I got this after asking ChatGPT 5: 🔑 1) ELRS Channel Resolution By default, ELRS sends CH1–CH4 at full resolution, and CH5+ at reduced resolution when Hybrid Switch Mode is enabled. That’s fine for quads and switches, but not for helicopters, since you need full resolution on both throttle (CH3) and collective pitch (CH6). Solution: In the ExpressLRS.lua menu on your radio, set Aux Channels → 8 Channels (Full resolution). This makes CH1–CH8 all high-resolution, smooth enough for pitch curves and throttle curves. Without this, CH6 will “step” instead of moving smoothly. 🔑 2) CH5 is not an “arming channel” in ELRS The idea that CH5 must be used for arming and affects RF link quality comes from Betaflight/quads, not helicopters. ELRS itself doesn’t require CH5 for RF arming. The link is always at full performance as long as the TX and RX are powered and bound. On the Goosky S1, CH5 is used by the flight controller for flight mode selection (Pose/3D/Rescue, etc.). Assign CH5 to a 2- or 3-position switch on your radio. Adjust endpoints so that −100/0/+100 line up with the S1’s mode LEDs. 🔑 3) Channel Mapping for the S1 Legend Typical setup in EdgeTX/OpenTX (Pocket, Zorro, Boxer, etc.): CH1 = Aileron (Roll) CH2 = Elevator (Pitch) CH3 = Throttle (with throttle curves and throttle hold switch) CH4 = Rudder (Yaw) CH5 = Flight Mode switch (stabilized / manual / rescue depending on firmware) CH6 = Collective Pitch (with pitch curves on the same stick as throttle) Important: set swash type to H-1 (1 servo, no mixing) in the radio. The S1’s internal FBL handles swash mixing. 🔑 4) Wiring & Telemetry The New Edition S1 Legend has a 4-pin JST-1.25 ELRS port. Plug your ELRS receiver (or the internal module if it’s built-in) into that port — it carries power, ground, CRSF protocol, and telemetry return. Telemetry includes VBAT (main pack voltage) and a calculated battery %, sent back to your ra

It looks like your only option is ELRS V4 (WIP) and EdgeTX 2.11+ (released) as it lets you decouple arming from Ch5. PS I am in the camp "Thou shall not reinvent the flight controller" and IMHO everything should run Ardupilot or other flavour of open source flight controller firmware.

Just remap a model inside your radio with the channels matching what you want like how you would if you didn't like the factory chan5 switch being arm for your drone. A simple seperate model in the radio would solve everything (having said that I been using chan6 for arming my drone on my rm pocket and haven't really had any issues

To get the "jumpy values" fixed you need to change to the 333hz on the express elrs script!

There are already a number of Goosky/ELRS videos on YT? None of these any good?

Can you help? I've got this Goosky S1 Legend in to look at (it's the latest version that has the ability to be used with ExpressLRS!), but can't find any documentation that covers how to setup the radio and configure it for that.
Non of the videos I've watched address a number of key issues using ELRS.... CH5 is needed for ARMING ExpressLRS meaning that using that for a control for the Heli is a bad idea as in the LOW position ELRS is 'sleeping' and range and link performance is affected.
Plus, ELRS only sends the first 4 channels as 'full resolution' by default so using CH6 for pitch means that the pitch doesn't move smoothly but will 'jump' from value to value as the throttle moves - far from ideal.
Do you know where I can get the detail I need to setup ELRS well with this model? I've emailed Goosky as well...
(Goosky really need to work harder on their manuals for this stuff!)
