Best detailed video setup for the Kopilot Lite with a ZOHD Talon EVO and Radiomaster TS16 Transmitter

[@davidlumgair3499]

Best explanation I've seen thanks, I have an issue if you have time, when I input into the sticks there is a massive delay for the plane to react, I'm talking ten seconds sometimes, I'm using a frsky r9sx receiver sbus

[@danniecarmona2509]

Thank you very well explained for newbies like myself.

[@peterkoslowksi4462]

Thank you so much for detailed Installation guide! 👍 I bought a Kopilot Llite together with a Zohd Drift. Unfortunately, I‘m having big problems getting a connection to the Kopilot. I‘m using a Crossfire Nano + Taranis QX7S + Crossfire module. The Connection between Crossfire Nano and Crossfire Module seems to be fine (solid green light). I‘ve created a simple 4 Channel model in my Taranis and added a 3 way switch as channel 5. For the transmitter output, I‘ve selected external and Crossfire. With this setup, no input reaches the Kopilot. The Kopilot is permanently in balanced mode (flashing green light). I can select different plane types using the set button of the settings board in this mode, but this does not solve the issue. Surprisingly, this setup worked before I played around with small settings board. It seems that - by accident - I‘ve messed something up within the Kopilot. Is there factory reset for the Kopilot available. Can you provide some hints for troubleshooting this issue? 🧐

[@bonafidepirate]

It's been a long time since I used the Kopilot, so I may be missing something... lol The only thing I can think of right off hand would be to make sure the Crossfire receiver is configured to output SBUS on whatever signal pin you connected to the input on the Kopilot. (They're set up for CRSF by default) Apart from that, everything else should be the basics covered in the manual.

[@EnglishTurbines]

Good job m8...I like that screen on the T16...No wonder FrSky went ape over it.

[@bonafidepirate]

I think it's the same screen that's in the X10. I like it too. I'm really looking forward to some coming updates, OpenTX should have native support for it in 2.3.2 release according to some of the devs, and a merged pull request. ;) The JumperTX fork isn't bad, but there's always that question in the back of your mind, will they keep updating it so we get all the new fixes and features... lol This is shaping up to be a heck of a radio! Jumper just released an internal multi-protocol module for it too. I have one on order, even though I rarely use the 2.4 modules. I did use the external multi one to fly a little indoor heli recently just for fun, it's pretty neat! Way more fun that flying it with the toy transmitter it came with.

Thanks for the informative video, as usual very well presented easy to understand. I hope you can help me with a problem I am having with my new Kopilot Lite autopilot system. I have it installed in a flying wing and set up via sbus from my RX. I am unable to set up the Neutral Calibration by the sticks on my mode 2 Taranis TX. Nothing happens with the LED lights. No flashing. I was in stabilised mode as per the manual. The radio calibration was successful though. All other functions and set up is correct and working. Many thanks Mike

[@martincloutier1399]

Did you find the solution ? I have the same calibration problem.

[@wad5uk]

@@martincloutier1399 Hi Martin The problem was me. I had programmed the stick throws (travel) or Rates(weight) on my Taranis to be about 70%. So when I pushed the sticks to an end point the travel was not 100%, just 75& which was not far enough for the KoPilot to recognise. Once 100% travel was installed back it worked. So now on my 3 position rates switch the top one is as 100% travel and the other 2 switch positions have rates and expo programmed. Also for some reason my elevator trim switch is now reversed with this set up. A bit scary on the maiden as when I put up trim in it dived further. I just have to remember that if I have to re-trim. I see others have had the trim problem with, Strange. Anyway, hope that helps. Let me know how you get on. Bonafiedpirate has a good KZbin video on set up.

Hey man Im a huge fan of the channel, just wanted to let you know lol your videos have made me fall in love with fixed wing FPV, especially semi-autonomous flight... I run a small UAV business doing small scale mapping and videography work mostly but next spring I am looking to invest in some fixed wing mapping equipment in order to cover larger areas for mining and exploration companies in my area (Yukon, Canada). As a pet project I was going to try to turn one of these into a backpack sized micro-mapping platform over the winter using ardupilot on an omnibus f4 board or a matek f405. The idea is to try to fit a gopro into the nano talon and use Pix4d to generate preliminary maps from the images captured by the gopro.. On the website for this airframe it seems to allude to a small "camera bay" on the bottom of the aircraft. In your opinion do you think there is indeed enough room in there to fit a hero 7 or equivalent in a downward facing position?... Any advice is greatly appreciated, thanks man!

[@bonafidepirate]

There's actually an optional mount available for the Hero7 that fits into the bottom bay specifically for that reason. I haven't done any mapping before and wouldn't know where to start, so I can't say how well it works. Look at about 8 minutes into this video - kzbin.info/www/bejne/g4fHqqJpnpZ7rKM

Hi! Great video. Questions: 1. My wing flies well in normal mode. It flies also well in stab mode but I have almost no control in this mode. The travel of Ail and Ele is much less in this mode, almost nothing. Why? Using a frsky taranis q7. 2. For the throttle to work on my controller I have to inverse it (weight -100 on Taranis). Why? 3. I cannot calibrate the plane (sticks inside and down). The green leds won't flash after 5 seconds. Thanks.

Keith when I connected the throttle cable directly to the ESC and bypassed the Kopilot, it works fine. The other servos and modes are working off of the SBUS connection. Does this mean I likely screwed up in my Tx setup?

[@bonafidepirate]

The setup in the transmitter is probably fine if it controls the ESC directly with the receiver. Double check that you're in manual mode, the throttle won't work in the other flight modes before GPS is locked, and still won't run up in RTH with a lock until the plane starts moving. After GPS is locked the throttle should work in stabilized mode and manual.

Thank you Very good tutorial did you use the jumper tx for your one hour video

[@bonafidepirate]

Yeah I did, so far I've flown the Esky Eagle and this Nano Talon BO with it using the R9M. I like it so far. The firmware is a little messy, but OpenTX has merged a pull request and will support the T16 natively (no need for the JumperTX fork) starting in the next release. It should be in 2.3.2, and probably 2 or 3 months out based on what I've seen from the devs that post on RCGroups. I'll probably wait to transfer more of my planes over after that.

Keith, did you see anything in the manual about Spektrum channel layout as in T,A,E,R?

[@bonafidepirate]

No, as far as I know it needs AETR on 1234. I'm not farmiliar with Spektrum radios, but can you remap the channels where you want them? You could probably change the wiring in the PWM input connector to put each signal where it needs to be. Just mark them before pulling them out of the housing, then put them back in so each input matches your receiver's output pins. sbus would be a different story though, that would need to be mapped right I would think.

Maybe I missed this but does rth also work on failsafe? If not I do not get the benefit of having gps. Also seems you lose out on no rssi feedback through osd

[@bonafidepirate]

You need to set up your receiver so it switches channel 5 to RTH position on failsafe. It depends on what radio/receiver you're using as far as how to set that up. For the R9 module and R9MM that I'm using, I set it in the transmitter to "Custom" and set the outputs so the sticks are centered and mode switch goes to RTH. Some receivers you'll set everything how you want it to react at F/S then save those positions with a button on the receiver. The Dragonlink can be set in flight at any time, just set things up how you want them and press/hold the button on the transmitter module. Those are just some examples though. ;) I get RSSI via telemetry on my transmitter. Even without it though, you'll likely start to "feel" it in the controls when they get jittery and sluggish before a total lockout and failsafe. When it does drop completely (assuming you have your f/s set up right) it will turn back towards home, you'll regain control when it's closer and the signal is good again.

[@bonafidepirate]

No, it just worked. That old receiver has the original firmware it was shipped with some years ago, I've never updated it. The 4 in 1 module in my T16 was updated when I got the radio a few weeks ago. I think there might be a newer one out now but I haven't bothered checking. I ordered the internal module and will install it when it arrives, and the external one will be re-purposed for my Taranis later... lol

[@bonafidepirate]

FYI, You might need to do some tuning before it will bind. Even once it is bound you should do the fine tuning as well, it's explained here - github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/docs/Frequency_Tuning.md I haven't tuned anything since I've only used the 4 in 1 module on the workbench, I've been using the R9 to fly.

Having RTH on a switch is great, but I think the most overlooked feature of RTH is at a signal loss, of either flying beyond the range of the Rx, or some other issue. How do you set up the RTH to automatically kick in upon loss of control signal?

[@bonafidepirate]

Set up your radio so it moves each channel to a preset position in a failsafe, and make sure the mode switch is set to trigger RTH in a failsafe. I usually center the other controls and make sure the throttle is at cruise position or a touch higher.

Quick question, I was running the f405 board on the binary and I would get Wing oscillation when I would put it in stabilize mode, and do I have to run each ESC to a separate output or can I use the y lead to go to 1 ESC output

[@bonafidepirate]

If it's oscillating, the gains are likely too high. An autotune should have it flying pretty good. You'll want it flying well in manual mode first of course. The ESCs, if you mean the power leads, you can use a Y harness if it's easier, the positive and negative pads are tied together on the board anyway. For the signal leads, you can run them on a Y lead if you want and set it up as one single throttle output, or run them separate as two motors in iNav if you wanted to do any kind of mixing, like throttle differential to help with yaw or something. I ran them together on a Y lead with the Vector since it only has one throttle output anyway. Pull the red wire conenctor out of both ESC leads though so you're not using the internal BECs. The matek board has a better on onboard already for powering the servos.

[@bonafidepirate]

If you're using a Y cable plugged into one channel to run both servos, there's nothing you can do in the radio setup that won't affect both servos. Reverse one, they both reverse, etc. To fix it, you either need to do it mechanically with the linkages, or use a servo reverser between the Y cable and one of the servos. Another option, though not as easy, would be to open the servo up and reverse it by swapping the two outer wires on the feedback pot. The first two options are easier though. lol
