Status: offline 		I am currently scratch building a 20cc size sport model and plan on having both elev and rudder servos in the rear of the fuse. Instead of running long servo extension leads with multiple connectors I was thinking of cutting off the female conn from the extension and soldering the three extension leads directly to the servo board. What do you guys think of this idea ??

I know some will disagree with me, but that last thing I'll ever do is use an extension that's buried in the fuse or wing, but that's just me. The tried and true method of making a staggered solder splice with proper heat shrinking is fine if one doesn't want to solder inside the servo it self.

As in preceding post, for best results use Heavy Duty Servo Wire and stagger joints.
Soldering direct to the receiver board is not recommended. Solder joint, long fly wire to board, leaves a hard non flexible joint which will break with vibration - use the crimped connector plug.
Following will assist:
