Great video. I just test flew my HB Y3 fibreglass tri-copter and had all sorts of wobbles going on. Came home and found this video. Now the KK2 board setting makes far more sence. My next flight should have it all sorted. Thanks. UK.

[@BadgerLaser]

thanks for making these vid series - really helpful no nonsense approach......

[@eighthnotch_]

Very helpful video. and Matt really makes it easy to follow along.

[@jgzifly1045]

Matt, I have built two quad copters, one an SK450 and a tricopter. I have the same problem with all three. I take off fairly stable and tri to hover. Between one notch on the stick and the next I am either climbing or falling with no stable inbetween for hovering. I am using a spektrum 7s transmitter. I have the throtel adjust on the KK2.1 board set to 20 to get all the motors to start at once.

[@chris-jones]

Awesome Matt, thanks for the yaw tuning.

[@Nobel0]

wow very nice job guys.. u r awesome , working every day ,thank you for your time in helping us . i would like to be familiar with this great hobby but i am too far :) .. and be funny all the times :) :) Thank you very much again. have a nice day. Yours Sincerely, Abdalhady

[@RcBuddy]

Nice, and good yaw tutorials guys !

[@jflynn12]

Very useful video. Would love to see details on LED setup. I've found a number of confusing instructions and would really like to see exactly how this was set up.

[@terrygtheplaneboss]

Looks great I built the same one and mine is wobleing all over the place

[@zee22311]

Hi Matt!! Can you please post a parts list for this copter..(Shopping List) links and optional upgrades will be appreciated too!!

[@edwarddowling4928]

Trolleydolly130 You need to go into misc settings and adjust the throttle for motors 1+2 (turn them down a bit). Hth

[@Syberteck]

When will HK start selling spare parts for the X900? Nice Tricopter and great price too!

[@olmosm1]

Been waiting for the parts from HKing to make one since Dec/2013 Guess shipment lost. HK has not to date resolved my shipment. Looks like fun if I ever get my parts.

[@gfdfperte4248]

It would be nice if you listed all your settings for this bird with the kk 2.1.5 board. A lot of us are new and there is no manual for this board that I know of. Thanks and good vid over all.

[@scusty1]

That was great l have the same set up and was having trouble with yaw, but now its great thanks Steve. ps' l do have difficulty keeping a steady height while doing FPV ? any sugestions!!

[@Crag19]

Good Info Thanks!

[@oconnor993]

Great tuning guide. I followed it step by step.It all worked well, except I have a real bad oscillation on the ailerons.Back and forth.I tried adjusting it out no joy .I think the board is bad whats your input. Thanks .

[@lordofbasement]

Which setup is this, where can i get those Lights in the front? your work is Awesome helpful, thanks for that!

[@BLEZZ68]

To clarify,according to the KK2.1 motor layout for the tricop motor rotation(prop). . M1= CW--->BLADE1= CW (FL) . M2= CCW-->BLADE2= *CCW (FR) . M3= CW--->BLADE3= CW (BK) all provide lift. . M4= SERVO--->MOTION OPPOSITE TO STICK MOTION(L-R) VIEWED FROM THE BACK.

[@bgates1986]

I want to know the answer to this as well. Seems like mixed reviews. Some sites I've read all 3 props and motors turn same way but the kk2 configuration shows 2 ccw and 1cw

[@bgates1986]

Other way around 2 cw and 1ccw

[@RCShufty]

It doesnt really matter, it will fly no matter what direction props you have, but it they are all the same direction, the tricopter will tend to lean in one direction instead of staying level and the tail servo will tilt more as it has to fight the extra torque of the motors. It flies best when the two front props are counter rotating (usually inwards towards each other is my preference) and the tail can be either (it really doesnt matter).

[@john-paulhopman318]

Thanks for removing the props, though you then went and caught the tricopter. Using the balance plug for voltage alarms and LEDs was a great idea, possible to get some more information on the setup?

[@Trolleydolly130]

Hi Matt. My Tri has a tendency to tilt backwards when trying to take off full throttle and straight up. Any idea what parameter I have to play with to minimize that?

[@joeloalves1748]

Hello..I´m new on tricopters..i´ve already by the x900..but i´ve a question.. about the radio setups..i now that i need confugurate the expo´s..it´s necessary another setup´s?

[@TheScottsawesomeart]

MATT .. MY QUAD GOES TO THE LEFT DURING TAKEOFF AND IN FLIGHT BUT JUST SLIGHTLY DO I JUST ADD MORE I GAIN?? P.S. NICE VIDEO !

[@madsloper]

What is the recommended servo size for this Tri that will fit into the servo mount; part# from HK?

[@jamo2303]

Hi, i really want to get in to tricopter flying and this looks like a good place to start. So i was wondering if you could reply to this message or add to the description a complete parts list, thank you in advance :)

[@HyperJoe]

I'm having a problem and cannot find an answer anywhere,I CANNOT get the Board to Arm. I'm building a Tri-Copter via David Windestål's Instruction and Design and It's all ready to Fly, spent more hours programming and trying to get the KK2 to Arm than I spent in the actual build, what's up with that? I'm really at my wits end here, why can I not Arm the Board, I followed the instructions to a T! Not to mention watching Vids from 20 plus others, with no solution yet... PLEASE HELP!

[@loudmandoug]

how did you connect the balance tab to the voltage monitor? what do I need to do this?

[@MaddMaxxTcs]

With the kk2 board how can you add gps or return home. Or can you with this board..?

[@HomeDistiller]

its funny that no one spotted the pulse jet in the corner lol

[@thercworkshop86]

I need help with the board I set up everything and I still can't fly it what do I do

[@dungeonsound1]

Hey Guys can you do a video on what happened to Stewart's Dead Cat?

[@Redscorpio691]

calibrate your esc's and if it stays use min throttle setting.

[@ba2629]

What is the led lights parts list for that set up

[@Ethanbrower12]

Can I get a parts list of all the parts used to build the tricopter. I am looking to build a tri on the x900 frame and the parts used in the video would be a big help

[@yellowbluerc5047]

probs not in desc

[@tjmmachine]

HobbyKing Live I've built my tricopter but I don't know which motor plugs in where. I'm assuming that M1-M4 are were I plug it in but I have no idea which is which. Any help would be great.

[@oferlv1]

1 left 2 right 3 servo 4 tail

[@basberend]

my motor 2 turns faster then 1 and 3 . where can i change/solve this ??

[@KnucklesRT]

While setting up the servo in the Mixer Editor, my servo starts smoking and dies. Any idea what went wrong? So close to my first flight.

[@yannoche]

Hi maybe you put 'HIGH' for an analog servo?

[@3mincraft828]

when i incrase throttle before lift it will disarm please tell

[@datodaticha6940]

hi.Volt battery requires much?

[@Wamfox]

what were those LED's

[@hanspira1]

Uma caridade , legenda !! seria muito bom...claro em português!

[@TravisBMasterson]

H.A.L. Hexacopter PLease!

[@doddezx]

such a copy of flite test build

[@MrMatVids]

Congrats on copying David Windestals / RC Explorer & Flite Test youtube channels design for a tricopter. Nice to see Hobbyking being original.

[@markgilland9917]

David's tricopter video inspired me to build and fly my tri. This video explains what David didn't though - tuning the KK2 board for a tri. I'm still playing with the settings on my KK2 to get stable flight with self leveling off and this helps.
