The OrangeRx SF400S has all the properties and features of the original FASST compatible receivers in the OrangeRx brand but this one now operates on the later Futaba FHSS (Frequency Hopping Spread Spectrum) system. This receiver has 2 operating modes, Mode A gives the standard 4ch operation, Mode B gives CH1, CH2, CH3 and SBus.
The S.Bus functionality is an excellent feature for use with multi-rotor flight controllers such as the KK2.1, APM, MultiWii and others. These single line connections remove the weight and mess of additional wire leads for each individual channel. This is ideal for use on small frames where space is at a premium and keeps all the wiring neat and tidy.
The receiver will also accept a wide range of input voltages from 3.5~8.4V which is great if you want to use LV and HV type servos.

I used this SF400S Rx on a 180 size miniquad in S.BUS mode with My Futaba T8J radio and was getting a lot of brownouts during flight. Mostly while doing quick flips and rolls. Sometimes the Rx would reset quickly while in forward flight and my quad wouldn't crash but you could definitely feel you had no control over the model for a second or two. Other times my quad would go straight into the ground! Antenna was placed nice and high on the end of a zip tie about 4-5" off the frame so that wasn't the issue. One particular time I was showing a friend how to do quick flips literally 6' in front of me about 15' in the air when it browned out while inverted. It sent my quad straight into the ground at almost 3/4 throttle. :( I also purchased the SF700S which is the 7ch Diversity version of this Rx and the same brownouts would occur but less frequently. And it had a little better range. That Rx was on a 230 size miniquad and also running in S.BUS mode. I went back to my original 8ch Futaba FHSS Rx and all the brownouts went away. Super long range also.Small and light.
I try on distance up to 300 meters on ground - work perfectly.
Good for Hummer EPP 3D
My transmitter - Futaba 8J.Utilis avec une T8J, je n'ai pour l'instant aucun souci mme si je manque de recule.
