C4 vs Mamba Max 7700 motor
 

How would you compare these motors I bought the c4 and i wanna know what the amp draw on it is in comparison to the mamba 7700 they both have the same KV but whats the big diff between the motor and will i get a hell of a speed increase in going from the lehner4200xl to the c4?

IIRC, the C4 is simply a rebadged Mamba Max motor. So, there is no difference between the two.

What vehicle is this in? That's a good bit of a difference going from a Basic 4200XL to a 7700kv MM.

its going in a 1/10 tourer... so is there an amperage diff on the mamba and c4

No, they are the same motors. The C4 just has a different sticker on it.

yup, pull the sticker off the c4 and its green
