A corkscrew type anchor (get them in pet shops for a dog) is much safer.

point taken, Ralph.

btw, it takes two strong hands to extract it from the ground.
also 'anchor' sold  here does not look any safer.

. I don’t see a securing peg anywhere in the picture, assume you do have one? :?:

"securing peg" ? do you mean the "anchor" ?
here is my "setup"

 that bungee looks in very good order.

That picture is from the shop. Mine is one year old, the rubber piece is not exactly of high grade.

Misceleanous / dead cell in a 4-cell pack

just got it charged - looks like a 3-cell pack with 0.5v lower voltage

Misceleanous / dead cell in a 4-cell pack

« on: May 20, 2010, 21:46:01 PM »

Hello there,

I just discovered that  my 1 year/2 flights old 4-cell Rhino Zippy 2350
got a dead cell
The cell #3 is completely flat, in fact it has about 0.4v negative(!) voltage.
The pack was absolutely fine November last, when I had it fully charged.
It was sitting in a box for the winter.

Trying now to charge it using balancing charger -the charger just ignores #3 .
I wonder if there is any future for this pack apart from going to the salty bath ?

1.2GHz/500mW  

page 29, table 13
http://www.comreg.ie/_fileupload/publications/odtr0271R1.pdf

Video Senders at 1349MHz up to 500mW - perfectly legal here,
if only you can find who makes them

still, you will have to obtain the license to use that
and it will be restricted to use only within a particular area
(if any local farmer already got such license in area where you live - you will not get it).

the info above is from comreg, I had a chat with them couple years ago.

FPV / FPV in IRL

« on: April 26, 2010, 11:52:59 AM »

Surely that would depend on the amount of separation of the video and rc signals and of the rc receivers image rejection ability..............wouldn't it? :?:

Keith, I am not educated enough in RF area , so I can only quote lads from rcgroups - "the safe way is to use 35/72MHz radio with  whateverGHz video link".

One working FASST futaba transmitter will successfully block any video on this band.

please explain :?

no, it would not - potentially, you may miss couple lines of video.
also his last statement is correct - you can't use both radio and video at 2.4GHz - rc receiver will be "flooded" by a transmission of nearby video TX .

our neighbors in UK managed to get this activity organized and *insured*
http://www.bfpvmfa.org/
http://www.firstpersonview.co.uk/myfiles/file/FPVsafety.pdf

the main points are:
- EU law only allows max 10mW airborne video tx
- you have to maintain visual contact with your model
(for reference, at 600m distance 2m model will look like a dot)

FPV is not banned here - you just have to stay within the limits
and (if anything happened) be prepared to pay the damages  as you will not be covered by MACI insurance.

here is my BD-5
built according to plans from rcgroups


have not flown yet.

unfortunately, the vector of thrust is pointing bit ahead of CoG
so any attempt to get airborne from the ground makes her digging the grass

How can I get information about Tx restrictions ?
I now that people (around the world) use 900MHz/1W , 1.2GHz/500mW  or 5.8GHz/500mW for video links.

only 2.4GHz 10mW TX will be legal in Ireland,
you can use 2.4/500 if you have HAM license.
you can verify that with comreg.ie

also, you will NOT be covered by MACI insurance for this purpose.
