Very funny, sonny.

Thread: Oh cheer, Spring's here, how much flying are you getting in?

Just where do you people live? Here in Bucks it was a horribly freezing day due to the east wind. Put the models in the van, left them there and crawled back into the nice warm shed.

Last Sunday it was great, but only three or four other members appeared. What do the other eighty-odd do?

Thread: Soldering Irons and butain gas
18/03/2012 18:39:51

I got some silver solder, loads of it, on ebay for about a tenner. I think it came from a guy in Milton Keynes. Much easier than (brass) brazing. You also need the flux which Nexus can supply. The above mentioned torches will also do aluminium welding using Techno Weld if you are brave enough.

Hi David,

If you are looking for a gas torch then get one from your local DIY( Wickes, B&Q etc) of the type with a screw on propane/butane can. These are cheap and will braze/silver solder u/c legs etc. Don`t touch the tiny expensive ones.

I solder electronics professionally and although this is a cheapo, can recommend a temperature controlled soldering station which will last you forever @£34.95 from CPC.co.uk. The bits are only £1.09 to boot.

Catalogue No. SD01116.

PS. Try keeping the Tx further from the model at switch on and turn the tranny on for a few seconds before turning on the Rx to allow it to pick up a couple of spare frequencies. Works for me.

Yes, I too have had a JR set loose its bind with the Rx a couple of times but could not even guess at the cause. Each time after a period of non use.

I realise that there are two different tales of woe going on here, Erfolg`s and mine. When I said a `nearby` club it is actually 25 miles away, so local interference can be ruled out.

I do know a little about vhf and shf radio having worked with it for many years, but confess to a lack of understanding of the possible effects of solar activity which some correspondents are clearly familiar with.

I would have thought that once you have `bagged` your pair of frequencies (JR), then nobody else could access them.

By the way, my wireless router kept dropping out at about the same time. It is only 30cm away.

Let`s hope that this weekend is not a repeat.

Thanks for your replies,

Martin

Hi John,

Lets see what other replies there are before we draw conclusions.

If not many, then I shall shut up!

Hi Martyn,

I would tend to disagree with that having flown for many years on 27. A sunspot high noticeably increased glitching for everyone. I omitted to say that an electric glider also inexplicably went in at my site last weekend.

I sincerely hope that this is not the case but have not previously had even the merest twich on 2.4 over the past few years.

Hi all,

There has been a lot of publicity lately about the current high level of sunspot activity affecting various things including radio transmissions. In fact today a newspaper reported that many people were experiencing TV reception problems.

I do not wish to be alarmist, but how does this affect us?

Late last year I had my first scare on 2.4 when a well trusted model suddenly locked out for several seconds. Luckily control was regained, the model landed, and no faults found. Subsequent flights no problem.

I have heard that on Sunday last four models at a relatively nearby club were destroyed due to a similar occurrence, all on 2.4.

Yesterday I took up a 2M funfly for a test flight prior to its sale. On applying down elevator on low throttle setting it blacked out resulting in heavy damage.

No problems have been found with the gear after the crash.

We were used to this in the bad old days of 27mHz but on super reliable 2.4?

Anyone else having problems like this recently?

Thread: Quadcopter

Hi Mike,

Received same board as yours today. Looks like it does indeed come ready for a quad. I googled `connecting KK board` and looked at `KK controller board for quad flyers` and although a bit Chinglese gives you the gist of it. I assume that all esc power connectors are commoned to the flight battery and that the board is powered via the servo outputs but have not had time (or courage) to connect it as yet.

Hi Mike,

No replies on that one as yet. Will let you know if I find out other than on this forum.

Martin

Hi Kal,

That is looking good. May take you up on your offer of help when mine arrives.

Thanks, Martin

Hi Simon,

Loads on there and still ploughing through it. Do not know how the terms P,I and D are set as yet but I expect that these will become clearer once I have received the rest of the bits.

Thanks for that,

Martin

Thanks Chris,

Just the video link which we may be interested in, not the quads (yet).

Hi Tony,

I have been looking at the Heliguy site quite a lot but it is obviously very sales orientated. I shall, however, have a peek at their forum which I don`t think I have accessed as yet.

I am only interested in building from scratch..

There was a link somewhere to three free Vimeos but cannot seem to find them again. These were showing some excellent FPV shots. I do not wish to splash out on this sort of stuff for my hobby but as I am in the (sometimes wireless) video business I could do with finding them again. One was chasing a quad bike, one on a business park and the other flying between trees. May be interested in the equipment used for commercial use but need to show the capabilities to the boss!

Thanks for the info,

Martin

If anyone knows where to find them please let me know.

Hi chaps. Did not intend a pic of someone elses quad but thanks to David for explaining how it may have got there. No offence intended.

Can the HK KK board be used as received or is further programming necessary? Have looked at few websites on this subject but they are rather less than informative. Guess I will have to wait until it arrives.

Martin

08/03/2012 00:06:18

Anyone out there trying to build a quadcopter from scratch? Just started a 450mm one using 12mm alloy tubing and awaiting the KK board, Donkey motors and 12A esc`s from HK. Probably got it all wrong from the start but then I get my kicks from experimenting. You will gather from the above that I am trying to do one as cheaply as possible.

Hi all,
Pics when it is a bit more finished.
Tried to make my own cheapo roll mask using bits of cable, masking tape and UHU POR to get a feathered edge. It worked well but was too labour intensive.
Messing about with my new Hobbyking bead blaster in an attempt to weather it (sandpaper is much more effective) I tried it on the paint colour joins. It gives a slight overspray blend effect but boy does it get rid of all the paint creepage. No need to touch in here and there. Well worth the small cost.
