FPV Peace Drone v2
HTML-код
- Опубликовано: 29 дек 2011
- The Peace Drone, designed for FPV ("first person view") flying. Uses the simple construction Armin Wing airfoil. It's very easy and forgiving to fly due to the canard configuration and low wing loading. It flies slow, glides well, and is very difficult to stall. The pusher prop stays out of the camera field of view. Weight is 1300g with basic FPV setup and single battery for 10 minute flights. Easy to build out of 4 sheets of Readi-Board from Dollar Tree, hot glue, and packing tape. All construction cuts are straight and square. 1100kV motor and 10x4.5 prop gives about 800g of static thrust. It collapses to a size of 8x8x32" for storage and transport.
Named the "Peace Drone" in contrast to the Predator, Reaper, etc. military drones. I'm kind of bummed by the bad press UAV's are getting lately by killing and spying. The Peace Drone is made for FPV fun only.
The FPV setup is a 200mw 5.8gHz from Hobby King with their cheapest 1/3" CCD Sony board camera (no case) and stock antennas.

Started my new build yesterday afternoon and finished this morning and would maiden it tonight except N.E. Oregon is covered in rain today.
Ed, thanks again so much for this design. I have a project in the works that this is a great canidate for, I will let you know more as it pans out.
I love the "low tech" "low budget" "high simplisity" "high modularity" "easy field repair/replace" concept. What the foam board lacks in duribility this design makes up for 10 fold, all your designs do!
Brett
Continued; I am using almost all of your overall PD V2 dimensions with the exception in the wing cords being 8.25" with 2" control surfaces, totaling 10.25".
I built the main wing into one piece with a continuous 1/8"x5/8" poplar spar while the front canard has a spar of .5" thick pink foam insulation board to keep the weight down.
The fuse is 3.625" square od x 45" total length.
Thanks again for sharing the PD V2 with the world bra!
I have to tell you... when the stabilizayion is setup properly... wow ir can be a dream. Plane flies perfectly stable and straight in even the worst of wind. Flown in 30mph winds and plane flies like it calm. Definately takes some of the anxiety of flying far out of visual line of sight.
I recommend 3/4" +/- throw for both elevons, no differential, and 100% for aileron rate, 50-75% for elevator rate. These elevons are much more authoritative at pitch control than roll, hence the different rate. Also as a result of this, differential tends to cause a very uncoordinated (slipping) climbing turn when simple roll control is input. Use equal up/down for elevon travel for aileron mode.
Another excellent instructional video with well anticipated detailed information.
Awesome meticulous description of an amazing design 👏
@ExperimentalAirlines thanks for the help. I'm building two of these. One for myself and the other for a friend. We're both newbies to the hobby and dont want to spend a lot of money so we saw this video and loved it. Only thing that stands in out way is the gyro and programming the remote of our choice., the Turnigy 9x.
A Beautiful piece of engineering.
Just two words are enough Ed --- Brilliant design !
I like using two 2200mAh in parallel, which weighs about 1600g AUW. I have flown up to about 2000g with three batteries, but I found some additional internal stiffening would be necessary for stable flight. Stay tuned for improvements.
Thank you, very intelligent fpv Project, congratulations!
Man i wish i would have been doing these planes when you were still into it!im just getting into building and flying DTFB/ EA type fixed wing aircraft! Thanks for all of your work making these avaliable to all of us who want to build and fly!!!
Something is coming. Stay tuned!
Yes, good point. Well, most of the force against the latch mechanism is shear, so the "free" magnet should theoretically sit down in a recess in the foamboard, the side of which bears the shear force. The "fixed" magnet should only need to hold the free magnet down in that recess. I just stick the fixed magnet to the free magnet, fill the hole with hot glue, and push both magnets down flush with the edge of the hole. Maybe epoxy would be a good idea for your cold situation.
Aileron differential. Upgoing aileron (or elevon) travels up more than the downgoing travels down. It's good on conventional planes as it places more drag on the inside wing in a turn, so it tends to help yaw the plane the same direction as it's rolling (a "coordinated turn"). This works great on straight-up ailerons. With elevons it's tricky because they are acting as elevators too, so any aileron differential also becomes elevator differential, which can cause weird behavior.
NICE JOB!! Happy New Year!!
Great work! Thinking of building one of these.
Great videos and super nice design. I am going to have to build one of these peace drones. I am thankful for your instructional videos. Keep up the good work.
Ed, what's new?
Did you hear the news recently? The Peace Drone is due to land in Yucaipa CA soon. Yes it's true. I know, it's amazing!
Ok, I'm building one. I started on the bird at 4pm today and I have completed the wings and fuse sections by 9pm.
I must say, I am even more impressed with this folding technique now that I have tried it out for myself. I am now sure that I will build a heavy lifter with a 72" wingspan and a 12"+2" cord using the 1" aluminum shower pole as a spar.
@mtbRAF It ends up being a 3x3" inside tube, minus any reinforcements inside the fuselage, so I take a piece of foamboard of that dimension (for example, 3+3+3+3=12) and roll it into a rectangle to serve as the coupler. It can take a couple of tries to get the precise degree of snugness that you want. I will include more detail on future videos.
The foamboard is 5mm extruded polystyrene, like Depron but lighter, and it's faced with a thin paper which can be peeled off. The majority of foamboard has heavier paper that is difficult to peel. I've been told that Riot Art has been known to carry an acceptable foamboard which is not perfect but usable and about 30% heavier. Depron which has been cleaned with alcohol and pre-taped with packing tape can be bent similarly if you "crush-score" the folds with a blunt instrument.
real good videos
thanks for some great info
went out and bought 10 sheets form board
i will be building something soon
will post it on my youtube page
thanks again for the great ideas
thanks!
Hey there question for ya? I watched your wing build video and understand the use of the cf rod for support ,you explained the 3 weaknesses also. On this wing at the start of the video you place the rod inside of the wing. what i dont or didnt see was what else did you use to keep the tailing edges together? you put the rod in then placed the wing on the body and used rubber bands,is that all ?
@letmeplaymystrat Good eye. Yes, it's a rate gyro on the left elevon only, oriented to correct roll. Aerodynamically it works very well. There are many caveats about it though so I left it out of the video content. I have to let it arm with each flight, which takes a few seconds. I took off with only the right elevon once and luckily made it back alive. Differential on the elevons must also be set to 0%, but it actually flies better that way with or without gyro.
Would you recommend this for a first time builder/flyer? By first time, I mean I've never flown an RC plane before.
How thick is the depron you use for the wing tips?
@GenrlSt Yes, that's perfect. A little leggy, good for speed, but if you motor will handle it efficiently it's probably a great choice. 11x6 good also.
Awesome plane, great design, maybe someday I'll build one of these ;-)
Yes, that kind of fits with my findings. The two wingtip vertical stabilizers of sufficient surface area seem to be adequate with the CG placed at least 15" forward of the firewall, ideally 17". Would not fault you for adding an additional fin. Your choice on the motor. I like having a little extra power to get out of trouble so 200w is my personal base minimum. Hope to see yours soon.
Hi, Is the CG constant at the location of the main wing whether I use a camera or not? If I am not using a camera, and want to keep the CG constant at the location on the main wing do I have to attach weight to the front end equal to the weight of a camera and associated camera gear at the location of where the camera would go?
Canards tend to unstability in yaw (I have been reading), and one reason that Rutan's successful low-speed models have swept wings is to move the tip sails aft to give them more moment, ergo authority. I, too, notice a lot of Dutch Rolls on builders videos, and am considering adding a central fin, as well as making the fins all high-aspect ratio.
Ed, I want to make a super light, non-FPV vs. just to play with the canard concept. Still reccommend the 200-300 watt motor? Or could I go lighter?
Thankfully it couldn't be easier for this plane. I recommend using elevon mixing on your transmitter if it has that mix, and it is one of the most common mixes found on even basic "computer" transmitters. Use straight elevons, as a mix of elevator and aileron channels, with no differential. If necessary use a better-quality (like GWS) onboard "V-tail" or elevon mixer and set the individual channels on the radio for equal throw. Instruction manual for the mixer and transmitters will describe.
This 2836 1100kV motor info links placed in notes. This gives good power, moderate efficiency, good for casual use or shorter FPV flights. Other guys are having luck with 900-1000kV 35mm diameter motors of various types with larger 12" props and 3-blade 10" props and getting better efficiency and flight times.
Cool - the only stuff i can find here in Australia is foamboard used in picture framing. The stuff is used as a backing for artwork. It seems to have the paper backing you described.
Thanks for the reply! I also notice on canard aircraft they avoid mounting the canard at the same level of the wing, usually higher. Do you notice any angles of attack where the airflow from the canard interferes or creates a slot effect with the wing?
I like MrWest's motor mount for unimpeded air, but he had a lot of trim issues. I am considering a carved balsa fairing aft with center mount motor for clean air and avoiding asymetric thrust. Do you see issues with that?
I am also considering
I wouldn't worry too much about the internal fuselage stability, since it's just hanging from the wing in flight. You could certainly brace it if you like, but it's not likely the flight problem. Are your vertical stabilizers pretty large, like 1 chord long and 1.3-1.5 chords high? They need to be pretty generous since they are only effectively about 13" behind the CG. Keep in touch if I can help.
I love your videos, the one from Burning Man was the best. Please tell a newbie what UBEC you have in the Pease Drone v2. I have other parts on order and am looking forward to building one just like yours.
..."Grippiness...?" Is that a technical term? lol:))
I LOVE to watch your videos, Ed!
I like the way that you have 2 x swappable FPV/cam "pods" for the nose, but is there any chance of you making a tutorial on how to make the mechanism of joining them together, or making the smaller "tube" that slots inside the man fuse from the nose pod?
this looks good, what weight and lipo can it hold and fly with?
Why did you get away from control surface on canard on V2? my OSD uses a stabilization module. works great with elevator/aileron setup. terrible when used in elevon setup. Would the CG need to be move if i bbuild with canard with control surface?
@cathburgerqueen It's all 5mm Readi-Board, commonly found at the Dollar Tree store. Other types may work but many other brands with heavy paper facing will not work.
Awesome upgrades to this plane. Love the single connection between the wing and the fuse. I see you have a gyro on the opposite wing. Are you using it for stability on one control surface? If so, how is that working on for you?
does the motor mount have some down thrust to it? I've seen some planes of this type with some down thrust added and i was wondering if this plane needed any.
thanks anyways, i enjoy your vids :)
I think it would, i buuilt the baby version and with the motor with 0 thrust angle it pitches up above half throttle and thats with the canard flat
Hi there, well I've nearly finished my build. Will have to make a slide show or something as I came up with some interesting features on my swept wing version. I upped the power with a 160gram 910watt motor and parallel battery setup. One last thing I was thinking of is rudders, as it seems a little opposite rudder can reduce all that roll when turning, an 'elevons only' effect that I don't think complements some fpv footage. So do you think rudders will work on the vertical stabilisers? Rudder
Can you explain your wiring set up in the wing? How did you connect everything with only one wire?
Thanks
Noah
Hi. Ok I got a bunch of build materials and am starting a couple of build designs. Do you thing the peace drone would work with an EDF? Maybe you could have something a bit like cooling scoops to direct air into the rear half of the fuselage. Efficiency losses? Also I am thinking of making the wings slightly swept with the same construction method. The modular system you designed is amazing! So portable. Thanks.
Only for simplicity and reducing number of servos and wiring. It actually worked fine, maybe a little better with canard elevons. From an autopilot or autostabilization standpoint I bet it would work better with canard elevons. Are you using Nova OSD 1.5? Me too, just haven't hooked it up yet. I could use any wisdom you have.
Very nicely done. That design must have required much thought. I wish I could build one. Would you be posting any Plans for any of your designs?
Really great job, can i know where is the cg of this plane?
@nieder99 I set my ESC brake to "on" and always glide in on zero power to land. The prop does occasionally tap the ground upon landing but it immediately bumps up out of the way. There is some trivial scratching of the prop tips after about 30 flights landing on asphalt. For my purposes installing a new $2 prop every once in awhile is simpler than landing gear.
Hey ed! having trouble with my v2 peace drone, flies straight once i throw it, but it wants to flips right over when using the ailerons. Thinking it may be with the weakness in my square fuse. I havent put any bracings in it so kind of moves side to side when sitting flat on somthing. any ideas from your own experience?
I see you have a gyro mounted in the main wing. Is that the only gyro you used? I asume it is for roll only and it works well with the elevon set-up?
@epet52 Yes, only one gyro, oriented to sense roll, and connected to one elevon only. It works very well to smooth out the roll axis for FPV. I'd rather have both elevons respond to roll but that requires two gyros and more complexity. If not for the FPV aspect I probably wouldn't bother with the gyro at all.
Excuse my ignorance, but how do you determine where the CG should be if you have a canard wing?
Looks great! Thank you for sharing! Will we see some flight videos of it soon? Have you conducted range testing?
@ExperimentalAirlines Thanks for your quick reply, great info. so i guess it's trial and error to get the right "snug"-ness then. great concept for the entire drone. well done :)
That's just awesome!!!
Love it and I'm going to build one of these peace drones.
I'm starting FPV now.
I will let you know the result.
Thanks for sharing this with us all.

(nunol) in the forums.
(ngalop) in the tube.
Rudders usually being in the centre?
The salt cells I got were from friends and a former acquaintance pool guy who I lost touch with. Sorry no recommendations. What are the specs on the motor: KV, watts, thrust, whatever you can tell me.
my motor suports up to 11x7 prop. Do you think this is enough?
which gyro are you using?
Can I use/get away with using 2 9g servos in each wing? You are using one 19g so two 9g's are about the same Maybe even split the elevon surface to do flaps? or would flaps throw things out of whack because of the canard plus rear wing set up?
Thanks
Noah
do you have any issues striking the prop on landing?
so really old video but looks like a great stable plane. If boss man and legend still reads these is it a good frame to still build. As it seems stable have a great glide and carry good loads.
Having issues getting off the ground and this looks perfect. I went for planes that need far more than beginners to fly them, FpvRator V2 and the Opteera.
ive built the baby version (40" main wingspan) its very easy to build, i did it in about probably 16 hours taking my time, although if your good and quick you could do it in as little as a few hours>
NOt entirely sure its a beginner plane, you might be better of with the noob tube.
Ed, I am in the process of building my peace drone, I have an e-flite power 25 motor lying around that i think might work... Your thoughts? Also which pool supply company did you get the old salt cells from, I'm in the phx area and I can't find anyone to hook me up with a bad cell!
That ought to work nicely, with a big prop on it like a 12x6, if you're using 3S battery pack. Probably actually be pretty efficient for long flight times.
Did you use any scientific methods to choose the wing chord? How did you come up with that measurement?
what do you mean by differential?
It flies quite well but does roll a bit in the wind. It's not hard to fly but the HD footage is kind of jumpy up around the 10mph wind zone. I just posted a video where I flew some calm and some windy if you want to compare.
For first Happy New Year! I like all your works. But i wonder that "Piece Drone" hasn't any art of steering on front wing.
@coolwaterhubby I just cut the cards with scissors and drill the hole with a piece of the pushrod chucked into a Dremel. See my "Armin Wing" video on servo installation for more details on that. I use those gift cards all over the place for reinforcement. For the control horns I actually started slotting the control surfaces and pushing the horn down through the control surface, top to bottom, and gluing sufficiently. It's very strong.
can anyone give me the control throws there using? also any tips on the radio mix used?
I use an ordinary 5a UBEC from HobbyKing, though honestly using two 9g servos and the usual choice of receivers, a 3a one would work, or even the onboard BEC on the ESC if it's trustworthy and at least 2a but preferably 3a.
Hi - these planes are AWESOME !!! Do you know (or anyone else) what the equivalent of $board is here in Australia ? Is it the same as Depron or Corflute ? Cheers
@epet52 Probably no formal plans, but plenty more information to help other builders. It's so easy to piece together all straight, rectangular pieces.
@coolwaterhubby 10 minutes with board camera and one 2200mAh pack, 30 minutes with 4 packs. Probably 10% less with GoPro onboard. OSD should give me confidence and a duration advantage. Right now I'm pretty conservative with the timer.
@GenrlSt E-Sky EG200A EK2-0704, just an old rate gyro, nothing special. There are much smaller and plenty cheaper ones now. You might only have to contend with the extra lead for gain, but you can put that on a switched channel too, which might work to your advantage.
I don't get it Sir...? No rudders how do you turn ..? Serious Question ?...?...?
Im working on one now but I am going to run a twin motor wing mount style, no fpv, but I will have a few cams on it, just want a nice slow flying BIG dollar tree foam plane...just building with extra parts I have lying around, urs is awesome by the way... :)
She's had a name update. See the new series on this plane on this channel.
Felicitaciones excelente, quisiera obtener los planos y lista de materiales. Gracias
@MyGeekShowdotcom Yes, those are the very next orders of business! Better flight video with GoPro on the next installment and going to try full range test with skew planar and helical CP antennas. I will definitely report on that. I've got a 2.4gHz booster to install on my Spektrum too. This is far from ideal, I know, but I'd like to keep my trusty DX7 for short range, 1/2 mile stuff. I'll work up to the long range mHz gear sometime.
@ade4200 I don't think EDFs are efficient enough to get the most out of this design, although they are cool. Swept wings are a nice stylistic touch. I doubt you would get much in the way of improved performance at the low subsonic speeds we fly. Maybe a little bit more stability. It would look cool though. Go nuts with it, whatever you want it to be - and be sure to share pix and video!
Hey guys,
I'm thinking of my next FPV plane after the trusty old SlowStick,
How is this thing in wind?
Cheers!
Dion
You need elevons, so each servo has its own lead to the receiver.
Sure, hit me up any time. You can comment, send a PM, or join the conversation at RCGroups, Foamboard Scratchbuild University thread. Great to hear from you.
Send video if you can. I have had the wing shift if not enough rubber bands and/or no "frictiony" substance between wing and fuselage, like rubber bands or weather stripping. Be sure you have no aileron differential programmed in, and try to avoid any mechanical differential by keeping the control horn holes as close to hinge as possible. If it's actually part yaw instability be sure the CG is (ideally) 2" forward of the midpoint, so 17" forward of the rear of the fuselage.
Your planes are truly amazing i just wish we could get dollar tree foamboard here in the uk i know there is alot of people that would buy it.
@ade4200 I wanted a moderately high aspect ratio wing (10:1) with a thickness ratio approximating many gliders and general aviation aircraft (11-14%). I hoped this would give good lift to drag efficiency under power and in glide and would offer decent stall characteristics. So far so good. Sorry nothing more sophisticated than that.
@GenrlSt You know what, I'd skip the gyro, especially if you're not doing FPV. It's probably not worth the extra effort. Get 'em flying nice first then start the customization. Be sure to make your vertical stabilizers big enough, keep the CG well ahead of the 15" mark (13" behind the front of the main fuselage tube is much better for maiden) and don't make the nose pod any longer than you need it to be. PM me if you need any help.
Hope that answers the question. If not ask again, with more details, or PM me.
I don't have a friction type substance between the wing, so it may be moving when the left or right aileron goes up. I will have to try that, and i have video of it, i will find it and let you know. My stabilizers are cord length wide and alittle larger in height.
@EA... I'm using Greentree OSD with Gardian Stabilizer. I used it on my Cargo design plane. it was a convention setup. the I used it on a delta wing. The Gardian did't like the elevon setup. Reacted to quickly on toss and literal flew it into the ground before I could get my hand on the stick. plus... I was much more of a complication to setup the fireware for RTH. So i abandond the project. I prefer a simpler vapproach. Your design definately fits the bill.
have you flown your drone in some wind? I did.......really wierd flight!!
old post but i just did that yesterday in 15mph winds gusting to 25, certainly made for easy launch. I could get it stationay when into the wind
