Avoid AIO/PPM DSMa/x FC boards! The orientation of the GYRO may vary depending on Betaflight's version.
The Rx are unspeakable. Forget 1000/2000 as " range ". It is not full range AND it fluctuates.
In short, it's hard to tell whether they work or they don't BUT they are BS for sure!

USB port on the side rather than the back would probably be better and Boot pin is as follow...


CONFIG


A. Board Alignement

Pay attention to board alignement in cleanfligt/betaflight. Sensors aren't correctly set with some betaflight's versions


B. Receiver configuration

*** By default just set receiver mode to PPM_Rx_Input then bind.

B.1 DSM2/DSMX [ EXTERNAL ] Receiver:
- Enable Serial RX for UART3 from the ports tab in Cleanflight/Betaflight configurator.
- Set Receiver mode to RX_SERIAL - Select SPEKTRUM1024 for DSM2 Radio or SPEKTRUM2048 for DSMX Radio.

B.1.2 Bind Procedure
- From CLI tab type "set spektrum_sat_bind = 9" for DSMX or "set spektrum_sat_bind = 5" for DSM2.
- Type "save" and Flight controller reboot. Disconnect USB cable
- Wait a second then reconnect the USB Cable. Transmitter should be turned on while pressing the bind button.
- After cold start satellite LED ( Orange color LED ) should start blinking.
- Bind as default with your Radio.
- After binding satellite LED should be solid.
- Connect Cleanflight/Betaflight and use receiver tab to test that satellite is working correctly.
- If Ok then final step is to go to CLI tab and type "set spektrum_sat_bind = 0"and then type "save". This must be done so that satellite doesn't go back to binding mode when the Flight controller is repowered again.

Note:
If motors start to spin when you connect a battery, in configurator:
- Go to Configure Tab and set ESC/Motor protocol to BRUSHED.
- Go to the CLI tab, type "Set motor_pwm_rate=1000", then enter save.

(Right now) Don't want to go Seby Docky this, Joshua Bardwell that, to perhaps bla bla bla all, to you. Get that like a friend's advise : Simplicity and Harmony, this light little beast is AMAZING ! *** JUST CLICK TO BUY THE LITTLE MONSTER *** Don't misunderstand me. I like them both ( Joshua Bardwell and Seby Docky ), listen to them carefully, the 200GT.  ^^ They would probably give you more than me. Let's see what we get ... PACKAGING  Usually i dislike packaging. But the plastic suitcase style box use to protect and sending abroad this baby makes sens to me. Inside,  the quad smell pretty good (I sound crazy, crazy in love but voila ! nous voila là). Nevertheless, do not expect to much using the suitcase with 5 inch props quads and specially with the 200GT. Oh no ... As soon as props are " fixed ", and right before you fly the 200GT, baby in hand, you won't have the idea to put it back i

The BAT (got me) 1 hundred

Full Speed Bat 100, 1s brushless drone/quad is everything you want. But SPEED ! Noooo ... I didn't fly it yet. Will i ? I received it with (One) missing motor's screw +  One useless motor. ((and) Or the ESCs, Or the FC, Or everything) I had to deal with customer support team, wich handle my case with care. (Thanks to Howard).  + Time goes on. Still doesn't work ! + A lot of fun soldering to come. Probably. Can't wait. The BAT 100 The flying nightmare. GOT ME.  + It is NOT a beginner one. The carbon fiber is tiny. ESC board is tiny. FC board is tiny. Motors are tiny (weak). Flight Time is probably : Tiny. So tiny, Give it a try : *** JUST CLICK TO BUY *** But keep cool. That's a brushless one. You aren't going to change motors often (Cool Kidding). SPECIFICATIONS / PARTS Flight Controller : Teeny 1S F4 6A 4 in 1 http://bit.ly/BGTeeny1sF46A4in1 * You may buy directly on
