Thread: Has Your Club Made Any Decisions Regarding The Coronavirus?
14/03/2020 20:19:56

A previous scare multipled by the media

https://www.theguardian.com/world/2008/jul/21/pandemic.warning

In essence the article says that sooner or later there will be a pandemic and that it might be a bird flu. It will cause massive disruption and kill a lot of people and preparations need to be made.

Quite prescient I would say. Wrong type of virus but otherwise spot on.

The final sentence of the article is salutary: "The most severe flu pandemic was in 1918-1919. It killed an estimated 50 million people around the world."

The media may be having a field day, and at times being very unhelpful but that diminish the seriousness of the situation.

Its much much more dangerous than flu. Lots of people have some immunity to flu and so it doesn't spread anything like as quickly as this is. None of us have any immunity to this, Yes most of us will be OK if we get it, but some will get very sick indeed and if the NHS gets too busy....

We should certainly put in place sensible safeguards to protect members.

1. Stand further apart to chat. At least a metre preferably more. Chat crosswind, not upwind / downwind

2. Don't shake hands and avoid physical contact with other members.

3. Don't go to the field if you have a new cough of fever. Stay at home for seven days.

4. Use sanitizer or wipes containing Benzalkonium Chloride to wipe down and borrowed equipment / buddy boxes etc before and after use

5. Clean your hands when you get back in the car and when you get back to the house.

And don't close the flying field. This is going to take at least a few months to peak and decline. There are other problems that will emerge for those who are isolated for the long term. We (well most of us) are social creatures. Being able to get out to fly safely really could be a life saver over the next few months.

I agree with most of this but BKC (Benzalkonium Chloride) is an antibacterial and not effective against a virus, you need high alcohol concentration, bleach or concentrated surfactants to denature the proteins in a virus (or elevated temperature but I wouldn't recommend boiling your hands).

Yes, you are right. A greater than 70% solution of Isopropyl Alcohol in a small spray combined with a wipe would be more effective.

Thread: Ebay sellers...

Internet go slow = double posting. Sorry.

I buy quite a bit on ebay. In fact a few weeks ago I picked up a high end ARTF built with hacker motor and ESC and Savox servos all round for £150. Its in very good condition and given that the kit alone currently retails for just under £260 in the UK, I was very happy. Yes you have to be careful, but there is clearly great value to be had.

Thread: Unexpected behaviour of SwE in Taranis
06/12/2019 09:16:09

All sounds very odd to me!

I have to confess that initially I thought you were talking about this happening on the Radio. (As opposed to the simulator) In that case, would suspect that your Taranis had been opened and the switch was round the wrong way.

If that is what's happening in the software on your PC, I can only think that there must be something else somewhere in the programming doing that. Is there a throttle cut set elswhere on Switch E?

Thread: Moving the Centre of a Plan when Printing in Poster Format?
19/11/2019 09:46:01

In Adobe Acrobat Viewer...

Select [EDIT] from the top menu

Select [Take a Snapshot]

Select the area of the drawing you would like to print with the mouse

Select Print or via keyboard [Control P]

And then obviously make sure its printing at 100% in poster mode.

And Bob's your uncle..... Very handy for selecting small bits of the drawing to print on single bits of paper for templates etc. Also you will find that that you can get away with only printing parts of the plan.

Having just watched the NATS training video....

A shame that the figure is shown 'checking his drone' by holding it with his hand and arm inside the arc of the props!

Thread: Latex paint anyone?
21/10/2019 18:18:39

p1020034.jpgYes, you guessed correctly. It's household emulsion. You can spray it mixed with premixed screen wash. Once its dy its not a bad idea to add a protective coat of varnish. It works surprsingly well, although I would advise using decent quality emulsion. I've had good results using Crown emulsion tester pots mixed in the local Crown centre. I would probably use Astonish floor polish now, [Great stuff - basically thin acrylic varnish and only £2 or a big bottle.]

Model above sprayed with the Crown stuff.

My Experience with Turnigy Lipos from HK has been very good. Also the Zippy ones.

I for one would be iterested to hear more, and see pictures. I presume you mean that you can buy extra pieces which allow for the length of the cut to be increased?

Thread: Servo Torque guide - Sport Flying (electric)

How many amps was the SBEC? And how many servos was it driving?

Thread: Aliphatic glue
17/04/2019 18:52:57

Quick answer no! It won't really adhere properly.

Your glues for Depron are.... Epoxy, Polyeurethane, [Gorilla Glue] UHU Por, foam safe CA and RC canopy glue [Zap Formula 560]

The Zap Formula 560 is a bit like PVA, but sticks much more effectively to foam and dries clear.

Depends what you are building really but UHU Por and Gorilla PU glue will allow you to do most things.

Thread: New Drone/Aerodrome Regulations - Is your club at risk?
13/03/2019 15:20:40

I should clarify.

I'm not a committee member, but I know that the commitee have put in a lot of work. I know that they have approached the ATC with a draft memorandum based on the BMFA template, but as of today have not been able to resolve the issue.

I wrote to the UAS sector lead and UAS Policy (Operations) individuals at the CAA as a private individual, expressing my frustration that as a club instructor who has taught people to operate models safely and legally, the new rules have stopped me enjoying my hobby but will do hardly anything to prevent those who are prepared to operate illegally.

13/03/2019 14:35:36

My club is shut down at present and the gate locked awaiting outcome of discussions with ATC at the local Airfield.

I find the whole thing very frustrating. As a law abiding model flyer I can't fly, but the rules will do little to prevent those who are prepared to break the law.

I have politely corresponded with those responsible for UAS policy at the CAA, and they did do me the courtesy of replying and assuring me that they sympathise and that they "recognise that aero modellers are a conscientious and law-abiding group" but couldn't offer any help in dealing with the local ATC.

I was amused to see one forum member's insistence in the thread about the 737 MAX issues that the CAA would not take a decision lightly.

They have just banned the flying of 25 gram chuck gliders in every open space within 2.5 miles of a protected aerodrome without ATC permission and with very little warning. I do wonder whether kicking a ball in the park might technically be prohibited under the rules.

I'm wondering what would happen if I ring ATC and ask for permission to fly my chuck glider!

Now working for me. No need to clear cache.

Thread: My motor has started screaming
26/09/2018 14:41:04

Screeching and kicking on startup is often a sign of a failing solder joint on one of the connectors between the motor and the ESC as Chris says. Worth checking.

Thread: BMFA Website down...?
26/09/2018 14:32:04

I’m in France usinging Livebox wifi in a gite. I’m getting “Safari cannot open the page because it could not establish a secure connection with the server.”

If I use the WiFi on my Android phone in chrome I get: “This site can’t provide a secure connection bmfa.org sent an invalid response. ERR_SSL_PROTOCOL_ERROR”

If I turn off WiFi on the phone... although it was working it now says that bmfa is taking too long to load..... and as soon as I posted it loaded properly!

Hope that is helpful

Thread: Design & Build FW 200 Condor / Syndicato
23/07/2018 20:18:27

Magnificent build.

Taking a quick look at the motor, and particular the reviews that have been added for the motor it looks to me as though some users have discovered that the prop information given in the specifications is incorrect. The review that is currently first in the list indicates that the motor is being used with 11 inch props and a little further down the reviews you find this comment:

“Great motor for a slow stick (original). HK has the wrong prop specs: at 11.1 volts, a 3S LIPO, the normal prop to use ranges from a 11 X 6 (12 amp draw) up to a 12 X 6 (15 amp draw).”

I think that may be your problem. You either need bigger props (is there ground clearance?) or more volts (as you suggest) or even possibly to consider swapping the motors for higher KV units.
