How well do you solder? Are you comfortable taking apart servos? For about 10 yrs I've been customizing the length of servo wiring. Making a clean install. Soldering cable to length and crimping plugs, Airtronics and Futaba, Cars and Aircraft. Being a hobbyist you find what easier. Extension maybe cumbersome and zip ties I am into. Photos of my extension kit I put together. Aircraft you to customize especially Jets. I does look cleaner installs.
