Flite Test - V-Tail Quad - BUILD 

With every build you guys redefine cool. Tack!

Great video David. I liked the overlay at the end with full technical information. Nice work.

Thank you for doing this David, you guys really do listen to suggestions. I want to finish my custom flight profile for the ArduPilotMega 2.5 and share it with the forums. Can't wait to see what you guys do next.

David you did a really Great job On this build & set up !

Finally now we are getting somewhere. I really liked the setup of the kk2 board. I dont yet have a quadcopter but i want one. Thanx guys.

Another fine Flite Test video. Bravo.

You are the best people. I was watching before i got into rc and i just thought "oh thats so cool!" I do say i have probably learned EVERYTHING from you and i keep learning more! Thank you so much and keep making videos! - Nathan R.

Thanks, At the end of the video he show the spec. Can't wait to build it.

Very nice design guys! Working on one with aluminum arms as we speak. Turning out really nice! Will send link when finished!

Very nice David. You have great skills as a builder and pilot. Cheers, John

Awesome build .. I copied this many years ago and still think i enjoyed my KK2.1 board the most

I really liked the settings used and equipment used at the end of the video! thanks guyes

This is really cool, great job David!

Very nice video. I look forward to my first build from the "ground up" of a big Quad. Right now, I am just getting used to them by flying a V949 and a V959 from WLtoys.

Great Ho-To David! This one will definitely be saved!

Loving the multicopter stuff just built my first tricopter its great!

Nice work Dave, et al. Great tutorial on the KK2. Thumbs up brothers!

Awesome vid. Nice to see the exact set up.

that is soooo sick! now I just have to decide if I want to go bat bone tri or v-tail now! David you're making this decision so much harder!

Hooray! Finally brought to GOPRO 3 BATBONE for me! I accept congratulations. :) This is the best camera to fly in my humble opinion. Be testing tomorrow on the field! :)))

Thanks David (crazy swede). Just put my vtail together (from and tri) and i love it!!!!!!! I think it fly's better than the tri. Keep up the good work!!!!!!!!!!!!!

Nice job David, hope you will do more of this kind of videos to help us bilt better quadcopter.

thanks david (and flitetestcrew) really great video :) you guys are the best!

Pretty awesome David. Hope to see some more FPV with that...

thanks for giving us the settings at the end!

very nice quad,

Looks great David. I guess you just start adding things onto the bones. Thanks for the post guys.

Seen some awesome flying with this, great budget copter

Happy Birthday Josh B!

sick setup!

A Derlin 2- or 3-axis brushless gimbal kit would be amazing. If anyone can do it and make it affordable for the masses, it's David!

you guys always use a really nice music scores for the video, i really like it :)

Go on their forums. Thats where people answer questions regarding your setup questions etc. They are really helpful.

That's super awesome! I'm defiantly going to my local hobby store and getting CA! :) Thanks, -Peter

Awesome video guys

You may be right. I have been building multicopters for years and have yet to build a V-tail but I may have to experiment with this. No worries, your English is fine.

Awesome, detailed imformation on the KK2 board is the best ever.. Thanks David, Any chance on the same but with the tricopter.

Nice build

Wow....all this thinking and back to wood. What a nice simple design.

Another great video! I think I know what my next project will be!

Great video

YES, THANK YOU ! LOVE YOU GUYS !

my friend and i just finished 2 days ago out wood vtail quad. it actually flys really well until a prop breaks... i think you could do an entire video on the KK2 board there is so much on it to learn.

Great video!!

argh, I couldn't wait for you to release the video, so I built my own v-tail quad using the plans for your original tricopter body. however, I didn't know that there was a v-tail option in the settings, so I set it up as a normal quad. funnily enough, it few fine! however, it had a tendency to kick pretty badly in the wind, and was difficult to get set up correctly.

I would love to see a video where you have two cameras. One on the quadcopter and the other on the controls. As a noob, I would love to learn how you setup your transmitter and how you make the quadcopter perform the tricks that you have it perform such as the flips and the quick turns.

great vid! keep them coming!

Looks good

wouldn't you want the rotors mounted the other direction? it would be more stable if they faced outward away from each other. if they're facing in won't the thrust cross itself and make a lot of turbulence?

i like the new flitetest guys,

Cool. Didnt know about that throttle setting to make it "launch" level at WOT.

Can't wait to have my fist KK2.0 flight!

OMG! I like that V-Tail Quad! Is the best! I imagine him with a spy camera! To record at parties, beaches, or just for fun! You're the best!

that would be insane. sounds fun though!

Nice video

SUPER VIDEO!!

Very informative video once again,thank you. How about a tutorial on flipping and rolling a Tri for those of us just keen enough to give it a go ( maybe)

I have tried :) thank you

Excellent Video! I would love it if you do an entire video just on KK2 flight tuning! (Put a Go Pro on your head so we can see the menu's) In particular I would like to see you go through the process of tuning one of your Tricopters. I find Quads much easier to tune than Tricopters!

NIce one, cheers

thx for release the V-tail quad :))

If one were to go by their own video and recommendations, the parts list for the frame and parts along would be over $100. I'd like to assume that they would be able to offer it all in a kit form closer to the price range of their other kits. Bat Bone kit - $79 V-Tail Motor Mounts - $4.75 AnyCopter booms - $4.50 Replacement Delrin - Straight - $10 Straight 13-370 Landing Gear Conversion Kit - $3.00 Total - $101.25 This is going by the very video here, not other substitutions or fabrications.

Verry good video, my suggestion is: Make more vids like this, explaining setting.. Like the best settings for acro-flying --> beginner stunting with a quad? how to start ?

Great looking quad! Are there any performance benefits to running a v-tail configuration? My only thought is that some thrust efficiency would be lost as the tail angle causes the rear props to constantly fight against each other in the horizontal axis.

Thanks David, that's cool looking. can you do a video on the setup for your DJI NAZA, I'm still having trouble with mine. mike

It looks bad ass! But also, think of how much extra torque, lift and stability an extra motor can offer over a tricopter, yet still retain the yawwing capabilities of a Tricopter. If Dave is using it over his Tri, it's gotta be good.

Great tutorial, thanks David! One question, what are the lengths of the booms?

I too would like to see some collective pitch multirotor stuff. Either that or some UltraESC.

Exelent, David! Like alwayse! :)

By the way that is funny: I just googled Delrin (the plate material) and found out it is produced about 50 km from my home here in the Netherlands. So when the Bat bone comes in, it has made almost a round trip!

Gotta love the KK2. simple to set up, easy to adjust in the field and flys great. why can't other FC boards have the on screen and buttons idea for field adjustment. Non of this hook to a PC, Bluetooth or stupid stick adjustments.

Make this a kit ! I want one.

mine cost $150 using all hobbyking parts, but I also had the receiver already. I used four dt750 motors, 9x4.7 props, 25a plush escs, and a kk2 board.

Idea for challenge using multi rotors: It starts with multi rotors at night. One person hides a single magnetic object in a field. Each team gets one fpv multi rotor heli, and has to put some sort of light on it, flashlight, LEDs, etc. and a string with a magnet dangling below the helicopter... OBJECTIVE: find the missing magnetic object using fpv and lights. Then capture it with the magnet on a string, and bring it back. The one who finds it and brings it back wins!

Stoked on the video! Any idea what kind of payload this setup can handle? Would it handle a digital SLR?

I like David. I was subscribed to his channel before I got to know this channel lol. Randomly watched one of these videos and saw him, I was like 'WTF??? O_o"

Cool!

David, master of the multi rotor! The settings at the end, are those with zero expo in the transmiter and 100% through?

depends. ranges between 15 seconds for thin stuff to 2 or 3 minutes for thicker stuff

I'm hoping this can be confirmed, but my guess is other than looks, the angle of the tail rotors can help in turning rate, much like the tricopters pivot rotor

Please do a review of the Turnigy 9XR!!

Very nice as always ! I'm going to use the same motors, esc's and board for my bat bone tri. David, you mention you would'n use these motors for flying with the gopro, is that because of the power to weight ratio? Is that also the case when I don't plan to do any acrobatics with it?

I think inverted would be the same or less efficient, you are pushing/compressing onto other pushed air but at nearly 90degress. But if you invert this, then both motors will be trying to draw/suck air from the same space, which is worse.

A build video for the x8 pan would be nice.

I would like to see more vtail quad copter videos

Thanks David for including your KK2 settings. What size battery do you prefer when flying this sized tri / quad copter? I built your tricopter recently and I'm using a 3s 2200 battery. Will this be enough if I want to add basic Fatshark FPV gear to it? Thanks!

Yes, with a considerably sized budget of course but it could be done.

JAY-sus...I remember back in "the day" with a KK2 board. Now you can get a ZOHD Kopilot Lite to do what would have been hundreds of dollars to set up with janky electronics to do half of this stuff. We've certainly come a HUGE leap forward in just 5 years! Hells, I remember having to hand-pick NiCad cells to get a good 4 mins of run time on anything!

Is there a link to a discussion forum of the advantages of different configurations?

Watch at the end of the video around 17:30 and the specs come up on the screen. Speed controller is bottom right corner

supposedly it has better yaw authority over the conventional + and x configurations. Similar to the tricopter. Basically is like a quadcopter with more yaw authority or a tricopter with more lifting capabilities. Fits the middle ground between the tri and the conventional quadcopter

nuito bom mesmo.....

yes, people do it using variable pitch propellers. it's difficult though, as the plane cannot be controlled when in that orientation.

Were can I go and buy all of the gajets you use to build one is it cheaper building it your self or just buying one that's already built ??

Crazy multi rotor lighting challenge... Part 1 cleanest build.. Part 2 obstacle course using only the LCD lights on the multi rotor and on the obstacles part 3 speed endurance battery life.. Fast bright and energy conscious part 4 how far it can be seen from.. And remember crazy lights!!!!!

Is there a good source of information on v-tails? Things like sizing props and arms, having motors facing down instead of up, and just general theory.

What kind of wood are you using for your booms? it looks really nice.

at 40 degrees tilted propellors you only get 76.6% vertical lift efficiency compared to 100% at 0 degrees tilt. I wouldn't rely on this design as it wasted baterry and motor power, regardless of the maneuvering advantages

Looks really stable, like a quad, but good yaw authority, close to a tri. However, wouldn't a tricopter set up be more efficient? Less weight and same thrust if you find a good motor/prop combo (DT 750 with 11" or 10" props). Please do a review on Chad's hex with gimble. Looking at that set up for my next project with APM 2.5.

The v-tail quadcopter will have stronger yaw/rudder performance because the yaw action comes from propeller thrust rather than differential/opposing motor torque of a regular quadcopters and like most other multicopters actually. Its well known that tricopters give the smoothest and best yaw action but tricopter's have increased complexity & costs because of the use of a servo controlled tail. The V-tail should get close to the tricopter's yaw/rudder performance without requiring a servo.
