I've been making my own extentions for all the reasons above. I have a few decades of esperience of crimping wires, so with the right tool, IEa crimp tool designed for job, and a good wire stripper that strips the covering but doesn't score the wire, it is a straight forward project to put on new ends to a wire.

However, on one of my last new projects, actually a rebuild of someone elses plane, one with JR servos going to my Futaba RX's, I ran into an unexpected problem. The wire crimp conectors are designed to make good electrical contact, male to female. The housing that hold the conectors are to supply the latching or friction to keep them together. I've found that "futaba" housings don't always latch to "Futaba" housings, IEthe aftger market ones were a slip fit to the Futaba 4" extentions for my ailerons.( I always use a short set of extentions from the receiver toplug the aileron servos into so the wearon the the receiver pins from pluging and unpluging the aileron servos every dayisalmost eleminated. My home made extentions pulled aparr with the same ease as slipping a dollar bill out of the pages of a book when pluged into the Futaba Extentions. Not good.. Test your new ends to make sure they really latch together and are not a slip fit. Some keepers will resolve the problem. Youneed to check to see if you need them.
