Copter-3.5.1-rc1 (release candidate #1) is available for beta testing through the MP’s “beta firmwares” link.
This version has only a single fix on top of Copter-3.5.0 (ReleaseNotes are here).
- fix to RC input corruption when using Spektrum DSMx with Pixracer
The solution was to re-enable DMA (direct memory access) on the Spektrum port. You shouldn’t notice any real differences from 3.5.0 but moving DMA channels around is a fairly low level change so any testing people can do is greatly appreciated, thanks!
If all goes well, we will release this as the official Copter-3.5.1 in about a week.
