this is used to extened the hitec servo wire to the board. some other servo's have even shorter wire than the Hitec and this should work.

Hey there -
When using the Blue Bird BMS-385DMAX Digital Servo (Metal Gear) on the T-copter frame, I had to choke up the rear boom into the frame, basically to the back of the receiver. (It is stopped by a mounting bolt for the stand). Is that the correct installation or is this lead a little short for that servo?
