Guys, I went to Jaycar today and got some plugs and sockets which make great combination switch and charge sockets for EPP wings. (same idea as the “Blackjack”)
The idea is that when the socket is empty, the plane is switched on (there’s a micro switch in the socket). When you put the charging plug in (or a “dummy” plug) the plane switches off. Glenn (Zipper) sent me one with my Drongo wing, and it works perfectly. The ones I got today are similar but a bit smaller.
The plugs are part no. PS0520 (Skt PCB DC switched 2.5mm).
The sockets are part no. PP0511 (Plg line DC 2.5mm 10mm shaft) Both items were $1.55 each I think.
All you need to do is a bit of soldering. You take the lead from your battery, and cut it, and bare the four cut wires. Both of the positive leads solder onto the centre terminal of the plug. The negative lead on the battery side solders onto the higher side terminal, and the other neg lead onto the mid terminal. They're really dead easy to solder up. I'll put a picture up soon to show how it works. Fit the plug into the wing and optionally use a bit of hot glue to hold it firmly in place
Make a charger plug by soldering the pos and neg wires of a servo lead onto the plug. Red goes to the centre terminal and black to the outer one. Note - keep them separated so they can’t short out.
If you like you can leave the charge lead plugged into the plane to keep it switched off, but the only problem with this is that it sticks out, and I kept absent mindedly leaving it in when working on the underside of the plane, so it got pushed and wiggled badly. It survived for a few weeks but finally went glitchy.
So it’s better to put a short “dummy” plug in, and I found that a piece of the soft plastic tubing which is used to hold flyscreen in, fits into the socket and switches it off. It’s also flexible, so you can have it sticking out a bit, and even put a keyring thru it, and it won’t hurt the socket if you wobble it.
A very cheap, light and effective way of making a switch and charge socket combined, flush mounting and all!
