Set-up of
FlySky FS-i6/FS-i6X Transmitter (Tx) and FS-iA6B Receiver (Rx) for
RC Racing Yachts
(David Flakelar - Sydney)
Background
These notes are written to help the beginner set-up the FlySky Tx/Rx system to operate with the
DF65 and 95. There are also a few tips in an appendix that have nothing to do with the FlySky
system but may provide some useful background.
Any feedback would be much appreciated.
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.

Why I Bought the FlySky TX/Rx System
1. It appears to be used by most of the fast sailors!
2. In Australia, the marginal cost is around $20 compared to the Joysway model for many
more useful features. (The cost of FS-i6 system less cost saving on buying the kit without
Tx and Rx). At current Hobby Warehouse prices this represents an extra cost of ($76 -
($237-$179)).
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 for Rx battery can be set.
5. Expo (exponential) and or proportional control can be used on rudder and winch
movements.
6. The same Tx can be used with several Rx.
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?
FlySky Product Range
The DFs require 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. There are two Rx types - the iA6A is a lightweight
receiver generally not suitable for a marine environment with an exposed circuit board, while the
“B” version has a more protected hard plastic case.
The supplied Rx from HWH 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 with the black/brown cable on the
bottom. 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.
Instruction Manual
A 32-page Instruction Manual is available from the web. Search “FlySky FS-i6 manual”. These
notes should be read alongside the manual which is incomplete; while some functionality is not
explained. I have given my interpretation but this may be inaccurate and if I err please let me
know.
There are several of videos about the FlySky system used with RC yachts available on YouTube.
Most others relate to control of model aircraft. Search on “FS-i6/RC yachts”.
