FrSky does not sleep, or rather woke up, and after years of not touching the topic, released an “important” update of ACCST 2.4GHz protocol for all the compatible 2.4GHz receivers, transmitter modules, and radios: X9D Taranis, Q X7 Taranis, X10/X10S Horus, X8R, X4R, X4R-SB, XM, R-XSR, XJT and so on.
What changed in ACCST 2.0.0? According to FrSky, they fixed some kind of a bug with uncontrolled servo movement in ceratin conditions (probably almost never) and improved “correction and verification”.
What does it mean in the real world:
- ACCST 2 is not compatible with previous ACCST
- if you decide to upgrade, you will have to upgrade receivers and transmitters. All!
- any 3rd party ACCST compatible receivers and transmitters stop to work: including multiprotocol modules and 3rd party D16 receivers
Consumer advise? Do not update! There is no need to update from ACCST to ACCST 2.0.0. Looks like there is no gain for end users at all and the cost is substantial!
