Cell towers?

Ha, just call me Orville

The Australian drones are cardboard covered in wax, not foam board...

Laugh of amazement probably. Gotta have fun somehow

This is why everyone wants Taiwan.

On AliExpress at least I've noticed a HUGE uptick in Ukrainian flags (indicating the location of the reviewer) for electronic components. This would make sense.

Oh really! You are a genius

Haha. One day I'll make one worthy of FPV

That would be a fun project

and hopefully the two will never meet

Glad you enjoyed it

Thanks Jim. Happy sailing!

Ha, I guess it's possible

That would be fun.

@@AndrewNewton Flite Fest is at the end of June this year. Still plenty of time to plan an international trip. Just sayin'. . . But seriously, if you ever do consider a trip over here and genuinely hope to spend a bit of time with the FT guys, Flite Fest (and the month leading up to it) is not ideal. With all the work that goes into the event and so many people here, it's hard for the guys to find much time to mingle outside of photo ops, autographs, or friendly greetings. But it really is an amazing event.

Haha, insolence, love it.

Hello MP. Yes all flying wings or planks need elevons for control, and this one needed some reflex for level flight. It would be better to have a proper plank airfoil with reflex built in.

Thanks for the info!

Thanks! 👍

I agree that a strenghtened (carbon rod) large horizontal stab could be there since there is a vertical tail already. I would even make it removable for transport. This would remove most of the reflex

Thanks for the expert tips again. Got me researching plank airfoils now

A few of my pickled onions in the payload would absolutely terrify them!

Chemical warfare is banned! Marmite or nothing 🇬🇧🇬🇧🇬🇧😉👍

I would never put a gyro on these box builds. Not in the right spirit

Airfoil needs camber and reflex I suspect

@@AndrewNewton Ideally, but a Semi symmetrical wing would be easier.....I think you should cut one in foam, you know, a proper reflex section. You could show our Chinese friends what they're doing wrong. I've yet to see them do a proper reflex wing section on anything....🤔😳🇬🇧

5kg payload plus batteries does not seem possible to me, but most GPS flight controllers could handle the mission. You dont need RC signal all the way because the FC could fly the mission by itself.

@Andrew Newton thanks for your reply I am referring to the battery capacity to accomplish the 120 km. I am familiar with UAV. I know how to set up coordinates for autonomous flight

Winged aircraft are more energy efficient than VTOL drones because they can glide, thus conserving energy in long trips. This is why helicopters always had shorter range than winged crafts of the same tonnage.

Maybe the depleted batteries are ejected?

@@franciscoe.9989 Yes you are correct, l talk way above my pay crade.

Our cardboard drones just destroyed a few Russian fighters. Really happy we could help you!

@@tdb7992 thank for your for support ❤

Lighter? Really?

By poster board you mean paper-foam-paper sandwich? Flite Test like (readi board) is what they used for the drone, and does come out stiffer and lighter than pure cardboard.

Foam board is what the CORVO drones are made from.

I think you mean no horizontal stab? Yes planks are odd, but if you get CG spot on they fly. Reflex in the elevons or airfoil provides pitch stability

Might be tricky with just cardboard but worth a try, I'll think about designs

@@AndrewNewton Thanks that will be good. I don't think I would be the only person interested.

Thanks Ol Su, good information

Thanks Hardeep. About 600mm

​@@AndrewNewtonThanks a lot. You have really done a wonderful work 👍🏽

Lucky you, would have been cool to see it in the flesh

@@AndrewNewton Seemed like a normal scratch built rc plane to me 🤷‍♂️

@@bowenbrown yknow I wouldn't be surprised if the actual one has to be assembled using hot glue

Or was it a Boxler?

Would be tougher but this project is all about using model shipping boxes.

proof of concept ... Plus cardboard is ubiquitous and free

The video is the tutorial. Just grab a box and start experimenting

Sorry, no. Just make it up like I did.

Not sure. Can you do a search and let me know?

@@AndrewNewton just found a picture and it looks like it blends over the top of the wing, might reduce your need for speed a little and improve the handling? I think the aileons are tapered too, being wider at the body. Looking forward to seeing mk II 👍🇬🇧

Haha, remember to take your medication

No I haven't. The most I would do with these quick builds is cover with tape.

just put some thompsons on it.

You should ask the video maker for a refund. You seem unhappy with his work

Nice idea, but I'm too lazy

They're already cheap enough that one standard Russian infantry squad mag dumping costs more than the drone, at least if you're calculating using market price for 7.62x39mm ammo.

Control surfaces on flying wings act as elevators and ailerons at the same time.

@@AndrewNewtonwhat kind of rc transmitter are you using. Looks nice and ergonomic for us older folks

Plank plane?

A plane made out of a box. The word "plank' connotes wood.

@@ivanvanogre-nd1sw "Plank" is also the name for a flying wing with no sweep angle. Could be any construction material.

No it's just a rough wing made from rubbish.

It's a very simple design so if you want one, it would be an excellent design to learn to build with!

Can provide the measurements please?

You probably have on in your trash can

Aerodynamic efficiency does make a difference to range / endurance though, which is important in the Ukraine situation. Cheapness is good too -- GPS and autopilots and even inertial navigation sensors are incredibly small and cheap now.

@@BruceHoult and I imagine that drug smuggling will be changing real soon where radar invisible drones carry smaller amounts to scattered preset locations where someone is waiting to receive it. Law enforcement can't cover everywhere so instead of one big 1000 kilo load you'd have, say 500 each 2 kg loads going to 500 different places / receivers, dozens up to hundreds of miles from the border (and scattered along the border too).

@@bobjoatmon1993 perhaps it's time to take another approach to drugs?

@@BruceHoult oh yes, the war on drugs was lost a long time ago and has led to the militarization of the US police (and in my opinion turned a lot of them into jackbooted authoritarian thugs in uniform, and I'm an old white guy Conservative who should be a law&order guy but instead despise the police) So my take is let "evolution in action" take place. Let people use any drugs the want BUT if they injure anyone or cause property damage while F'd up then they don't go to jail, they get a indentured servant collar (with a small decapitation charge in it) and have to work for society for the rest of their life. And not live with any family, they gave that up when they were irresponsible using drugs. Or set up a Purgatory enclave of a thousand square miles out in the west US and dump all the convicted into it where they can be dog eat dog. Make it death to cross back out. Ship in food and water and let them sort out their own society (want to bet it'll be strongest and most viscous rules?). No more prisons, just a fence with automated machine guns and anti aircraft missiles around it. Residents didn't like the US laws and customs, let them make a society on their own inside the boundaries.
