Unfortunately, I have to start this edition with the sad news of the passing of two club members since the last edition; John Sexton and John Hills. Both were long standing, active club members who will be sorely missed and I’d like to extend my condolences to both families. So far this year the weather has been very challenging for flying. It seems that mother nature has been teasing us with rain when the wind is calm and blustery conditions when the rain abated. Despite the challenges, there have been plenty of club members braving the conditions to attend the club patch and other events. As we head into July, it finally looks like we will be having an extended settled period and I hope to see as many of you as possible during the summer. While I write this editorial, my car is stacked to the roof with models, ready to head for the patch after work tomorrow. We’ve had a few club events since the last edition of the newsletter and our chairman has kindly provided articles about the second indoor flying event and the Fenn Brothers competition as well as providing details of John Hills’ models which are for sale, with proceeds going to the St Nicholas Hospice. We also have an article from Pete Loxham about his serendipitous spring of flying and related events, triggered from his kind offer to help yours truly at the Rougham LMA show this year. Colin Dews has also provided another amusing tale in the saga of his Graupner glider, which seems to lead a mischievous yet charmed life! Page 1 I’ve also included a short warning from Dave Fisher about a problem he has experienced with a Futaba 6EX transmitter. April Indoor Event For the second time in 2013, NMFC members gathered at Moulton Village Hall for some informal indoor flying. If you have not participated before, there are no rules, apart from fly safely and you can fly anything you like as long it is going to be safe in the confines of the hall. article by Mike Cox Ian Hatton kindly ran the round the pole activity, there is only one goal, knock the other model out of the circuit any way you can. There are two ways I know of disabling the other model, either creep up from behind and chew off the tail with your propeller or dive from height onto the other model, both methods can be as harmful to your model as your opponents, but it is great fun and requires no serious investment. Kevin was very creative with his own design delta, this time it did commit RTP combat in action! flight and was extremely fast. Young friends of John James joined in as usual (sorry no names, I forgot to ask) and enjoyed the RTP as well as their own helicopters. There were several helicopters as well as quadcopters, mine even has a button you press to perform a back flip. If you have not seen these before take a look on youtube at the following clip, very impressive:http://www.youtube.com/watch?v=_sUeGC-8dyk This time Jerry came along and treated everyone to some delightful home made pancakes with various fillings, yum.. my favourite was with syrup, not that I should be eating that! Another fun evening for all, do come along next time. Futaba 6EX diode issue I had a lucky escape, using my transmitter, it bleeped at switch on and then appeared to work OK. I flew my old Wot4 and after landing, the transmitter bleeped a couple of times, showed a very low voltage, around 7.5v and switched off. I said a few words about batteries and went home. Checking the pack it read fine, so I put it back and again, the same voltage problem and it switched off. I put the battery pack on a 21 watt car lamp and it was fine. Looking inside the transmitter, diode D2 was burnt out. At least one other person on the internet reports the same part failure. This diode appears to feed the display and maybe the modulation. The red and green lights on the RF board still work, so I guess the RF is working but with no signal. article by Dave Fisher Page 2 A failure of this part would be a disaster in flight. I can only guess the part is not specified correctly. I have fitted a "similar" diode and tested the transmitter and it appears OK. I will do a bit more testing before I fly but as the original diode would have caused a crash, I’m not sure why I need to worry. I have emailed Futaba to see what they say. article by Pete Loxham From the Ridiculous to the Sublime Why did I agree to do it I asked myself, standing on the stall of fellow flyer Kevin Sale who had decided to branch out with his skill and equipment and purchase a small area at the Rougham Show to promote Hawk Graphics (that’d be me then - Ed). Having travelled from Newmarket on a cold and blustery day, arrived at the site; directed, due to the “Exhibitors” badge towards my own private parking area. I was so impressed, and looking round to see if anyone I knew was watching me, that I nearly ran over Alex Whittaker from RCM&E, who was wandering over to the flying area with camera and note book in hand, clearly unsure of the correct direction. We exchanged smiles as he slid from the bonnet of my car, none the worse for the experience, as he said later and I arrived at my appointed parking position. Kevin had been at his stall ages and was all set up and eager to greet his new found public, and hopefully customers. It was still grey, cold and windy, but his enthusiasm was boundless and we settled down for a long and cold day. A few members of our club wandered past. Some seeing us and others may or may not have done so, but the flying was good and the stalls were reasonably busy for such a day. Day two started much better and the sun shone in the morning and more people, members and stall holders ventured out, including my pal Alan who had come up from Stortford for the day. Again the flying displays were inspiring, but alas the grey descended once again and the cold set in. This made my conversation with Alan turn to warmer thoughts. Page 3 Now he has a place in Denia in middle Spain. I have a much smaller interest in a place on the Costa. He has room to keep planes; if I played my cards well, I had a small space in a wardrobe! We wandered the stalls, looking for a “Plane in a box”. It had to have everything included, Chocks away! as I had no intention of taking items backwards and forwards to Spain. Well a few stall holder conversations later, and we narrowed the choice down to which FMS Mini Warbird I would pick. In the end I picked the P47. It really was an “in the box” plane, with everything I would need to assemble it in Spain, apart from a small charger and I had a spare one of these. All I would then need was a small bottle of super glue. So on to warmer flying conditions, and plane duly assembled in about 30 minutes, off I went to the beach with reluctant good wife in tow for moral support. All checks done, and a small crowd assembling, I took a deep breath and launched. She went up like a Saturn rocket! The tail looked nice and flat but clearly not! Adjustments made and off we went again. First two flights went well, but on the third she glided on the final approach for ever, no option but to go round, but this little bird had other ideas, as I opened the throttle, a little too quickly, she went down and left and hit the deck. Now the 3 blade prop looked brittle and so it proved! The advantages of the web really came to the fore, and Noel alerted back in the UK, found Wheelspin Models, they had a 2 blade version that would fit, or so it said. Ordered and sent to some friends who were coming out to stay with us for a few days and the new prop and friends duly arrived. Well fit it did - not, but after a number of attempts to rectify the fitting, including using some cut up wine bottle corks, which I had accumulated quite a choice of, I found an old Spanish tap washer in my box of bits, with just the right size hole, and the right thickness and it did the trick, result! So on yet another blue and warm day, off we went to the beach. All checks done, or so I thought, and away she went. Left! Despite all my efforts, she hit the sea wall and broke the wing! Bigger bottle of superglue later and she was back as new, the advantages of flying chip boxes; but still I did not know why she had attacked the sea wall. On closer inspection I found that with the first crash the fuz had bent, only a little, but enough to send it in only one direction. The disadvantages of flying chip boxes. Still with a hairdryer and some careful work, she was back straight, I hoped. Following day, back to the beach, big gulp, as yet again a crowed had gathered and off she went. Three flights later, still in one piece and answered as many technical questions as my limited Spanish would allow, we walked back home. As we crossed the street, a young road cleaner approached us and asked, in Spanish, if we had a good flight, I said yes, and he said he too did some flying and then said he was the current Andalusian champion for 2012, then produced his phone to show me the picture evidence! Now what are the chances of that? Where was Alex Whittaker when you needed him? I have now discovered that there is a flying club a short drive away and this is on the things to do the next Andalucian 2012 champion, apparently! time I am in Spain and see blue skies! Page 4 article by Colin Dews During a flight at Snailwell on Thursday evening June 6th, my Graupner electric glider developed a problem with the elevator circuit a few seconds after launching when the model began to perform a series of uncontrollable violent loops. Graupner Great Escape At the time, the wind was blowing from the NE and as the model was rapidly being blown towards the A14, I decided not to kill the motor or deploy the tail parachute until it had crossed the road. By that time Colin Ashman had taken control of the model and we decided to keep it airborne until it was well clear of the British Racing School’s property. After closing the throttle, the model was soon out of sight below the tree line but we were able to take an approximate bearing of its flight path (down wind). On the way home from the patch, I did have a look for the model as I went along the Snailwell Road to Newmarket, stopping where I imagined it would have crossed the road near some cottages. There were lots of trees around and I soon gave up my search and realised that unless the model had landed in one of the fields and that some kind soul picked it up and contacted me, I would probably have to wait until the winter months and make a closer look in the trees. You can imagine my p l e a s a n t surprise when a lady from the Stanley House S t u d o n Fordham Road phoned me to say she had found the model near her home and noted my name and address on the Fin. It had fallen from one of the large Horse Chestnut trees that border the avenue leading to her house during the high wind on Sunday 23 June, 17 days after being launched from Snailwell. The next day my wife and I called to collect the model, thank the lady and leave a reward. The model was only slightly damaged with a couple of dents in the Port wing and a U/S LiPo battery. Even more remarkably, the cockpit canopy had remained securely closed and no rain water had entered the fuselage. A close examination of the elevator circuit revealed that the cleat had broken free from the plastic push rod and remained still attached to the elevator horn. The end of the thin plastic push rod was badly frayed and the outer of the Snake had become detached from the fuselage and was able to move freely allowing significant sideways movement on the push rod/cleat connection. No doubt that this was the prime cause of the fracture. However, I must blame myself for not carrying out a thorough inspection of the model before the flight when these problems should have been spotted. Page 5 The model is about 20 years old and has caused me concern on several occasions during the last few years with peculiar unexplained flight maneuvers such as pitching oscillations at certain motor settings even when the stick was being held steady. The outer of the Snake has now been securely glued to the Fuselage at both ends with Araldite and I hope that has fixed the problems for good. Fenn Brothers Competition This Sunday 16th June the usual suspects gathered at the Rowley Mile for the annual Fenn Brothers glider competition. The weather did not look promising with rain forecast for later in the afternoon with lots of cloud and little sun. Colin Dews predicted rain at 4.00pm I will leave you to guess the time it came! article by Mike Cox The bungee was laid and test flights done so the competition commenced around 1.30pm. First up was Colin Ashman with his old faithful Diamond Cloud but the air was cold so the flight was less than 3 mins though he did gain the 100 point landing bonus. Peter Ashman followed with his Amigo IV, a wonderful old style built up glider, the design I first learnt to fly on. The Amigo was a little light for the conditions and the strength of the bungee so the flight lasted 69secs and no The competitors landing bonus. Colin Dews came along with an Eliminator, a new model to me and managed 2 mins with the landing bonus, not a bad flight for a model that had only been flown once before. Robert Hills, our treasurer was up next with his Nebula, he has won the competition previously with this model and straight away he was in lift. This flight culminated in almost a maximum at 9mins 42secs and the 100 points for landing in the circle. After an absence last year Cyril Mann was back with his ancient Gentle Lady and straight into the same lift as Robert to give him a flight time of 8mins 41secs and the landing bonus. The weather continued to be mixed with warm and cold conditions blowing through. The second round gave similar flight times for most competitors between 2 and 3 mins, I managed 4 mins with the Ava but Colin Dews topped the round at over 6mins though missing out on the landing bonus. Round 3 was very much the same for everyone (2-3mins) except I, some how managed just over 8mins and the landing bonus. Round 4 got off to a better start for Colin Ashman with a 4 minute flight and the bonus. Peter Ashman then beat that with 5mins 26secs with a much better launch from the Amigo. Colin Dews again exceeded 5 mins but this time Robert Hills luck ran out with a sub 2 minute flight. Cyril Mann finished the day with 2mins 25 secs and 100 points for landing in the circle his second of the day. My final flight was ok at 3mins 20secs with the bonus. The final scores were as follows:1. 2. 3. 4. 5. 6. Mike Cox – Ava Cyril Mann – Gentle Lady Robert Hills - Nebula Colin Dews - Eliminator Colin Ashman - Diamond Cloud Peter Ashman - Amigo IV – 1641 points – 1200 points - 1168 points - 1148 points - 1147 points - 774 Points Rather annoyingly the weather cleared as we finished the competition allowing other members to join in for a bit of fun. Jerry and Shane Carter appeared with a couple of Trevor Gouch gliders to show us how it should be done. The last I saw of Colin Ashman his Diamond Cloud was up there with the clouds and well over 1000ft. Overall everyone seemed to have a good day and I hope for next year we can encourage a few others to join in the fun. Finally many thanks to Jerry and Shane Carter for coming along for a bit of fun and presenting the winners with their prizes. Page 6 Eric and the remains of his Pitts biplane.
