I have a losi electric conversion can you use the metal center diff gear with the metal pinions? How do you mount a mamba 2200kv motor do you have to buy countersunk screws that will go into the motor?

There's alot of good info on the other threads answering these q's but I'll help a little.
Yes the first conversion kits came with metal spur. their just noise some guys like it for durability. 3mm 14mm long screws are what will work 16 to long 12 not enough.
