My Longest RC Airplane Flight 

Thanks! 😄

That sounds awesome! (except the sunburn, haha)

Bro that's crazy I just got my radian yesterday and I'm gonna fly it on Sunday hoping for a long flight time but not that long XD I've got 4 1 cell batterys

Radians are fun.

Thank you so much! 😄

Yeah, haha I’ve thought about this too. I’d love to have several batteries and safely drop them as they are depleted, but it seems tricky, managing the voltage and battery connections

Dropping LiPos around might be very, very dangerous unfortunately.

You can drop off package as long as you have an autonomous flights controller such as pixhawk You ser up the waypoint ( specific location) and the pixhawk will send a signal to the servo to release the package

@@idiotequedwaal good thing it’s not a lipo😏

Many thanks! 😄

Many thanks! 😄

Wouldn’t it be cool to send it at a general heading towards another city 150 miles away where you have it land and drop off a usb and fly back . This would be supper cool . Probably 😢illegal

@@j.s3612i don’t think it would be illegal if you register the flight

Isn't 300 miles 482 KMs? That's more then this flight. Great flight but 2019 with an old Disco did over 300 miles. Good to see there's people striving to do long range though.

Thanks! Have you seen the drones that perch on power lines and draw power to recharge?

Many thanks! Sorry for the late reply. Yeah, a few days later I got on Google Maps and started drawing distance lines to see how far it could have gone on a one way mission.

Well said! Thanks!

Thanks so much! It’s a fantastic plane!

Thank you so much! I really appreciate your encouragement! I plan to film a couple new videos this weekend. One about my Talon 250g and the other about my nano goblin. Both of them squeak in under the 250g limit. The nano goblin actually has HD recording too. Both of them are very amazing for their size and weight. I’m talking hour+ flight times if you’re cruising and 30 minutes of ballistic ripping.

Thanks! The autopilot is nothin’ fancy, just a Matek F405-wing running arduplane 3.9.11

F405 wing is a fantastic product by maytec,I still use them with inav,great achievement there.

Many thanks! 😄

Thanks! Arduplane flies really smoothly.

@@MatthewHeiskell yeahhh.. really is. Greetings from indonesia 🇲🇨

Yeah, it was very relaxing to watch and check everything. 😄 thanks!

Thank you for taking us with you! ​@@MatthewHeiskell

Thanks! Will do! 🛩🛩🛩

Hey Spike! Thanks! I bet that you noticed the square APC prop 😁. I've gotten a lot of use out of that info that you taught me (among the many other things)! Thanks again! That's a good idea to explain my arduplane settings. I figured that Andrew Tridgell was a dev, but I didn't know he was the lead dev! Very cool! How are your projects going?

@@MatthewHeiskell You should join Aerorozvidka fren. You will enjoy it.

​@@MatthewHeiskell*arduplane works with American military questionable human right record ... droning people in the middle east comminuted a lot of war crimes stop supporting baby - killers*

Multirotor can do very special things, but fixed wing is the king of staying in the air haha. I have both and I love both.

Thanks! I tried iNav at first, then I flashed arduplane onto the FC. What a difference!

Did you tried to fly with inav?

@@sarantis2 Yes, iNav is more user friendly, but Arduplane is better in every other aspect, especially efficiency.

@@MatthewHeiskell I cannot agree more. After this video I order the same plane

Yes, and money (~$300 battery). Congrats!!! Comparing to gtrick90's 4h 100 mile flight on 4s-7000 with the z84, 7 times the Wh to travel 3.4 times the distance.

Many thanks! 😄

Thanks Pedro! 😄

Many thanks! 😄 Glad that you enjoy this stuff too!

@@MatthewHeiskell yes!

Wow, that’s awesome! I’ve heard of an RC place that flew across the Atlantic too! Amazing!

Thanks! It’s fun to make them, and pretty easy when I’m stoked to share the results of this cool project. Cheers! 😄

@@MatthewHeiskell now you need to buy a 03 airunit by dji digital camera or add a gopro on your plane and your videos are perfect !

Very cool idea!

Not sure how you would do it, but with live video data you could capture the video frames as step 1. Then analyse the video frame image using some open source algorithm or even write something to analyse the pixels in the image. Might require some AI image recognition component. Step 2 use multiple image frames from multiple drone GPS locations, to try to triangulate the image GPS location based on the image pixel count distance from the edge of the identified image. If you can calculate the centre of the image ( after finding its edges ), even better. This might also need to take into account the orientation, direction and altitude of the drone. If the image is moving it would be more complex, but start with a stationary image. Some trial and error trigonometry might be required. You could use a test object with known GPS co-ordinates for your test image. Say for example start with something large like a small shed etc... Depending on your skills, you could possibly simulate the entire process in a 3D software environment or even in Microsoft Flight Simulator, using the the API programming functionality.

Thank you so much 😀

Many thanks! 😄 that’s awesome! It’s a great skill set to teach to future generations!

Thanks haha 😆

Thank you! 😄

Many thanks! Yeah, battery power is nice because it still works at night, or when it’s cloudy, or when the days are short. It is also pretty simple and cheap.

Thanks!

Wow! The only way I can think to do that is to slope soar somewhere with really consistent winds!

Many thanks! 😄

Many thanks! 😄

Haha, many thanks! 😄

Many thanks! 😄

Haha, thank you so much! 😄

It was not especially efficient, half of the endurance came from the Li-Ion cells that I used to build the battery pack. They have twice the energy density of a standard LiPo RC battery.

@@MatthewHeiskell oooh I get it. Do you think optimising the airplanes shape could have a major impact on flight duration?

Thanks James! I didn’t write the arduplane code. It is free and open source. It can be flashed to many different flight controllers. Just do a google search for “arduplane”. There is tons of info about it. I’m not sure of my next big project, haha.

Thank you! I appreciate you taking the time to write your nice comment!

Thanks so much! 😄

Many thanks! 😄

Thanks! 😄

Thanks! 😄

Good ideas! I bet a fully internal battery would improve the efficiency. Yes, even a faring would help too. I didn't update the data table because this is a different battery (4S 50Ah vs 3S 45Ah).

Thanks Brendan! I really appreciate hearing that! Cheers! 😄

Thanks! I love your work too!

Thank! 😄

Thanks! Yeah, switching to Li-Ion basically doubles your flight time for the same battery weight.

Thank you! 😄

Many thanks! 😄

Thank you so much! 😄

Many thanks! 😄

Many thanks! 😄

Thanks! 😄

Thanks! It is just a cheap FPV camera glued onto a servo. And the servo is glued into the upper edge of the vertical stabilizer.

@@MatthewHeiskell Awesome, very simple thanks for the response. Happy flying

@@Joneszee1969 I show the pan servo in another phoenix video. Here is a link that will start you at the exact moment, but You might enjoy the whole walkaround section: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-M-j0khC0x80.html

Many thanks! Yeah, I think that’s about as good as I can do with a 2.4 meter wingspan. Pretty amazing that you can just buy one off the shelf, swap the motor and prop and add a big battery and you’re good to go.

@@MatthewHeiskell yes, I see, and thanks for sharing this.

Thanks! Yeah, they made a fantastic design!

Thank you! 😄

Thanks! 😄

I was really worried about that, haha 😂

Awesome! Here's a good video about pack building. The only difference for us RC people is that we don't need a BMS (battery management system). We just need the main positive and negative and the balance lead for balance charging the battery. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tKg-jIrr_JE.html

Thanks! 😁

Thanks! I was using the Matek F405 wing flight controller's built-in current sensor.

Thanks! 😄

Thank you! 😄

Haha yeah! Check out the Sanyo NCR18650GA cells. They are the best for this type of endurance flying. You can get an affordable spot welder that operates using a Lipo pack. IMO, the best way is to build your own packs, but the ZOHD LION packs use the same proper cells.

Thanks! To account for the decreasing pack voltage throughout the flight, starting at 16.8V and landing at 11.3V, I had to over-prop the motor. So I had to limit the take-off throttle to 70% to prevent the motor from pulling too many amps and burning out.

Wow! That’s awesome!

Many thanks! 😄

Good question! Sorry for the late reply. I didn't have a waypoint mission loaded into the flight controller, so turning the RC transmitter off, or losing RC signal would put it into return to home mode, which is what is was already doing. Super Safe. When you have a waypoint mission loaded, you can adjust the flight controller's response to a lost RC signal. You can make it return to home OR make it finish the mission.

Thank you! 😄

Good question! Each cell in parallel contributes to the discharge rate capability. Since there are 10 cells in parallel, and each cell can deliver 10A, the whole pack can deliver 100A.
