Wouldn’t it be good, if you could train FPV flight with a flight simulator on your compuer, using your actual transmitter (in this case the FlySky i6) as controls?
Most instructions explain how to do this by soldering a cable with a trainer port (S-VHS) to 3.5 mm audio connection. Instead if building a specialized cable, my DIY guide will explain how this can be done achieved by adding an audio jack directly to the transmitter, so you can use a standard audio cable (which you might already have).
I am trying to build up my multicopter skills step by step, before jumping all in into high speed FPV flying and crashing my first expensive drone. For that reason I currently practice with my micro FPV indoors. It’s an Eachine QX95 which I like a lot and modified a little. I also read up on the technical (I might want to build my own drone sometime later) and “howto fly” side of things.
My then extensive work of getting everything up and running resultet in:
I finally found out what I was doing wrong all along, in an utterly insignificant little blue-green forum comment in the uncharted backwaters of the unfashionable end of the western forumsphere of the internet:
Umm – I should be switching it to student mode?
Thank you Spartacus Rex, thank you!
I spare you further details of the production mishaps. What follows is the diy instruction for successfully getting the FlySky i6 (Eachine i6) connected with a FPV simulator, using a 3.5 mm audio cable.
Flysky i6 modification to connect with computer via 3.5 mm audio cable
- a 3.5 mm audio socket (e.g. like these)
- a 3.5 mm male-male audio cable (long enough to reach from your transmitter to your PCs mic input)
- two thin wires, 15 cm each should suffice, for wiring up the jack inside the transmitter
Actually, I had all of the above just sitting somewhere in boxes and little drawers of my collection – lucky me :-).
- soldering equipment
- Philips screw driver
Step by step instructions
1. Remove all batteries from the TX (better safe than sorry…)
2. Unscrew the transmitter (four Philips screws at the back)
3. Fully separate the two parts (the “front” with all the controls) and the “back” with the battery compartment and trainer port). In order to do so, pull the two white plugs – the one connecting the batteries and the one connecting the trainer port.
4. Drill a 6 mm hole into the back part. Choose a place where the 3.5 mm audio socket will have enough room once it is fastened in place and the transmitter has been put back together. It should not touch any other component.
For me, the best place I could find for my jack was in the lower left hand side, inside that little “foot” that is on the bottom:
5. Solder two wires to the audio jack:
- the “signal” wire (mine is red) goes to the connection for the tip of the audio plug
- the “ground” wire (mine is yellow) goes to the connection for the sleeve (the very back) of the audio plug
6. Fasten the audio plug in place. For me, this included shaving off parts of the plastic housing, as it would not sit flush against the inside of the transmitter casing otherwise.
7. Now solder the wires to the soldering points on the circuit board of the trainer connector. As you can see, FlySky generously provided us with big soldering points. So we should really make use of them! Before soldering, cut the cables down to a length where you have just enough to lay it down flat inside the back of the transmitter.
8. Tape down the full length of the cable. We want to minimize the chance, that something goes loose and interferes with the transmitter just when we try our first loops…
9. Re-plug the back part and screw everything back together.
10. Haha – did you really tape the cable down and put everything back together without testing your setup or at least reading all the steps first? You really should have!
8. (For real now :-)). Plug your audio cable (male-male) into the new socket which you just installed. Use the continuity check feature to ensure, that:
- there is a connection between the tip of the audio plug and the soldering point with the signal cable
- there is a connection between the sleeve (the conductive part furthest away from the tip) of the audio plug and the soldering point with ground cable
- you cannot find any other connections between soldering points and the audio plug
Also check, that with the batteries back in, the transmitter works as expected.
9. Now tape down the cables and put the transmitter back together.
10. Install SmartPropoPlus and run it.
11. Connect your transmitter to your microphone audio jack of your computer.
12. Set your FlySky i6 to student mode. In order to do so, hold both horizontal trims inwards while powering on the transmitter. Then press “ok” for a second and the menu will pop. Finally select “Student mode”, which is part of the “System” menu, a few clicks down.
At least, that’s what I hope you achieved. There are (as always) a few things which can go wrong. On the SmartPropoPlus website there is a really helpful section about setting up the system correctly.
I keep my fingers crossed, that your project turns out well and that you will feel pleased with what you accomplish.
If not, I can recommend the sources I am giving below, at least they were helpful to me when I did this.
You can also contact me via a comment and I’ll try to help as good as I can.
