For those who use bullet connectors: Do you cover one to prevent accidental shorting?

i thought of doing setscrew on each side but i wasnt sure if i would then need to flatten both sides of the motor shaft. remember that 37t smartech spur gear i bought? it had a hub on it and set screws on each side from each other so apparently it is something that is done.

as for bullet connectors. i used to have 6.5mm bullets on everything i ran (have switched recently) and you need to use heatshrink on both. just make sure that the batteries always have the female connector. on this project i will be running 8mm connectors on motor and esc but not on the batteries. they are just too much of a pain. here is the thing, first the larger connectors are really hard to get apart when they are put together like they should be so after a few uses you end up pulling off the heatshrink when you are trying to get the connectors apart. also, you have to always be watching and be careful for shorts. although i never had one short on me, my buddy did. just a tiny bit of gold was showing cuz his heatshrink had been pulled back, just like i mentioned, and he had his short several times, both while running and when disconnecting/connecting. so for me i run 6.5mm or 8mm connectors from motor to esc but on the lipo-esc connection i just use the losi ec5 connector. these are high current like dean or traxxas but much easier to solder and large enough for 10awg wire no problem. sure they dont have as much amp capability but i didnt notice a difference when i swithced to them from the 6.5's. anyway, just my experience with using large connectors on lipos.

oh, and thanks guys. i will take your word for it and get all these gears hardened.
