Well I finally got around to playing with my iNav equipped Enhanced Edition of the ZOHD Dart XL, and good news is it is flying and is as stable as the previous model. The new GPS bed and carbon rods in the nose section are nice additions, and I am glad ZOHD are at the very least listening to feedback from their clients, which a lot of other companies do not do! An awesome FPV cruiser for sure, and that F722 Wing is working quite well so far, so fingers crossed it stays that way!

Yes... you are right about the rear hatch improvement on the v1. I baught a later model that had the rear hatch with magnets, not screws.
However, my version doesn't have the motor reinforcement
OK, cool... so there is one more thing they improved... though I still don't see why these just couldn't be implemented quietly, without all this "Enhanced" edition... when it should have been like this from the start!
@@ArxangelRC i agree. The other thing that i kept hearing is that the v1 model ( havnt flown it yet due to lockdown) wants to pitch up when the throttle is increased.
Apparently the new model doesn't have this problem
@@beefybeef1326 Right... can't say I remember that, but its been quite a while since I've flown the V1! Can't say I see a pitch up when throttling up this one though, so I guess they have fixed it...
I’ve been flying my dart 250g a lot now so now I’m looking into getting this one 🎉
Cool! I believe you will not be disappointed, unless you expect it to fly and handle the same way... which it won't! So keep that in mind! This is a cruiser, not a proximity racer!
You might wanna have a look at the ar wing pro. It’s an amazing plane. Very well thought with amazing packaging. Just finished building it. You ll be amazed by the whole experience of it.
I have one of the new special edition coming! ;)
@@ArxangelRC There is a newer version of the AR wing Pro coming out?
@@MrMmDonuts Well you probably have seen it by now... it is white... not sure if its a newer version! But I do prefer white foam anyway!
@@ArxangelRC hell no... Darker is better. More official
@@k1ortia To each his own I guess! :P
Hey @ArxangelRC if you had to choose one small-to-midsize wing like this today, e.g. the Dart XL, the TalonGT Rebel, AtomRC Dolphin or similar, which would you get? I want to pick one up for travel and I want it to be able to carry a GoPro 10.
I'd go with the Talon GT! :)
Hey mate. Glad to see you checking out inav again :D But I suggest to catch up on the manuals before you do any tuning with 2.6 ;)
And regarding horizon drift. That was mitigated already a few years back but has to be set manually. in CLI put:
set imu_acc_ignore_rate = 9
set imu_acc_ignore_slope = 5
this is in there since 2.3 or 2.4 now and will reduce the drifting by a good amount. In INAV 3.0 there are also some changes in the code itself to optimize it even more.
But I really suggest to try out 3.0 and do an autotune in acro mode. You will be surprised how stable it will fly even in navigation modes. And turn on continous servo trim in the Features list.
Isnt it mad that it needs setting manually, youd expect it to be enabled by default rather than broken by default...
@@FunBitesTV why is that "mad"?
Fromthe beginning it was just a mitigation for the issue. Not a perfect fix. And it was not enabled by default initially because of possible side effects that where discovered over time. Like very windy and turbulent situations could cause the an infinite drift if the ignore rate is set too low but bad mitigation if set too high.
It was just now that a developer found a way to make it more reliable to make it safe to use on a daily basis. Keep in mind that these developers work for free and for the community. Unlike other systems that have either proprietary FC software or are paid for their development like Ardupilot with their partner program and involvement in hardware sales. They do it as a full time job.
@@MarcFPV actually this is just a patch rather than fix if you read about what those two things do, also each plane needs different values and from my experience, it still does not work. Inav suffers from horizon drift because of bad implementation for gyro
@@matejbludsky8410 yes of course. It is just a Mitigation, as I said earlier. And the Horizon drift has nothing to do with bad gyro implementation. It has to do with Physics. And you can't defeat physics.
Also Arduplane can suffer from it. But usually Arduplane is used on much more advanced hardware than our 30-60$ cheap budget flight controllers we usually use. They have dual IMU with higher quality and very complex code to estimate the expected G-Forces in turns and mitigate the issue so good that it is barely notable. And the Funny thing is, if you use Ardupilot on a F405 board with Single IMU you also can see slight horizon drifts after turns. As you see them today with INAV 3.0 still but at least they are under control now.
@@MarcFPV I just tried inav 3.0 and the drift is there and it's the same as before to be honest, this is definitely about implementation of the gyro they even said that on their explanation videos and they said they don't know how to fix it while back .. arduplane on f405 works perfectly well and I haven't seen any thing even close to inav horizon drift .. I use inav on almost all my planes love it but that drift is a serious problem and before they fix it, inav can't be used on anything serious (long range) I wouldn't trust it, it's gonna kill your plane
I always hated the rssi value that isn't really useful on r9 system... but after flashing ExpressLRS into my r9 hardware, watching signal level with dBm is MUCH useful. Really recommend the elrs firmware, amazing how capable the HW of r9 is when really good software is running on it
I guess so! But on the Clouds I've not had such issues, so really want to look into that before flashing anything! May get a system from a friend, so I don't mess with mine, we will see! :)
Nice flight and review, good you got to fly Inav but i guess you will stick to Arduplane most of time
Thanks! Yes, that I will! For me iNav is too experimental still!
If possible, please make a review on XUAV Talon Pro. Would love to here your thoughts......
Alright, got one coming! :)
wow amazing
Thanks! :)
There are people flying tens of kilometers out with Inav, why should it be crash immediately?
if you have had bad experiences with things before, your expectations will be much lower than those of other people.
Yeah, what nob0dy said!
I would've liked to hear more about the airframe flight characteristics than iNav...
Well I think I covered that... but in any case, this might also help: ua-cam.com/video/PKRKWohZGdI/v-deo.html
Let me know when it's running expressLRS :-)
Haha, you will know, will publish a video on it for sure!
@@ArxangelRC ua-cam.com/video/1vX5_XuZiMg/v-deo.html
Zohd also changed the air foil so the wing is different as well.
OK, nice... but why? What was wrong with it before? I don't remember having any issues with the plane's performance when it first came out!
@@ArxangelRC I think it was to stop it pitching up at speed.
Right... I will have to compare the old and new one again! :)
3.0 is out now. Lots of changes for fixed wing
Horizon drift?
@@FunBitesTV Have a look. And that's not even the final version that has some more optimizations for Turbulent flights. ua-cam.com/video/QiUn9tEBskE/v-deo.html
I can confirm horizon drift is still am issue and looked exactly the same to me on 3.0 as 2.x
@@matejbludsky8410 oh btw... don't take over a full diff from 2.6 to 3.0. And if you do for whatever reason, you must select a preset to apply the new default settings that optimize stuff.
@@MarcFPV yeah I'm aware, this was setup from scratch actually
I like the model, but the strange remarks about iNav are a big distraction. I know you usually like Ardu. Is it some kind of rivalry thing?
Not really... just bad experience with iNav in the past, and from what I see people posting about it... quite a few have issues of all kinds, sooo... lots of crashed planes!
I doubt iNav will ever really rival the performance of Ardupilot for fixed wings but the iNav 3 looks really good. It is way easier to set up than Ardupilot. I tend to agree that it was jarring to see 2 year old experiences being reported in the same week as a huge update to iNav was released.
You really should flash the latest iNav and on that plane and do a video so you can update your impressions.
@@marcdornan1454 Yup, I will!
Is it not possible to fly these without all the flight aids?
It is!
INav is pretty good, only had one FC crash with it but that was caused by the Omnibus V1 Clone, I guess. :/
Right... well we will see when I upgrade to iNav 3.0! :)
@@ArxangelRCMy Mini Talon with INav 3.0 is running pretty well so far, but on a MatekF405 Wing ^^
@@fpvleo2606 Right! Well... we will see when I get to it then! :)
Passando pra prestigiar aquele like e 🤜🤛✌
Thanks! :)
Nice to see things when smooth on initial flights, other the horizon drift issue.
(SD card issues a side ... know how frustrating that can be.)
I believe the the airfoil was modified on the enhanced version as well. Think more reflex, but you in a better position to compare, if still have original Dart XL at hand.
Hearing good things regarding INAV 2.6x and 3.0. Mission Planner for 3 has integrated options that previously required 3rd party tools to make full use of waypoint options. I assume you are in no rush to upgrade, instead focusing on turning you the Dart XL. Perhaps saving upgrade experience as a topic for a future video? Perhaps once have gained some confidence and explored the INAV 2.6x version and put Dart XL thru a bit more testing.
Will be interesting to see where your explorations with this 'enhanced' plane lead over the summer. Tweaks, mods, and flight plans.
Yes, somebody else mentioned that about the airfoil! I think when I was comparing the two I did look at that... but couldn't see anything noteworthy, might have to take a look at it again! Yes, I will be dealing with this in the next few weeks, want to improve on the tail section and will give iNav 3.0 a try... will make a video on it! :)
nice
Thanks! :)
Hi, you really should not use angle mode as it gives rather poor flight performance. 3D Cruise (AltHold + Cruise) is a much better Alternative. It corrects roll not based on what the FC thinks is downwards but based on the current gps direction. This results in a perfectly stable flight without altitude or direction changes. I do all my long range flights (up to 40km) this way. Also here is a good video from pawel (a leading INAV developer) on how to tune inav properly. ua-cam.com/video/A45vc4OihgY/v-deo.html
INAV is now at the point where it is really reliable and offers great performance.
I would really love to see more content about it. Keep your wings up ;)
But it still suffers the horizon drift ;( since rth is build on angle.. it's not reliable if it's gonna crash your plane in angle mode after a tight turn lol
How do you set both Atl hold + Cruise modes in iNav? Flip both at the same time?
I‘ve never have had a crash caused by INAV and I have anything between a Mini AR-Wing and 1800mm Skyhunter. If you want AltHold and Cruise at the same time just set the modes both to the same switch and range.
Btw, tight turns don‘t cause drift but very gentle long turns in 3.0 the problem is pretty much gone.
@@moritzadler4362 my experience is totally different inav killed 2 of my planes unfortunately ;( and the drift is happening anytime you use elevator especially in turns tighter worse drift
iNav 3.0 is out and available...
I know... will see if I will update!
Angle Mode is not a self levelling mode, never has been... that's Horizon Mode.
The AHI has never worked properly, unless you intend flying in fog or cloud, it's a cosmetic nicety that simply clutters your view IMO...Good to see you trying it again though... iNAV 3.0 is available so they say..🤔🤔😳😳😯🇬🇧
Yes, it is available, and I will be installing it in a bit, but want to try a few other things first! Why would Angle Mode not be a self-levelling mode? It is, as far as I know... the difference is, there are angle limits on banking and pitch, whereas in Horizon you can do a roll, its just that the plane will self level after that!
@@ArxangelRC I think you answered your own question. Angle Mode simply limits bank angle to whatever angle you choose to set it to. It does not self level from a banked angle position. Horizon Mode will self level immediately you centre the stick. Big difference. I hope that clears it up for you...🤔🤔🇬🇧
@@EnglishTurbines Actually this is not the difference between the two modes! Angle mode has banking limits, but should level the plane as soon as you let go of the sticks! Horizon mode levels the plane as well, but has no banking or pitch angle limits, meaning you can do rolls and loops, but with self-level available when you let go of the stick! Angle mode is the same, just with banking and pitch angle limits, and sort of an EXPO feel to it, for a more relaxed flight!
@@ArxangelRC Nope..Angle Mode does not level the plane from a sustained bank angle.
Not now, not ever. Horizon Mode does.
🤔🤔🙄🇬🇧 Flown iNAV for years, trust me on this...
@@EnglishTurbines Right... will have to test it out... but it sounds insane to be so! ArduPlane has the Stabilized mode, which works like the Horizon on iNav, and then FBWA is like Angle... as far as I've read their descriptions!
Enhanced? They still used the pooper scooper nose...
Hahahahahahha... well I find that a charming feature, and quite convenient for cameras! :)
Hey it's me please start to Ship to India too please 🙏🙏
Ship what?
@@ArxangelRC rc planes
@@amritafagna130 I've never shipped any planes to anywhere other than Europe! Shipping costs are whats prohibitive!
@@ArxangelRC it's okay I think I have to move Europe 😄😄
@@amritafagna130 Haha, could be! :) If you move to China, you will be closer to the factories! :) Will be much cheaper to get these!
Kinda late on this one huh lol
HA... tell me about it... :(
