Is anyone aware of an inline component I can use to convert normal PPM/PWM to SBUS?
Basically what I want to do is use a ZOHD KoPilot (which only supports SBUS) with a Frsky D8RII receiver (which does not support SBUS).
Why? Because they're great receivers, support telemetry back to the Tx, and I have many spare ones lol.
So I imagine you'd wire it from the Rx using male to male servo leads, it would sit inline between the Rx and the flight controller ... it would convert the PPM output from the receiver across multiple channels into the SBUS signal required by the flight controller.
Any ideas? Ta!
Not tried this but this converter might work http://bit.ly/2GYDIKS (http://bit.ly/2GYDIKS)
It suggests either sbus in or out and pwm.
Another similar http://bit.ly/2H2pQiF (http://bit.ly/2H2pQiF)
I've used the older version of this RCMile one :

Sometimes it wouldn't boot up right so needed a reset ( older version ) but that was very rare it happened.
hmmm - might as well buy a new rx at that price
I was thinking the same!!! New rx cheaper and probably more reliable than some converter.
Cheers for your response too Ched... think i'll just splurge on a new receiver, less faff :)
"Basically what I want to do is use a ZOHD KoPilot (which only supports SBUS) with a Frsky D8RII receiver (which does not support SBUS)."
May I suggest you read the instructions again. The KoPlot lite comes with leads to take PPM/PWM from the Rx channel OP's and use them. Or, you could buy a Jumper R1+ which is D16, gives S-BUS and weighs 2gm https://www.quadcopters.co.uk/jumper-radios/jumper-r1---d16-frsky-compatible-micro-receiver-with-sport-and-sbus (https://www.quadcopters.co.uk/jumper-radios/jumper-r1---d16-frsky-compatible-micro-receiver-with-sport-and-sbus)
Now there's an answer.
I had not seen that - oh well problem solved. That'e excellent, thanks!
Edit: that's the KoPilot Lite .. is that the same as the KoPilot?
Not seen 'just' a KoPilot. The 'light' is for fixed wing. Is yours the same as this one https://www.youtube.com/watch?v=IZrWgzjxe_U (https://www.youtube.com/watch?v=IZrWgzjxe_U)

A Google search will bring up loads of info.
Hi Steve
I have just installed the KoPilot into a new AR Wing and it works great.
Even the auto assist launch works. I put the TX on the ground, set the switch to RTL, put the throttle to max and threw the wing. Bingo, the motor started and off she went.
The only problems I had setting up the KoPilot was that I could not set the auto level with the sticks. Turned out that I had set up the stick throws (rates) and they were not fully traveling to 100% throw rate.
Second problem was that the elevator trim on the radio is reversed. Wing mixing is done in the KoPilot not on the TX.
On her maiden she was diving, so up trim was added. The more I put in the worse it got. Brown pants moment.
I brought her in and on investigation it seems that the elevator trim is reversed. Never seen that before on any of my auto pilots. Just need to remember that.
The aileron trim is OK.
It's coming in the Zohd Dart250 so whichever one that is.
Good to know, Drone 5! I bet that woke you up lol
That'll be the 'lite'. I've got a ZOHD Dart 250g. But, I've not started to put it together as I've been playing/updating my new Jumper T16 Hall Pro with the internal multi protocol module. I'll be using the Jumper R1+ Rx (S-BUS) D16 FrSky protocol. I've looked at the main power and the initial install will be two 18650 Li-ion cells. A possible alternative is the 21700/20700 Li-ion cells for more endurance but they are 10g heavier each cell and may push it over the 250g.
I was toying with buying one of those too actually, I'm still using a 9XR Pro but I have never gotten along with it, the form factor is just really bulky and it feels naff. So looking for an upgrade ... Jumper T16 is top of the list at the minute.
The Jumper T16 is a 'Futaba' case knock off. Uses OpenTx and has a JR module slot for TBS crossfire etc. The Taranis is a smaller form factor but and it is a big but they are trying IMO to lock users into their equipment with the V2 ACCST protocol and ACCESS. Lots of videos on YouTube about T16 from Joshua Bardwell, Paweł Spychalski, Painless360 and others. Also, 'Jumper Technology' on facebook.

I would be interested to see you you get on with the Dart 250g. I was toying with the idea of trying a plane and the sub 250 gms appeals as I am only flying sub 250 quads.
Don't forget, as things look at the moment, even if the plane/quad is under 250g comes the 1/7/20 then if a camera is fitted it still needs to be adorned with your operator number to be legal. Which means you need to register, pay the TAX and take the test. Just saying. IMO its bloody nonsense. If my childhood self was flying models now I'd be a criminal(society would disintegrate, death destruction and pestilence would roam the land. Or so the CAA would have us believe)!
I am the only person in the world (it seems) to have hated the bigger ZOHD Dart... I simply could not get it to balance, although when I did fly it it seemed to fly well albeit the CoG was right out. Not sure what was up with it (perhaps bad CoG markers on the foam?). There was no flight controller in it though.
When I was ripping it up I discovered it also had 2x lead weights buried in the nose to try to make it nose heavy which suggests to me that it is a fundamentally flawed design - I hate carrying dead-weight, especially when we're trying to get something as light as possible for regulatory purposes.
So - I am interested in seeing how well the 250 version flies.. lesson learned I will be trying to use the "official" flight controller this time. But the thing is, we've always historically railed on aircraft that needed a flight controller to fly, so if one is actually needed to fly it properly then I'm not sure how I'll feel.

I did realise that, thanks. You are probably right and I will have to go on the naughty list at some point, just trying to delay it as much as poss in the hope the gov come to their senses :D
So anything I currently buy will be sub 250 gms.
As you say totally stupid rules that won't solve the problem at all, but that's just the gov showing joe public they are doing something plus they are trying to clear airspace and sell it to Amazon and co....
Anyway looking forward to your dart 250.
