Thanks all, typo confirmed.

Thanks, it's nice to find a site where FrSKY stuff is sold in the UK that isn't eBay.

Thanks for the help with my binding issue chaps, tried it last night and it worked. I misinterpreted the instructions and didn't think the bridging method applied to me! I'm looking to buy a 3D EPP profile plane to fly with my Taranis. This would ideally use a mirco RX, and presumably would have to be an FrSKY one. Has anyone tried to buy one of these before? Currently the only ones I can find are on eBay and need to be shipped over from Hong Kong. I don't want to be waiting that long! Any recommendations? Edited By Chris Anthony on 30/05/2014 13:12:13

Graham, thanks for getting your son to have a go! My ability to rearrange equations was at it's greatest during my school years. So I trust his judgement, thanks to him too. Simon, I agree with your workings, that is exactly the process I went through. If you could compare your results with what I have suggested, and what is actually printed, can you confirm to me which you are saying is correct? Your final equation seems to match mine, and not the book's. Thanks, Chris

Thanks both. Nice to see some agreement to confirm my (partially existent) sanity. But this is of course a bit worrying, I've never seen a typo in such a revered text before, I hope it's the only typo in there! It's not that one Pat, a similarly titled book though, I imagine the material by Abe is pretty much the same. Edited By Chris Anthony on 30/05/2014 10:34:19

It's late so I don't really have anyone else that I can bug with this, and for some reason I feel an urgency to solve it tonight! I'm being flummoxed by the seemingly simple rearranging of an equation. Can someone bring some fresh eyes on this and confirm to me what's going on please?! Apparently this first equation (next to "By definition" ) rearranges into the second equation (next to "Whence" ). But when I rearrange it, I get the top line as being "Krb-Kfa", or "-Kfa+Krb". The text below goes on to say how 'if the Kfa term is less than Krb, the answer should be positive'. Which actually confirms in writing what my numerator function works out to be, and not what is shown by the printed second equation. Can anyone agree? To be clear, all variables included in the equation will have positive values as standard, no negative numbers go into it. Oh, and if anyone can tell me which book this is from, I'll be mighty impressed! Then they might understand why I am distrustful of a publishing error, and still believe that somehow the problem must be my own. Thanks to all. Edited By Chris Anthony on 30/05/2014 00:22:03

Has anyone bound a V8FR-II receiver to their Taranis? I'm trying to do it, and following the instructions on the FrSKY RX manual doesn't seem to work. Any tips?

I didn't vote, mostly because I can't be bothered finding out who stands for what. You'll get things that annoy voters from any party in power; not everything they do can be good. In a way, they cannot win. With that considered though, I'd say I'm pretty happy with the way the country is at the moment. I pay my taxes, and seem to be looked after enough accordingly. Perhaps I am just naive. p.s. - I just did what everyone seems to do on the subject of politics; gave my own views, without even considering the views of anyone else. Didn't read any of the second page, sorry! Edited By Chris Anthony on 23/05/2014 08:08:39

I'll try the red flavour please!

Thanks all, Jon especially. Great description, I'll try and remember it all. That video was great too, apart from the wrecked model as an outcome.

Thanks both. Bob I've gone for your solution as there is less modification of my current solution involved, fits the bill nicely. BEB thanks for that explanation too, I was unaware of the Custom Functions, and always wondered what GV referred to. There's lots of potential there that I'm sure I'll be making use of in the very near future.

Here's one for you all. I would like two switches to be used in deciding whether something happens. I have a method of achieving this at the moment, but it does have a flaw. This is for a flap/airbrake setup I have on the go. I use Switch E to select between 3 flight modes - normal, airbake, and flaps. Then, I use Switch A to select between 3 magnitudes of aileron offset for when either flap or airbrake flight modes are selected. Switch A is functionless when Switch E is set to 'normal' flight mode (SE-), and there is 0 aileron offset, no airbrakes or flaps. The problem with this set up is that whenever you trim the model, e.g. in the air, it only adds the trim to the flight mode selected. In my case, I added some up elevator trim for the 'normal' flight mode, and this all disappears whenever I select for the airbrakes in order to land. It's less than ideal. I wonder if anyone can think of a way for me to retain the system I have, but without having to rely on flight mode changes in order to make it work?

Still loving this plane. I was wondering what people moved onto after their Acrowot? What would be a good follow on, that is perhaps more challenging to fly, but more rewarding? Personally, I've got plans for a Spitfire, and also want to branch across into 3D, starting with some kind of EPP profile thing. But I'd also like to get a follow on sport/aerobatic model at some point too. A chap with an Acrowot at my club also has an Sbach, which seems to be quite a step up. What do you guys think?

Thanks for the responses all. I'm surprised by how many people don't bother running exhaust gaskets. I lost my original gaskets when my exhaust screws rattled loose during a flight. Since then, I've used a dab of loctite on the exhaust bolts upon refitting. I've also been running without a gasket for the last few days. The seal seems to be good enough to passage airflow from the engine through the exhaust to reduce noise. But there are still slight, but definite leaks of unburnt nitro fuel/oil coming through the mating faces, regardless of how tight the bolts are. I had put this down to variations in flatness of either mating face, which I had just come to expect from the manufacture of the parts. I had assumed that the reason for the gaskets was to account for this lack of flatness in most cases. Don't you guys find your engine runs a lot messier without proper sealing here?

Thanks chaps, I've checked out the J Perkins site, the diagram is great. Here is my engine: **LINK** I'm afraid my descriptions may not have been very good. The screw I am adjusting, assuming it to be the idle mix screw is 46844F, housed in the throttle arm as you describe Peter. What I have assumed is the throttle stop screw is 46825F. Is this correct? Edited By Chris Anthony on 16/05/2014 10:34:13

It is possible. I am screwing the small flat-headed screw that turns along the same axis that the throttle horn pivots around. This screw is seated basically inside the moving throttle part. The engine does seem to respond to changes in this screw's position; in line with the behaviour expected with normal idle screw adjustment that I have read about. There is another external screw sticking out of the carb, with a load of threads protruding with the head, and a locknut on these threads. I have presumed that this is the throttle stop screw, and I haven't touched it. But it's very likely I am wrong.

Well thanks very much Tony, PM on its way

Thanks for the replies chaps. Tony, I couldn't take your own supply of gasket paper mate, but can you remember where you got it from? I think I'll give the automotive sealant method a go for the short term. Presumably it cleans up alright upon exhaust removal, ready for a clean re-application of new stuff upon replacement, etc.. Cheers, Chris

Folks, I wonder if anyone would be able to describe their process of adjusting the low speed/idle mixture adjustment screw. My current method of tuning the idle mixture has been to screw the needle all the way in (with throttle set to 0% on sticks - idle) and then out a set amount, currently 1 turn (360*). From there, I will test, set idle (for 30 seconds) and ram on throttle, see what happens. If it stutters but picks up, too rich, if it cuts, too lean, and I adjust accordingly. But after a few flights, I have found that the screw is moving itself, and the mixture is changing as a consequence. I checked the mixture screw position tonight after having set it originally at 1 full turn out from fully closed, and I then found it at 2 full turns. It was then that I realised that the mixture screw can actually impede the throttle movement, for example, if it is screwed in all the way - the throttle will jam and not turn when actuated by the control wire/servo. Is this normal, and how do you guys account for this when tuning? The main worry I have is why the adjutsment needle has changed position. The engine is an SC52 2s nitro btw, only 2 weeks old. Thanks, Chris

Folks, Where can I get hold of some replacement exhaust gaskets? For an SC52 2s nitro in particular. My LMS doesn't seem to have any. A more preferable solution would be some gasket paper that I could buy, and cut out my own gaskets from to do the job. Or along these lines, have any of you made your own gaskets that you have found to work well from some random household material, maybe cereal box cardboard or something? Any tips would be appreciated. Cheers, Chris

Lipo's are safe pal.

No apology needed for the length of the post Jon, it was all good stuff that I enjoyed reading and learnt a lot from, thanks for taking the trouble to type it. What you say about flaps and elevator trim makes perfect sense to me. And it turns out I have heard of PIO, just never heard it referred to as porpoising before - interesting! I know on occasion I have caused it myself during a flight or two with my trainers. What you say about the limitations of replying on expo is also very interesting to read. I have been wondering what the benefits of it are for a few weeks or so. I still haven't been completely persuaded to give it a try yet, and your cautions align greatly with my intentions to not bother trying it, at least for a while, whilst I'm still learning One more question, could you explain why war-birds, perhaps Spits in particular are more prone to tip-stalls? I think I've experienced it on the Phoenix flight sim so know what to look out for; where the plane seems to drop a wing very easily at the point of stalling, even with no roll rate or aileron input at the time of stall. I've not experienced that with any other model on the simulation program, so am assuming it's common for this type of aircraft but not much else? Edited By Chris Anthony on 13/05/2014 23:30:33

I think I'll give the download another try in the next day or so then, cheers BEB.

Ah Paul! I must admit, I was surprised when you said you thought a 52 would be boring, even given my inexperience! In a way I'm relieved to hear that it was a misunderstanding! And thanks both, I'll be keeping an eye out for one of those engines starting now. I had another great session tonight, I'm getting nice and familiar with the plane. I'll probably up my rates after a few more sessions, then go for the engine upgrade

It seems the thread has moved on a bit over the last few hours. Without meaning to confuse things, Erf, here is the diagram showing the "menu screens" on the transmitter. These do not change, and cannot be changed. I don't know if this is what you have been referring to, when you wondered if "menu's" exist and whether they can be changed or not? So when you switch the TX on, you start at the top of this diagram, and move down from there. The diagram is taken from this link (not my property/work) - http://www.alofthobbies.com/files/Taranis_Quick_Start_Guide.pdf It's a very good user guide for operating the TX itself. All the menu's listed in the diagram are explained further in this document, with a detailed menu screenshot for each menu to match. For anyone thinking about getting a Taranis and wanting to know what it's like to scroll through the screen menus on the TX, this document will give a good insight.
