Big Dave 3 Design & Build

[maddox10]

Gravity 3 was geared for 15km/h.
Tough as Nails for a smidgeon faster, 18km/h
Bullfrog can get up to 14km/h.


Lets take a hypothetical setup.

250KV, 37V 250mm wheels.

With a 5-1 ratio you end up with ludricous speed.
0.25m x pi x (280x37)x60/1000= 97km/h

With 130KV motors, it's still more than 40km/h

With 130KV motors and a 15-1 gearratio you're back in the normal range. Between 12 and 20km/h.

Some machines are build to be faster. But getting the power to the floor is a problem.

I get 11.2km/h with the 15:1 ratio with the 130KV motors, 16.4km/h with the 250Kv motors.

I cant see the pictures?

Are you on a Mac? I've tried it on PC/Android/iOS and it displays, although it doesn't work on my work Mac.


Has anyone ordered from Alien Power before? Almost everything shows as out of stock.

Tried on all of the above, gives a no-entry sign as its some protected google doc/image
