New crew - old spot

A new little crew just join my collection.

I really surprise how stable it is, very easy in tuning, it just fly so well. The cheapest stack I ever bought from banggood Super_S F4 $28. The stack is soft mounted by 3 layer double side tape under ESC and a bit of soft foam between ESC and FC

Again I serious suggest this buzzer, I sound very loud. It save my quads a lot of times https://goo.gl/Vf3p63

Notice:

  • Need to add some SMD caps as near as the power pad of ESC for get clear video
  • The Super_s F4 stack only support 0.5 A bec not enought power for XM+, VTX03 . So I added 1A step down for serving VTX, camera and buzzer
  • Softmount the 4 in 1 esc to the frame with at least 3 layers
  • Put some very soft foam between FC and ESC and only connect them by 2 screws but not all 4 and don't tie hard leave a very small gap so they can absorb the micro vibration => this might only be true for small build and not very strong motor
  • Don't let anything touch the FC on above leave some room for it even 0.5 mm

Parts list:

**Update:

  • upgrade the motor to RCX 1103 78000kv, Amazing!!!
  • change ESC to Racerstar 6A 16x16mm. Fpv feed very clear, don't need cap anymore https://goo.gl/8zjhq1

Flight video

Updated: Having improvement for X2 ELF 88mm buid, Swapped Hulkie prop to Gemfan 4 blade 2035, most of fpv noise and vibration at top speed disappear

Just curious, what's the step down converter for?

I think I am in the same position as you are at this point. I am not sure exactly what you actually did with the step down. My board reacts and operates well in Betaflight but will not "come to life" on battery power alone. Do I need to send power directly to the FC beyond the 6 pin connector/

HI Rhygin. Here is how i connect things together:

  1. FC connect to ESC, If the ESC not provide power then your board having problem, you can try to connect FC to battery directly but be-careful with polarity ( + on pin 5 and - on pin 6) http://img.banggood.com/thumb/water/oaupload/banggood/images/EC/0A/f9c08e65-1f8b-4301-a503-8f22aca0e066.jpg
    • receiver XM+ connect to FC for power
      But if you cannot power the FC via standard provided cable you should take a short video and open a ticket send to after sale support they will take care for you. After that you can try to revive the board ^_^
  2. Step down connect to battery.
    • VTX03 connect to Step down
    • Camera connect to VTX03 output +/-
      Why I need the step down. It's because the FC bec only 0.5 mAh it cannot work stable for the whole system especially I use VTX03. So the Step down would responsible in provide power for VTX and camera.
      I connect camera to VTX03 out put because the VTX03 has filter too and I think I got more clean video.

Yes that me on MMC, It's weight 47.5g. This guy a bit heavy due to the frame and I swapped 6 nylon screws to metal screws, 8 small smd caps add 3g more
