North Worcestershire Model Aircraft Society Club Newsletter Rushbrook March 2013 March 2013 Events Sunday 7th April 2013 First BBQ of 2013 Season and examination day at Tardebigge. There will be an opportunity for members to be evaluated for their ‘A’ Certificate (helis or fixed wing) and ’B’ Certificate (fixed wing). Quiz and Social Night Thursday 18th April at Studley Cricket Club. In This Issue Club News The regular round up of club news, appeals, and information about the club and its members. Sopwith Pup The task of restoring the Rushbrook strip to flying status is well under way. The strip itself has been cut and is in surprisingly good condition with virtually no damage from the sheep. The next task is to re-erect the fence so the strip can be protected through the rest of the year. So far the moles have not appeared. Access As with our Tardebigge field we enjoy a good relationship with the owner Farmer George and the poor state of the drive to the field will shortly be improved to allow cars to drive to the strip. Considering the rain in the past 6 months the access and strip are not showing too many signs of water logging or water damage. Field Use It is important that the strip at Rushbrook is used as otherwise we may have to introduce some form of time limited flying which we know is not popular. Clive Cottingham writes about the Sopwith Pup and how it makes such a good R/C aircraft. February Talk Some pictures from the talk in February given by Tony Hooper together with some of the superb models that were brought along. Seen At Tardebigge Pictures of the aircraft and pilots that were seen recently during one of the better flying days.

The last session is expected to be 25th March. Sunday 7th April 2013 First BBQ of 2013 Season and examination day at Tardebigge. There will be an opportunity for members to be evaluated for their ‘A’ Certificate (helis or fixed wing) and ’B’ Certificate (fixed wing). Quiz and Social Night Thursday 18th April at Studley Cricket Club. If you are interested in any events, or have suggestions for future events, please contact Paul Dudley on paul.dudley@hotmail.com or Tel 0750 8029795 Club Trainer The club trainer, that was supplied by the BMFA for training purposes, is maintained and stored by Paul Dudley. It can be used by any member who wants to develop their powered aircraft flight skills. Please contact Paul on paul.dudley@hotmail.com or Tel 0750 8029795 to book some time with the trainer. Weather Station The weather station at Tardebigge field can be contacted on 07501841025 to check the weather before you set out to fly. There are ongoing problems with the detector so don’t blame me if it says there are people at the field when there are none. Rushbrook A team of members led by Stuart Clitherow (clitherow@3cc.co.uk) are now flying regularly at the Rushbrook field and maintaining it. They have widened the strip making it even more accessible and would welcome any pilots to use the field. They are always looking for help with the maintenance so please contact Stuart if you are prepared to spend a little time ensuring the continued use of this site.

Published by North Worcestershire Model Aircraft Society www.nwmas.co.uk Club Forum http://nwmas.proboards.com/index.cgi 2 North Worcestershire Model Aircraft Society March 2013 World War I Aircraft suitable for R/C..1 I have started this series of WW 1 aircraft with the Sopwith Pup. I make no apologies for this aircraft being very well known to Modellers. The full size had a reputation for being a Pilot’s Plane, so most modellers will think it can also be a good modeller’s plane. A Looker When you look at the Pup it ‘looks right’. The American’s would call it ‘cute’. It also has an engaging simplicity. The Sopwith Designer, Herbert Smith, had the knack for simple efficient design, a bit like two well known freeflight model designers Bill Dean and Vic Smeed (for those of you over a certain age – modelling in the 50’s and 60’s). Chris’s Southerner is a Bill Dean Design. Origins The Pup was developed from a small biplane built as a ‘runabout’ in Nov. 1915 for Harry Hawker, Sopwith’s chief test pilot. After the war Tom Sopwith and Hawker renamed the company H.G. Hawker Engineering. Harry Hawker died in a crash in 1921 and the company was renamed Hawker Aircraft in 1933 – the rest is History as they say!. Pup with Bite When you look at the Pup, it is hard to believe that such a gentle looking plane could be so successful as a Fighter. Many modellers read stories of the Pup being used for Naval experiments of Deck Landings and it being the favourite of Instructors in UK Training establishments who painted them in multicoloured patterns. The aggressive side of the Pup is sometimes forgotten. It did shoot down over 240 German planes and probably many more that where not confirmed. Performance When introduced in October1916 by the Royal Navy Air Service (RNAS) the Pup was superior in flying ability to it’s opponents, but it always suffered from being ‘out gunned’, as it only had one machine gun. When you consider it only had a 80 HP engine and by 1917 the Germans were flying with the 160 By Clive Cottingham HP Albatros D111, it’s performance was quite remarkable. Success RNAS Canadian ace, Joe Fall, scored 11 on the Pup with a final total on Camels of 36.The RNAS were the first Service to use the Pup. Fall had an outstanding day on 11 April 1917, when he shot down 3 Albatross D11’ s in one combat. The painting below shows him after downing his second victim. RNAS pilots were particularly aggressive and successful. They had a number of highly successful Canadian pilots in their ranks. Take the Fight to the Enemy If you read Arthur Gould Lee’s book Open Cockpit (still available from Amazon), he vividly describes fighting the Jastas in 1917 with the Pup. The Pups always tried to fight at 15000 ft or higher, as they could out manoeuvre the Albatros D111 at that altitude. However it could never run away to safety, as it was considerably slower and the D111 could always out dive the Pup. This also applied to the majority of German 2 seaters. The bravery of these pilots can really be appreciated when they are in combat and know they cannot run away! An added problem was the prevailing winds, which were predominantly from West to East. The British RFC High Command gave strict instructions to the Pilots to always take the fight to the Germans. The patrols Published by North Worcestershire Model Aircraft Society www.nwmas.co.uk Club Forum http://nwmas.proboards.com/index.cgi 3 North Worcestershire Model Aircraft Society March 2013 World War I Aircraft suitable for R/C..2 also had to be 2 to 3 hrs long, otherwise questions would be asked!! Many combats took place well inside the German lines, which were in the East. So the Pups had to fly back after combat against the wind with a plane that was shot up and/or had a rough running engine. Sopwith Camel The Pup was superseded by the Sopwith Triplane, which had a 130hp Engine and this in turn was replaced by the famous Sopwith Camel. Modelling a Pup As a Flying Model the Pup is very straightforward. Simple box section Fuselage, Constant chord large area Wings, very large Stabiliser area for easy C of G positioning. There is also a generously sized Rudder and Fin. Clive’s Plans I have produced some plans for a model that can use the Flair Puppeteer Aluminium Cowling (6.75 inch dia), as this is the one item that is difficult to make. The Pup’s Cowl dia is 39 inches so this gives a scale of 1/5.78 which is slightly larger than 1/6, but you can still use the Williams Bros Vickers machine gun at 1/6 scale. However you will need to make a set of wheels as the model dia is 4.77inch. British WW1 Fighters had 700mm dia wheels (27.56 ins). Flair Puppeteer wheels are 4.375 inch dia., so they should be 4.593 dia at 1/6. These will not look right on a scale Pup, as the wheels are part of it’s character! As far as Engine size is concerned a 48/52 Four stroke would be ideal. It may even fly on a modern 30FS if you are good at building light. This plan is the basis of my RC Scale drg. for the Model. The eagle eyed among you will see that the plan is actually for a rubber driven Model. Now there is an indoor challenge for you Chris!! However these FSI Rubber plans are very accurate and scaling up is quite easy. It is just a matter of using appropriate wood sizes and quality. There are a number of FSI 1st War plans on the Outerzone Web site (www.outerzone.co.uk). This is an excellent site for all types of plans and they are free!

Chris’s latest old timer with real Mills .75 diesel. Maurice’s Mew Gull Parts for Rob’s own build engine Chairman of Bromsgrove brought along hist latest scale model of a Harvard. Published by North Worcestershire Model Aircraft Society www.nwmas.co.uk Club Forum http://nwmas.proboards.com/index.cgi 5 North Worcestershire Model Aircraft Society March 2013 More on Maurice’s Mew Gull Maurice inherited this aircraft from Gary Fisher who obtained it from Paul Dudley. Maurice says of it “It is 62.5 inch wing span and weighs 8lbs. The fuselage and tail surfaces are all balsa covered in fibre glass and painted. The wing is normal open structure covered in Oracover. I have fitted a ASP91 Four Stroke with the exhaust fitted within the cowl.” Experimental Aircraft Peter Seddon Published by North Worcestershire Model Aircraft Society www.nwmas.co.uk Club Forum http://nwmas.proboards.com/index.cgi 6 North Worcestershire Model Aircraft Society March 2013 Seen at Tardebigge Published by North Worcestershire Model Aircraft Society www.nwmas.co.uk Club Forum http://nwmas.proboards.com/index.cgi 7
