You can use brianG's speed calculator to figure out the KV for your motor:

I didn't know the DST was available yet.
Where are you getting one from?

I would take an around 150g heavy outrunner.

i work at a rc-store in sweden and we got some dst truggys i stock :)

i'm going to mount the ceter-driveshafts directly on the motor shafs so there will be no centerdiff or spur !!! do you guy's realy think a .25sice outrunner will be strong enough ? and are 870kv to mutch ? will a eflite .25 size outrunner be enough ?

[MetalMan]

What is the differential ratio of the DST? That will determine which kv to choose.

i don't know ! but mane 13/37 ?

But wil the eflite .25 ourunner have enough tourque ?
