Arduplane auto-takeoff and auto-land test

[@uavpilot6715]

You should consider installing an airspeed sensor, it will make the landings a lot more efficient, as the flight controller doesn't have to guess what the wind speed and direction is.. I like your videos, keep them coming...

[@n1vca]

many thanks for sharing The RTF wing Parrot Disco does the same but to make every landing a smooth one, when in auto-landing mode during the very steep descend they activate an ultrasonic ground sensor that once ground is detected (last few meters) they instantly lower the descend angle, turn off the prop, it folds back and on the last meter of height they fly almost level and bleed off the airspeed and land very gently. It is a great help for a beginner but I'd always prefer to land manually if I only could - its not an option here. For any Parrot Disco user - please assure you have another 10m of space behind the planned landing spot, because it overshoots by design. If you factor that in, you can auto-land it within 5 meters "on the spot".

[@Rapsaj]

Awesome video! Really liked it! Quick note: Unless you set your home location manually, it will be set automatically to where plane is powered on initially.

[@iforce2d]

The docs say it will be set to where it's armed: ardupilot.org/plane/docs/rtl-mode.html

[@IlliniRob1]

Thanks for making this video! I'm learning how to use Mission Planner and this was helpful. However, everyone should keep in mind that without differential gps receivers and modules, the accuracy isn't extremely precise. Expect errors on the order of 5m laterally and 10m in altitude -- and that's before taking into account precision of the autopilot itself. Pulling off landings in such tight quarters as these (with the expected gps errors) is impressive.

[@6toeNL]

Really helpful. I like it that you explain every aspect of ardupilot. Good job!

[@mrstocks]

informative video, well pieced together and organised, well done.

[@theodoreomar9036]

you all prolly dont give a damn but does anyone know a method to get back into an Instagram account? I somehow lost the account password. I appreciate any tips you can give me.

[@wyattfelipe1458]

@Theodore Omar Instablaster :)

[@theodoreomar9036]

@Wyatt Felipe thanks for your reply. I found the site thru google and Im trying it out atm. Looks like it's gonna take quite some time so I will reply here later with my results.

[@theodoreomar9036]

@Wyatt Felipe it worked and I now got access to my account again. Im so happy! Thanks so much, you saved my account :D

[@wyattfelipe1458]

@Theodore Omar No problem :D

[@rckeith]

Great information been messing with ArduPlane for some time with a Hobbyking EPP-FPV and I've had some good results but not been brave enough to try auto launch or landing. I'm still using the old 8bit APM 2.7 which still does a good job. Thanks for sharing

[@godfreypoon5148]

Efficiency? She's fiiiiine mate. I'm pulling 60 amps from a 10S!

[@seanyfpv]

nice video! i know it's old but just for other's reference there is a "auto mission reset" command that you can bind to a rc input, and i'm assuming it can reset the auto mission waypoints while still flying, because otherwise it only does it when you disarm

[@stephengloor8451]

With all my smaller wings that are hand launched it set MIN_ACC pretty low and no delay. Then I put the plane in auto and give it a shake to start the motor and launch with a side release without really throwing. The bigger Opterra is bungee launched with the motor off. I have the default delay and min_acc set. Hook on the bungee and put it into auto and release. Goes off without a problem. Wings are hard to throw especially the smaller ones that have nothing to hold on to.

[@lasersbee]

21:16... I would use the Auto Takeoff but not the Auto Land... The Auto Hand Launch Takeoff seems to work quite well. Thanks again for the Video..

[@termitehards]

Masha Allah ... only managed one successful autoland a long time ago and never done auto takeoff, insha Allah this will be very helpful ... thank you, can you share your mission please.

[@ConsultingjoeOnline]

Cool. I've always wanted to do this. Looks fairly straight forward. Thanks

[@bigtfpv]

Thank youf or this recent series. I am trying an apm 3.1 in a Nano Goblin. Your videos have been very helpful. Keep it up!

[@vishalbharati9384]

awesome video sir, helped a lot, i wanted to ask will auto pilot manage throttle on it self or we need to increase / decrease it manually, is there any setting in mission planner so that throttle is controlled automatically, once again thank you sir

[@TomPittenger]

I REEEEAAAALLY need to make a video explaining auto-landing mission planning. I've seen this method in this video a lot, it's tempting for people to plan a mission with spoon-fed waypoints down to the ground and then a LAND right at the end. The correct method is two way points, one in the sky, one on the ground. Don't spoon feed.

[@ir0nm8n]

Looking forward to it

[@ZuNunchaku]

what is spoon feed?

[@d_praz5946]

Sir, do you have any tips for the Settings on the mission planner to mannuver planes sharper and more agile?

[@Bill-NM]

If I raise the throttle to 1/2-way (after switching to AUTO), the motor starts, which it's not supposed to do (all other settings/parameters are correct)...also, I've seen other videos where the pilot leaves the throttle at ZERO, and then throws. So which is it? Thanks...

[@iforce2d]

"When the auto takeoff mission command starts (usually by switching to AUTO mode) the autopilot starts in “throttle suppressed” mode. The throttle will not start until the conditions set by the TKOFF_THR_ parameters met." ardupilot.org/plane/docs/automatic-takeoff.html

[@nmrlab3807]

@iforce2d Thanks for the honest review. What would you recommend for a flying wing for novices?

[@iforce2d]

tbh the one in this video is probably the best (C1 chaser). But if you have access to foamboard you can make a simple wing pretty easily, and less stress when bashing it around as a noobie.

[@nmrlab3807]

@@iforce2d Thanks, I'll see if I can find C1 Chaser at a reasonable price. But, I don't mind making one with foamboard; Any particular plan that you can share with me?

[@SteveLoves2Fly]

What I think would be really helpful is for you to nail a full automated flight. Then place coffee can lids at the nose of each location the plane landed. Measure how for off it was from your desired location. This is a very cool video]. As an also mention, my Flysky throttle lever is also missing the nub. It's a conspiracy!

[@ChristianMixLocutor]

The question that no one asked is the most important one: I have flying wings, and I want to use the auto takeoff, I create in the mission planner only one waypoint that would be the takeoff, but I create this point each time I change my flight location or can I just turn on the auto mode, and will he know that the place should also takeoff, even though I'm hundreds of miles away from the point I created the first time?

[@iforce2d]

The auto-takeoff command has no lat/lon position. It only has an angle of climb and an altitude target.

[@ChristianMixLocutor]

Okay, I get it, so I can create the first point anywhere in the world aprnas to create the auto takeoff function, but when it's time to use it no matter where I am, very good then, because it's the lack I feel when I use my apm with my mini talon. Thanks a lot for the help. Success to you

[@kenniffss]

That's good to know... I have a 6 position switch on my Taranis with overrides to manual or rth, i could just use one of my modes to enable it i think? How long does it continue the climb out from auto launch? Until you give it input on the sticks or switch out of the mode? Thanks.

[@TheWebstaff]

Its back!.. why did the video disappear, If you don't mind me asking?

[@lean.joseph]

Hey, are you still active? There are certain stuff I have to ask you, regarding this project. Its very important Would you mind if we talked over mail?

[@3drccustombeasts381]

Hello. could you kindly tell me if there is a way to adjust dead band like there is in betaflight. I've been discouraged from using my APM because of drifting and I know it could be corrected but no matter how much research I do I can't find a way to set dead band in mission planner

[@iforce2d]

Sounds like maybe your transmitter just needs to be trimmed so that the pitch/roll (or whichever is drifting) is centered. You might also be able to reduce the effect of small movements near center by increasing the expo in your radio.

[@Chris-vc1dh]

hello, can you tell the difference in flying between inav and ardu?

[@iforce2d]

I have not tried inav for many years, so I couldn't give an up-to-date assessment. Originally when I tried inav in 2017 it was great for multirotor but plane behavior seemed inferior to Ardupilot (I could not trust it to do RTL or simple loiter). I hear inav has improved a lot since then though.

[@mehmetizzetkose2488]

Hello, I am watching your videos with interest, they are all very successful, congratulations, could you please send the full parameter list for the z84? I want to compare for my z84, thank you in advance...

[@iforce2d]

This is not a z84, it's a C1 chaser, a bit larger. For my z84 I used the same parameters as this guy, he listed the detail on his page: www.supermotoxl.com/projects-articles/fpv-uav-models-builds-reviews/uav-wing-wing-z-84-845mm.html

[@sparkles9868]

Looks very interesting What flight controller did you use ?

[@iforce2d]

kzbin.info/www/bejne/qqi6anaXh9GdY7c

[@mariobradic8898]

Are there some possibility for autopilot to determin the wind? If there is IAS sensor on the plane, can the AP make an information of wind, with data of IAS, current heading and ground speed from GPS. I am asking regarding the autonomous landing into the wind.

[@iforce2d]

Apparently it can determine the wind direction and strength from the throttle and groundspeed reaction, even without airspeed sensor. It has been working so well that I don't know if I will bother putting the airspeed sensor on. The landing direction is set by the user, it cannot be calculated autonomously because of obstacles etc.

[@wingsmh27]

How to set a speed and What speed you set in default.?

[@fiftysixhaikal7067]

Did i'm correct, i saw the way you armed the plane with tilting the plane nose down. Is this correct? If it's correct may i know what parameter should i changed

[@iforce2d]

I think the plane should be facing in the direction you want it to climb out, when you arm it. The pitch/roll should not matter. In any case all these details are in the Ardupilot web page...

[@Tommyboytomsters]

Thanks. Deciding inav or adru

[@iforce2d]

Now that ardupilot runs on the cheap boards, I would go with that, for planes.

[@Tommyboytomsters]

iforce2d seems both software inav and the ardu run on most boards , really Amazing how far processors have come

[@aminezitouni8427]

Recently I followed all the videos in your youtube channel "How to Build a Cheap Quad" and i learned a lot of things that led me in my project, thank you. Actually, I'm working on my quadcopter project and I want to ask you if you can guide me on how to add a "return home" function to my quad using the GPS module.

[@iforce2d]

I'm planning to make some videos about GPS quad soon.

[@wingsmh27]

As speed is set in m/s for air and also ground please tell both speed you set in mission planned

[@iforce2d]

There is a min and max speed setting somewhere, but I didn't change it, so whatever the default is, was my setting.

[@reyniersnyman9536]

Thank you, very informative, great work man!

[@pyrowales]

i would try a matek f411 board and inav

[@iforce2d]

Actually I haven't touched iNav since I tried Arduplane.

[@brkfpv60]

if loses transmitter connection on auto mode , what will happen ? continue waypoint or return to launch ?

[@iforce2d]

Depends what settings you made. See "Long failsafe action" description here: ardupilot.org/plane/docs/apms-failsafe-function.html

[@mkleespies78]

so notice this is 4yo... I'm new to this do I need to do all the mission planning for tkoff if I'm using a switch?

[@iforce2d]

I'm pretty sure the takeoff command is only ever part of a mission, so yes, you'd have to start in auto mode and have at least those commands in the 'mission'. But you don't need to create any waypoints to fly around in an actual flight path - after takeoff just switch into manual or whatever other mode you actually wanted. I ended up not using this though. If you're hand-throwing it might be easier to just use FBWA for auto-level, and use a mix on your radio to have the plane climb slightly. I described how I do that in this video. kzbin.info/www/bejne/sJy2qamQm7-fgrc Where I live now, I can throw the plane from the top of a long slope so I don't even need that these days - just plain auto-level and the ground drops away naturally.

[@alirezaghaderi]

Best video sir... Thanks for sharing

[@hoanguyenphuong6405]

GPS needs compass right bro ?

[@iforce2d]

For a plane, not really. A plane cannot hover in place, and can only move forwards (not sideways or backward like a multirotor), so the direction it's facing can be inferred from the change of the GPS location. It's not exact but it's plenty good enough. I don't use a compass on any of my planes.

[@GeertDroid]

What brand and model is this plane?

[@iforce2d]

It goes by the name "C1 chaser", doesn't seem to have a brand bit.ly/2XKIWji

[@aussiemozzie7216]

Great video mate love your work keep it up. Have a pixhawk quad i'm building and these videos are helping. Thanks

[@bewithyou2]

is this zeta wing wing? edit: oh me blind.-.. its the chaser :P -- which wing you like best under 1m wingspan?

[@iforce2d]

The only wings under 1m I've had are the bonsai, s800 and z84. Would probably have to go with the z84 I think :)

[@derivas007]

i don t understand when you use auto take off you need to let you throttle to zero position or middle?sorry but my english is not good

[@iforce2d]

Throttle must be non-zero.

[@SAMETELMACI]

ı wanna land but not disarm after again takeoff how can ı do

[@iforce2d]

That's the default behavior. You can change the settings to use the throttle/rudder stick to disarm, but I don't think I did that in this video, so I don't know why it disarmed.

[@QuickCookie]

They should make The Back to the Future 3!

[@iforce2d]

There is a 3... you mean they should make 4 ?

[@sUASNews]

The 3 was bogus numbering by a manufacturer, there is a 4 coming but again it's not from the project. To combat this I think names will be used moving forward. The latest is the Cube. As to back to the future well.

[@QuickCookie]

iforce2d Yes, The 4

[@markgreco1962]

Does this feature work with a quad copter

[@iforce2d]

auto-takeoff and auto-land? Sure, but you don't throw it to launch obviously :)

[@markgreco1962]

iforce2d I think I’m in on this project I’m going to build the plane and order the stuff from bang good

[@sUASNews]

You can throw to launch kzbin.info/www/bejne/i6iclJeqoJ6ChKs

[@iforce2d]

ah, I actually saw that video, didn't realize it was arducopter. Mark, I ordered a FX79 to make a better setup and try some mapping, maybe by the time it gets here I'll be able to make a less fumbling video about setting it up. Not sure if I'd go for this particular flight controller again because the lack of connections is quite restrictive....

[@markgreco1962]

iforce2d I will get the plane complete and flying and wait for that video. at least I have something to do for a while THANKS

[@atw98]

PLEASE my Digger friend keep up these really easy to follow step by step instructions. My main complaints with pixhawk are the fact that there should be a hobbiest GUI and an Advanced GUI. It took me only hours to get Inav Air3 setup as the Gui is just so simple and you can go as deep as you want. Pixhawk you practically need to learn it all. I have had a pixhawk or pix clone not sure, for over a year never flown. Can get all switches going and sticks but Id never put it in a plane because I dont know if the rest is set. Your videos are fantastic am spreading the word. I am taking for granted that these settings will work on any pixhawk board? I hope so or Im going to look sillier then my normal self. Also any email to get you on? Id love ro chat about trying ANDRUAV From across the ditch. Been looking for someone with space to try what looks like a great app. Love your thought, look it up if you dont know it. Its a 3g/4g flight program via android through mavlink. And there are no flight videos hence why Id like to work with another digger on the project. All the best Gus

[@SpeccyMan]

A hobbyist really ought to know how to spell hobbyist ;-)

[@atw98]

Nick B well what happens when stuck in a hospital bed with blurry vision trying to hit the right auto spell. But I totally think your write.........."-) (took me all night to think of that a little slow at the Mo)

[@atw98]

Nick B ok Nick B now you've stuck your head above the bunker can you answer the badly worded question. Will these settings work on the pixhawk? You dont happen to be a teacher or someone like my favourite uncle who is into correcting spelling and grammar? I actually think its a good thing as auto correct has made peoples use of the Queens English a wee bit difficult to listen to at times. Love ya mate.....;-)

[@ChristianMixLocutor]

My friend, people sometimes waste time talking about things that do not need to be commented on, there are people who waste time to speak ill of something wrong that you wrote but are unable to answer your question, but come the answer that you need. All the controllers that use the mission planner - arduplane, will be the same configurations, it is like inav, what changes are uart connections, and firmware, but the program configurations are the same for all boards, understood ? It's like windows, you may have different hardware, different drivers, but the windows configuration is the same, I have planes with inav and with mission planner, I use them with inav for simpler planes, where I make flights to 2 to 3km away, you can see in my videos, but when I want something really reliable use APM or Mini Pix, in the case of the mini pix radio link, it's an F4 card, but running a system much more robust than the inav, it's more complicated and laborious than inav, but much more tested and with less flaws, so for small wings, fast flights, jokes, I indicate that it continues using the inav, but if you want more robust things, use an apm or pix, many disagree, but no use, the arduplane mission planner is already more than tested and solidified when it comes to flight automation.

[@evo-labs]

Those landings look awfully fast. Is that normal?

[@iforce2d]

No, look at the link in the description for how it's done properly. But this was the best I could do with the trees there and the wind direction.

[@blondeguy08]

Thanks for making this video!

[@spikeydapikey1483]

That's some good shit right there!! ;o) Nice bit of kit as well. Be great for patrols if an alarm waz tripped, say, by zombies >.< hee hee!

[@spikeydapikey1483]

Edit: Would need a bungee lunch from the roof i'm guessing..

[@yxhankun]

good job!

[@mdafzalahmed4675]

Great job .. It's awesome

[@TheMadmacs]

it landed within 20 cowshits, thats a victory

[@grahamrdyer6322]

Great video but, I thought the whole idea of model flying was to take off, fly your plane and then land the thing manually.

[@iforce2d]

This feature can be handy for large planes which would normally require two people to launch them (too heavy to throw with one hand).

[@ViniciusCZanini]

It starts on 11:40

[@mdafzalahmed4675]

Awesome

[@sUASNews]

One million points

[@sUASNews]

It will climb to the height you specified before starting nav, I think that's why it didn't turn when you expected it. I also hand land BTW, but its a jolly cool feature. Well done you aced it and as with everything the second aircraft you set up will be much easier.

[@iforce2d]

But it did turn, when I didn't expect it to. I expected it would climb to 70m in a straight line before doing anything else.

[@sUASNews]

iforce2d My bad, yes that is what I would have expected. Maybe try on a calmer day and perfect the pattern for a windy day. Very small area you are using, so a great effort!

[@iforce2d]

I tried a few more times off camera and I don't think it was the wind. One time right after the motor started it did an almost 180 degree turn at full bank about 3m off the ground, I had to hit RTL to save it. So I'm kinda wondering if the mission was not reset and it was going directly to the LAND waypoint that time. I'll have to look into how I can properly reset the mission from my radio, this must be something a lot of other people have had to deal with already...

[@sUASNews]

I have had to spend a lot of time considering what is exactly going to happen when I add the land, watch all the missed and long approaches. kzbin.info/www/bejne/pmqYhYtqrJaBgqM that has been solved with a LiDAR. How much are you slowing down for the landing? That will give it more time in that short distance.

[@KurtisRupnow]

Good information. Also a lot of extrenuous talking... and quick jerky camera movements.

[@curvs4me]

Maybe its in feet
