This also gives automatic real-time telemetry of the main battery voltage, which allows longer flight times.
Given how well the Hitec system has been working, I am now putting BECs only on my larger planes where I expect lots of servo load.
That's cool Reegor
It was a decision between Futaba and Hitec and at the last minute I went for Futaba as the Hitec RX antenna kind of put me off. Petty I know
However. I only use 6 channel units so no major funds needed.
If the Futaba system works OK I'll hang on to it but may consider a hitec unit in the future. I really like their features even on the 6 channel TX.
It has everything there as standard for crow braking on the SSS.
