190mm Full Carbon Fiber Micro DeX Quad

I finally got the motors: http://www.hobbyking.com/hobbyking/s...idproduct=5433

just to say.... I have not exactly followed which motors are usualy used by others for models of this size....
and I simply chose these ones because they provide enough thrust for GoPro FPV....

they are not quite as I imagined, they are quite long especially if you put x mount and prop savers for 5'' props

because of motor tallness I was not thrilled with the look that has emerged
so that the build was not clean as I thought it would be, I had to drill holes from underneath the hull,
so the motors can be directly connected to the hull with screws.
I plan to put the model into the water and I have to plug those holes.... with X mount that would not be a problem

motor wires are sealed with permanently elastic sealing tape, I'm not sure how to accurately call it but
google said the "Butyl rubber sealing tape" type

I wanted to lower the motors as much as possible, so the X mount "ease of installation" was gone
I also shortened the shafts as far as possible
I have not decided yet what to do with prop savers because they are also a bit too high

But for now the motors are up and the model got its shape

I peeled down ESC's :http://www.hobbyking.com/hobbyking/s...ontroller.html
to get proper cooling and glued them with hot plastic below the ventilation holes

prop savers in original shape are perfect fit to that motors http://www.hobbyking.com/hobbyking/s...idProduct=8237
but I wanted to low the props as low as possible...
So I pierced 3mm hole through the whole prop savers to get shaft rings for motors, so that props can go directly to motors
I put the zip strips to hold props down as on all my models....

and 3 LEDs on back motor : http://www.hobbyking.com/hobbyking/s...RED_1mtr_.html

I hope that tomorrow I will have time to complete the model and finally fly it

Today was the first flight...

essentially micro flies the same as his big brother
I don't see a big difference, except that micro is very jumpy on the sticks and he needs a much smaller stick shift

I will complete build pictures with data details.... and make a video in all conditions

DeX Micro Quad First Flight (1 min 57 sec)

the first day was too windy, quad was more diving than flying
but the second day weather was perfect

DeX Micro Quad and Water (3 min 21 sec)

Perhaps the Hyperion short collet adaptor would work better. I use them on some micro motors but can't tell by the pic whether they would be any shorter or not.
