Which motors do you use in the same manner which are surviving better?

turnigy sk3 there senorless but pretty bomb proof
Weird. I’ve had the opposite with them. And weak as piss.

i’ve cooked the stator of one from a rc esc failing and broke a shaft on another from a mount loosening.
what bust on yours?
I found them to be way underpowered and heated up unacceptably off-road.
Are you saying you did 6000 miles in a year in the wet on the Apex/flipsky motors?
i have noticed this a little. but jens noted this on the other forum with his leopard motors. as for heat i haven’t found much difference in outrunners.
~4500 miles due to board down time and riding another when the ice and snow hit (about half and half wet and dry)
I can’t imagine any motors were using to last that long without any bearing maintenance

i believe it may have been a bad bearing as there would be a frequency at about 10-15mph (same speed the bearing collapsed). my wheel bearings on the same board haven’t needed replacing/ running as close to new

This is for @Shadowfax
I machined down and hardened some 12tooth mod 1.5 gears to use on my sk3
Now running
190kv 1:4.89 mod2 and
192kv 1:4.91 mod 1.5
This is what a steel to pom gear looks like after ~4500mile greased riding

This is awesome. It doesnt look like there is a key in there. Did you run just a set screw and it held for 4,500 miles?

I’m surprised this isn’t happening more often. To me, the 8mm and 10mm is a leftover from the skateboards from the 1980s… I’m using 16mm axles but it requires custom wheels to house the larger bearings. But if you can CNC aluminum you can go with all sorts of larger axle options.
the 4500 miles were done on a keyed pinion.
i did 40 miles on a pinion held solely on 638 bondloc
and the mod 1.5 gears are just running a set screw and 638

sooo, moon drive board is out of action awaiting on some gears to run big motors, very excited.
but i contacted mr @Archer and he very kindly sent his v1 to “test”
they arrived last week and i promptly set about modifying and installing them.
retapped the hanger clamps to m6 instead of m5 and press them on the hangers as matrix 2 tolerance are all over the place.
machined new press fit adapters. modified motors to fit and machined spacers for the helical gears
pics-
the controller immediately disconnected, full throttled and ripped the newbee escbox off
the drive is quiet af and has enough torque to rip your ass off, there is a place called great hill near me only 1200ft elevation but the rocks are nuts. small video of a small part of the water section of the ride.

wasn’t in a great mood, went out for a rather nice night ride. i couldn’t quite make a corner and nailed a lampost, full 180 around it from the speed and totaled my front baseplate

@longhairedboy how does he not have a title yet? I feel like him staring at things already breaks them.

switched front truck to matrix 3, they feel sooo good. but i like to run matrix 2s stupid loose
(front bushes don’t touch the base plate when not turning) tarmac powersliding in tesco car park led to me busting the side of a trampa hub out

the key desired freedom and sawed an escape hole.
@ApexBoards love your mounts but i had to commit some heresy
yes that is a drill press and a carbide burr
@Andy87 if you revisit inrunners, matrix 3s fit sss56123 nicely and they take off real good @200a per side

what exactly am i looking at here lol? Are you saying the key on the motor’s pinion slid out the end of the keyseat and bored a hole through the casing of the gear drive?
exactly that lol. i pulled into work and the breaks weren’t great. checked it to find a hole and the key missing
