Review on KNIPEX 46 11 G0 Snap Ring by Jamie Rogers

I would recommend this Knipex circlip removal/installation tool to anyone looking for a tool for their small external rotors! I've browsed the RC pages to look at the tools people were using, but none of them had the sharp nose I needed. With a bit of luck I came across this snap ring puller from Knipex. The tip of the needle is made of chrome vanadium alloy, strong enough for small snap rings. Just don't throw them on the floor. ;-) The adjustment screw on the tool is a great feature to keep the clamp from expanding too much. This tool has made servicing my 4014 400KV motors easy and I am very happy to have a pair. It's difficult to estimate actual needle size without more details, so I've attached a few photos to help. The pictures also show a 4014 400KV motor and a ballpoint pen. If half the point of a ballpoint pen fits between the teeth of the locking ring, this tool might work for you.
