The Hobbyking SK450 is a brilliantly designed 450mm quad frame built from top quality materials. The main frame is high quality glass fiber while the arms are constructed from ultra durable polyamide nylon.
This quad not only looks great, its very well thought out as well. Assembly is a breeze with pre-threaded brass sleeves for all of the frame bolts, so no lock-nuts are required. It utilizes one size of bolt for the entire build, making the hardware very easy to keep in order and only requiring one size of hex wrench to assemble.
The SK450 also has an orientation feature which is quite clever. It includes a yellow foam ball which you install on a carbon rod that mounts between the frame arms. This not only acts as a bumper to prevent running into obstacles, it also makes for a great orientation aid to keep track of the front of the quad while flying.
We offer a full line of multi-rotor electronics such as multi-rotor control board, ESC & motors. It has never been easier or more affordable to get a quad in the air!
Features:
Built from top quality glass fiber and polyamide nylon.
Pre-threaded brass sleeves for all of the frame bolts.
Yellow orientation ball to keep you flying in the right direction.
Easy assembly.
Specs:
Width: 450mm
Height: 80mm
Weight: 300g (w/out electronics)
Required:
4 x 28mm 1000~1200kv (or similar size/kv)
4 x 15~25 Amp ESC
4 x 8x4~10x4.5 Prop (2CW & 2CCW)
1 x HobbyKing Multi-Rotor Control Board
1 x 1500~2200mAh 3s 11.1v Lipoly battery
Your own radio and 4 channel receiver

Good job! I am a beginner trying to build and set up a quadcopter. I have watched a lot of videos. This series is the best I have seen yet, especially the section on setting up the P and I. Thank you for all the effort. I have given you a THUMBS UP and will subscribe.

@pjmamanflightmonster526 10 лет назад

Hey Frank, thanks for the videos. I got this quad a couple of weeks ago and have been having a blast with it. I hooked up a Fat Shark Teleporter FPV system and I have been getting some great aerial footage. The tuning tips helped me out a lot and now I have a basic understanding of how to make adjustments to get it to fly well. Hopefully soon I'll get the nerve up to fly with the goggles only and not the little 7" screen while peeking up to see what's going on. It's a bit scary when you can't see anything else but about 32 degrees field of view :) Keep up the good work.

@adr14n87 11 лет назад

thanks a lot for such a nice tutotial.It's helping me a lot with my PI settings

@GeorgeBonez 11 лет назад

I think so too! Man just having your consensus on this makes me feel better and gives me the balls to tweak these settings. The reason I am so timid on stuff like this is because I recently asked ten thousand questions on youtube about “Clearing” my RadioLink TX & the only 2 people that I found that had one said “Sure man do it”. Well nobody told me that ch 1 is RVST so you can imagine what happened when I tried to arm it 4 the 1st time! lol Not pretty dude! Thanks for your help man.

@DiehardRCaddicts 11 лет назад

The esc firmware was not flashed. All the parts used to put this Quad together were used right out of the box with no changes made. Nothing's been changed yet because so far I'm happy with the way it flies.

@FangarJim 11 лет назад

Nice work Frank. Rolf has posted the 1.5 Firmware update which addresses the auto level issue. It is actually designed to right the copter, should it become inverted or out of whack. He does some great demos where he tosses the Copter into the air like a frisbee and the auto level sets it up right. Very nice. I have flashed all my KK2.0 with the 1.5 version now. Cheers.

@pradeepdasgupta1 10 лет назад

I think these three videos are absolutely fabulous! I was struggling with my first quad set-up before i chanced upon these videos. I ran thru them in detail and followed the steps every bit of the way and surprise of surprises...I managed a successful first flight straight away - with the auto levelling on! However, my quad tends to flip to the left with the levelling on. Any valuable tips? Anyway,congratulations on a video excellently made. I wish there were more such videos for other models with other boards.

@luvthemullet 9 лет назад

hey! great video series!

@DiehardRCaddicts 11 лет назад

Tom, yes if you get everything listed in the video information bar you should have everything you need but like you said you will also need a control board like the kk2. The link at the very bottom takes you to the accessories where you can choose the standoffs for the control board along with a battery strap and any extras you want.

@cam343 10 лет назад

I have the same issue with the Auto level on the same frame. You can tune the auto level trims as per: KK2 Autolevel Tuning and Explanation Still trying to find decent and P & I settings, just doesn't feel locked in yet for me.

@Skydive4ever 12 лет назад

I just got mine working a week or so ago, the Autolevel is really mushy on the sticks, I am playing with the gains and seeing if I can get the Autolevel to work better, if i see any improvement i'll post it here. Thanks again for the great review :-)

@DiehardRCaddicts 11 лет назад

No, all programming is done through the Menu using the on board LCD screen of the KK2. That's the nice thing about this one, you can easily make setting changes at the field without the need of a computer. Please watch the part 2 video on how to navigate the menu and set everything up.

@Unmedicated_Moments 9 лет назад

Hey man, whenever I try to fly my sk450, the quadcopter only goes up on one side. This results in the rotors getting torn up on the side that stays on the ground. Please help

@Aviationrcfpv 12 лет назад

thanks for the great vid

@edwardsiyavong7860 10 лет назад

Hi,diehardRCcaddicts , this is very helpful video and thank you for up loading it.could you give me some ideal how to hook up power to turnigy 9x 8channel receiver through the kk-2.0v control boad?.I thought I hook every thing right , but there is no power coming through the kk-2 boad to receiver.How can I solved this problems..thank you.

@DiehardRCaddicts 11 лет назад

Not sure which version comes installed but that is the version we're using. We used it as it was right out of the box with no firmware updates.

@creativemind4165 3 года назад

great drone... i make the same drone but in my case drones motor rpm increasing without incrase throttle so what i should do ?

@Rip1Outdoors 10 лет назад

Thanks for the videos they were very helpful.How did you setup dual rates and expo on your radio? Did you just set everything to 0 and use the board stick scaling? Thanks

@DiehardRCaddicts 10 лет назад

Set radio settings to 100% then adjust stick scaling for high rates then you can set low rates % on radio dual rates.

@DiehardRCaddicts 11 лет назад

Stick scaling is like having adjustable rates on your control throws. the higher the number the higher the rate of movement. Sounds like you need to lower yours if that's possible with your older kk board. I don't know because I've never used one. P and I has to do with gyro gains. You can fine everything you need to know if you click the link to the KK2 forum on rcgroups located in the video information bar below the video. That's how I learned a lot about it.

@carr869 11 лет назад

Well DiehardRc I've placed my order and I guess I'll be building in a few weeks. Thanks for your help. (Tom)

@JonathanRichey 10 лет назад

What size battery did you use on this flight test and how long were you able to fly it?

@davidlee50 10 лет назад

what goes in the first level plate? I notice the battery is under the quad but it is too dark to see the plate over it. Nice build series btw.

@GeorgeBonez 11 лет назад

I think I have been to that forum before but they only talk about the KK2 and nobody ever seems to know anything about the KK1 but I will take your advice and give it another shot. Do you know what an EPA (End Point Adjustment) is for? Could that be a similar term to (Stick scaling)?

@DiehardRCaddicts 11 лет назад

Sounds like you need to adjust the minimum throttle values in the misc settings. This is covered in the part 2 video if you skip to around 9:10minutes in the video. You want to adust the value up a little at a time till all esc start up at the same time.

@trevorms 11 лет назад

Nice series of videos on the SK450. They have helped me build, setup and fly not only my first quad, but my first RC anything ever. I flew my SK450 for the first time this weekend. I noticed that it would loose altitude when pitching forward but not when pitching backwards. In fact it would gain a little altitude when pitching backwards. Do you have any recommendations on what may be causing this or pointers on what I can trim to fix this issue? Thanks for the great videos.

@TheSamarthKirloskar 11 лет назад

I had the same problem... This means that you havent calibrated your ESCs yet. To do this follow the instructions from the online manual. Hope this helps! Happy Landings!

@cup_and_cone 10 лет назад

Frank, did you ever bother with trying to adjust the auto leveling or attempting to flash the KK board at all?

@sourabhpoonia7168 6 лет назад

I am trying to fly my dji 450 quardcopter .when it up in the air it sudden stop from one side and folen on ground. Please help me

@DiehardRCaddicts 10 лет назад

This is a good board for this quad but I can't say if it is the best, there are too many other ones out there. As far as flashing the board I still have the original firmware that was on the it when it shipped. I'm happy with the way it flies so haven't changed it. I don't fly using the auto level feature but it still works fine and is very stable.

@VEproductionTV 10 лет назад

great video! good! but i've a question... i've one gopro hero 1 motorsport and this weighs in around 200g you think i can mount on this quadcopter? thank you so much! :)

@wheresmichael2194 7 лет назад

probably. this is a pretty powerfull quad

@DiehardRCaddicts 11 лет назад

They are for adjusting the gains on the gyros. Please do a search on RCGroups forums for more details on P&I gains.

@carr869 11 лет назад

so if I buy all the parts listed I can build a quad copter like that one? I know I need to order the KK2 board also. I kind of wanted to make my own frame just because I think it would be fun. You made it look pretty easy. Thanks for sharing this with us. ( Tom)

@GeorgeBonez 11 лет назад

I am a beginner so will you please explain what the purposes of the I & P gains are for me? I am flyimg the old KK board and I CAN keep it in the air but I dont know what to adjust to smooth-out oe slow-down the stick-response! My quad is on CRACK right now and if I barely touch the stick, it GOES NUTS! ((help)) ?? If I could just slow the stick-response down a bit I would be ok but I dont understand the terminology of what I & P means etc :(

@vasuchhabra5989 9 лет назад

Hello sir.I used radiolink 6 channel rx and tx and used kk2.1 as flight control board.I can't find my problem but my quad flies sideways rather than flying vertically.please help me to solve this problem!!

@DiehardRCaddicts 11 лет назад

EPA (End Point Adjustment) is the end point of travel or movement so yes I would believe this is similar to stick scaling.

@DiehardRCaddicts 11 лет назад

I've had one go bad and replaced it. Haven't had any other problems since then.

@DiehardRCaddicts 11 лет назад

Not quite sure but I get about 5-7 minutes out of mine with the setup on this quad. Your motors are smaller so should get better run times depending on the prop size and pitch. I suggest using a LiPo low voltage buzzer the kind that plugs into the balance plug and buzzes loud when you hit a certain voltage per cell. Hobbyking sells them just do a search

@gobiandreson3111 6 лет назад

Which flight board are used 2.0 or 2.1.5 ?

@parichyagautam 11 лет назад

i have the same board but at 1.2 firmware . The moment i give throttle it just Tilts and on giving more intense throttle it just flips !! .. any help on that , i have all the ESC , Sensor calibrated and all the other usual stuff is done .. any help on this ?

@DiehardRCaddicts 11 лет назад

I don't use the auto level but I hear you can fix it if you update the firmware to 1.5 version. I haven't tried it because I'm happy with the way mine flies and don't want to go through setting everything up again after flashing the firmware.

@timbo400 11 лет назад

Yes, that happens with mine too. Turnigy plushes?

@indianinvention2698 5 лет назад

What pi setting Is best for stable

@DiehardRCaddicts 11 лет назад

Did not paint them. It came with all white arms. The red ones can be bought in the frame parts section for the SK450 on HobbyKing website. They also have them in black or green.

@agungwaw 8 лет назад

can i use this kk board to racing quad? thanks

@shekou 9 лет назад

hey diehardrc on what/how did you mount your flight controler on? got the same frame but you've got yout fc on the top where i've got my lipo. how/on what did you mount your flight controler? do you have a kobbyking link for me? cool videos :-)

@DiehardRCaddicts 9 лет назад

Gerd Specht I used nylon standoff spacers with nylon screws. Use the link in the video information bar to "Multirotor Accessories" on hobbyking site. You will need to order both the M3 sized spacer and screws. If you get the treaded spacers you will also need the nylon nuts. I used the tapped ones that only need the screws.

@ocramocariza 11 лет назад

When I enter the Menu on the kk2 (version 1.2), the ESC beeps around 1 beep per 2 seconds. Is the normal?

@TheSamarthKirloskar 11 лет назад

Hey! I have a problem, hope you can help! I use the same KK 2.0 board on my quad and the problem is that every time I power it up and get it ready to take-off, upon giving throttle motor no.2 doesn't start immediately....it glitches and then I need to spin it myself first before it start opperating fine. hope you can tell me how to resolve this issue! Thanks in advance! Happy landings!

@gforcefoamy 11 лет назад

if it wonders alot in self level mode should we recalibrate on a better level surface but make sure that the board ITSELF is level alone and it should work right? or? mine wonders alittle so id like to fix that to perfection can you help please??real help and kool stuff is why ii subscribed hk should help you help us.

@CowneloAlvaroid 9 лет назад

Looks like a nice quad for the $ hobbyking has a prebuilt for under $200 but I have 2 questions 1.what are the flight times with the 2200mah battery? 2. What's the stock range? Oh and this would be my 1st real quad other than my hubsan x4 so advice would be appreciated.

@shekou 9 лет назад

bout 12-15min max

@wboy3 11 лет назад

did you have to program the kk2.0 baord on computer?

@pinoydad_0811 11 лет назад

i have mine for a while and not a week ago or so i updated it to 1.5 and the selflevel is working very good ..i will make a video soon as i get done charging ..so stay tuned to my channel..

@GeorgeBonez 11 лет назад

I am waiting for my new props to come in right now so I am going to balance my motors as I wait then I am going to tweak the EPA to see if I cant get this thing flying a lil better. BTW I can actually fly the thing safely and land ok as-is and all of my crash's have been due to some adjustment that I made without knowing what I was doing. My RTF came with NO instructions AT ALL and that’s been my biggest challenge. I think I should just break-down and buy the kk2 board. Really want the NAZA tho

@7439norma 11 лет назад

Frank, have you had any problems with thie esc. I have heard that these esc are bad about burning up. I bought 4 but not sure about them.

@NanobeFLY 11 лет назад

hello again, i have just been flying for second time. My auto level also drifts, have you found a fix for this?

@yeojaerielkaye 11 лет назад

hey frank, this is my setup for my quad d2830 1000kv 2200mah 30a esc how long is my battery run time?

@Boss63cool 10 лет назад

what is the flight time with a 4000mAH 3 cell battery with that setup you have there.

@roadstar499 10 лет назад

Hi Frank...so is this the best board available for this quad? I hear guys have to flash these boards i hope this is not neccessary as i have'nt a clue how to do flashing..thax

@DiehardRCaddicts 11 лет назад

This is actually quite normal as the KK2 board does not have a barometer for altitude hold. You just need to learn to give a little throttle when you move forward to keep your altitude steady and back off the throttle when you flare it to reverse. If you want altitude hold you will need to buy a control board with that option like a Naza M or MultiWii board.

@costas1010 11 лет назад

Did you flash the esc's with SimonK firmware?

@ownbroz 11 лет назад

i have the hobbyking version 3 board, and all the other parts are same, but each time i turn the system on, it just keeps on beeping. beep beep, beep beep, beep beep,,, like that, how do i fix this?

@pstarxxx78 11 лет назад

Seeing that the AUTO LEVEL. Don't work... Do you think the new ORANGE 3 AXIS FLIGHT STABILIZER . would. Work together with the kk2???

@yeojaerielkaye 11 лет назад

thanks, i have order the buzzer with cell checker, i put my timer max 3mins only so i will not damage the battery, the thing is i have 2 sets of 2200mah battery and it limits my flying time, i have to order another sets of batteries to solve my problem. ciao

@anthrmthrfckr 11 лет назад

whats the P and the I means in PI editor?

@vic88my 11 лет назад

did you paint it red ? stock is black color with white ..

@jkflorida 11 лет назад

Do you think a 378 gram lipo is to heavy for this quad?

@Rampage00769 8 лет назад

Help! I cannot get mine to arm? Just started doing this, can't understand why? I have checked and rechecked everything. The receiver is getting signals as the KK2 is reading them in the receiver test menu so I am stumped?

@wheresmichael2194 7 лет назад

in the main menu does it say any errors or "ok". Also are your receivers going the right way? example : If you move your throttle stick up. does it say up? and if its all the way down. does it say down? if they are reversed try turning your kk2 board UPSIDEDOWN.

@iamthaariq 11 лет назад

How long is your flight time with this spec?

@7439norma 11 лет назад

how do i post a video of my sk450 on here?

@DiehardRCaddicts 11 лет назад

Please watch the part 1 and part 2 videos for equipment setup and kk2 board setup and programing.

@DiehardRCaddicts 11 лет назад

I gave up on the auto level feature and haven't used it since making this video. I hear that firmware version 1.5 works much better. You might want to give that at try. I believe you can download it from the kk2 forum on rcgroups. As for me I'm happy flying without it.

@BluSky1 11 лет назад

Rolf Bakke aka KapteinKUK the original creator of the KK board correct the auto level issue in firmware version 1.5 now you could toss it at 75% throttle and it would catch itself. Those who have flown 1.5 say its nearly as crisp as naza auto level .

@dash8brj 10 лет назад

How many grams can this little bugger haul up? :) Coming from helicopters I should have no problems flying it. My camera weighs in around 700g.

@DiehardRCaddicts 10 лет назад

This quad weighs in at about 1300g ready to fly with 4000mAh 3 cell battery. So you are looking at about 2100g-2500g depending on how you mount the camera. Each motor with a 10x3.8 prop at full throttle puts out about 1300g of thrust. It should be able to handle the camera but will shorten your flight times. You might want to go with a lighter camera.

@danieldust312 10 лет назад

You can fix the Auto-Level prob. by updating the firmware to 1.6 . It will work better then.

@ziphozipho7006 7 месяцев назад

Hi I need a remote control please

@j69chevelle 9 лет назад

I've heard a lot of people don't think the auto-level for the KK.2.1 is all that great. Supposedly the KK.2.1.5 with the latest firmware has a better auto-level. I have yet to test mine though. We shall see I guess.

@Stevebroza 9 лет назад

i can confirm that the stock KK2.1.5 FW1.6 auto-level is not great. But they even suggest in the manual that you flash the latest firmware immediately. Flys great with it off though!

@GhostRkkon 10 лет назад

Is it possible to do 3D, rolls and flips?

@DiehardRCaddicts 10 лет назад

Yes, but you would have to turn the stick scaling up to higher rates.

@fluxful 12 лет назад

nice :-)

@7439norma 11 лет назад

I heard that is you flash them that they will work better.

@vikarmsaini3976 4 года назад

Sir my drone is not stable please help me

@DiehardRCaddicts 11 лет назад

Please click on the link to the kk2 forum on rcgroups in the video information bar below the video. the link is all the way at the bottom. If you read through the first couple pages and watch the posted videos you will find answers to the I&P gains and the stick scaling questions you have. It's just too detailed for me to cover it in a comment.

@DiehardRCaddicts 11 лет назад

Never owned that board so really not sure what the problem is. I would suggest searching the rc forums. You should find all your answers there.

@DiehardRCaddicts 11 лет назад

Should have no problems lifting that much weight. At full throttle all four 10 inch props put out a calculated 4000grams of thrust. Even at half throttle would be about 2000grams. This Quad with out a battery weighs in at 900grams.

@skimowhite586 11 лет назад

this is why i bought a naza or at leas something with barmeter and with magnetometer. that way you save your self some money and not have to buy new props and motors because a premature fall

@DiehardRCaddicts 11 лет назад

@minazahmed3858 7 лет назад

i have drifting problem on self level

@wheresmichael2194 7 лет назад

try tweaking the self-leveling settings to your fitting

@GeorgeBonez 11 лет назад

Stick- Scaling is what I am struggling with right now! I have the older “KK1” or “KK original” board with the cheap Radio-Link that nobody seems to know anything about these days! Dont get me wrong ok because I am flying it without crashing it ok. I just wish somebody would help me tame the sticks down! I dont understand the terms P & I and I don’t know what that even means. Ive been asking this question for 2 months and nobody will help me. I just want to slow the stick response down

@DiehardRCaddicts 11 лет назад

About 5-7 minutes with the setup on this quad.

@ziphozipho7006 4 месяца назад

Hi Sir my name is Zipho I need a remote control s 450 please help me

@DiehardRCaddicts 11 лет назад

@notasixpack 11 лет назад

auto level on fw 1.5 is supposed to be much better. Didn't catch what fw you're on.

@loosedog5393 9 лет назад

Barometer for elevation control? Hm. Interesting,!

@wel97459 11 лет назад

Setting both your I and P to 60 was a mistake, the I gain should never be the same or higher then the P gain. And always work with your P gain first and then start adding I, Just the same way it said to do with the rate gains.

@skimowhite586 11 лет назад

it wobbles alot

@thomasmahase 9 лет назад

how high can it go and can i safely mount a gopro on it and how long does the battery last?

@DiehardRCaddicts 9 лет назад

Thomas T you should have no problem lifting a gopro. Here in the U.S. we are limited to 400Ft altitude. Flight time depends on size battery and total flying weight. This setup in the video was getting 7-8 minutes on 2250mAh battery.

@thomasmahase 9 лет назад

DiehardRCaddicts oh cool seems a little on the short side thought but okay and um is there any way i can project my gopros videos onto a display while in flight via tablet/phone if you know?ive seen some gopro video transmitters but idk the range of the use of wifi.
