Looks like everyone on the Orion thread is racing today....

Can anyone answer this question...?


How do you tell the diff. between a 1-2S and a 2-3S from just looking at both ESC's?

Next how can you tell the difference between a race and a pro just from looking at it?

They both just say Vortex R10 correct..?


I don't see any model# or anything that would give you a hint between the two.


Thx...
