The
PCB - receiver / actuator driver / motor driver / BEC
The
PCB (receiver / actuator driver / motor driver / BEC) is a JMP (great
product). I hot glued a small rectangle of plastic to the side of the
edge connector without wires. This and the wires help retain the board
in position. A thin strip of foam tape on the bottom of the main wing
support helps retain the receiver. Placing the receiver in between the
wing mounts instead of on the side is a bit more aerodynamic and better
protected. The JMP board is supposed to be ~2" from the battery and
motor so consider making the rear wing support narrower than the
forward support.
Attach the wing support to the wire insulation
(over the CF rod) with a rectangle of fiberglass fabric .75" x .75"
(prior to covering). The balsa at the top is setup for a single rubber
band to retain the wing. Previously I tried using 4 small neo's. I'm
undecided which way is best. The neo's add a little weight and
complexity and the wing falls off almost every landing but its super
fast to mount the wing. The rubber band is lighter but also comes off
often and gets lost.
