New 4s batteries.
New Naze32, will run Cleanflight initially then maybe switch to Betaflight and see what it is like.
New D4R2
New Sunnysky 2207 2100kv
New Kiss ESCs I will flash them to the latest BLHeli firmware

The only original parts will be my video system and my old frame.
Although I may switch back to the Fatshark 250mw vtx.

All the old parts will probably end up on another frame for Jacob at some stage.

Wow, this thing is filthy inside, time for a clean before rebuilding it.

Stambo make sure you don't put to much heat into the kiss esc's when soldering, this has been said to help with magic smoke,

Nice haul mate,

Looks like you've got some nice pieces there Stambo.
What's the bec your using for the rebuild?

It's a little 3amp mini ubec from the guys I got the Kiss ESCs from.
Hopefully it will be enough to run the FC and RX and keep the Mobius charged.
The video TX and cam are both capable of running 4s but I will eventually need a 12v bec or a little regulator for some LEDs.

I was wondering what to do for power distribution when I spied a faulty PC power supply.
I took it apart and found a bit of circuit board with some nice wide tracks on it.
Out with the Dremel and cut it to size.
Sanded the tracks a little and flowed solder over the whole things, good enough for me.
Sorry about the poor quality pics, camera battery was flat and had to use my phone.

Did the remaiden, it did not go completely to plan but I am puzzled as to what happened.
First hover, about 2 feet off the ground in self level, gave it a few flicks to test reactions and it just fell out of the sky.
I have no idea why, I checked motor and ESC temps, one motor was warm, the rest were cold.
I checked all my connections and tried again, acro this time with no issues.
I put in a new battery and put on the goggles.
I also very quickly put a huge smile on my face.
This thing is fast, real fast.
Took it reasonably easy the first couple of flights then just went for it.
Checked the motor and ESC temps after each flight and they were stone cold.
Running DAL 5045 bullnose at the moment but just for interest sake I am gonna try some 6040.
I will probably lose a bit of handling but I need to know how much faster it goes.
I will upload some videos when I finish editing them.
Been a little busy on my patch of dirt.

Finally edited my re maiden video.
