The FrSky RB-40 allows the use of 3 FrSky receivers, stabilization, built in telemetry, dual batteries and much more!

The FrSky RB-40 is the next major leap up from the RB-30 it allows the use of 3 FrSky receivers, stabilization and 2 batteries, giving you total peace of mind when flying your R/C aircraft.

The RB-30 also has a built in gyro, allowing you to have stabilized flight. The stabilization can be configured via LUA or the FrSky S.port Airlink+ combined with either the Freelink app or your computer. Turn it on or off and fine tune the values from your FrSky radio or with the newly added LCD screen and roller.

It also has other diversified telemetry feedback such as voltage, power consumption, altitude, and more. Other features include a Flight Data Recorder (Black Box), dual 30 amp SBEC outputs (from 5 to 8.4 volts) and a contactless NFC power switch.
