Having always run Hitek servos I've decided to go with Savox digital where on the Hitek has 3 colored wires Black Ground - Red Power - White Neutral
on the Savox's they all come out of the servo black no color coding
I'm running Futaba R6014FS receiver and plan on going with Smart-fly Comp 12 any help?

Here's my rant from a couple years ago, https://www.flyinggiants.com/forums/member.php?u=7258.

Some good comments and work-arounds. FWIW I'm still using the 2290s and they're great.

Plug it in, if it works its right, if it doesn't work turn it around.

Look on the plug itself & there might be a +/- in silver ink.
