Original Post

Recently i designed & built my very own Mini H Quad frame.

The goal was to have a fast and durable mini FPV machine, basically a smaller version of the popular Flip FPV frame.

I wanted to use all high quality gear that i would normally use on a larger quad. This includes a nice CCD camera, a high power transmitter, antenna mount and a built in vibration dampening FPV camera mount.

Enough with the words, here is a photo of the completed project :)

Videos - Mobius Action Camera

















Materials used are Carbon Fiber, 304 Stainless Steel and high quality Nylon 6/6.

The Arms and Legs are 2mm while the plates are 1mm thick.

The frame was designed in Solidworks to use the equipment listed below.

HD Camera: Mobius Action Camera
Video Transmitter: ImmersionRC 600mw Video Transmitter
Antenna: ImmersionRC SpiroNet
Voltage Regulator: Pololu 12V Step-Up Voltage Regulator U3V12F12 - for the 12v camera

1000mah 25/50C
AUW is 321 grams
AUW with 808 #16 Camera is 348 grams
AUW with Mobius Action Camera is 368 grams

1500mah 35/70C

Build Log

These are some of the first screenshots of the first designs.

Then i made a paper version. Here it is next to my Samsung Galaxy S2.

5832c6.jpeg

Working with some forum members and CNC cuts, several changes were made to make it easier to cut and target some problems in advance.

Original leg design

05e739.png
5f6ec1.png

These were revised to make them more flexible so the can be "snapped" onto the frame

3cd6d1.png

Finally i got it cut and the wait started. Finally this Monday past a prototype appeared on my doorstep!

IMG_2918_resize.JPG
IMG_2926_resize.JPG
IMG_2930_resize.JPG
IMG_2932_resize.JPG
IMG_2935_resize.JPG

It might seem heavy, but strength is the goal here. Trust me, everything else is light :)

I stayed up real sanding down the Carbon Fiber edges and assembling. The next morning i got some nice photos.

IMG_2958_resize.JPG
IMG_2961_resize.JPG
IMG_2972_resize.JPG
IMG_2976_resize.JPG
IMG_2981_resize.JPG

Next was assembly. Some of you might has seen my Quadrixette Nano build, i used most of the gear of this.

CC3D test fit

IMG_3002_resize.JPG
IMG_2997_resize.JPG
IMG_2999_resize.JPG


I cut down the Board Camera as shown.

IMG_2885_resize.JPG
IMG_2889_resize.JPG
IMG_2988_resize.JPG

Then i dremeled the edges down

IMG_2991_resize.JPG

Camera mounting hardware includes 4x anti vibration mounts. I swapped the nuts out for Nylock as i dont want any nuts coming off in hard to reach places.

IMG_3006_resize.JPG
IMG_3008_resize.JPG
IMG_3009_resize.JPG
IMG_3016_resize.JPG
IMG_3017_resize.JPG
IMG_3022_resize.JPG
IMG_3025_resize.JPG
IMG_3027_resize.JPG
IMG_3028_resize.JPG

The Camera mount required a little filing of the edges to get it to fit perfect. I have adjusted my design to reflect this.

IMG_3035_resize.JPG
IMG_3040_resize.JPG

The antenna mount consists of a RG316 double shield 5cm right angle panel mount SMA connector. I used a heat gun several times to bend the tail into shape, this is part way through the process.

IMG_3043_resize.JPG
IMG_3045_resize.JPG

2x M5 316 stainless steel washers on either side to distribute force (the only M5 washers i had)

IMG_3048_resize.JPG
IMG_3049_resize.JPG

Antenna attached

IMG_3051_resize.JPG
IMG_3055_resize.JPG
IMG_3056_resize.JPG


Using Liquid Electrical tape i waterproofed my FPV camera, also it's black!

IMG_3059_resize.JPG
IMG_3066_resize.JPG

I put a bit too much on the back, but it will be fine :)

IMG_3080_resize.JPG

What it looks like when dry

IMG_3082_resize.JPG
IMG_3118_resize.JPG

Camera + Camera mount + anti vibration mounting = 17.1grams.... I'm happy with that :D

Motors attached

Receiver under CC3D
Propellers distances

IMG_3091_resize.JPG
IMG_3092_resize.JPG

Next flashing the UBEC 6amp ESCs. What a pain in the ass these little things were. Using the flash tool on 10amp or 12amps was much easier :P

I made a little flashing rig to touch the 4 programming pins using 4 long pin headers bent into shape and a little instamorph to hold it together. Jumper wires run back to the USBASP.

IMG_3096_resize.JPG
IMG_3099_resize.JPG

Stripping 3 of the ESCs positive and negative BEC wires

IMG_3102_resize.JPG
IMG_3104_resize.JPG
IMG_3105_resize.JPG

3.0g is light! but they end up lighter as seen below

IMG_3110_resize.JPG

I didnt like desoldering from the tiny FETs, so i trimmed the wires instead.

IMG_3123_resize.JPG
IMG_3128_resize.JPG

ESC mock

IMG_3137_resize.JPG
IMG_3139_resize.JPG
IMG_3141_resize.JPG

This is the painful part. I routed all of the wires down between the center plates and out the center hole. I made the center hole larger in the next version :)

IMG_3143_resize.JPG

Mocking battery connector wire routing

IMG_3148_resize.JPG
IMG_3152_resize.JPG

Creating the wiring for the video system. Helping hands defiantly help!

IMG_3157_resize.JPG
IMG_3159_resize.JPG

All cleaned up and looking pretty

IMG_3164_resize.JPG

Receiver position mocked again

IMG_3168_resize.JPG

Flip her over, time to start working on the power wiring.

IMG_3169_resize.JPG
IMG_3172_resize.JPG

Now i removed the bottom plate so i could access in between the plates.

IMG_3173_resize.JPG

How i solder each connection together. Keeping the soldering very small and flat to fit in the 2mm gap in between the plates.

IMG_3176_resize.JPG

I never soldered more than 3 wires together at a time, i just kept Y'ing them down til i got down to two wires. Very fiddly but it saves having big clumps of wires.

IMG_3177_resize.JPG

Tape it all up to hold the wiring in place.

IMG_3180_resize.JPG

Top side. In the center hole is the only place the wires cross over each other. The positive goes over while the negative goes under.

IMG_3182_resize.JPG

Bottom again. Getting closer.

IMG_3184_resize.JPG

Soldering in the camera system power harness.

IMG_3186_resize.JPG
IMG_3187_resize.JPG
IMG_3190_resize.JPG
IMG_3193_resize.JPG

I had to cut the inner side of the heat shrink to make the tight radius, a little liquid electrical tape makes sure there wont be any shorts.

IMG_3195_resize.JPG

Almost done! Final battery connector wires

IMG_3196_resize.JPG
IMG_3198_resize.JPG
IMG_3201_resize.JPG

I staggered the wire connections so there were no large clumps of heat shrink

IMG_3202_resize.JPG
IMG_3205_resize.JPG

Top Side

IMG_3206_resize.JPG

Bottom side

IMG_3208_resize.JPG

Put the bottom plate back on - nice and neat!

IMG_3211_resize.JPG

Top side again

IMG_3213_resize.JPG

After a little tidy up with most mocked up in their final positions

IMG_3217_resize.JPG
IMG_3219_resize.JPG
IMG_3223_resize.JPG

Time to attached the ESCs to motors. Dont forget the heatshrink!

IMG_3225_resize.JPG

Positioned for soldering

IMG_3228_resize.JPG

Escs done!

IMG_3232_resize.JPG

Rapstrap to hole them on

IMG_3234_resize.JPG

Battery connector added after mocking lengths

IMG_3236_resize.JPG

How it looks when complete

IMG_3239_resize.JPG
IMG_3241_resize.JPG

Finished! Time to break it!

IMG_3243_resize.JPG
IMG_3244_resize.JPG
IMG_3247_resize.JPG

Next to my Samsung Galaxy S2 for size comparison

IMG_3249_resize.JPG
IMG_3250_resize.JPG

AUW 321 grams

IMG_3251_resize.JPG

To get some HD footage for you guys, i added my 808 #16 v2 Lens D camera to the top, attached with rapstrap.

IMG_3259_resize.JPG

AUW with stock 808 #16 camera 348 grams

Such great feedback :D

Weather looks great today! Maybe a little soggy, but meh!

Currently I'm working on the construction manual. I want it to be very clear and easy to follow with simple assembly drawings (what i would expect when i buy a frame)

I want to prototype another version of the frame, then i will do a production run for those that are interested.

If you have any questions, feel free to reply here or shoot me a PM.
