find for 6x19x6. I'm assuming it uses 2 of those, same size on each end, right?
