I build a lot with depron and recently bought a few tubes of foam safe glue from HK and it is really excellent. Much lighter than polyurethane and very cheap. **LINK** As a club we buy our depron in bulk from; **LINK** We charge our members £2.35/sheet which is our delivered cost. Smaller quantities available from; **LINK** Rob

If you think about this; Force of impact=mass x velocity Wood and foam will have some level of plasticity. When you exceed the plasticity it will break. I have recently started designing based on existing designs and have a few observations. 18 months ago I designed a composite fuselage slope soarer off an existing design (Charles River Radio Control Club LS1 (La Sierra 1) also copied by Sig as the Ninja). By working formers I was able to make sure frontal shock was taken in the wing seat which is able to bulge outward on hard landings. Adding any form of bracing in that area resulted in damage before or after the former. Last year I designed a club contest model. The design parameters were cheap, small and reasonable cost. The design is based on the Das Ugly Stik. 31" wing span with cruciform depron fuse, balsa battery box inside the fuselage sides and a depron armin wing which provides a semi-symmetric wing section. The auw weight is all of 450g and capable of speeds up to 55mph. Total cost with all the gear £50. You would think that it would only fly in calm conditions. We fly them in wind speeds of up to 20 knots and they handle turbulence really well. There are around a dozen in the club now and they are almost indestructable. They can do almost all the aeros you want and we crash them a lot. Normal failure is just the motor mount. Glue in a new motor mount and you are good to go again. Again I think the secret is allowing the impact forces to be released in the wing seat. They are probably the most popular model in the club at the moment for fun value. Rob

A similar question was asked a few days ago. You have to specify the path to the folder in the settings having copied the contents of the SD card to the folder on your pc/laptop

The path to the files is under settings. Go to Settings menu look for Settings and then enter the location where you saved the contents of the SD card. Mine is still 2.0 and says Sd structure path but it will be similar. Rob Edited By TigerOC on 17/10/2016 22:24:37 Edited By TigerOC on 17/10/2016 22:24:56 Edited By TigerOC on 17/10/2016 22:25:30

This supplier may suit you better.; **LINK** They have a range of packs. Rob

If you're a beginner you'll find the powered Zagi very challenging unless you have previous experience. Rob

May I just add another factor to this. You might have heard of a new project that has come to the UK called Men in Sheds. This is a project to get retired people involved in doing things and encouraging them to socialise with others because so many men retire, vegetate and die early deaths. Our club is largely retired men. We have 2 members who have recently had serious health issues. Both members have told me that they don't know how they would have coped with their situation without the help of other members and being able to get out and enjoy time with their mates doing something they love. Rob

If you are using the HK crimper I have a few tips. 1.The ideal swg is 26. 32 invariably fails 2. Do not be tempted to wick the end with solder as it weakens the wire. 3. The crimper has 2 crimping notches. Use the outer as the primary and the use the secondary inner notch. It compresses the crimp really well and makes insertion into the housing a breeze. Rob

We had a similar situation here recently when one of our members flew a glider into a cloud and lost it. 2 of our members also fly quads so these were deployed the following day to find the wreckage. Sadly one of the quads suffered a motor or ESC failure and went down. The second quad found the glider wreckage. The score was £200 glider write off and a £600 quad. Never found the quad in deep bracken. So there can be good results and really bad ones. Rob

Acrylic paints will be fine like these from BRC; **LINK** Just a tip. I bought one a few months ago and the motor mount is not the strongest out there. Even mild nose overs or putting it into long grass can loosen the mount. I re-enforced mine with balsa inserts on the up right legs on the mount and injected polyurethane glue into the upper portion of the mount (bottom from the battery compartment access hatch) Rob

You could give it a couple of coats of water based polyurethane (Ronseal diamond hard) which will both give a hard surface and reduce hanger rash and with 400 - 600 grade wet sanding provide a beautiful surface. I finish my foam core/balsa sheeted wings with 18g fibre glass cloth and WBPU and they are very strong and have a superb surface. It doesn't add much weight either. 60" wing glider wing this added 20g. Rob

Posted by Percy Verance on 19/07/2016 21:21:01: My bit of friendly advice would be to forget about rolling loops, or rolling anything else. I'd get those landings perfected Sam, because there's a landing after every flight! The other stuff is pretty much optional, landings aren't....... Awesome Percy. The AW is not the easiest to land either. I am a relative rookie, along with a few others in my club and we spend hours doing circuits and bumps. Looks like Heathrow with the models line astern on their approach runs. Rob

I have recently started flying the AW. They certainly need to be flown with some speed and do become unstable at low speed. There is one characteristic not mentioned so far and that is the effect of the rudder on this model. See this thread; http://www.modelflying.co.uk/forums/postings.asp?th=71581&p=1 My first experience of this was on a landing approach on the first flight. Decreasing speed and rudder input caused it to dive rather spectacularly. I have not experienced what you have but do keep the speed up. I have experienced the same spin with a Middle Stik which was purely due to a stall at too low a speed. Diagnosed by an examiner standing next to me. Rob Edited By TigerOC on 16/07/2016 08:52:16

Slough website is taking a while to respond. Hobbystores is giving a server error related to the database its driven by. Personally I think that this is technical issue on their server which nobody has managed to either pick up on / unaware of the problem / tracing the problem is proving difficult. Alternatively the server hosting the site has gone down. The telephone could also be an automated redirect run by the same server and hence no answer. The number given, is one that I recognise as a redirect number as technically its a London dial code. Rob

Good stuff Kenneth, pleased to hear its worked out for you. Rob

Kenneth, you have set a switch to activate/de-activate master? Rob

If you have installed Open Tx Companion then start the app and once you have it running do the rudder + aileron trim switch towards each other while powering up and then connect the usb cable from the tx to the computer. On the left hand side of the app is a line of icons. 2nd from top is download models from tx. Select and all the models will be transferred from the tx to the computer. follow this guide; http://seancull.co.uk/2014/06/26/configuring-the-taranis-trainer-buddy-box-functionality/ when finished the top left icon is save to tx. Select and then it will ask for confirmation. Accept and it will show updating tx and done. Rob

Can you see the trainer option at the bottom of the model page? So you need to activate each channel (on) in the same order on each model (master + slave). I think you need to use a custom switch to activate the channels now which is done in Open Tx Companion.

Kenneth, Option should be available to set on the tx. Switch on; short press Menu brings up models list; select model with right side keys; in the relevant model short press page brings up Model Setup and at the bottom of the page is the Trainer option.

Great video, thanks for the link. Can relate to this. We have had our first junior members for a loooooooooooooooooong time. They are so enthusiastic and having material like depron available for them via the club and also a club trainer and someone in the club prepared to work with them is great. We have a school teacher who has taken these kids under his wing. We are also looking and schools and other organisations doing things like Duke of Edinburgh awards. Cheap materials, budget radio gear, tuition in building and flying and make the whole experience and fun. It also integrates with the their education because they can see maths, geometry and tech education at work.

We already have appointed persons and clearances for this in the club. We encourage a parent to be there anyway.

Perhaps we should view this from a different perspective. BEB alluded to it in his second response. From jargon I learnt managing large organisations years ago. Don't look for the challenge posed but rather look for the opportunity presented. Our club probably has the same age profile as virtually every other club in the UK; largely elderly, mostly retired and mostly inspired by the exploits of the RAF in WW2. We have had 2 juniors join the club in the last 2 months. They are the first juniors outside of club member's families to ever join the club founded in the 1990's. Both entered through MR. Both have had the opportunity to see other aspects of the hobby and are hooked. One of them is 7 and in one month has designed his own glider made of depron sourced through the club and it actually flies. This little lad is so excited and inspirational. One of the members hooked him up on a trainer at the club fun fly last weekend and he was so thrilled by the opportunity. Suddenly his MR's, which he flies well are boring, because he is now challenged by something new. Whether we sustain their interest for life is another matter but through MR he is now being exposed to all the facets of our fantastic hobby. We are taking part in the Drone Aware event with an event next weekend. We had an article published in the local paper this week and already have had enquiries from people interested in what we have to offer. Rob

Posted by ChrisB on 12/04/2016 08:10:15: As I see it, the aim of the questions is to enable the candidate to demonstrate to the examiner that they have an understanding of aeromodelling beyond that of the actual flying element. The aim of the achievement scheme is to enable individuals to gain a certificate, at the moment, purely voluntarily and for fun. Whether the ANO is passed in parliament or whether its secondary legislation enacted by the CAA as part of its legislative powers doesn't really impact on the outcome or aim of the question, that being, to ascertain if the candidate understands the basic background to the ANO...i.e. its the legal order by which all flying is regulated. In my view it matters not whether its primary or secondary legislation and I think its splitting hairs in the context with which we are discussing. As long as a candidate understands that its a legal framework controlled and regulated by the CAA by which aviation including model aircraft are required to observe then I think in the context of the voluntary certification scheme that is a sufficient minimum answer. CB You are absolutely spot on. The whole point of the exercise is to encourage the student to be aware of the law that governs what they can and cannot do. Its about encouraging learning and awareness not about passing exams with absolute technical detail. In this hobby environment we want participants to be aware of the law in broad brush strokes, not people fully qualified in the legal complexities of aviation law. For example ANO 137 & 138; why should it be necessary for the individual to know what each says when it sufficient for the individual to be aware that it is unlawful for a model flyer to wilfully endanger people (on the ground or in the air), property including buildings, aircraft or animals.

Posted by Jon Laughton on 11/04/2016 22:24:02: Thanks TigerOC - but why does it have to be that complicated ? Andy Symon will no doubt let us know..... Not sure why the author of the page used "frames". This is a very old method of embedding pdf files in html pages. Presume they couldn't be bothered moving the content out of the pdf file and putting into html format. With the relatively new cascading style sheets this is quite a simple process. But ............................
