250 Race Quads & Devo Tx

Hi all & thanks for reading. Being fairly new to this platform & protocols, I'm just wondering what folks with the Deviated Devo10 are using for Rx's on their 250mm size racing quads? I read a lot of folks are running FRSky stuff using the Taranis but what are the Devo set using? I'd like to keep it as small and light as possible (i do have the Walkera 10ch Rx but it looks too big).

Thanks in Advance for any response.

I used to use Spektrum satellites (from Orange and Lemon) but had a failsafe event at ~350m out.. I installed a CC2500 since and fly FrSky now (D4R-II).

...any rx with PPM. If you are not going to mod your Devo for FrSKY, simply use one DSMX receiver.
Cheap ones to start with are Orange e.g. R615X or the Storm S603 ( longer range).
There are plenty that could be used with more than 6 channels, e.g Orange R410x , R415x, R 720X, R 820X and the fsfly F701 & F801.

Thanks for responding folks...haven't yet done any "hacks/mods" so that remains a prospect as i do want to do the V222 mod as well. Looks like for now i might go DSMX sats, but can i just use a sat or will i need to bind it off a full Rx first? and if so, can i just bind a sat to my AR7200Bx, then use the bound sat on the quad?

Sorry for my ignorance to date, all i fly atm is bnf stuff even though i have CP & full Rx's it's all Heli stuff.

I am interested in the FRSky mod, but as far as i've read, it can be done but not telemetry friendly? Any update on this please? Also any links to mods would be most appreciated with THANKS.

DSmx SAT only = no Spektrum FlightLog
Do you really need PPM?
Spektrum AR6210 including SAT (supports FlightLog) is a good receiver.

There are at least 2 current FRSky / CC2500 threads.
There are >=2 pull requests in deviationtx team repository for frsky telemetry optimizations for the offical nightly-build.

Well,....... thanks for that Thomas, my mind just turned to jelly...haha. Will search out that info. and try to make some sense of it.

Do i need PPM? Buggered if i know...i am too new to know much of anything on the programming side of things....mechanical stuff fine, but i tend to stuff up big time when i try to do 'new to me' stuff on computers and don't understand the language (>+50 & approaching dinosaur status)....techy stuff makes my head hurt.

Thanks for reaching out though, it is very appreciated.

Pardon me, I do not use FCs and PPM / digital bus signals.

My colleague used the AR6210 + SAT + TM1000 (all single servo wires) in his bigger quad.

So it depends on the flight controller, if you can connect each servo cable to the FC.
IMHO not all FC support that??? Some may require a ONE digital cable solution (PPM, SBus, SUMD).
The FC vendor should describe it in the manual.

It is more used for heli FBL systems.
The PPM makes the sense that you only have 1 wire instead of e.g 6 wires.
If you would need to use 7-12CH, that is much easier with PPM.
e.g 5 channel gyro gain, 7 channel bank switching, 8 channel rescue activation, etc.
>6CH does not work with AR6210.
And for some flight controllers you can only hardwire 6 channels, but not 7-8 channels so you might loose features as above.

See the Spektrum / HorizonHobby homepage for TM1000 and AR6210 manuals about Spektrum FlightLog telemetry.
I am not sure why one would want to miss this great feature. Makes only sense if you do not have the space for a TM1100 / TM1000.

And then it still does make sense to first ground test the receiver signal by using Spektrum FlightLog even you can not use it in the air.

Carbon frame: Be careful with short antennas! The carbon may shield = high antenna fades.
You will notice that with FlightLog, but may not notice it without it (e.g different fades on A + B, e.g high fades on A because of bad mounting the receiver).

Hi again Thomas and thank you for the added info. About all i did know out of it all was to be wary with the CF frames. As for the rest, i should have given more info. and that was my bad.

The kit i bought to build is the FPVModels ZMR250 which comes with the CC3D FC, 200mW Aomway VTx w/Cl antenna. Also has DragonFly 1806/2300kv motors and 12A ESC's.

How it all works and talks to each other is lost on me after that....i got a long road of understanding ahead. S-bus?...SUMD and on & on..bit of a lost cause i am haha.

Even reading this thread over has my head spinning, so will give it a rest until i'm up to that part of the build before overloading myself with too much info. for now.

You folks here are great, and i have plenty of homework to keep me going for a while now.

Regards & Thanks

For the record, three of the four FrSky telemetry pull requests deal with display issues: there are telemetry values whose names are blanks in the spinboxes, the sensor hub (which is considered obsolete and no longer sold by FrSky) voltage readout is wrong, and there's a question about whether we want to use RSSI values or the thing that's currently there), and the fourth is a bind issue that only affects some users.

CPPM (Combined PPM) combines a multiple PPM signals into a single serial line. Open standard, very popular on multi-rotor FC boards. SBUS is a similar system from futaba. I don't know if it's open or has been reverse engineered, but you also see it on FC boards. OrangeRx's newest line of Rx's - the #20X version - come in both CPPM and SBUS versions. You can also get Rx's from FrSky that support one or the other of those.
