Do you know what sort of Torque rating those Ebay motors are giving?

I need something a tad more torque-y than the 30:1 MFAs, but I believe the next gearing is 100:1.

Looks awesome btw.

THe torque is pretty good for the size, bear in mind the motors are only 16mm Dia, the mfa's are alot bigger arnt they?

[PJ-27]

Yeh the motors are 24mm dia.

Isn't 1,000 rpm unusably high without a further reduction? You must be running tiny wheels.
With 280rpm and 75mm wheels Spinza struggles to turn on any sort of un-smooth surface,

Had abit of time after the F1 to get to work and make some parts, these are the mounts that the Outriggers will bolt to

the wheels are only 35mm Dia, 1000rpm may be too fast but at this weight limit they have enough torque

how big are peoples BW's?
trying to see if my design will be tiny, massive or about right

With wheels half the size but an RPM almost 4 times on a motor with a smaller diameter to me you may struggle.
Spinza has a decent amount of top end, but not enough torque for my liking.
Although on paper it has a top speed of 2.5mph at this scale that's pretty good.

Here's a test drive (Half throttle at start):

The valve is the biggest part!

Looks awesome Tom.
