Well, don't get too smug.  I have seen two cases of radio failure with MULTIPLEX radio in the last couple of weeks. Different sets, different people and different locations.
One locked out and smashed into the ground.  The other one flew away and was last seen heading towards Norway. 
I have every confidence there are many other cases of failures of this brand, but the owners would never dare to make it common knowledge for fear of a knock on the door at midnight followed by being arrested by Multiplex disciples and subsequently publicly burnt at the stake in the morning.  ;)

B.C.
Was the pilot wearing the correct sandals?

Just a note for those who are not aware that Peter Sainsbury of the Bromley Club died last week at the age of 87. He was responsible for organising the Bromley rounds of Kent Interclub events for over 30  years and many I'm sure will know him. No funeral details known other than it will be in Eltham. The photo shows him at the front with timers watching the Ron Finniss Trophy 2014. He'll be missed but not forgotten

Dear South East Flyers

As an occasional visitor to Thurnham where I have met a few of you and know you to be fine, honest and enthusiastic glider flyers might I beg you to consider offering some support at a very prestigious soaring event coming to Kent.

On June 23/24 BARCS are hosting the 2nd F5J Interglide electric soaring competition at Hamilton Airstrip near Ashford. We will have 60 competitors coming from France, Germany, Netherlands and UK including many local pilots. What we need are some willing volunteers to help with timekeeping. It's not an overly onerous task but with 12 pilots per slot, it would be a great help to have some non competitors around to spread the load.

There's no money involved, either way but we can offer a light lunch and and maybe a beer or two at the Saturday evening BBQ plus the chance to witness some of the top pilots in Europe battling it.

If you are interested, please contact me Graham James grjinflightatyahoo.com (replace @) to discuss. See www.interglide.co.uk for more info  :uk:

I've always been amused at the "official" solution to this - putting an additional external electrolytic capacitor across the rails. Whoever believed in that one has clearly never done any sums on the stored charge and the currents involved...

I did see someone recommending using supercapacitors for this on another forum. He did the calculations and used 3 in series to get a suitable voltage and needed around 5F capacitors to store enough charge to cover a low voltage. His system did need an initial connection through a resistor to reduce the charging current to a safe value similar to that used in high voltage ESCs.

Only one system I've tested had the significantly higher dropout voltage though Bob.  They may have improved since then but its too late, the completely unnecessary 5-cell 'solution' is now well established  ;D
With a properly specced (sic) power supply, brownouts shouldnt ever happen in R/C systems  :af
Still feel safer.....lol

As you say, these days it's not "interference!" It's "brown out! "

Yes it was simple then, if it crashed it was the radio, :'' if you piled it in on landing it was a radio glitch, $%& the rest was battery failure,  :study:


I gave up petrol completely with all the glitches in my helicopters on FM radios  :-\

But with 2.4 it all works 'except' turbines, crashes are now blamed on 'static eletrickery'  :D
Never had problems on PCM. As you say, these days it's not "interference!" It's "brown out! "

In the bad old days of 35, it was pretty simple. A new model flyer had a choice of mostly Futaba or JR. Instructions were pretty much the same for all, aerial out of the fuselage etc and do a range check and go flying. Nowadays a degree in computer science is advantageous and there is a bewildering choice of radio gear. Most of which works fine, provided it is installed correctly, thats if you can understand the Chinglese manual. A new flyer does not want to know about protocols and DS whatever. Sometimes I long for the days back of my Challenger 5 when the world was a simpler place! I am now going to go and read the manual for my Aurora in order to understand why my throttle cut is not working....
