Thread: Return of the SMA

Thank you David.

I think this will be as formalised as it gets, it was always known for its non members.

maybe after the fly in things might change.

Here's an April '91 Radio Modeller review by Dereck Woodward of the Mini Flying Machine, copied from FMK's Facebook page.

Mini Flying Machine - Kit review

I bought one of the original kits at the Nats swapmeet last year. reduced to £10, nobody wanted it. Will have to get it built.

Back to the meeting - It will probably be on a Friday, will look at a suitable date soon. Any suggestions welcome.

If you need any inspiration for models the plans service has many designs. If you want a kit FMK are very good

https://fmk-models.com/radio-control-model-aircraft-kits-2-c.asp

and Greyfish on ebay does some ready build ready to cover models at a good price

22/09/2020 16:26:25

Thanks for the link, I couldn't find anything on the web. I remember Gray was a big enthusiast along with Dereck Woodward.

 

It looks like 2cc or .12cu is a sensible limit. It is small model association  after all. If anyone wants to organise a medium model size day then go ahead

It did have rules on engine size, although looking at some old photos it could have been .12 ci for r/c. A few models have OS10 and SC12s in them. No other rules though.

Those of you who flew in the eighties might remember the SMA and its non members. The SMA events at Old Warden were a great success with lots of fun with the small and inexpensive models.

I have been approached regularly by modellers who would like to have another get together on the same lines. It will probably be late spring next year at Buckminster in the week. (covid permitting) Guidelines will be similar to before:

Radio and free flight - 049 glow and 1.5cc max diesels. Electric 100 watt max

Control line - 09 glows and 2.5cc diesel max

I would appreciate it if you could post if interested. If enough support I will organise it.

None of those. A return to smaller engines please

Jon has already stated with his reasons why this is a non starter I'm afraid.

Must have missed that what did he say? I realise that economically they would cost as much as a larger engine but I would pay that for a 30 or 40 size Lazer

On the subject of oily and smelly diesel exhaust residues..............is there any reason why synthetic oil cannot replace the castor that all commercial diesel fuels seem to contain - and how about using a much more refined and cleaner burning lamp oil in the fuel that's advertised as a replacement for use in smelly old green house heaters running on paraffin?

A fundamental engineering reason for sticking with the old familiar brew, or is it just a case of "we've always done it that way"?

Edited By Cuban8 on 06/07/2020 13:25:27

Most 'synthetic' oils are not really synthetic, in way of being an 'artificial' lubricant. They are still made from crude oil, which comes out of the ground. But the crude oil, rather than being broken down to the required 'thinness' is broken down fully and then rebuilt, equals 'synthesised'..

As a result they don't mix well in the high ratios needed with the other constituents of diesel fuel. Which is why such fuels, if they use any at all, only use a small proportion, the rest being vegetable oil.

This is not true. Automotive turbo diesel fully synthetic mixes perfectly at 15% with white spirit and ether

Thread: Diesel anybody?

I have used mineral oils, synthetic oils, and also white spirit. Fortunately with all these variations the diesel perfume lingers for days in the car to remind you of the flying session you had.

Unfortunately only the rich can afford to get justice in this country, but good luck and I hope your son makes a speedy and full recovery.

When it was quiet at work I used to try and find topics that Percy hadn’t posted on. It used to pass a lot of time, he had an opinion on everything.

Using duraglo I have no coking or varnish build up. The internals are always clean and I get very long engine life. In my fourstrokes I use model technical special 4 stroke with even more castor and again no coking or varnish. I'll stick with what works for me thanks.

I am not averse to trying new lubrication ideas. My ED by West runs happily on turbo diesel synthetic as recommended by Weston, and my Laser 80 diesel is happy on sae 50 mineral oil

16/03/2020 12:28:49

I have run castor, synthetic, and castor/synthetic mix in model engines and racing two stroke motorcycles. The only cases I had of lubrication failure or damage was when I used solely synthetic oil. I think they both have there own advantages and disadvantages. This is why I settled on duraglo  and have used it for years without any problems, as have many others. What gives you the right to try and get it discontinued?

I have a 60" stick with a Super Tigre 51 in the nose with a 12x6 prop. Ample power for any acrobatics, not unlimited vertical but more than enough for sport flying. So 60 inch span is my recommendation.

I am the very lucky chap that Pete built the Mule for. It is still in regular use, currently in a Sharkface and gives me a huge smile every time I fly it. Thanks Pete.

There was enough advance notices and warnings not to arrive before 5.30 so no complaints there. I arrived at seven, got near where I wanted to be and set up by eight. Perfect. My only moan would be the miserable toilet/shower attendant continually complaining about wet floors but not stopping up the loo roll and paper towels.

Still, one of the best nats ever
