I would suggest you just add a link to our Club website as there are other articles, videos etc there that your members might also find interesting. Check out the Articles webpage. Dumfries Model Flying Club https://dmfc.org.uk

I wrote a booklet on the Basics of Electric Flight which can be downloaded from our Club website. The link is here:- https://dmfc.org.uk/downloads/electricFlight.pdf

Thanks for the input guys - much appreciated. Three of us have got our heads together to try to resolve this problem and two of us have successfully installed the Lemon Stabiliser Plus in Wot4s, but never in a flying wing. We are beginning to think that a flying wing is just not a suitable platform for this stabiliser. If any of you actually have it successfully installed in a flying wing, I think you could make a lot of friends on YouTube because a working setup including "Panic Mode" specifically for a flying wing is not on YT. I think we had already covered all the procedures suggested so far, but no doubt we'll have another go and repeat them all. Of course the other possibility is a faulty RX/Stab. Thanks again to all.

We are having trouble setting up a Lemon Stabilser PLUS receiver on a flying wing with a Spektrum NX6 transmitter, and wonder if anyone has had similar experience or can offer help. We know that elevon stabiliser settings must be set on the receiver using the dip switches, and not on the transmitter. Works fine as a RX with stabiliser off. Also OK with standard gyro stabilisation mode, but erratic responses for the "Panic" Auto-recovery mode. Seems to recover laterally, but then goes into a steep dive. It seems as though the aileron stabilisation is operating but the elevator stabilisation is intermittently erratic. Any ideas?

Overlander also do inrunners.

There is no disputing that many people use Facebook and enjoy it, but that doesn't change the fact that there are also many who regard it (and some of its its terms and conditions) as objectionable and won't go near it. In my view, an organisation like BMFA with a well-established website should use that as its main communication platform. I have no problem with them using Facebook as well, but I, for one, won't use it. I regard the security of my PC too seriously - and for that matter I won't use Zoom either.

Thanks Simon, but I (and I'm sure many others) would not go near Facebook with a proverbial barge-pole - please put a bulletin on the main BMFA website.

Hi Rich, well as you know this is a very small little beastie, so it's all a very tight fit under the cockpit! All the "bits" were bought from HobbyKing. It flies on Turnigy 2S 180 LiPos and the battery fits into the scooped out canopy, above all the other electronics which are taped into the scooped out cockpit below. The motor is a micro 1712 2290Kv 3.5A 9.2g The ESC is a 6A (Brand X) and the RX is a tiny Orange DSMX for Spektrum. The prop is a GWS 4530. The servos (all 3 of them) are Turnigy1370A 3.7g. Hope that helps.

Well if it's the same one I've got (I actually bought two) it only cost £3.99 so worth the risk. Hot water sometimes does the trick with EPO foam, but can spoil the surface a bit. If you are planning to "electrify" it, it makes a great little powered glider. Flies a dream and can even cope well with some wind. Mine is full house but I straightened the trailing edge of the tailplane and added an elevator made of EPP (a bit of packaging from another model).

I have used 4mm gold connectors on my batteries ever since NiCd/NiMh flight packs were the norm, and all that time I have used a very simple system using round and square section wooden plugs drilled with a blind 4mm hole, and one or other of these is fitted to the negative (male) connector. Round for freshly charged, square for discharged. Being wooden plugs they also form an insulation so that they eliminate any chance of the leads shorting out in transport or storage. So I always keep a handful of square ones in my pocket, and after every flight I fit a square block as soon as I disarm the model, and when I recharge the pack back home I change this for a round one. Very simple and effective. I know some folk who use red/green fuel piping in a similar way.

I can recommend the Lemon 6ch stabilized DSM2/DSMX receiver with diversity aerials. You won't need the Gear channel on a Chipmunk so you can use that for the flaps.

I often see cavalier attitudes to handling armed electric models (eg. carried back from strip still armed with prop against stomach). Eric's scenario above begs for throttle cut to be set immediately on landing. Other accidents waiting to happen are scarves in cold weather. On the field I've also pointed out the danger of people leaning over armed models (or while starting i/c models) with loose tee-shirts hanging outside trousers in warm weather. I used to work for a company that sold fire-safes among other things. A very difficult item to sell to people that have never experienced a fire!

Thanks for all the input guys. Actually the more I've thought about it, the logistics, parking, safety and organisational issues of a true Open Day (to the public) filled me with dread, especially as the numbers attending would be totally unpredictable. On the other hand, I would like to leverage the BMFA Flightfest concept to hopefully attract potential new members and generate local press interest. I'm starting to think towards perhaps inviting a local over 50's group (which I think is the most fertile source of new members who'll stick with it), or perhaps one of the numerous local camera clubs. That way we could predetermine (and limit) potential take-up for the trial flights, and the other issues would be more easily manageable.

With the BMFA Centenary Year and "Flightfest" Open Days in mind, as the P/R Officer of a small club I am concerned about the logistics and planning issues - car park space, unpredictable numbers, catering issues, safety, kids, dogs and a myriad of other potential issues. I would be grateful to any other club members who have useful knowledge or experiences they could share - (good or bad/ dos or don'ts).

I've had a Lemon stabilsed RX in my Mk1 Wot4-FoamE for a few years and never a problem. I can switch it on and off with a TX switch and only use it in windy conditions. You can see the gyro working hard then, as we get a lot of wind shear and down-draughts at our field - especially with a southerly wind. Great for cross-wind landings in high wind too. I have tried a similar setup in an aerobatic model with large control surfaces but this was so tricky to get the gains right that I went back to a standard RX. However not sure what you mean above Denis - moving the model on the ground is how you test that it is working, and to help set the gain. If you get no response from the servos when you pick up the model and jerk it around the axes, then in my view it ain't working and the gains need increasing.

You can buy foamboard from The Range or from Hobbycraft.

These any help? https://www.nexusmodels.co.uk/e-flite-15-size-90-degree-main-eflg1590m.html If not, I might have a pair. They are angled but I don't know to what degree angle as it's not marked.

There's a film called "Ships with Wings" on at 1.20pm on the TalkingPictures channel today. It's set in the wartime Fleet Air Arm and although the film storyline is tripe, it contains some rare footage of Fairey Fulmars and Blackburn Skuas, as well as Swordfish. The Fulmar and Skua in particular are rarely-modelled aircraft.

There are some booklets you can download, explaining various aspects of electric flight here ... https://dmfc.org.uk/articles

I think we too often underplay the social dimension and health benefits of our wonderful hobby. https://dmfc.org.uk/theSocialDimension

We got the announcement from SAA but where can the above map be accessed? Sorry I see the link but it was marked as not available in the forum thread. However I have now been able to access it.

A newbie at out club has the NX6 and it seems fine in terms of its functionality, but to be honest I much prefer my (old) Spektrum DX9. Reasons (compared to my DX9):- the voice system is barely audible even at full volume, the screen is very hard to read in daylight (and changing the colours doesn't help). Also I don't like the On/Off switch mechanism. There appears to be also some issue with them refusing to charge (which has been raised on some forums) and my clubmate has had this issue which requires disconnecting the battery and then reconnecting it after a short pause. I would certainly not recommend any of the DX's suffixed with an "e" as they leave out some of the most desirable features. I believe the DX9 is still available and if my current one packed up that's what I would go for. As far as receivers go, there are Lemon DSMX-compatible receivers both with and without telemetry which are excellent and much less expensive for similar features. They do compatible stabilised receivers too.

For what it's worth I have a DX9 which I've had for years with never a glitch using both DSM2 and DSMX receivers - Spektrum, Orange and Lemon. (Of course the lastest DX9 TX is DSMX only, but my old one is compatible with either but defaults to DSMX if the RX is DSMX-compatible as most recent ones are). This summer I have been training a Newbie who has a new NX6, and my old DX9 has buddy-linked wirelessly to it with no issues at all. Personally I prefer my DX9 (screen is brighter outdoors and voice messages are louder) but otherwise the NX6 seems a very nice piece of kit and it has diversity aerials which is always a good thing. Of course, as has been said, in the EU/UK the NX6 is DSMX only.

Hi Kevin, I still have an RD6000 Sport and an RD6000 Super, plus loads of RXs - but all on Channel 88. Great transmitters. However I picked up that you have converted three of these to 2.Ghz (presumably successfully) and I would be grateful to learn how you did this. I would love to convert mine to Spektrum 2.4 if possible, so any advice would be gratefully received.
