Here is a copy of Rick's post from facebook:
Hi guys. We would like to thank you all for your support and feature requests for Smooth Flite system. Our team have listened to you and have added many new features.
The new version 5 firmware is available now and all new Smooth Flite units will be shipping with V5. All existing Smooth Flite units can be updated to V5 with the AR updater cable. Contact us via PM if you need assistance with the update.
The new Smooth Flite version 5 user guide is now available from the Smooth Flite product page at boomarc.com so please download and enjoy.
In the next few days we will be shooting video showing the setup of the advanced features found in the new version. These videos will be available on our YouTube channel accessible via the Smooth Flite product pages at boomarc.com so stay tuned.
OK, so here are some of the new features we have added.
NEW PROTOCOLS
We have added in SBus protocol and Sport telemetry for FRSKY. So, Smooth Flite now supports Futaba SBus2, JR/DFA XBus-A, FRSky SBus, Spektrum SRXL, Spektrum DSMX, Graupner HOTT, Multiplex SRXL, and Jeti EX Bus. With support for all major industry protocols Smooth Flite is now the most supported vendor neutral product available today.
NEW MIX FUNCTIONS
* We Implemented separate Elevons and V-Tail dual channels so in conjunction to Ailerons, Elevator and Rudder You now have separate elevon and V-tail channels all with Smooth Flite Gyro control. We are flying our 3 meter Rafale and SU37 with these new elevon function. Many Mephisto owners will also love the ability to have gyro assisted elevons and separate aileron control.
* We implemented gyro assisted Flaperons and Crow function with speed control so you can now assign Crow or Flaperons to any input control channel to offset ailerons up or down. You can use a 3 position switch or any channel like for example the flap channel. The choice is yours.
* We implemented gyro assisted Rudder brakes function for dual rudder models. You can assign a rudder air braking position to an air brake switch or perhaps the ground brakes channel all with gyro assisted steering. The choice is yours.
* We Implemented Vector thrust switching on up to 4 output channels. This function works with single turbine vectored thrust (elevators and Rudder) or dual turbine elevons configurations where you can switch thrust vectoring ON/Off via a transmitter switch.
* We Implemented Gyro assisted Steer trim so pilot can adjust steering trim from TX.
* INDUSTRY FIRST - Weighted Mix Elevon mode (averages Elevator and Aileron to 100% of throws based on user selectable scaling). This is good for elevon models like the Mephisto where nice axial rolls are a required.
* Implemented Non-Weighted Mix Elevon mode (Uses 100% of Elevator and adds user selectable 0 - 100% of Aileron). This function is good for military scale models like the F18, Su27, Su35 etc where ground presentation is important at scale competitions. It gives very real elevon movement and still retains the Smooth Flite gyro assistance in the air. Also great for real nice barrel rolls.
* Implemented Weighted Mix V-Tail mode (averages Elevator and Rudder to 100% of throws based on user selectable scaling). This gives V-tailed scale models a nice flying characteristic.
* Implemented Non-Weighted Mix V-Tail mode (Uses 100% of Elevator and adds user selectable 0 - 100% of Rudder). For guys flying V-tailed models requiring scale like ground appearance then the non weighted mode will achieve this.
* Added output channel travel limit for all 26 servo outputs. Some of the new functions like weighted elevons and V-Tail allow for the experienced modeller to over drive servos beyond limits when achieving scale looks. The travel limit can be set for any of the 26 servo outputs remove possible servo overdrive.
* Added pronounced bump function at start-up if gyro switch is activated. This was added so the pilot positively knows when the system has finished calibration at power on. It is important to have the gyro in the low or high gain position when powering up the Smooth Flite.
* Increased Gyro processing speed so Smooth Flite now reacts 200 x faster than your fingers for even Smoother Flite.
NEW USER INTERFACE
With version 5 you will notice many of the GUI pages have been updated so it is now much easier and faster to program all Gyro and channel Sub Trim functions via the full color touch screen.
So... download the version 5 User guide and enjoy the worlds most advanced gyro assisted flying system for RC models.
