The servo connectors i soldered. Now i had burned some wires the first time with my ugly soldering gun. Thats why i recommended a good one. But i guess once you spend a day trying to figure things out and at the end of the day you find the problem is because of your soldering skills, next time you quickly learn to make it properly.

i think my servos use similar or same connector and a soldered it carefully / the second time/ so now all is fine. With good gun, solder and flux,and correct size heat shrinking its not a problem. I extra potted them i believe using my hot glue gun. I dont like leaving things to chance


The crimp pliers i bought for general use and as i don't use them professionally, till now i haven't found a scenario where they will not serve. Their main purpose was to crimp heated carbon wire to normal heat resistant wire
