Hi All. I have just received a beautiful plan, (2 large sheets), from Derick Scott of Model-Plans, see above, of the CAP Devils Duster. The plans are a perfect copy of the original aircraft designed by W. Fleming, cleaned up with no yellowing, well done Derick. Placing my part built wings over the DD plan, the shape is almost a perfect fit, (got that right), and the wing section is almost the same, mine is an NACA0015. That is about the only thing in common that my design has with the original, mine will be slightly larger and in 3 sections, laying the original plans on the floor it would be very difficult to get it into my car. but not impossible. If mine flies like the original did, I will have no complaints. Happy landings David

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 David

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 David

2012 Vintage Mass Build - What are you building?
DCW replied to Steve W-O's topic in The 2012 Vintage Mass Build
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. David -
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 David

Thanks John for that tip, I have just emailed them. David

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. David

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 David

All very useful info. Incidentally if anyone has built an interesting delta, we would all love to see it. Thanks Guys. David

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). David

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 David

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. David

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. David

Hi 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 David
