Y6 Builders thread

Turned a CS 6 into a Y6 and having the yaw issues you describe. I'm ready to try smaller props on the bottom, but I'm wondering about the configuration to make it work. Are all Y6's counter clockwise top and clockwise bottom?

No MK are different.. what FC are you using on your CS?

Where do you guys buy these Y6 frames? every Store i lookup that sells droidworx frames they dont have a coax y6 frame :p

As they aint as popular as other frames I guess. Normally they can be sourced in a few days.. where on the planet are you

i bought a regular DW hexa and just built it as a Y6 using the parts it cames with, which left me with spare booms.

the coax motor mounts are nothing special/different to the regular motor mounts - i confirmed this with DW before buying.

don't know about expensive controllers, my AQ50D has cw on top and CCW on bottom, so does Rabbit controller, but i haven't tried that board in y6 conf yet. If i remember correctly, MK uses a mixed setup, with rear motors opposite compared to front motors.
You should try increasing pitch on lower motors because lower props are receiving faster air.

Aye Up.. everyone posting in here it would be great if you could post your complete set up so everyone knows what frames, motors, props, esc's frames and tx's you are using

Here is my Y6.
View attachment 3991View attachment 3992

Frame is a Rusty UAP-1,18 AMP esc,4s 4000mah Tipple batterys,Graupner E-Prop 11x5,Copter control,TorxPower MC2216 Pro,DX6i

Weighs 1.63kg, 2.12kg with 1x 4s battery(maybe a bit more since I last weighed)


PS the bear is not normally attached ,he came to stay with us as the "take home bear" for a few days,the girls decided to send him on a mission:)

Getting about 11 mins(ex bear).

Aye Up Jake.. Maybe I should nick your Aye Up sign for my aviator.. Love the teddy thing.. thanks for posting your set up

I'm using a naza controller so it doesn't have an option for mixed prop directions. Maytec esc's. I will try higher pitched props on the bottom.I just used the parts for the CS 6 and built it as a Y6. Saved about 6-8oz if I remember right. And I could build a second one for a minimal cost. It's so much easier to move around.

Just tried 11x4.7 apc on top and 10x5 graupners on bottom. Seemed significantly better, but there wasn't much wind. And I liked the sound. :)

Here is my personal Y6 fpv machine :) Droidworx Y6 Frame , Wookong M , Torxower Motors, T-Motor 30a Escs, OSD , Iftron 5.8ghz fpv tx , Graupner 11x5 top and bottom , Now flying on Maxamps 11000mah 4s and get around 20 mins with gopro and fpv pixim camera etc . This is my favourite fpv platform .

Hi Geoff. I see your using 11,5 props on this. what is your experience with it? we are running 13,6.5 & i was considering testing some smaller props. have you picked up anything larger than the go pro setup with those props & if so how did it fly? Just think we might be spinning abit too much lift.

A question I would like an answer to ..
For an MK Y6 the mixer table the [Gas] values for the lower motors are 76 while those for the upper motors are 64. According to the MK wiki, 64 represents 100% so 76 would be be 119%. I assume ( as one always does with anything MK ) that this would cause the lower motors to always run faster than the upper ones. There have been posts where people talk about fitting differing sizes of props to lower and upper motors, are they just compensating for , or adding to, the pre-existing differential or could it all be done in the mixer ?
Just for comparison, what equivalent values are used for DJI mixer tables ?

Im running the 11x5 props with this set up only because I reduced the length of the arms to suit my flying for FPV , I did originally fly with full size booms and 13 " props and it was very stable but with the smaller sized frame and smaller props it was extremely responsive .
Even in its current set up it will lift 10,000 mah lipos with ease and still has ooodles of power to spare with the gopro etc , but Dave is the man to ask about 13" prop set up as his is running that size and I think he is loving it.

You are wright there Andy, there has been posts about differing props, but no one takes me serious mybe my face don't fit,
I think most of the thinking and the manual states that you use same size top and bottom. It will have about 15% less efficiency than all in the same plane. However, several have tested and use now, larger on the bottom. (thanks RCMan for all the testing) On somebodys X8, he has 11X4.7 P on the top and 13X6.5 thin electric on the bottoms. The thinking is that the air on the bottom prop is disturbed so you need a bigger prop and more pitch to get the same thrust. And the X8 flies great! Same goes for the Y6

Now then now then.. I think I am about the longest flier of the Y6 on the forum.. I have tested more configs than I care to think about.. The MK as far as I know has the mixer set to avoid the use of different props... Dont know about the DJI WKM coz you cannot see the mixer table its just a choice to make when setting up the config. I have used 10x5 and 11x5 Graupners on my standard DW ADX3 but right now I have changed my setup and am getting different results.. Its a long road to get your individual config sorted hence why I aint posted my total con fig yet.. trial and error.. I think the bascis are there but to say THIS IS THE config for any craft is dangerous. Its down to the individual to decide what is right for them and not fly a craft that is based on someone else's preferences.. EVERTHING makes a difference. even the batch number of the ESC's used to the motor type.. It aint that simple to post... THIS IS THE SETUP.

Not sure what this means.. everyone on here is a beta tester and everyones opinions count. We all live and learn from each other..

What I am trying to find out is if the Y6 mixer table was calculated such that the different efficiencies of identical upper and lower props was taken care of and that anyone using differently sized props is only tweaking something that is there already. The MK mixer tables are not sourced from MK, they seem to have spontaneously created themselves, no one seems to know who actually wrote them or how. I would like to compare DJI's values with the unofficial MK ones to see if they differ, perhaps someone can let me know the DJI values.
In the mean time we'll try 12x6.5 on top and 13x6 on the bottom to see what happens. Might even try altering the mixer values in the spirit of exploration.

Andy.. When I complained to MK about BL temps they told me 13x6.5 props were to big for my HL ADX3. That was when I had loads of problems with brand new kit from them.. brand new kit that bits fell off! I stuck with MK and totally rebuilt my distro with coolers and triple nay checked a miillion times over then checked everything again.. Still had Hi temps and BL shut downs.. loaded the latest firm ware and guess what... BL's back to normal.. 50/60ºc with the original and very expensive 13x6.5 carbon xeors... BUT still could not get the bloody thing to track the altitude I could with my little ADX3 / WKM.. this to me is vital for the filming I want to do.. How Lec filmed the shots he did of the MTB track was bloody brilliant considering he is flying MK.. Maybe you just got a great FC build... Like Bart.. he swears by his.. I now swear by my WKM as it wipes the floor for what I want to do over the MK FC/BL/nav/gps combo..

As for the mixers, well like everything MK its all just smoke and mirrors to me.. My original RTF came programmed with the mixer I sent you.. I have seen various ones on the web but I saw no point in mucking around with um when mine flew fine.. well I thought it flew fine until I went to 'THE DARKSIDE' as you put it...

I think maybe we should have another meet and see how lec can fly my ADX3's..

It may be quite scary!

Dave ...
Yep, every Y6 or multirotor is going to be an individual, chaos theory rules.... too many variables. Actually it would be interesting to know how consistent Parrot Drones are since they are mass produced on a production line rather than built by individuals.
In the full scale aviation world, before fly by wire came along, every aircraft was an individual and a pilot had to be able to adapt accordingly. Despite gyros, accelerometers, gps and such, multi rotors are still in that world. Modern aircraft flying by wire present a consistent interface to the pilot who can confidently fly an airliner from 100 seats with 2 engines to 400 seats with 4 engines for as long as the airframe manufacturer is the same, the engines, however, can come from any of 3 manufacturers. I look forward to the same happening in our world but I don't expect that any time soon.
