So my flying mate bought a "professionally" build racing quad. Beautiful frame, but the worst build I've ever seen. The VTX was were the battery strap goes, under the esc board, on the bottom plate (seriously, check the photo's). The soldering sucked and flightcontroller died. So he had an Airbot stack and Rush Tank VTX and asked me to rebuild it and not pimp it, which is very hard for me. Personally I would have made the frame edge and top plate edge silver colored, but that's just me.
So I took it completely apart. The motors weren't locktited, soldering sucked, a horrible process to go through.
The Airbot esc board didn't fit, the rear standoff would short the thing. Put back the Mamba esc board, re-pinned the connector to the Airbot flightcontroller. If I would have stuck it in, like it was, we would have magic smoke, but this is not a party, also no pope around, so.
Put GPS on it, why not, it's 2019 and they are dirt cheap.
I took the photo's before I put on the GPS (looks terrible). The receiver is not mounted yet (binding thingy) and wiring will be tucked away, after properly mounting the receiver.
Eh Voila, we almost have an Epiquad, ready to rip.
