Here is a pic of a pump and dual gun potted with epoxy in a 3d printed tray. The Gun board has XT 30 connectors added
Interesting technique : ) Did you have to run wires from the Xt30s to the board? What are the two devices in the background? One looks like it may be an ESC?
Yes I use 18AWG solid wire for connection rigidity , solder 2 fully stripped 1/2" pieces to the XT30 bend to fit the holes in PCB. I set the height of the Xt's were the epoxy will just touch the bottoms because the XT30's cases are hollow and will flood out if set to deep.
Just curious: what's different between the new Combat Gear Dual Gun PCB vs the older Dual Firing Board, other than the new one uses SMT devices?
The CGDG-RX uses power from the RX to operate the solenoids . They also include flyback diodes. So you just connect the 2 solenoid leads and go.
Charley, I'd recommend upping the servo lead to 22gauge on the dual cannon switch (from the specified 26G). I'd also stipulate in your instructions to keep the total wire run (BEC/battery to Rx to switch) as short as possible. You should also stipulate at least 22gauge from the battery or BEC to the Rx. I'd also recommend a dedicated high amp BEC (or dedicated battery) for the 6V circuit. Embedded BEC's in off the shelf ESC's will not cut it in this application and should be avoided.

New injection-molded pumps! Full Kit http://battlersconnection.com/large-pump-full-kit/ w/o Motor http://battlersconnection.com/large-bilge-pump-parts-kit/
Man oh man got my pump on Xmas eve and it's awesome. The injection mold is really clean without any flashing. Fitment is real nice. can't wait to try it in different configurations to see how much volume can be pumped.
