XLPower Slant Thread Main Drive Gear/106T

I bought this as it's what came in my kit and many other Nimbus 550 electric spare parts to have handy. There is also a so called CNC solid main gear available for the Nimbus 550 electric that is like what comes with the Nimbus Nitro kit but the nitro is a different tooth count I think so don't mix them up.

Does the job
