Thread: Model Shops
23/08/2016 20:43:34

Hi all.

I have just visited Gliders Distribution, that is the virtual tour of the shop on their 'landing' page. Must have spent half an hour looking around the shop at kits and in particular materials etc. I only wish I had a shop like that near me. Take a tour, thoroughly recommended.

Happy landings

Thread: Devil's Duster

John

Thanks John I'll go to it straight away. I had all but given up on obtaining a plan for the DD, so I drew one up myself from memory. As the drawing progressed however, it has moved away from the original in that the DD was a 56inch triangle and would difficult to get in and out of a small vehicle, (back then I had a Volvo estate). I have designed it to be in three sections, i e Port and starboard wings and a centre section. I hope I have got it right, the DD plan will soon let me know.

Thanks again

Thread: 2012 Vintage Mass Build - What are you building?
17/07/2016 13:17:00

CAP Devils Duster.

I had the above delta in the mid eighties, now long gone. I decided to build another but have been unable to track down a plan. I am therefore resigned to draw up a plan and build one from memory... Hope I get it right!

See 'Devils Duster' in the forum.

Hi John.

I've managed to contact Anglia Model Centre about CAP kits. They have most of the CAP plans, including the Vulcan, but not the Devil's Duster. Back to the drawing board I guess.

Thanks

To KiwiKid.

Like your delta, very much. Also reminds me of a Handley Page HP115, another favorite aircraft. Pusher design that's started me thinking.

Hi Piers.

Go for it...

I have reigned myself to design and build a super DD. In this case power would come from an ASP 80 fourstroke?

Some years ago I converted one of my wings to electric. This was the Pterasoarus based on a Manx Monarch but made to look like a vintage scale aircraft, fooled a few lads. It was originally powered my a vintage OS 60 with open 'rockers', down on power compared with a modern four stroke but still good.

Electric conversion consisted of: EMAX GT3526/04, EMAX 80A ESC, and a 4 cell, (14.8v) LiPo

This was down on power even compared with a Vintage OS 60. It just takes longer to get off the ground, it is after all a powered glider! I probably should have used a more powerful motor with a 5 Cell, but this would, of course, increase both weight and cost.

Perhaps a smaller DD with a 3 cell would be a good idea?

After a bit of research last night, I think the closest match for the original wing section could have been an NACA 0010. I think that that is the wing section used on an Avro Vulcan, that's good enough for me. 10 ribs per wing, but maybe the last 2 or three ribs should be NACA 0008. Also slightly larger elevons to increase the rate of roll and a better power to weight ratio to give a more vertical climb. Hope we don't spoil it.

Pterasoarus with OS 60, I will upload a 'pic' of the aircraft in it's present guise when I next get to the flying field, whenever that is......

Bye

All very useful info.

Incidentally if anyone has built an interesting delta, we would all love to see it.

Thanks Guys.

Hi Piers.

Thanks for joining the thread.

Yes. I believe it was a Symmetrical wing section, Possibly a NACA 0015? If I cannot track down a plan I guess that I will have to design and build my own version, but it would be very frustrating after spending hours drawing up and building only to find that my design doesn't quite fly the same or perhaps I am just being lazy?

As to the CofG, originally it was well forward and on the first few flights elevator control was poor and the elevons had to have plenty of 'up' trim. It also it flew fast and was not particularly pleasant to fly. I then put ballast aft which brought the CofG into a much better position and never looked back.

I think that the elevons provided the reflex, mine could be trimmed to fly 'hands off'' when inverted.

I hope that the action man on Bob Fletcher's version had a parachute. I think a parachuting action man was part of the show. Might just try that myself!

The size looks about right, (56 inch span).

Thanks John.

That is one of the 'coolest' pics I have yet seen on the forum. Is that you holding back the Duster, there seems to be quite an audience in the background. I find deltas and flying wings quite fascinating and the DD was very much a favorite of mine. That's why I am looking to build another, assuming the plans are still available.

Thanks again

Hi Percy.

Yes you are quite right, they were spectacular both to fly and to watch. I believe that mine was one of a trio flown at model shows in formation. The story goes that one 'pealed off' out of control and one of the pilots said 'your aircraft is gone out of control, Oops it's mine'. Whether there is any truth in that story, who knows...

Mine was initially powered by an Irvine 61, later an OS 61. Today I guess I would use a 61 or 70 four stroke to try to keep the noise down, with a tuned pipe it could be heard a mile or so away. The only problem was from 'ground effect' when landing on tarmac. It would float on it's cushion of air long after the elevons had become ineffective. To cure this I would take of on the runway and land on the grass. Being heavily involved with flying wings this is a common problem I have found when landing on a hard surface.

Thanks guys, your comments and advice are very much appreciated. I will continue my search will all of your recommendations. If anyone has built a similar machine I would love to see it.

Keep flying, regards.

complete a pac.jpgdevils duster profile.jpgHi all.

Some years ago we had an excellent 'one stop' model shop in the Wiltshire town of Warminster. It was called Hobbies and it was run by a well known and distinguished modeller, no name dropping.. he may well read this. Hung up in the ceiling was a CAP Devils Duster, it had been there for some time with no takers. I took pity on it, made on offer for it which was duly accepted.

After dusting it off, I fitted new radio gear and an 60 2/stroke. To my amazement it handled and responded beautifully, neutrally stable but still easy to fly. Under power I could fly it at very high angles of attack without stalling and in a light wind landing was almost walking speed. Loops slow rolls etc. could be performed with ease.

Stupid like, I sold it, together with the plan a few years ago. Has anyone else had experience with this 'beast' ? Better still does anyone know where a plan could be obtained?

Happy landings

Thread: If your partner was an aeroplane 2
28/08/2015 21:32:02

smileyThis is one of the best threads yet! Let's hope the ladies don't see it...

My wife would be a Brequet 905 Fauvette. I was fortunate enough to have a half share in a 1/1 size version. With it's dolphin shaped fuselage, tapering wings, elegant 'V' tail and original color scheme, it just seemed to solicit for attention.

The first time I flew it with it's sensitive controls, it scared the pants of me and at first I didn't go very far with it, but once I got to know it there was no holding me back. I didn't want to fly anything else...

Thread: Drone Near Miss.
27/07/2015 18:02:24

Copied from my thread of 9th July....

I don’t like to use the word ‘drone’ I prefer UAV or Multi-rotor, but it looks like we are stuck with it. So I will follow everyone else and call them drones. The first 'drone ' I ever saw was in 1961, the XT581 used by the British Army, check it out. I quite like these machines, or for that matter any form of model flying. My concern is however, that these aircraft are not just being sold by our favourite model shops, with all of the help, advice and safety recommendations that usually follow. That is...

Why not join a club and get help learning to fly your new machine.

Get yourself insured by joining an organisation BMFA, LMA, BARCS etc.

Don’t fly in built-up areas or on private land without permission. And so on.

Maybe these RC aircraft are being sold by the wrong people, to the wrong people. My first reaction is ‘not my problem’, on second thoughts though, well, maybe it is. Particularly if local authorities start to bring in restrictions or maybe refuse planning permission for new clubs etc. We are after all ‘Judged by our worst’. I wonder just how many of these non-model shops are responsible enough to give the above advice. How about a few of us becoming ‘secret shoppers’ and reporting the results back to this thread? Any ideas? DW

Thread: Ideas for new polls
09/01/2015 19:38:29

Hi All.

Why not have a follow-up on the latest poll, (i. c. or electric).

That is, for models 7lb. and over. I have found that when I electrify this type of model both costs and weight escalate, not to mention the shorter duration. Below that weight, unless you require constant full power, it does not seem to be so much of a problem.

Thread: July 2012 issue feedback
05/06/2012 16:57:37

Browsing the pages of the July 12 issue of RCME I read the ‘Top letter’ and was very disappointed that such a letter would even be included in the magazine let alone be given the title of Top Letter. I do not believe that this have happened to RCM&E a few years ago.

Not long ago to buy a ready made model you would have had your ‘leg pulled’ something rotten, (in the nicest possible way) and been called a ‘cheque book modeller’. We have all at some time or another purchased a model built by someone else, I even produced a limited run part built kit myself to get people started, but ARTF aircraft were purchased ‘as well as’ and not ‘instead of’. In one club that I belonged to a Falcon Sunbeam trainer was re-sold at least four times before meeting it’s demise.

Unfortunately, in recent years many model flying magazines, not so much RCME, look more like the pages of a ‘Toys R us’ catalogue.

Fortunately July RCME redeemed itself by Alex Whittaker’s article ‘Behind the wire’. The models were nothing short of stunning. Also ‘Crossing the divide’ with a ¼ scale reconnaissance Spitfire, scary but brilliant. I have yet to study AW’s article. I have read ‘snippets’ of it and liked the end bit ‘No change’, the truth sometimes hurts!

With respect to ARTF models, it may not be a bad idea to look at Model Flying’s own polls:

Q: Are you presently or will you soon be building a traditional kit or plan model?

Q: How many ultra micro models do you own?

Q: Are you a trad' balsa man or have you embraced the foamie revolution, what % of your fleet are foam models?

Are ARTFs a good thing or a bad thing? A new poll maybe?
