Flysky’s new Ibus 2 sensors 1st look

[@klausmewes3622]

They seem to be nicely designed. However they can't coexist with the old iBus sensors. At least from my preliminary tryouts. As soon as you set one of the 4 'newport' NPA-NPD inputs to iBUS2 you are locked-in to iBUS2 and all the other NP inputs have to be iBUS2. You can still set them to S.BUS for communication to a flight controller for instance, but not iBUS, thank goodness. I even tried doing a double RX configuration, but the iBUS2 sensors won't work on the secondary RX, even connecting the two RXs via iBUS2. The secondary RX can only be configured to S.Bus, iBUS-OUT XOR iBUS2, besides PWM and PPM of course. No iBUS-IN option. So FlySky wants you to do away with the iBUS sensors in favor of their new iBUS2 ones. What a shame. Fortunatly the old iBUS sensors still work with the advanced RXs, by themselves, with .

It's because you can only have one ibus protocol on the tx at a time :)

[@klausmewes3622]

@@WTFRCCars FS should have thought of this when they developed the iBUS2 protocol. Unless they intended to force us to AFHDS3 and iBUS2 and abandon our older technology and invest AGAIN in their new one. Shrewed business practice. But we are suckers and they know it.

While I do like these new and overall smaller sensors, I do see some potential flaws. For starters, as of this typing I can buy the current available sensors for as little as $8 a sensor. Don't know how much more these newer ones will cost as of this posting. Also the older sensors, as you noted, can be "piggybacked" with just one of the sensors having to go into a RX channel. Now you will HAVE to buy the CEV04 module do that, if it's even still compatible. Note as well that only with the enhanced receivers can one set the individual channels to specific outputs unless something changed that I'm not aware of. I'm not sure if iBus2 has faster data transfer rates or what but for me, I'm keeping what I currently use which is mainly, the now older, temp and voltage sensors.

[@WTFRCCars]

Yeh will have to have a good look at how best to use these but as of now I can only find them listed at around £40 each which is crazy price increase if that is what they retail for.

@@WTFRCCars $50!!?? I may as well buy Futaba gear then. Unreal if that's true.

[@WTFRCCars]

I thinks it's just early sellers trying to cash in

[@klausmewes3622]

The iBUS and iBUS2 are mutually exclusive, you can't use both in the same setup. THe iBUS2 transmission rate is 10x that of the iBUS, BUT telemetry data is sent back to the transmitter every 10 data/control packets received by the RX or even less frequently. So what would the higher transmission rate be useful for? Not for telemetry but for servo control if you connect iBUS2 servos. Than again is that really practically necessary?

[@WTFRCCars]

Ibus2 servos work really well I run them in the touring car

[@Larfinkle]

Very nice size! Does the GPS work for nb4??

[@WTFRCCars]

No nb4 has no GPS function

[@PcItalian]

Will this work with the flysky FS-G7P?

[@WTFRCCars]

These require ibus 2 so unless the G7P has Ibus 2 then they won't work with it but I'll have to check

[@WTFRCCars]

Hi I have checked but no the G7P can not do ibus 2 so only the older type sensors will work and not these on the current firmware.

[@albertkelly7129]

Nothing about these sensors makes any sense. They are obscenely priced [about 5x the cost of the older sensors!!] and in fact only cost slightly less than the GPS module/multi sensor! Further they've lost the piggyback function, the cable looks to be extremely short and they dont do anything new or better than the older sensors do. Every single thing is worse. Something Im missing here? lol

[@WTFRCCars]

The sensors do far more than the old ones and have much higher data transfer bandwidth available, they also don't affect the latency of the radio and are designed to connect through the ibus 2 connectors so don't need daisy changing hope that clears things up a bit, also think the prices will be cheaper when the availability goes up as it looks like the 1st sellers are trying to up the price :(

[@klausmewes3622]

@@WTFRCCars Telemetry data is sent back to the TX at a 1:10 ratio every 10 control packets received the RX sends back a telemetry packet. So only if the RX has a MPU and analyzes and uses the data for calculation and stores the results in RX memory will that be useful.

[@WTFRCCars]

@klausmewes3622 the telemetry updates many time a second even with multiple sensors running including the GPS module the Rx doesn't do any calculations with the ibus 2 data
