Shortly after finishing the first Monkeybrain prototype I was reminded that my piloting skills still aren’t up to par and I needed something smaller and easier to fix.
So I shrunk the board as much as I could while still keeping to two copper layers and added four FETs to drive brushed micro motors. Dimensions are 25 * 40 mm.
I bought a micro H frame on eBay and slapped the board on there, along with a camera, video transmitter and a knock off Spektrum satellite receiver.
Although it does fly, it is still quite heavy, even after switching the hardware over to nylon. The only things left to strip down that I can think of now are the vTX’s shield and the FC’s PCB.
