I've done a complete re-design of my previous fpv quad design (the micro spider quad documented here: http://intofpv.com/t-micro-fpv-spider-qu...e-to-print )



More photos of the build and the 3D printer files and other details can be found here: http://www.thingiverse.com/thing:1594735

It uses the same electronics as the previous quad but is a few grams lighter and is now X-form. Wheelbase is ~105mm, This new version will accept up to 66mm props with a bottom mounted battery. (A 400mAh can be mounted on top if using regular hubsan-size props.) I've also included a file for tabs to glue to your batteries to help keep them in place.

It is designed around the following components:
Micro Scisky 32bit brushed FC from Banggood
8.5x20mm motors from Banggood
600TVL 1/4 Micro CMOS camera from Banggood
FX758-2 5.8G 200mW VTx from Banggood
Pololu 5V step-up regulator (U3V12F5)
Hubsan or Parrot props
4 short #2 servo/wood/sheet-metal screws

Weight of frame: 8.2g
Assembled weight without battery: 42g
AUW w/410 mAh battery: 53g

Awesome build. Do you have pics of your vtx wiring? Planning a micro build myself

Very cool! What's the flight time with the video gear enabled?

Yes, I posted a thread here: http://intofpv.com/t-clean-pololu-step-up-to-fx758-2

Dunno, I always crash before the battery is done   .  (~ 5 minutes with 410mAh.)

Show us how it flies!
I've completed mine a week ago but was disappointed how slow and unresponsive it was.

If you've got a lot of fpv experience, it could well seem slow and unresponsive. (You might want to try some dark edition motors and some Parrot props to pep it up a bit.   )  I am using mine to learn with, and it certainly doesn't seem slow to me! (And I'm just using standard 0820 motors and Hubsan props.)

Also, my flying weight is 53 grams (w/410 mah).  Not sure how it would fly if it was heavier...

BTW, I don't have a DVR yet, so no video (yet). [I think I would be a little embarrassed to show my (lack of) skills yet anyway.] Eventually....

WOW, that is impressive Scotty, Nice work.

nice one. i will do this for sure.

are those grommets enough to keep motors from slipping up and down or there is a need of adjustment from time to time?

The motors are held in only by pressure of the motor holders.  They were designed undersize with the slit that would allow spreading a bit to give a tight fit when released.  I've not had any trouble except in a crash (I've had an arm break without the motor slipping out of the holder).

Edit: I should mention, that this is a little outdated now. There are much better cam/vtx combos available now than then. I'm afraid that would take a complete redesign though.
