Which receiver for e-glider (Taranis X9D)

Post by Hugo123 »

I have an old Taranis X9D from 2013 (so not the PLUS version) .
Never used it so far, just recently updated it with the newest version of OTX.
Now, after a long time not being active in RC modeling, I started building a simple electric sailplane, and found out my FrSky receiver I bought together with the transmitter (V8R4-II, never used either :-)), probably needs to be replaced for a new one.

I'll have 4 servo's + simple controller for brushles motor, so will probably need a 6 channel receiver.
Had a look at the FrSky website... lots of options to choose from. ACCESS or ACCST?, RX, X/XM, S, D, V..?
Getting a bit lost and not sure which ones are compatible with my old X9D.

Which receiver would you guys recommend? Doesn't need to be FrSky by the way...
As mentioned, for a normal e-glider, nothing fancy, normal outdoor use.
Any suggestions much appreciated!

Cheers,
Hugo

Your tx does not support ACCESS rf protocol. SO you want an ACCST rx.
A RX6R or G-R6X have 6 pwm output pins. The G version has a built in vario.
(Some say that vario is not as good as the separate vario.)
I use R6XR frequently.
There are multiple versions of ACCST.
Unless you upgraded your RF board you are using V1, the original.
(Not the same as upgrading OpenTx.)
The newer versions were to correct a seldom encountered condition where a bad frame could cause unexpected
servo movement. It is very rare, I use ACCST Ver.1, and do not believe I ever encounterd the bug.
For gliders it would seldom cause a problem if it happened unless low or under power.

P.S. There are also FCC and LBT versions of receivers and transmitter rf firmware. Since your location is not shown, no help here on which one to get. Buying from a local dealer will probably help you with this.

Why Hugo?

8 channel RX. For a start, it should do.

@ Dean:
Thanks a lot for your explanation, all clear.
G-RX6 for sure looks interesting, nice compact and lightweight. And I would like to try flying thermals with some electronic help :-).
I'm from The Netherlands by the way, just updated my profile.

@ Kalle:
This is the receiver I already have: https://www.frsky-rc.com/product/v8r4-ii-2/
I will use it for simple planes, for instance Lidl Plank.
But it's 4 channel only, so for 4 servo electric glider I need something else...

The V8 series precedes my involvement with FrSky, so I know very little about it.
It is an older rf protocol than X series ACCST I use.
I believe it supports the older V8 protocol and the somewhat newer D8 protocol.
The 2 series receivers I mentioned are D16 rf protocols. Your older tx (like mine) supports both the D8 or D16 protocol.
The D16 supports 16 channels and telemetry.
The V8 receivers, to my knowledge, did support telemetry in D8 mode, just not very cleanly compared to the D16.
Altitude and and its change are fun for me to play with in my e-gliders, Also knowing battery condition is a security blanket.
The whole telemetry aspect is a main attraction that brought me to FrSky.
(The other being sensibly priced tx, rx and telemetry sensors.)

I know UK uses LBT and most of the rest of the world, the US for sure, uses FCC.
I think your tx was before LBT became a UK requirement.
Best visit a local club or rc dealer for Netherlands and the rest of EU regulations.
OR...
Hopefully, one of your countrymen or someone more knowledgeable than me will chime in.
Kalle is for sure more knowledgeable than me and may know the correct answer.

The Netherlands were great to visit.
Friendly people, great cheese and beer.
My wife and I used to drive up from Germany for brunch and sight seeing.

Good luck
