Fly Boy 3 Posted May 5 Share Posted May 5 Hi all, Cannot find suitable info on how to do a range check on this radio other than a long walk. Has any have a better idea ? Also what is actually meant by “full range”. Thank you. Quote Link to comment Share on other sites More sharing options...
Phil Green Posted May 5 Share Posted May 5 (edited) A long walk is the only real way to check any R/C set, low-power 30 pace checks prove very little and can even give a false confidence. I range test at night, have a channel indicator with superbright red & green leds that can easily be seen over a mile away. https://www.youtube.com/watch?v=S0VMsjXb2iA Edited May 5 by Phil Green Quote Link to comment Share on other sites More sharing options...
Fly Boy 3 Posted May 5 Author Share Posted May 5 WOW, what a great idea Phil. Distance is the key. I don’t know about a channel indicator, but I could easily set up a led and battery circuit and clip leds to control surfaces in turn. Thank. You.

GrumpyGnome Posted May 6 Share Posted May 6 I think lots of FlySky stuff sends the voltage at the rx back to the tx, and displays it on screen. Switch your model on, walk away and check that it's displayed - if it disappears, you're out of range..... Quote Link to comment Share on other sites More sharing options...

Receiver to transmitter range isnt the same thing, telemetry sent at a much lower power level 🙂 Quote Link to comment Share on other sites More sharing options...
GrumpyGnome Posted May 6 Share Posted May 6 I know that's true for Spektrum, but didn't know it was the case for other brands... live and learn! Quote Link to comment Share on other sites More sharing options...
Robin Colbourne Posted May 6 Share Posted May 6 I had this problem when I took a FlySky FS-i6 to our club for the first time and wasn't allowed to fly. The site rep was adamant that I would need to do a range check, so on the next visit we did a full range check, before other flying started. This was my report to the committee following the test: "...we conducted a full-power range check of my FlySky transmitter & receiver. This demonstrated the range at approx 6ft off the ground to be as shown in the photo below. The distance quoted is by scaling from Google Maps, so should not be considered especially accurate. Transmitter: Flysky FS-i6 2.4GHz Transmitter Battery Voltage: 6V Receiver: Flysky FS-R6B Receiver Battery Voltage: 6V Transmission Protocol: AFDHS (Automatic Frequency Hopping Digital System) This is FlySky's original protocol, not the later AFDHS2A Weather Conditions: Dry Grass Length: 300 to 400mm (12" to 16") Test Result With the transmitter and receiver located in the positions pictured below, the model functioned normally with the transmitter at head height, however the signal was intermittent with the transmitter held at waist height. Given the grass length and its moisture content, this may have attenuated the signal. The model was supported off the ground for the tests. The test was repeated with the receiver aerial side on and end on. Controls (Ailerons, Elevator, Throttle & Rudder) were tested individually, then all together. Conclusion: The test was considered a pass. Quote Link to comment Share on other sites More sharing options...
Paul De Tourtoulon Posted May 7 Share Posted May 7 I am surprised at this test being needed, especially as the club's grass was obviously too long therefore 'non conform',,,😂 Quote Link to comment Share on other sites More sharing options...

That's mental that they just stopped you flying - the FlySky stuff is CE marked (I had to look it up to be allowed to fly at Shuttleworth on a model weekend).

Its a military airfield and the club do tend to be cautious as it wouldn't take much for us to lose the very good site. I was pretty peeved at the time, as I had just changed from Spektrum, as satellite receivers are mandatory on them in the club, and it that was a whole load of extra expense I didn't want. Anyway the full-range check did give me some peace of mind, as, with ground attenuation taken into account, the range in the air must be pretty good.

I started off with FlySky, and still have two for buddy boxing with my kids. The only problem I've ever had with them, is the AA batteries - do not take off if it's showing half on the "battery-o-meter" on the main screen. I was lucky the one time I got caught out, and I was flying a free flight/RC conversion that happily landed itself not too far away. Range is fantastic, reception is fantastic, the voltage sensors for your electric planes are brilliant. If it does everything you need it to, you've definitely got nothing to worry about. 👍 Quote Link to comment Share on other sites More sharing options...
