Stuff it, yesterday I was going to fly rain or no rain, guess what it was raining, still went out. Quad is all conformal coated so I thought lets give it ago. Quad was fine VRX strapped to the top of me goggles wasn't Didn't think to coat that.

You didn't break rules, its just difficult to follow lengthy posts here, better in a proper thread.

Shout box not ideal for discussions!  BMFA affiliated clubs do not HAVE to force achievement tests no more than they HAVE to allow any specific type of model. There are plane only, there are Heli only, etc.

DIY Aerial Cloverleaf / Scew Planar Wheel

Hi just made up some DIY aerials for video tx and rx for FPV use.  For those who have not looked into this yet, you basically get better transmission and reception which is what you need while flying fpv.   For Hardened FPV'ers, yes these types of aerial have been about for ages, so this is a short story of my success at making my own aerial set.

So had a crack at making a Scew Planar wheel(rx) and Cloverleaf (tx) aerial set.

I had some scrapped rf cables from work that had good SMA connectors so that was a bonus.  I then ordered the relavant adaptor to fit the SMA to my HK video tx and rx connectors. Couple of $ from HK.

For the wire framework of the aerial I used 1mm copper core from an off cut of TV coax.  Then I used a link Balders kindly sent me, to work out the lengths of wire I needed:  http://rcexplorer.se/page14/CPantennas/CPantennas.html

Making them was far easier than I expected.  Using croc clips / helping hands to hold the pigtail and a steady hand with the soldering iron was all that was required - appart from cutting / tinning the pigtail and shaping the copper wires of course. 

A quick walk about the house and into the garden with quad video tx in-hand and video rx recording in the  kitchen (selotaped to laptop), gave a good test.  Amazing results and perfect video.  Whereas before with rubber duck aerials, the video reception would break up just going out into the garden with rx indoors (no surprise really, but nice to see my aerials worked) :D  looking forward to trying out the new aerials with LCD goggles for a propper FPV session  ~~

Some pics of my handy work:

Wow they look very good I read some where they are very hard to make, I will check the link you gave later, thanks for sharing the info  ~~

Gav

see how it goes.  apparently mig welder 0.8mm wire works better / get far better range.

Gav

cheers dudes.  Well the video range is good for my needs. i.e. within Range of my futaba tx and local field.  Heres my trials yesterday evening...

Nice video your transmission looks to be solid no interference well done, and that reminds me I should get one of my heli's out I haven't flown one for ages  :rolleyes:

MadMax

Looking good what other equipment are you using

hi Max

I'm using 200mw 5.8gHz video tx and rx, Archos 700 dvr to record the flight, standard fpv camera and GoPro.  Then a pair of cheap 2nd hand LCD home cinema glasses which need to be mounted in some blacked out ski goggles as I am getting a lot of light ingress from the sides making me squint to see during the flight.
Pretty basic stuff and this is how I like it to help keep the costs down. 

Other than that I fly my home built quads with KK controllers and use stock futaba 2.4ghz radio gear.

happy flying!
Gav

MadMax

The Archos is a good idea and they seem to go quite cheap on ebay  ~~

Gav

yeah they catch those cool moments of aerial footage pretty well 'cept the resolution is a bit dire on the Archos 700.  Would like better really.

MadMax

I found this which may also help anyone who wants to make their own  ~~

Just made some new skew planar aerials for both VTX and VRX using 0.6 mig welding wire.  Made 2 pairs and was a nice relaxing couple of hours bending and solderig wire.  Quite satisfying to build.

Copper core aerials have worked fine but these babies should work far better with better range and less drop out or interference.

Just need some decent fat shark dominator goggles now.  Currently using modified lcd specs of ebay which don't quite cut it.
