Sorry hk but this item is very poorly made, it's grub lock screw did not go deep enough
and lock against flat on shaft, so it part stripped out the first two threads. I had to round file a deeper groove on shaft to lock it in using loads of lock tight, hope QR is going to get better
in future, as I am already looking for other places to buy my rc gear from.

I bought 3 of them. The hole is too small for 3.17mm motor shaft. I tried applying heat but still could not fit. Eventually I broke one of them by trying to hammer it on the shaft.

Be careful when you tighten the screw, thread brakes easily. I recommend filing the locking screw end flat, then thread goes little deeper and doesn't brake that easily.

Smooth teeth but to little metal around the grub screw.

You need to make a deep flat spot on the aksel for the grub skrew to grab desent.

I am using this pinion for scale applications in 450 helis where a higher KV motor is used. It helps to keep the amps low on the ESC. Take care in programming soft or very-soft start on your ESC so you will put less stress on the main gear.
