Receiver compatibility for your particular radio system can also be a feature to look into. All FBL systems will support standard wiring connectivity methods of course, but many of the better flybarless units are also Spektrum Satellite, SBus (Futaba & FrSky), Jeti EX Bus RX & Mikado Touch Control compatible these days. This simplifies wiring and makes for a "neater" install.
Make no mistake, flybarless systemsare considered the "heart of the heli" these days. Next to setup, theyhave perhaps the single largest impact on the response and behavior of a modern day RC helicopter. It's hard to know which you will like the bestin other words as so much is "feel" dependent.
MSH Ikon(also branded as MSH Brain) out of Italy has been one of the most sought after flybarlessstabilization units on the market over the past decade now, being Futaba & FrSky SBus, Spektrum DSM2/Xremote (satellite), and Jeti EX Bus receiver compatible. It's alsoone of the best value, higher end units currently on the market rightnow in my opinion.
Like all the higher end FBL systems listed on this page, the MAXX ASG flybarless flight controller offers multiple modern RC receiver connectivity options (S-BUS/JR-Xbus/UDI/SRXL/SRXL2/SPM4649T/DSM/ExBus); but doesn't support standard RX connectivity (PWM) so if you run an older radio system, pass on the MAXX ASG.
What can I say - I love Bavarian Demon's FBL systems. I currently usetheir 3X units in my Trex 700E BlackShark, Bergen Intrepid turbine, Roban 700 Super Scale AS350 & Roban 800 Super Scale EC130. It'shands down the best flybarless system I have flown to date based on my flying style and the overall feel.
Their older X-series is a purehi-end meat & pototos flybarless system with no self level or rescue feature. It works really well in big scale helicopters & turbine applications, but is also a decent 3D performer while supporting all swash types and multi bladed heads for the scalecrowd.
I'm fairly certain all the new systems with high sampling rates like the new Bavarian Demon Axon, Ikon2, Futaba CGY's, VBar NEO, MAXX and Spirit are safe turbine choices as well; but if you fly flybarless turbine; definitely double check with the manufacturer to make sure their system will handle the ultrasonic frequencies produced by the engine.
Futaba has for decades made some of the best RC helicopter tail gyros on the market. It's all I used to fly with. With the advent of flybarless, it only makes sense Futaba also have some of the best flybarless systems on the market.
Futaba's two latest flybarless systems include the CGY755 and the CGY760R. The main difference between the two is the 760R includes both T-FHSS & FASSTest protocol built in receivers, whereas the 755 doesn't.
Quite a few RC heli pilots passionately feel the VBAR is the best flybarless system out there "bar" none (pun intended). Their NEO series of FBL units will also communicate fully with Mikado's line of VControl radios.
This allows you to use the setup wizard direct through the radio to the flybarless unit meaning no laptop or smart phone is needed for FBL setup. Parameters can even be changed on the fly through the radio along with firmware updates. For some, this direct radio to FBL unit programming and configuration is very convenient.
The MicroBeast Plus & MicroBeast Plus HD by BeastX (again out of Germany) isanother FBL system that many pilots consider to be the best flybarless system currently on the market from an ease of use/programming standpoint for newbies. I agree with that.
As I already mentioned, I personally feel it is one of (if not the) best flybarless system for people's first introduction into virtual flybars due to itsout of the bag plug and play simplicity along with easy to understandsetup instructions & intuitive LED programming method direct on the unit.
Spektrum teamed up with BeastX, offering theirAR7210BX 8 channel receiver which is essentially an 8 channel DSMX Spektrumreceiver with the MicroBeast flybarless system built in with provision for oneadditional satellite Spektrum RX.
For about $200 USD new and half that used, the AR7210BX is still a great value option if you fly witha Spektrum, JR, or multi-protocol DSM2/X radio and want to get a combination RX and flybarless stabilization unit to save a little money over getting twoseparate components not to mention make for a cleaner and simplifiedinstall.
Other proprietary Spektrum/Blade/Horizon Hobby connectivity technology includes Smart (ESC & Battery), Spektrum telemetry, and forward programming of the flybarless flight controller through compatible Spektrum radios (transmitters).
A good FBL flight control system for Spektrum only users, but due to it's proprietary Spektrum/Blade/Horizon technology, not the best flybarless system for users of different and more cost effective alternatives.
They have 3 different flybarless systems to choose from based on your particular needs from the tiny uSpirit that will work with 130 to 250 size helicopters, up to their newest Spirit 2 that will work with 250 to 800 size machines.
As you can see, the continuing trend and holy grail offlybarless stabilization right now is to create systems that respondwith the predictability and consistency of a flybar, yet give that"tracking on rails" flight experience.
Finally and if you are an FBL newbie, consider what specific flybarless / flight controller system/s are being used in your area or flying club (local familiarity in other words). Using a system that is popular in your area or club has the advantage of getting experienced setup/tuning help should you need it.
