Found the answer. The member had copied the model to set up a new model not realising the RX number transfer was important. So both models had the same RX number. An important lesson learned. Rob

I have asked the person concerned to check whether the receiver numbers in the profile are different or the same. Personally I have been very fastidious about ensuring this is the case.

Am aware of that Dickw. Have a glider tug using an RB10 and 2 RX's bound in one model BUT they are specifically bound to that single model. The question here is 2 separate RX's (X8R) that are bound as separate models.

Just to clarify; this is the Frsky Taranis thread so I assume it's safe to assume I am talking about this equipment. The owner of the equipment stated that the both models have their own receiver number and slot in the TX. Whether he has previously used this RX I am not sure. My question is "model match" on a Taranis defined? This situation says not. Edited By TigerOC on 04/10/2018 10:13:50

Had a strange incident at the strip today. A member landed a model and forgot to disconnect the battery (a no-no yes) and then selected another model on the TX and powered it up. They were sitting side by side. When he checked the surfaces both models gave the same outputs. How is this possible? Rob

i have made a number of foam core wings over the last few years and used Polyurethane wood glue; **LINK** However this does require pressure to get a good bond because the glue foams and will naturally push the surface upwards. So when sheeting I spread the glue thinly on the wood side and spray the foam lightly with water. Apply the sheeting and then place in a domestic vacuum storage bag and apply vacuum and leave for an hour. The bond is amazing and is almost impossible to separate the foam from the sheeting. The foam will break up before the bonded surface. I then glass the wing with 18g glass cloth and water based polyurethane. The wings are incredibly strong. Most of the glider wings I have made are sheeted with 1/32 balsa and I have yet to break a wing. Rob

I have just got a DLE 30 and ran it with the supplied exhaust. Really loud. Bought a Pitts type exhaust from HK and that has baffles and is a lot quieter. It has definitely stopped the bark. A lot of the noise is coming from the prop. We did some basic measurements and got 86db but it was next to a hedge row which is not ideal. Noise is not really a problem for us as we fly from a remote farm field with few neighbours who often come over and watch us flying. A tuned pipe would be much quieter but you are going to pay some big money for a decent exhaust system. Rob

Posted by Robert Cracknell on 09/07/2018 11:22:52: It would be interesting to know if anyone out there has tried to promote model flying specifically at the youth of the country? I am thinking along the lines of inviting the local ATC group, scouting groups to your flying sites or promoting at the local engineering technical college. Many of these organisations look to arrange for visits to local places/groups of interest and they have some of the characteristics that we are looking for i.e. working as a group, working towards bettering themselves through qualification and in some cases a direct interest in aviation! We did a presentation to our local ATC group and invited anyone from the group who was interested to contact us and we would arrange for them to fly. They seemed more interested in "playing soldiers" with parade ground square bashing than actual aviation. The only thing that perked their interest was when the lady inside the Frsky Taranis started talking to me and they thought that was really "cool". Their CO even raised the subject of the RAF training drone pilots. Never had any contact. We have a lad in the club that is registered for Duke of Edinburgh Award and has RC model flying as one of his achievements.

I am Chairman of the Okehampton MFC. A very small town in the middle of Devon. I joined as a rookie after modelling in my youth. We had 25 members (then maximum membership) I run my own Internet server and offered the club free hosting and administration of a website on joining. 3 years ago the club split due to a group wanting to do their own thing and be free of BMFA "rules" and they took the flying site. We found 2 new sites through contacts in the farming community, although we only currently use one of the sites. Apart from one member that returned from the splinter group, all the rest have become members via the club website. We also have 5 members under 16. We run a monthly fun fly, March - October, to get members together. They asked for competitions at these and we designed a small cheap depron machine (£50 total cost) for pylon racing and later introduced a Last Man Down competition for the glider enthusiasts. We have a floating trophy for each event. The members love these competitions which also improve their flying skills. Last year we worked with South West Scale Soaring and organised an aerotow week which attracted a lot of people from all over the West Country. We are arranging another for next month. Like any club, the load is carried by a core of dedicated members. The atmosphere in the club is exciting and most members are more than happy to help each other and get involved. We have a small slope soaring group and we travel all over as a group, car sharing, to fly at at different locations when the wind is in the right direction. Like any organisation, it is only as exciting as the leadership group want to make it. The leadership dictate the mood of the club. Rob

trebor, It is worth using logging. I use the SF switch to arm my electric motors and to disable the throttle on an IC model. The same switch is used to start the log process. This will graph all your values with a time stamp. It is then really useful to go and examine the log file and check your RSSI values using Companion. A large percentage of our club are Frsky users. We have had one member have range issues and that was due to a faulty RF board. It is a rock solid system. I recently had issues with a foamy but it turned out to be a dry joint in the XT connector on the ESC. So well worth while examining all the electrical components in the system. In this case I was using a non telemetry receiver but with telemetry glitches would have shown up in the Rx voltage. Rob

Posted by Steve J on 18/06/2018 07:53:57: Posted by Piers Bowlan on 18/06/2018 05:52:55: On another tack, I have just moved house to the wilds of Dorset. Recently, I observed first a Chinook skimming the trees down in the valley where I live and then a SAR helicopter being operated well below the tops of the Purbeck hills. All very impressive stuff . I wasn't flying my glider as I am still unpacking boxes but had I been, there wouldn't have been a conflict as they were flying well below the height I usually fly! I just hope the pilots in question know their drone code . You might find Airprox 2018011 interesting. Police DJI Matrice and F15. **LINK** Steve The Okehampton MFC operates in the general area as the incident referred to. These fast jets and helicopters are operating in conjunction with ground force training on the military training area on Dartmoor. We have encountered similar instances over the last 2 years. Attempts to contact the RAF air safety unit have been unsuccessful. As a model flyer it is very difficult. Jets traveling at 400mph at 250ft are almost impossible to locate with any accuracy. We know they are in the area and only fly week days. By the time we actually see one it is already on top of us and gone in the blink of an eye. We have implemented a rule that whilst lone flying we stay below 100ft if jets are in the area. If more than one is flying at least one person is spotting. The integration of Drone Aware into the system would make everyone's lives much happier. Our concern is for the crew of these aircraft. A Hawk ingesting a model at this altitude would only lead to one result. Rob

Pete, suggest you let Stan Yeo at Phoenix MP know. He would probably be aware of the owner. Rob

We have a club member who only flies gliders and his main desire is to "speck it". We have lost count of the number lost to date. Last year his son-in-law bought him a Heron for his birthday. We were flying near Dartmoor and he was doing his normal thing and unfortunately it disappeared into a cloud. At this point he put in up and left rudder and we all looked up in the direction in which it was last seen. After 10 minutes nobody had witnessed it come down but we knew it must have returned to earth and we had a rough idea where. The following day 2 members came out with quads with cameras. One was newly built and worth over £1000 with FPV and the other was a cheapish DIY build with a recording camera. Each pilot took a quadrant and set off to scan the area. 5 minutes in the pilot flying his expensive quad experienced a serious malfunction and it plummeted out of the sky from 300ft. The second quad continued while the rest of us went in search of the downed quad. The search for the quad proved fruitless in the gorse. The following day the location of the glider was identified from photographs and we picked up the remains. 6 of us searched for 4 hours for the quad and never found it. Net result £1000 quad lost for £140 foamy. Edited By TigerOC on 05/04/2018 22:43:22

Great to see this added to the forum. Following a successful event organised by our club, Okehampton MFC, with South West Scale Soaring last year there is an increasing interest in this in our club. A fellow club member and I have joined forces to build a tug for smaller gliders prevalent in our club based on the Das Ugly Stik. We are fortunate to have Felix Marten, a well known tug pilot in the UK, as a member and we are using his expertise to guide us. We are hoping to establish a regular monthly event to which everyone in the Devon/South West area is welcome to attend. This is a 2m span off plan version powered with a Zenoah Titan 23cc petrol engine. Here being balanced in preparation for test flight, when it stops raining/snowing.

NATS have already co-developed 'Drone Assist' smart phone app and requested use there of. It would only require a single member at a club site to the have the app running for NATS to be aware of a location where models are flying and shown on a live map.

The beeping is an ESC warning. Have you programmed the ESC? There should be instructions on how to programme the ESC with the model or will be available on the internet via manufacturer website. This also occurs if the throttle is not in the full down position. Rob

That is normal. The TX is in bootloader mode. The firmware update is done with the TX OFF using the Write firmware to radio option; 3rd from bottom icon on the left hand side task bar. The bootloader is used to read/write model configurations to the radio. Rob Edited By TigerOC on 19/01/2018 22:06:47 Edited By TigerOC on 19/01/2018 22:07:32

EPP is more rubbery than other foams and therefore bounces as opposed to breaking. Hence its use in indoor air frames with very hard surfaces. Requires more support than other foams because its so floppy. Rob

Posted by Martin Dance 1 on 23/10/2017 07:45:06: Sorry to pour cold water on the Dremel love in. I bought a mains powered one 3000 IRC from the Dremel stand at a major tool show, it came with a range of accessories at a good price. BUT it vibrated quite badly, but not enough to warrant returning it. This was five years ago. It failed after three years. I sourced with great difficulty replacement switch and brushes, but the fault was the main commutator, very expensive. So I dug out my very old B&D version of the tool and discovered that all the Dremel accessories fitted and it didn't vibrate. I will say all the accessories are well made and work well. Mine failed just after 1 year warranty. Replaced with a Maplin version **LINK** They do not appear to like dust very much. Suspect it gets into the commutators

Posted by Tom Thomas on 08/10/2017 02:41:13: Reflex is a very good point, it's not mentioned in the instructions? What amount do people recommend? Say I had it sat on a table, how many mm's do people generally use? As a start use a ruler and line up with the trailing section of the bottom of the wing. On the Fusion it lines up with the bottom section of the fin but the WT has a much bigger angle so that wouldn't be a guide. This is an extract of the instructions for the Fusion; 12) Connect up the elevens to the servos with the m2 rods and quicklinks with the 'Z' bends in the m2 rods at the servo ends such that with the aileron trim at neutral and three clicks of up elevator trim the elevens should be a continuation of the lower wing surface at the root for light winds, more down trim will be necessary as the wind strength increases. Rob Edited By TigerOC on 08/10/2017 22:17:10

Paul's spot on with the reflex on the elevons. If you can get someone with experience of slope soaring to trim it up for you it will help tremendously. Getting the reflex right is critical or else they are a real handful because they react too quickly for a slope virgin. Once trimmed they're great fun. Learned to fly rc with the sister of the "Thing" the Fusion. Rob

Posted by Tom Thomas on 06/10/2017 21:58:51: I do like yellow and black, but I'm very disappointed with the colour tape, it's horrible to try to get around curves etc. On the nose I gave up trying to get it looking anywhere near neat! I build a lot of foamies, mainly in depron so tape is the covering. 2 essentials; 1) a new scalpel blade 2) meths When dealing with curves; take the tape out beyond the curve and then run multiple slits in the tape so that you can cover the curve in sections. The adhesive always gets on the blade and ruins it. so you need meths to clean it off at regular intervals. An oil stone on hand will keep the blade sharp. Rob Edited By TigerOC on 06/10/2017 22:14:46

You'll need a bottle of meths as well. Tape has a release agent on it. Ideally you need to wipe the surface of the cross weave tape with meths on a rag to remove the release agent. I build a lot of foamies and routinely wipe each strip as I go and never had a problem with the tape lifting after application. Rob
