People complain about the bird cage connectors but I have yet to have any issues with any of the 1.5 dozen I have. Having said that, the solid bullets are superior.

The shorter ones here are one of the best for sure: http://www.redrc.net/2011/07/tq-wire...et-connectors/

These are my personal favorite because it captures the wires well and gives you something to grab onto when you need to disconnect them which is a bit of a pain with the low profile ones: http://www.nitrohouse.com/4mm-Bullet...-4_p_2404.html


I've heard these are really good too but I've not tried them myself: http://www.hobbyking.com/mobile/view...dparentcat=409

The Reedy ones look good as well but I've not tried it. Their wire looks really nice too: http://www.redrc.net/2013/11/reedy-p...rs/#more-74432


Hope this helps.
