Thanks for your answer
So, after getting the RMF calculations done in societyofrobots site, i got this:
And the motors I found don't have the RMF needed, thats why I'm asking... In the picture the needed RMF is 4.02, and the max I found was like 0.5...
I would like to learn of corse, if someone can explain me how to do I would be very pleased.. And I don't need the exact link of the motor, just links of sites where I can buy good motors for good prices, and the way to get the motor that suits me :p
