@badger1, When my quad got all muddy, a quick rinse under the hot tap, avoiding the electronics, got the worst of it off, then strip down and clean, quick repair to the VTx, it's all good again ~~

Thank you for all the stories that come to experience in this place, which is very Dr.

Am hoping someone may be able to give guidance .
Please bear in mind that I';m new  to tech , ta . - using the terms in the thread title doesn';t mean I understand them fully .

Currently use cheap 250 quads , but at the stage of really really wanting better motors and escs with a braking action .
(was going to get cobra motors and little bee esc)
(warning - "beginner fails at flashing esc " thread soon to follow !)
So ;
I use a spectrum dx8 (old ,2nd hand ,but on dsmx) ,and standard ar610 rx ,- do I need to get a PPM receiver to use the braking function on the esc ?
If so , a "lemon dsmx ppm " seems to be available on ebay  .
( I understand that a new  learning-different-wiring -experience awaits)

(Research does  through up just using a dsmx "satellite"  receiver on its own but that';s a whole nother bag of weirdness to me )
(also , I understand that the easy answer may be to use naze fc , but am not quite ready for another protocol-learning-experience .)



You can use DSM sat and still have OneShot.  It';s just that OneShot doesn';t work with PWM.  The sat can be connected to the Main port in DSM mode, and the Receiver port set to Disabled + OneShot.

A word of warning, most if not all sat receivers are powered with 3.3 V and the ports on the CC3D output whatever voltage you feed the CC3D (typically 5 V).  You need to solder the VCC cable of the sat to the 3.3 V pad in the top right corner, so not exactly plug and play.  Check the specs of your sat RX, perhaps it is 5 V tolerant and you don';t have to do this.

You can use PPM of course, but the power requirements for the sat RX don';t change.

Thank you.
Have took on board the 3.3 to 5v warning re sat straight into cc3d.
Will go ahead and get a lemon dsmx ppm rx .
AsI understand it the satellite bit can be plugged into the main rx bit and receives 3.3v therefrom.

I have just bought one of these for cppm as I too have a dx8 and want to get rid of the big clumbsy receiver. This is going to be plugged in on my atom cc3d here is a link its on hobby king http://www.hobbyking.com/hobbyking/store/__73005__OrangeRx_R616XN_DSM2_DSMX_Compatible_6CH_CPPM_Nano_Receiver_with_Failsafe.html

That really is small !
Have found that a remote antenna is really handy on a 250 carbon-type frame
(Seems that way anyway for me going from Orange r615x to spektrum ar610)

Thanks for replies - has motivated me to restudy the "input" page on librepilot wiki  - is slightly less scary now.
