Have designed a mount for James's "KISS PDB" combined with mini 20A ESC from rctimer.
My plan is to mount most of the electronics between the center plates on the ZMR - only LiPo and Mobius/TopCam on the top

My plan is to use spacers something like in the 3D model I made.

But replace the alu spacers in the front with a simple FPV camera mount.

I`m going to use the mini Sony Super HADD camera (25x25mm)

Does anyone know about a small FPV camera that have the same or better quality as the Sony SUPER HADD CCD 600tvl 25x25mm ?

If I find a smaller camera I may be able to reduce the height to around 20mm

I plan to test it like this (the design where I used 8 "large" 3d printed spacers addad more weight than I wanted.

In this design I plan:
- Power like PDB, ESC, LED.. between the center plates
- Sparky 2 + radio RX between the top plate and the LiPo plate
- FPV camera + FPV tx in the front section (black front alu spacer = 30mm, camera Sony 25x25mm)

I have to design some new arm spacers - 4mm on each side of the arms.

Have done some modifications to the "camera module" (orange in the front)

The module is mounted to the frame using 4 vibration mounts like this:
http://mikrokopter.altigator.com/images ... 0mm_v2.jpg

+ I have made a mount so I can install my 200mW FPV tx
+ A mount for a antenna tube (Sparky 2 antenna)

I plan to do a testprint so I can test if it works the way I want.

Test printed my "Camera module" - I plan to do some modifications and print a v2
Have ordered a micro servo that I plan to use in a V3 to control the FPV cam tilt.

Camera:

FPV TX 5.8Ghzz 200mW:
http://www.getfpv.com/5-8ghz-32ch-a-v-2 ... s5823.html

With this setup I get a "modular". I do only need a 12V wire to power my "Camera module" and the module can be redesigned if I want to teat an other camera or TX module..

To get a more compact "Sparky 2 antenna (433Mhz)" I ordered these:

5cm 433Mhz antenna:
http://www.ebay.co.uk/itm/290803282516? ... EBIDX%3AIT

10 cm "pigtail":
http://www.ebay.co.uk/itm/291053911109? ... EBIDX%3AIT

With this I get a "compact" 4533Mhz antenna setup + great when I later can skip the 2,4Ghz FrSky antenna (when TauLink for my Taranis is ready).

I plan to design a mount for the SMA adapter in the middle of the frame (on one side) to get some distance between the antennas.
Next
