Yes I will use 6 motors. The heli could be set up as a y4 but then weight distribution, redundency, lifting power, are not as good.

Yeah i would stick with the 6 as well, what is the weight of the copter with everything less motors?

Okay, here is a couple of ideas.
Y6 ... one motor fails ... the remaining motor needs to have enough power to fly the heli, and carry the dead motor too.
For efficiency, ideally the lower motor spins at higher revs / runs a higher pitch and ideally a smaller diameter propeller so as to be out of the tip vortex of the upper propeller. This things could be done in a multitude of ways.....

Cool ta

You any closer to showing more pics or flying? I think you have 69,341.5 people waiting to see this

Have decided on the KDA 20-22L motors, but have not made much progress. Prepared all the motors, and will run the speedies (Turnigy plush 18a ... or actually turnigy sentry 18a as that was all they had in stock when I ordered last), on each side of the arms near the center. I was initially planning on running the wires down the arm tubes, but then it gets in the way of the folding mechanism, and finding space for 6 speedies on the lower deck is a bit awkward, so its like one or the other... tidy or functional. Work has been pretty "full on"

Cool i hear ya

If you get a chance can you take some close ups of the frame\body, i am thinking if there is a way f adding another level inbetween the battery and the floor above that to add the ESC's on their own level or something like that. I personally hate the idea of having the ESC's attached to the arms

The locking mechanism for the 2 front arms is a bolt that slides out of the way of the arm, letting the arm fold. The bolt just clears the end of the arm when "released". With a fair bunch of wires coming out of arm, there would not be enough room to clear. I'm sure this can be overcome, just have to think it out, otherwise resign to not folding the arms. If the arms were fixed, and not folding, this problem would not be a problem.

Excellent job Frank, Nice build, and some very nice flying !!
Maybe you could share some more details about your build, motors, propellers, etc??

Sorry I forgot to post the details.

I used the Motors and ESC from a Feiyu-tech FY-Y6 that I stripped because the frame is to small for me.

3S Lipo 3200mAmp
Motor: 980kv
ESC: 10 Amp
( I know, low in amp but came with the kit and had never a problem with it but when I had to buy them I select a 20-30amp)
I use a APC 10 x 4.7 . Measured 10amp full power on the bench.

Standard kit build and change some stands to fit the Mikrokopter FC and NAV with the GPS on top.
To use standard ESC's I use a AbuseMark I2C to PWM converter which performed very well in the past.

Because of the small ESC and dito BEC I use a Turnigy external BEC to power the beast.

Next I will put some LED's on, two for the Eyes and on red on the tail picker.

I bought also their Cam mount so I will put that one under it (which build quiet nice!) and post a video from and of it.

Hey guys

Will a Helicopter canopy fit over the front of these if so what size do you think?
