Fix it somewhere with Zip Ties, and yes, nice towel, wondering if there is also one with the Wookong Logo
If your NAZA controller is dead center of the bottom board like mine is, you will only need one extension for the pitch servo. I am using a 12" JR extension from my LHS, but you could probably get away with a shorter one. I zip tied the excess to the bottom board leaving enough slack for the servo to pitch full range. The roll servo has plenty of length without the extension. Using HiTec HS-65 servos.
Sometimes when you run servo power straight from the naza you get a twitch.why not? naza bec is way enough for just 2 servo's
