KKMulticopter.kr - Minsoo Kim Build Thread

Just started mocking up my new quad (or hex :) or maybe Y6 ) using parts just shipped from Korea from www.kkmulticopter.kr

The center plate design is nice, includes slots for velcro for the battery and 8 arm locations to enable you to build as a tri/y6 quad or hex config, power distribution board is very nice as well, gets rid of the mess.

Mine will be topped of with a small plastic container holding the "Minsoo Kim blue board" and my FrSky reciever

Power will be 3S 2650 battery to start with.
Will post some proper build photos later, for now are the "mock up" shots

Well, finally built it, and , very boring to most, it is a quad.
Built a quad as I have a customer after a small camera ship, and a quad was the easiest platform to setup that fit the bill.

Did things a bit different, controller is mounted under the frame, with a flat platform on top (mocked up using corroflute, finished article will be polycarbonate cut on a water jet)

The flat platform allows the battery to be central with no camera, and when the camera is mounted up front (forward enough so the props are out of the picture) the battery(s) are moved back to counter ballance. test flew like that in the lounge (not sure what american is for lounge, sitting room maybe ?) , and it worked fine

The camera used is just a cheapy, but is the same weight (200 grams) as the customers go-pro

Weight with just battery is 1000 grams, did a test flight today (platform removed) and carried a 1450 gram load (51 oz) , flew very well, could certainly tell she had more inertia, but stable and flyable, throttle to hover was 60-65% on 4S

well, after proving she can carry close to 1 1/2 times her weight, time for a re-configure , I still have a soft spot for tricopters, but enjoy the close in hovering characteristics of a quad - so..........compromise !

I present - the Y4........with wheels :)

Its a std kkmulticopter.kr / www.kiwirc.com reconfigured in a Y shape, and the controller re-programed.

Added the wheels as had no other landing gear that was long enough to clear the bottom mounted motor, and am happy i did now :D

give it less than hover throttle, then push forward on the stick to get the rear wheels up, and drive it around like a wheelbarrow on the ground.

Will try to get some vid of it on wednesday

Looks bloody great.. nice one.. I am thinking of building a fun quad / Y6 just as through about.. How easy is the Fc you are using to set up?

Hi Dave,

The "Blue Boad" from Minso Kim is super simple to set up, theres a programming menu (all done by moving sticks on your transmitter) and 3 pots to controll the gain on Yaw/Pitch/Roll - I have found that the Y4 requires more gain than the quad, makes sense as it has less power available for each action.

These frames are an easy build, its over too soon, if you know what I mean :)
like a mecanno set, and easily reconfigured (the centres support 3/4/6 arms)

Cheers

Just ordered the quad kit from MK,hopefully it`ll arrive next week.
I`ll look out for you up Fleetwood Rd way,I think i`ve seen a VW van on your videos ,so i should be able to spot you if your droid is on the ground.

Just maidened mine,first time I flew anything and it stayed airborne for more than 5 seconds.Ended up with one flight to many in the fading light,and hit the dirt a bit hard.Just spent the last half hour straightening two bent props,not 100% true,but they`ll have to do till I can get replacements.
