Set-up of
FlySky FS-i6 Transmitter(Tx) and FS-iA6B Receiver(Rx) for
DF65 RC Racing Sailboat
(David Flakelar)
Background
The FlySky FS-i6 system operates under the Digital Proportional Protocol using an Automatic Frequency
Hopping Digital System. It is a pulse digital system on carrier frequencies unique to a particular transmitter.
You don’t need to know how that works. The manufacturer claims there is no risk of interference from
another transmitter.
These notes are written to help the beginner set-up the FlySky Tx/Rx system to operate with the DF65.
There are also a few tips that have nothing to do with the FlySky system but may be of interest.
Feedback would be much appreciated.
Why I Bought the FlySky TX/Rx System
1.
It appears to be used by most of the fast sailors!
2.
The marginal cost is the cost of FS-i6 system less cost saving on buying DF65 without Tx and Rx. At
current Hobby Warehouse prices this represents an extra cost of (76.4-(237-179)) which is $18.
3.
Minimal risk of interference from other sources.
4.
Using its built-in telemetry capability, the condition of both batteries is displayed on Tx monitor.
Visual and audible alarms can be set.
5.
Expo (exponential) and or proportional control can be used on rudder movements
6.
Winch action can be desensitised
7.
Using Dual Rate alternate rudder settings can be established.
Compatibility
The FlySky Tx will only operate with a FlySky Rx of which there are several types. The Turnigy and Park
Fly products appear to be FlySky re-badged?
Instruction Manual
A 27-page Instruction Manual is available from the web.
On registration with Gearbest, a slightly larger FS-i6 manual is available. Some DF65 packs come with the
manual on a disc.
There are a number of videos available on YouTube. Most of these relate to control of model aircraft.
Search on “FS-i6/DF65”.
Switching Sequence
Having assured the user there is no risk of interference from another radio frequency source, the maker
recommends that a particular switching sequence be observed, which is: Tx ON, Rx ON: Rx OFF, Tx OFF.
FlySky Product Range
The DF65 requires only a two channel Tx to control rudder and sail winch.
The FS-i6 is a 6 channel controller and the FS-i6X provides 10 channels.
The supplied Rx is the FS-iA6B with 7 ports and for neatness the three cables (battery switch, rudder and sail
winch) plug-in horizontally from the end. A FS-iA6 Rx is available and has the same functionality but the
seven ports are arranged vertically with exposed pins. Depends how you want to arrange cabling.
FlySky Operational Range
The physical range of the FS-i6 is dependant on the condition of batteries, orientation of both Rx and Tx
antenna ie. the way the Tx is held. The Rx has two antenna and their orientation should match the
manufacturer’s instructions. However, range should never be a limiting factor for DF65s. The FlySky
system has been shown controlling a drone out to 2.3km.
