Can anyone recommend a good source for servo connectors in bulk?

The nomenclature seems a little inconsistent, but the "JR" housings are likely what I'm after. I've found the Hobbyking sets (https://hobbyking.com/en_us/jst-sh-s...pairs-set.html) do what I need, but they include parts I don't need and appear in short supply. I have plenty of crimps, so preferably just housings, but happy to look at 2 or 3 pin sets.

I use them to wire up things that plug into your typical RC receiver.

Looking for maybe 100 in the short term.

The JR style seems to fit pretty much all receivers without modification, whereas the Futaba ones often need a tab trimmed off to fit in Sanwa receivers, for example. Is there a better universal option?

Thank you! Assuming you mean hansenhobbies.com, it looks great

I use hansen hobbies. I'm not the best with their crimper, but that's where i get my pins and housings.

Hansen looks to have a good selection at reasonable prices, so I've pinged them for shipping costs to Oz.

Turnbuckles and crimping connectors. Not my favourite parts of RC racing

It's a little off-topic, but I'm slowly getting better at it. Where I draw the line is the PH-sized connectors, which are too small for me to handle in any quantity, so I outsourced that!

Seeing as your down in in Aus you may get a better price inc shipping using this site from Newark, https://au.element14.com/amphenol-ic...d&exaMfpn=true

The connectors are $.17 Aus each. You will also need the pins as I don't know if others will fit. They are more than Hansen Hobbies but I know these are name brand Amphenol connectors. I've also used the Molex and they are just as reliable.

It's hard to tell, but I think they are square-edged (the JR ones have rounded corners) and don't easily fit in as many receivers. Can you confirm otherwise?

Had to look but they are square edged. I use futaba 304sb and 614 receivers and they don't have rounded edges so these fit without any problems. I'd look but don't have access to any other receivers right today.
