Got some new receivers in that are compatible with the FrSky protocol. No doubt thanks to midelic’s work on RCGroups. Hoping the sqaurish format will allow me to bury it into micro FPV quadcopter builds. It was difficult finding a location for the regular FrSky X4R-SB.
I will be updating it with the new firmware versions midelic made available. Linked to below. It now supports telemetry and PPM and SBUS.
Some pictures of the RX-801 as I took off the outer plastic casing. The F802 came in a similar case.
