Robot Marketplace has the motor datasheet http://www.robotmarketplace.com/products/RP-MAGNUM775.html

Thanks i was being lazy.

stall 138.7A (130A by robotpowers website but that could be old info) No way in hell im running that on a sabertooth 2x25 would not recommend you do it shreddy.
That is victor and sidewinder levels.

Is the magnum540 just got a 540 motor bolted on the back with the same gearbox. I remember seeing on the rfl forum talk of an actual magnium 540 a while back but cant see it on robotpower or rmp website

The 540 is a 36mm version with a 540 on it. the torque would probably be less but its the same construction so it would be similar strength.

Probably not as popular as the 775's because everyone wants the extra power.

the 540 is $67 including gst.. Free ship if you pre-order and live in Australia!

Well will probably be in for the 2x 540s. Whats the deal with pre-ordering those? Will be added to website I assume?

No... it was a bug in the shipping... Ive fixed it, It wasnt giving the free promotion for some reason.

order placed

heya bytraper, any idea where one might find some drawings / dimensions for the 550? i see that you have some listed but i'd like the hole positions on the flanges mostly

Hey Jaemus,
wont know for sure until I receive them!

fair enough. fingers crossed that will be soon!

Got mine friday. Look pretty good. Might be a while before I get to battle test them though.
