If you bought the AR6300 nanolite receiver, you will need servos already fitted with the appropriate JST connectors or some way in which you can adapt the standard servo to JST connections. This product provides such a solution. It works perfectly. The wires are very thin to decrease its weight. But, in spite of my clumsy fingers, the wires have not broken yet. I would just caution that after plugging the adapter into the receiver, you will find it difficult (but not impossible) to remove.

They are easier to buy than make. Just think they are a little pricey.

A good connector when using standard servos. Saves time and effort and makes assembling various size components quick and easy.

Just what I needed to hookup my ESC to my 6310 receiver.

These are certainly a quick fix for adapting a servo with JR or Futaba connectors to a micro connector, BUT Horizon has 2 different connectors for their receivers with micro connectors! These are for the ones with the ZHR connectors, not the SHR connectors, which the 6410 series receivers have! Make sure you know what you are ordering, or you may have to buy another set of adapters which will cost an additional $6.99 per pair. It would be great if Horizon would be sure to mention which connector you are trying to match before you are disappointed with their deceiving product line!
Now, in all fairness, I had this issue with a purchase, but the Horizon rep I spoke with did make it right. Kudos to you, Sir! That being said, be careful of your purchases from HH. You could be in for a surprise that is less than pleasant.
