I've had my 1524 for several months, so it was ordered some time ago. I ordered a finned can and that's what I got. I just wasn't told that the motor was mostly developed for air or marine use so they didn't have any 1524 size finned cans. So I ended up with a 1527 size can on a 1524 motor.
They might have the right cans made for it now??? Or if you get a smooth can.....
Sorry, can't help on whether it fit's the losi.
