nice addition whitepony - thanks!
I got a PM with a good question:
Where to I solder and connect the usb wires and the battery wires to? I can't find the info in the post. Thanks.
Seems like if it's not clear we should add it here so others can see/learn. Don't mind the PM of course, but if i didn't clearly show it then let's re-discuss and sort it out.
re-using the wires from the handle, the 3 wires to the USB Mini B charging port
A bit of a closeup of the battery and charging ports. Note that the USB charging port does use all 3 wires, but since i had to mangle it a bit when desoldering the port, i put the white wire in the middle to the bottom side (more room to work at the time as well). So top has black and red, with the middle white connected on the bottom. You can also see the notched out part of the throttle assembly to clear the bind button and throttle adjustment. To keep it straight (what does what), i used the label from under the top cover to help keep them ID'd.
So USB wires on the top should be clear. Note i did connect the center white wire, but several have not and it didn't seem to be needed. I had difficulty finding how the wires connected as well, and saw in one of the pics from Badwolf v1 (angular version) he used all 3, so i did the same.
Then in the bottom picture you can see the red and black connected (black on top, red on bottom.). I had trouble soldering the white in-between the red/black, so i connected it to the middle on the bottom. Then lots of hot glue to keep everything in place.
Next up - battery.
Battery is pretty easy. I purposefully did not damage the plug so i could strip the wire and solder it directly to the + and - on the lipo. Then just plug it into the PCB like original.
Pry/peel off the plastic and cover around the battery. I immediately made sure to label + and - , just to be extra sure i dont mix them up.
Test fit in other half of enclosure.
A bead of solder on the + and - terminals on the battery, notice i kept the connector for the battery to connect to the PCB. Instead of hard wiring/soldering it later i could replace it easily.
Some electrical tape around the perimeter then gorilla taped it up.
