PF XL v ev3 M

[SNIPE]

Hi,

I'm thinking about powering my latest 42029 mod, it is currently using 1 PF L motor, however the rotation is jerky and it is struggling a little

which wears the batteries down so -

Should I use a PF XL motor, or a torquier and slim EV3 motor?

It needs to drive a gearbox which has a lot of gears plus a white clutch gear (5 speeds or more), and the winch and loading bed and the functions gearbox.

An external return to center mechanism ,small as it can be is still probably too big so I'm using a PF servo motor for the steering, all motors are then connected to a normal 8881 PF battery box.

So any ideas?

I'm not sure if you should use a clutch in the drive

its the only way to have a compact 5/6+ speed gearbox using normal clutch rings.

it acts like an idler in some speeds and like a normal gear in other speeds which lets me combine speeds to get more speeds!

if that makes sense. For example I could add 1st gear and 3rd gear to get compound train output.

Normally the gearbox would just jam but the clutch gear allows it to work. The transmission is 3x5x7 in dimension.

i'm using a weak clutch gear, but all 3 strengths still work.

I suppose you could cut off the back of the 24 tooth differential if you're not a purist?

That wont work it needs to be a normal gear unless theres another gear something driving it then it becomes an idler gear.

What motor should I use??
