What electronics are you running? I just bought a surpass 2440 to go in mine. It’s brushless 4000kv . I don’t know if that’s faster or slower than stock. I understand KV but Turns don’t compute to me

Castle 1007 6350kv (sensored) and mamba micro esc, 10A BEC, castle BT Link, spektrum SR315/SLT3, NSD rs100 hv, ht micro servo. On 3s-4s
As far as making sense of the value of the motor numbers.. as a general rule the first 4 digits will be the diam and length of the motor and second 4 will be the KV. Windings refers to the physical wraps of copper wire in the motor around the stator when you put electricity to windings it creates a magnetic field around each coil. which creates a field which interacts with the magnets on the rotor which generates force. So easy way to remember that is more and thicker windings you have more torque but at lower speeds. Less and thinner windings & looser coils make for higher speed at lower torque.
Castle’s special so they have their own system that is more to do with stator size and it’s pretty confusing tbh. However they do make a decent motor. Just don’t learn from them on the number tip cuz they’re the exception.
This may help…

The KV rating of an RC motor tells you how fast the motor spins for each volt of electricity applied. Here’s how it ties in w/ windings….
A High KV Rating: motor spins very fast with fewer windings. It’s good for rigs that need to go fast but don’t need much strength to move.
Low KV Rating: the motor spins slower but has more windings, giving it more power to push or pull. Which is needed for heavier/larger cars that need to handle tougher conditions.

I was wondering from where you managed to get a 3.17mm 0.5 mod pinion for this motor.. i cannot find any around... any help please?Castle 1007 6350kv (sensored) and mamba micro esc, 10A BEC, castle BT Link, spektrum SR315/SLT3, NSD rs100 hv, ht micro servo. On 3s-4s

I drilled the stock one out with a 1/8” bit.

Theres quite a few .5 mod 1/8" bore (3.17mm) pinions out there that will jive with the 59t stock spur, alternatively you can order a 57t spur for the grom which is a .8 mod and pinions for that are much more abundant in higher T count. mine is a bit of an accidental/custom setup where im running a 30t .5 mod pinion on the stock 59spur. its actuallly an 8mm bore, it so happens the 18t pinion i was running served as a perfect adapter to fit inside the 8mm that i bought.
