With great power comes great electricity bill.

i think they are about equal: XL motor with about 220 rpm and 40 torque, and L with 400 rpm and 18 torqueSo gearing down L motor 2:1 gives 2 times more torque.

They are close, but XL is still more powerful with 2.21W of mechanical power at 9V, where as the L motor has 1.85W of mechanical power at 9V.

If you really want some power go for the buggy motor, way more powerful than the XL motor.
Even the best can be made better, but most important is to be excellent to each other and party on dudes!!!!!!

Semi on topic, how many L motors can you run off one battery box with the new V2 IR?

you can run two L motors, any more would result in receiver cutting off when you would stress the motors

So if you geared down the RC motor is it stronger than  a XL / NXT at the same RPM?

Yup! According to Philos updated measurements the buggy motor produces about twice as much mechanical power as the XL motor.

Yesterday I tested 2x L motors as alternative to 1 XL motor at my middle-scale awd mocs like this
http://www.eurobrick...c=72502&hl=9395
or this http://www.eurobrick...=73762&hl=8081.

I built light awd chassis and mount 2L motors. The weight was simulated by two battery boxes (of course with accus)
Weight of chassis and moc car about 900-950 g. So I can compare them.



2L shows the same torque, but better acceleration, 1,5 times faster speed, compact and better mounting possibilities.
Our next awd car will be with 2x L motors;)
