Betaflight setup guide from Joshua Bardwell: • Betaflight 3.3 Ultimat...
Say hello to the RCExplorer Bicopter. Yes, Bi as in 2! This copter only uses 2 motors and 2 propellers to generate lift.
Pretty cool eh? But you don’t get much control with just 2 motors, you need something more; Servos! Pitch and yaw are controlled by tilting the motors in either the same or opposite direction
This makes the RCExplorer Bicopter look freaking fantastic flying around. In full forward flight with the motors at full tilt, it’s reminiscent of the V22 Osprey.
The RCExplorer Bicopter is designed to look as badass as possible, and I think we succeeded. The frame is entirely made from high-quality 3k twill weave matte finish carbon fiber. This makes the RCExplorer Bicopter frame lightweight, durable and worth drooling over.
Just picture yourself rolling up your flying buddies and pulling this thing out. Guaranteed instant +10 to street cred and coolness (guarantee not guaranteed).
The sharp-looking backend not only looks like a formidable stabbing weapon, it also makes the copter fly better. The weight is distributed more evenly and the leverage arm is longer, which should make the pitch axis more stable.
This thing is not like a crazy locked in quadcopter that obeys your every command. No, you have to fly this the way it wants to be flown. It is not easy and it will take some getting used to. Tuning is tricky, fiddly and might vary greatly depending on the electronics used (Pre-tuned starting PID’s available for the recommended electronics kit.). You can get yourself into weird situations very quickly and it currently doesn’t like flying backwards.
What it does like is forward flight (both slow and flat out), lazy turns and hovering (as long as it’s not drifting backwards). You can do tricks as well, but be ready for some fun recovery manoeuvres. It is a very different flying experience compared to most other crafts.
Building the RCExplorer Bicopter is also a bit of a challenge. Designed to be as cool looking as possible lead to some awkward spaces. Cable management skills will for sure make things easier, but you will probably still want to curse us a couple of times during the build.

That frame is a work of art david! Like carbon fiber origami!

[@WarChest]

I want to build this frame up just to look at it. Forget how it flies, it’s a work of art! 👊🏻

[@pmm4177]

The mad sweed just doesnt stop making awesome grown up toys! Love this guy!

[@thiyaguramya7836]

Smash

[@philmcgladdery1398]

Best build videos ever. Even the voice of reason sitting next to me doesn't complain.

[@kensmith8832]

Glad to see your time with Flite Test has not been wasted!

[@joshsimmons8178]

I remember my 1st tricopter I saw your 1st tri copter build and later updated mine. Sucks no one really talks about them anymore. planning on making my own v3 here in a bit .. 9 years later

[@SamnissArandeen]

The thing with tilting a rotor as a control input is that gyroscopic precession will also cause a roll force 90 degrees ahead in the blade rotation. The anticlockwise rotor will impart left roll when pitched forward, the clockwise rotor will impart right roll. In your current configuration, yaw left is accomplished by sending the right rotor forward and left rotor backward. The right rotor is the anticlockwise rotor, and the left the clockwise, so the craft will roll to the left while the rotors are being moved. This is cancelled by commanding a little roll right, but by slowing the right and speeding up the left, the dissymmetry of torque will yaw left - and this is continuous while the input is being held. In the video, you did say you were thinking about reversing rotor directions. I think that's worth playing around with. After all, with ACW on the left, commanding left roll will also yaw left with the dissymmetry of torque, and that's already the direction you're yawing to coordinate the turn.

[@engineeredlifeform]

LOVE the little rubber hands,... helps make the point, and are quite amusing. : -)

[@jonnyt1132]

A pioneer of rc models. Well done david! Keep up the awesome work!

[@crucialfarmsurbanandfresh]

Finally I've been waiting for a video for at least 3 years. 😂😂😂

[@zero00tolerance]

He disappeared from the world grow a beard and back with a new drone.

[@Vijimn1]

One of the Best drone building video I ever seen. Thank you Brother.

[@tomrosch8690]

That looks so cool and it seems to fly not to bad. I remember seeing bicopter videos a few years ago and they flew terrible.

[@valiant360420]

David... as I went out to do a little flying today with my 5” quad, I was reminiscing on all your old videos, which are the ones that specifically sparked my dream of flying fpv. That Domain du Planet ( or whatever ), the funjet fpv flights out over the water looking sideways. Good times... Thank you David... and all the best to you. 🤓🤘🏼

[@rcpatapouf]

I love your mini hand 😂😂😂

[@NavJordaan]

I know right!

[@TheBoatPirate]

way better n a chopstick

[@darkswami]

Quick tip for everyone not knowing this: use nailclippers to trim zip-ties. They cut flush so you don't have that nasty piece of plastic with the razor sharp corners sticking out. Especially with the slightly bigger zip-ties. Keeps you from wondering where the bloody smudge on your model/workbench/tools comes from. Oh, and BTW: this is how ALL instruction videos should be! Nice!

[@MrSmartiz77]

I probably will never build that, but I really enjoyed watching this video !

[@yersontorrescastillo1066]

Over all the little hands, really cool

[@NavJordaan]

Same

[@redheron]

One of the most entertaining voice overs for a building have ever listened to 👉🏽🤟🏼 and I freakin love the little pointer dudes. 🤪

[@Jake-pc4fd]

This is big. Mark my words, David, you are going to changes things in a big way.

[@whome7004]

That's a wild looking two prop craft I look forward to seeing what that mind will do next!

[@davidf2281]

Very, very cool. Well done on the design. I'd love to see another video about flying technique with this thing.

[@GrandadIsAnOldMan]

Great build David, I enjoy your video style and your projects even though I have never progressed beyond toy quads.

[@IanTanLK]

Love those little helping hands...

[@mkdzr72]

Another great product Dave came up with. Dude is smart. Thanks for the video!

[@speedrag0n12]

This looks absolutely beautiful lad! Great job!

[@dylanc2806]

the mini hand is literally amazing, so is your advertisement style. "buy this thing"

[@gbresaleking]

I've been telling myself and the wife I wont buy anymore quads and helis ... but no one said anything about a bi copter... man that thing is awesome ! I gotta have one

[@AfterFiveMidnight]

Great tutorial....good to see this out there so kids canplay with something other than video games, this teaches them. Excellent!

[@hugodeanda]

this little copter is RAD!

[@The1TheyCall2-Tone]

I wish I was half as smart as you are. How the hell you figure all this stuff out is beyond me

[@kidpog3d101]

HarlowsKorner 101 i figured out most of this stuff making my own fpv quad from scratch

[@masterdon3821]

Yes. Bicopters are the future,as it becomes easier to make tilting parts. Osprey is unstable, because a lot of weight is outside the center of gravity. But something like a Chinook with wings and tilting propellers will be very stable

[@mahendra4352]

A Terminator Hunter-Killer !!!! Love it.

[@videoleaks]

I love your channel and crafts.

[@Tyrivh]

Mate thats an amazing work, I hope this subject will evolve even deeper because thats new and fresh. You're a pioneer so keep it going :D GJ!

[@CapApollo]

fantastic.... tip.. dont use the iron nuts include with this motors. use aluminum nuts.. they vibrate at certain speed.. i made a video about it.

[@AlexanderShark009]

+ side protection = 2 × efficiency I wish you success!

[@jrayfpv4963]

Dude it looks sooooooo cool! Do you plan to make it fpv?

[@johngabrielherrera8687]

Wow, that was the fastest small rc copter flight I've seen

[@iROMine]

Well you did a goo job making it look as cool as possible!

[@potjnkye86]

oh this is a must. just gotta wait for payday. Thanks david. i always love the odd ball multirotors

[@sergioreis3287]

I like the "hands". Nice idea.

[@aerofpv2109]

Simply superb. Looking forward to your mono copter build someday mate. Cheers -Aero

[@cheif10thumbs]

Hey Genius! Maybe you could invent some props that will quiet this beast down? Love your stuff Dave!

[@CD-rt8wj]

still the best outro animation on youtube

[@mikeoliver3254]

Did a shaven you work at flight test at one point? If so your presentation skills have gotten so much better. Your channel rocks subscribed.

[@hanger9uk]

Love those little hands!!!

[@PESKII]

the little hands tho!!!!! love it!!!

[@eddyfpv652]

Awesome David you did it again

[@RagicaltheUnhallowedKnight]

Would a Chinook design be an option as well? Because it has less weight on the sides, as such the servos don't have to compensate as hard? I mean I've seen those lumbering beasts in action and they are quite nimble for their huge size.

[@Migueldeservantes]

If cool is what you are looking for... perhaps you need to try and make a mock of the Terminator aircraft!! I mean in this moment you have the front head of it the rear end shouldn't be a challenge at all, and it will be something that most people recognize and remember about the movie!!

[@ddegn]

I've finally decided to *GO CRAZY* after being told so many times not to by David. Bla waka waka bingo do finkle zedro beda day!

[@ColtonCampbell]

Have you tried the Oblique Active Tilting method, where the arms angle in ~30deg or so? If i understand correctly this will give you more torque / moment to correct the pitch, and not just move the center of thrust

[@yokesh159]

You deserve a biggg like dude

[@BenHickok]

The frame design really is great. Not sure how the video has any dislikes.

[@biohazardjackson63]

David try soft mounted FC as an experiment also am I able to just use a foxeer f405 AIO for the baby tricopter? Cause it's all I'm willing to use for it

[@BMSWEB]

Absolutely Insane build!! Love this so much.

[@painJm1]

that mini hand is awesome :)

[@andrepacheco6067]

Wow great video! And I learned something new today, carbon fiber is conductive? Holy crap!

[@uber_na_d3r]

FINALLY! it exist! bicopter drone from VIPER TV SERIES !!!

[@adamletchford4018]

That is the frakkin' coolest drone ever 😍

[@johncarold]

I seen you on RotoRiot ×with la drib and this is Great bicopter, Thanks for being nutty-enough to come up with this. JohnnyDRC

[@GregAirsoftFun60]

We want FPV with that,are you going to add it?

[@mihdd]

08:55 BLHeliSuite also runs perfectly on linux using wine you just have to link the usb-device to a com port: "ln -s /dev/ttyACM0 ~/.wine/dosdevices/com4"

[@mrsanti3287]

Hello from Spain. I have read on your website that it is not going well backwards. It will not be for lack of balance between the front and rear weight?

[@OneMarko]

Is that eevblog brymen dmm at 2:27?

[@alecjahn]

Great looking Qua... Tr... Bicopter!

[@The1TheyCall2-Tone]

That looks like it has so much potential to be an insane copter just begging for FPV

[@slaupen]

That looks awesome, need to get that in the future. Only needs FPV and gopro mount. And some LED lights :D

[@MonsterPartsRc]

you should have a centering mark or cutout on the bottom plate and a matching one on the main arm to make it easier to get the main arm centered in the frame... maybe laser etched?... nice bi-copter though..., love the design!

[@EvenTheDogAgrees]

1:30 - Don't bolt down stuff in a circle pattern; always go diagonal.

[@alpemxyz]

What about a new revision of the tricopter? Tricopters are not out yet! (And V5 sounds cool ;)

[@flytechinnovation]

Which flightcontroller are you using?

[@thelennipede9382]

David is back! I really wanna build one now. :) I think if you made it work with 6 or 7 inch props you could fit fpv and maybe a gopro session style camera on it. Or maybe even 5 or 6 cells.

[@bayuizzy690]

you know what... you explaint it very clear.. thanks.. you good.. 👍👍👍

[@TheKumra]

yay a video, I missed ya! More rocket videos are needed :D

[@jeffzhorton]

Very intriguing! Like an Osprey - what's it like in any wind?

[@dan-erikwesterholm8572]

Want that frame with quad motors and anck motors with tilt servos!

[@chintanvaghani2175]

Hi! Great! ! How to make bi copter for just standing an object in the air. Without any remote and as possible as small circuit, for just holding an object stable in the air where it put. Do you have any materials? Or can you help in this regard??

[@TheBoatPirate]

Serious awesomeness! Lotsa progress in the technology. Last time i saw one, it kinda worked. But you got it nailed!

[@Mato0092]

This absolutely needs FPV! :)

[@CORINKERSTEN]

Awesomeness mate great build!!!!

[@lordsqueak]

This is a nice kit , but.... When is the rocket sled knife kit going to be available? ;)

[@davdaya]

tis is a working crazy art.. bro.. u kill it.. cool !! keep it up..

[@Guide504]

Great stuff Dave!! I am still waiting for the DW no prop levicopter, using 'clean outa this world flight' zeroth motor theory.

[@RCLoversan]

Great tutorial, David!

[@David__]

Thanks for sharing David!

[@martinwazhere]

What wire stripper are you using?. Btw i appreciate the soldering tips.

[@thelennipede9382]

martinwazhere it's this old broken one found the the dump behind an old electronics store that he used to work at. Any stripers will work. Just go get a decent quality one and treat it well.

[@jameslinden6304]

When you solder, don't tin wires directly over a circuit board like he does. Get yourself a helping hand device, and presolder all the pads you're going to use before you install the board into the craft.

[@yosayogi539]

I love this idea. Wish I had one to test out. Lol thanks buddy for the vids

[@briandoesathing3478]

i love this so much. i want to take this and make a tinywhoop sized version!

[@mongobaer]

you should think about doing something with the guys of flite test dude. you have some talent!

[@galihargo6997]

Been waiting for this one

[@superbadmofo1]

Has there been an inprovement on BETA FLIGHT for bicopters in the last four years....like going backwards....??

[@SeriusSim]

Looks awesome!

[@lennypaccione8047]

Maybe add one more channel for pusher props in the tail?!!! Work of art though!

[@undefined_account]

About changing motor spin direction. I thought blheli perform change it through UI. Or ESC doesnt support blheli.

[@DAKOROB]

Do you think you can turn this into a tricopter by adding a tail prop..ad leaving the to tilt arms in the front for yaw.?!. I know it can be done but don't know how.

[@jae_tv2666]

Most detailed vids. Thank you for that bro...

[@ashleycruz7730]

so this Bi-copter will have more flight time compare to a Quad-copter using the same battery?

[@hugorosas1490]

eres un genio... te amo seas quien seas

[@СергейЭдган]

Это самое крутецкое творения, что я видел!

[@marcusmckay8120]

Curious why dont you do a tri copter with the bi copter front motors so all 3 motors move and see hoyw that fly
