Talon GT Rebel - Round 2

[@MichelPASTOR]

Hello. Inav dev here. To solve the OSD elements going away instead of blinking: set display_force_sw_blink = ON

[@bonafidepirate]

Awesome! I'll do that and try it again before disabling the alarms. Thanks for the tip, and for the awesome firmware! lol

[@FarmerFpv]

You're one of the devs for inav, can you explain about Auto-Tune in which mode is it better to perform an auto tune? Acro, angle or horizon? If you're in an angle and Horizon does it defeat the purpose of getting a full tune on the PID controller because they work in two completely different ways? It's a very confusing subject and it would so many conflicting answers going around I would like to hear it from a DEV thanks :) and thanks for all you do I love inav it's amazing and very powerful. Keep up the great work.

[@MichelPASTOR]

@@FarmerFpv You should use acro because what is being tuned by autotune is the rate controller only. Using any other mode would interfere with the measurements.

[@FarmerFpv]

@@MichelPASTOR Thanks for confirming that for me. And I appreciate the quick response. Yeah I figured they were two different pid loops we are dealing with. Autotune tunes the rate PIDs I was confident that's how it worked. Angle mode you have to tune separately manually. Cheers Rob

[@bonafidepirate]

Noted! I will set up acro as a mode and try tuning again just to see what it comes up with.

[@richardmark4385]

Another great flight keep it up one day I'll get back up there you give me hope

[@bonafidepirate]

Thanks!

[@MrZeek101]

Never disappointed always a class act keep them coming thats one Bonafide GT

[@cormorano78]

When you turn right o left lost a lot altitude, I have the same problem, how can fix it?

[@tenten8401]

Hi, I recently just totally destroyed my AR wing in a crash, do you think this would be a better buy than the AR wing?

[@bonafidepirate]

They are definitely different planes. I think the Talon GT is less forgiving than the AR Wing, and the AR is more likely to survive a crash. I'd call the GT a more advanced model. The AR will probably give you more "bang for your buck". That said, I've got a new wing in the mail so I can replace the left wing that I broke on this one, and will be flying it some more in the future. I've got a couple of other projects too, so not sure when I'll work on them all, but I've got some stuff to keep me busy for the winter... lol

[@muttbone01]

What is the musik at around the 10min mark?

[@Ad-VentureBear]

Hello, as i have the same plane and struggle with the settings, could you share your pid/piff settings? thx a lot, greeting from Austria.

[@traxxi2003]

Hello! Thanks for posting this video! Can you offer details on the new prop?

[@properlytwisted2172]

Awesome!!!! Really cool watching the progress on this one,Thanks!

[@Devil6CR]

Hi, I just ordered this plane, I'm not going to take the chance with the motor as I hear lots have iss6with the magnets letting go. I'm going with sunnysky 2216 1400kv and a genfam 9 x 5 folding prop. It's only a bit more of than stock. Would that be okay for prop setup? For fpv I'm going TBS crossfire. Do you know if it has enough space in the nose for a sjcam sj8 pro. I'm going with kopilot for fc. How do it land on stall, do a reverse or brake need to be installed in short landing areas?

[@theroc495]

Can you tell me what you AUW is/was? And, do you think aerobaut 9x7 folding props with a cobra 2221/16 940kv would work on this build? I ordered a mini talon and have all my electronics and fpv gear bought for it, unfortunately, with the covid 19 thing going on, I can't seem to get one shipped...I've actually bought 4 mini talons and all have been refunded, so I have all this gear just sitting and waiting...but I could gave a talon gt or dart right now to make something work...by the way, I'm no fan of sunysky

[@briankoch7041]

I have the disappearing warnings also. Ominibus f4 with swift 2.

[@bonafidepirate]

You may have seen it already, but "Michel PASTOR" (an inav dev) explains the issue and offers a fix in reply to another comment below. "It is an issue with the OSD chip hardware blinking handling on some flight controllers. We haven't been able to track down the exact source of the issue but it doesn't seem to be software. Personally I never had this problem. Turning on display_force_sw_blink makes the blinking handled in software instead of hardware thus solving the issue." I've yet to try it, but I expect it will solve the issue. I will most likely end up swapping cameras again anyway. lol The issue wasn't there when I was using a different camera before this one. In CLI, "set display_force_sw_blink = ON"

[@beison8000]

Older video... but do you have a recommendation for the specific control horns you used to lower the throws?

[@bonafidepirate]

I used Dubro 1/2A control horns because I already had some, but really anything that's durable and the right length will be fine.

[@beison8000]

@@bonafidepirate Thanks! Hey also, it's been some time now--do you still fly this model? Any comments now vs a year ago? Thanks for your insight!

[@seanmetzger4780]

Also, when you got that bounce, you had slowed to about 25mph when doing pitch tuning, when you have been doing it at 35-40 before, try and keep your speed during tuning at as close to the same cruise speed as possible, the plane likely jacked up pitch gains due to the slow speed, and then oscillated. This is why they recommend turning auto tune off before landing, as the slow speed will reset undesirable gains

[@bonafidepirate]

That's GPS ground speed, and there was a fair bit of wind during the flight. Air speed should have been pretty consistent at the same throttle. I've read that it's the shock of landing that can confuse things, not so much the speed. There's so much info spread around though, a lot if which is conflicting. lol I'd LOVE to see a definitive guide put together, but it's always changing and evolving, that guide would be obsolete in a week. ;)

[@BlindedByEvil]

What size or weight of battery would you recommend using? I am struggling to take off with 4s 4000mah weighting at 450g

[@jetrg12]

Any idea of how to mount the little standoffs on the wood plate for mounting a square flight controller? They just fall down if pushed through the holes, I am planning to mount a micro vector without its case

[@bonafidepirate]

I'm not sure, I never used those. Looking at them, I thought they would just drop through the holes too... lol My best bet would be either glue the standoffs into the plate, or use the case and stick it down with mounting tape. That's how I mounted the fill size Vector in my Dart XL, and the F-405 Wing in the Talon GT. I'd probably try mounting the standoffs to the board, then put a blob of hot glue on each hole and press it into place, making sure the keep the board level and off the plate/glue so you could remove it later.

[@jetrg12]

Great thanks! I will try putting a blind nut under but not sure if I can as the space under is tight

[@alexkerr306]

Good we all back to learning n having fun Cheers. Enjoyed video..

[@horsship]

Why does your flight timer disappear at the end of the flight? Great flight though!

[@bonafidepirate]

I'm guessing the same issue with the altitude and distance disappearing once they reach the alarm values. I have an alarm set for the timer too, but don't remember what the value is. I just set all those up with some pretty conservative numbers at the start and haven't taken the time to adjust them yet. Michel Pastor commented and suggested there's a fix for it, so apparently a known issue... lol It only showed up after switching to camera for the HS1177. "Hello. Inav dev here. To solve the OSD elements going away instead of blinking: set display_force_sw_blink = ON"

[@MichelPASTOR]

It is an issue with the OSD chip hardware blinking handling on some flight controllers. We haven't been able to track down the exact source of the issue but it doesn't seem to be software. Personally I never had this problem. Turning on display_force_sw_blink makes the blinking handled in software instead of hardware thus solving the issue.

[@horsship]

Michel PASTOR Thank you for replying.

[@heyjackfpv5469]

Inav or Vector ? whats you favorite and why?

[@bonafidepirate]

Easy answer, it depends... lol They're both great, but different. Vector is refined, reliable, easy to set up, has support available from the manufacturer when you need it, but costs more. iNav is cheap to set up, versatile given that it runs on various hardware, but setup is more demanding and time consuming, it's easier to make a mistake, and support/help usually comes from others in the community. Being open source, there's virtually no limit on what inav can do depending on how deep you're willing to dive in... lol

[@heyjackfpv5469]

@@bonafidepirate thank you for the advice 👍👍👍

[@jocelyncloutier]

Many many thanks for your great video. I am relatively new to iNav and I have been struggling with what I now believe is a high pitch gain. I will certainly try your approach. Also, I do not recall reading that auto-tune should be done in angle mode rather than manual mode. Do you think it matters?

[@jocelyncloutier]

I got an answer to my question from Michel Pastor (another comment to this video): "You should use acro because what is being tuned by autotune is the rate controller only. Using any other mode would interfere with the measurements."

[@NMdesertracer]

Nice flight!

[@bonafidepirate]

Thanks!

[@DuckyRC]

I'm having some pretty severe wobbling with this model on inav, do you think you could post your inav dump somewhere?

[@cenabitednbfpv587]

My motors slipped mags also on 2nd flight, so got new blue v3s and I have a v2 here also, I'm running a tbs #capriah prop trappy says it's good tons of power feels huge, but flys great. Any recommendations? Thanks for all your help as always fam

[@fpvquadjockey9195]

Which do you favor more, the Talon GT Rebel, or the Dart XL? & What’s the biggest reason?

[@bonafidepirate]

Right now, the Dart XL. I find it's a little more forgiving than the Talon GT in it's flight characteristics. Keep in mind though, that so far I've ran into a number if issues with the Talon GT that are not necessarily due to the design, but things like the loose magnets in the motor that I think at least contributed to the tough launches early on. (lack of power when it's needed most... lol) I'm running iNav in the Talon GT and it's still somewhat new to me, relative to the Vector than I'm using in the Dart XL. A lot of the time I've spent so far with the Talon GT has been fumbling around with inav getting it set up better. I know the plane has more to offer, it's just taking me longer than expected to get there... lol Couple that with unfortunate timing that set me back a couple weeks from the hobby and I'm sure all that influences my opinion of the plane so far. I'm sure it will change once I've got more time on it. They are both nice planes though, for sure. Personally, I do prefer the looks of the Dart XL, but that's all it is there, cosmetics... lol

[@fpvquadjockey9195]

Thanks, I can appreciate all of that. If I buy either one, I will probably plan on replacing the motor out of the box with the SunnySky that you used. I am partial to the looks of the Dart as well, but if there was a major reason you liked the Talon better I’d take that into consideration. My main concern is the nose of the Dart breaking off, it is becoming very well known for this online. Just not sure how little force it takes to break.

@@fpvquadjockey9195 thw talon gt rebel seems to have the same nose design and ive seend it break on another video, so i think its just the nose design and foam they are using nit sure if one is more durable then the other, definitely on the fence between buying a dart xl or a rebel gt not sure which one yet, the dart xl seems to fly way smoother thi

[@benjaminwinston4185]

What control radio do you use? Frsky 2.4ghz?

[@bonafidepirate]

433MHz Dragonlink UHF

[@FarmerFpv]

In Auto-Tune I'm pretty sure you're supposed to be in rate mode as Angle mode uses a different PID loop, it's what I understood from the wiki. Just like on betaflight the regular PID loop does nothing for Angle mode. When I tuned mine in rate mode it actually did a really great job. I might have read it wrong but I swear it's what it said? I guess It might work on all modes but won't hurt to double-check. But I could have sworn it said to use rate mode for Autotune so you can push it to its limits, Let me know what it says if you re-read it. Either way already looks really smooth to me. What was the wind speed? Round two successful ding ding lol

[@bonafidepirate]

I've read conflicting info on that all over the web... lol In one of Pawel's videos, in the comments he says in a few places you can use stabilized modes, but he mostly flys acro so he autotunes in acro. (comments for this video kzbin.info/www/bejne/i4Cql3ZppduVja8) The Wiki here states that autotune runs on top of angle/horizon/acro modes which suggests it should work in at least those. (github.com/iNavFlight/inav/blob/development/docs/Autotune%20-%20fixedwing.md) I know it definitely changes PIDs (PIFFs? lol) when running in stabilized modes. I couldn't say what's best though, as I said this is only the second build I've done with inav and there's a LOT more that I don't know, than what I do know about it... lol I'm learning though! If I figure it out I may revisit this later, but for now it's flying pretty dang good... lol

[@seanmetzger4780]

Auto tune can be in acro/angle/horizon...trim should be done in manual

[@FarmerFpv]

@@bonafidepirate exactly if it's not broken don't fix it lol

[@seanmetzger4780]

Change the stabilized yaw in the mixer to rc yaw, so that it doesn’t crab. I think inav’s rudder implementation for stabilization is a bit primitive. Switching it to rc only makes it fly much better

[@bonafidepirate]

I've not heard of this rc before, I'll read more about it!

[@bonafidepirate]

OK, just read... lol so RC is just basic passthrough yaw control, with no stabilization on yaw axis. Got it! I guess it might take out the little bit of wag I saw here and there. You'd still need to crab into the wind to maintain a heading with a crosswind though, physics and all... lol

[@seanmetzger4780]

bonafidepirate a friend of mine had an issue where his plane would fly almost sideways in a 1-2mph crosswind. We tried to tune it out over 3-4 flights and then just switched the mixer to rc yaw, and it flew perfectly. He did have to change the -100,100 in the mixer because rc yaw was backwards from what stab yaw was.

[@waldemarkraus2855]

@@seanmetzger4780 I´ve done the same on my nano talon, works great for months now

[@traxxi2003]

Sorry but how do I change the mixer to RC yaw? Having similar issue with ZOHD talon GT.

[@jetrg12]

Pan and tilt? :-)

[@bonafidepirate]

I'm thinking the same thing! lol

[@jetrg12]

I am still wondering if it is possible to have a standard servo rotate 360degrees and not continuously, the GWS is very good but too heavy

[@Starbuckin]

Not bad bro. I'll still take the Dart XLE over the Talon though... Oh and Vector over Inav...

[@bonafidepirate]

I still feel more "at home" with the Vector, no doubt... lol I know my way around it though. The more I learn about inav the more I like it, but it's definitely a more "involved" set up. I'm enjoying the challenge and learning something new though. I like the price of the hardware too. The Matek boards are really nice!

[@radzgardiner8108]

Thats a great video. You should join the facebook INAV Fixed Wing group if you haven't already. There lots of great info to gain and to share there, i'm sure lots of people can learn from you there and you might learn something there too. Keep 'em coming ;)

[@bonafidepirate]

That works! lol

[@jedslather]

Too many people report issues with the stock motors! For the price of the plane it’s just unacceptable.

[@bonafidepirate]

Apparently they switched to Sunnysky motors now. (according to ZOHD) Worst case, a $20 Sunnysky motor solves everything. That's what I'm running on this one now... lol

[@jedslather]

bonafidepirate @and that’s great, however it’s good to know you need to have or buy a new motor the moment you buy this model 😁

[@bonafidepirate]

@@jedslather To be fair, only a very small number of people had the motor issues relative to the number of models that went out (as far as I know). None the less, I posted a video explaining the problems and suggesting people check theirs as well, as did others. Zohd posted a notice on Facebook about it as well. Shit happens, some bad motors made it out into the wild and it was addressed. I wouldn't blacklist a model for that alone. ;)

[@jedslather]

bonafidepirate @ you are the3rd KZbinr who had the problem, I’m not saying to blacklist it, just get a spare motor if you buy the plane if you don’t have one or you will maybe need to wait x days months depending where you’re located in the world. That’s why I prefers kits 😉

[@bonafidepirate]

@@jedslather Yeah, I agree there. A kit option would be nice. I would have fit it with gear very similar to what comes in the PNP anyway, but it would have saved some trouble with the motor thing... lol More options are never a bad thing.
