What is the voltage of the lipo right now? And do you have Immediate or Intelligent configured for cut off mode? (Just in case you didn't know, it's illegal to use 1.3GHz for airborne transmission in the UK, though I am not saying that's why your props stopped!)

I think you're missing my point. You don't have to give up the rights to your footage and you don't have to let them publish your work - just don't enter the competition! If you want a chance to win, enter.

I don't really understand the fuss about them requiring copyright of submissions. It's up to them, right? And it's up to you to us if we enter or not. Yes the footage is worth something, but so is the "prize" they give you if you win; it's up to you to decide if that trade is worth it...

Craig, with respect you're going about this all wrong. This is the kind of problem you ought to be trying to solve on a bench, unless you've got endless time and money to keep repairing the thing when you crash it! So what's the right way to sort this? To use my catch phrase, it's certainly...

Dewster, were you surprised because it wasn't what you expected? Or surprised because you don't think it should have done it? It did because for all it knew you were still in the air. If it doesn't know you're on the ground it doesn't have much choice but to execute RTH/Fail safe when you tell...

You have to do BNUC-S, at the moment. I tried talking to the CAA about short-circuiting the process as a qualified PPL/IR, but they were having none of it, mostly because of the practical part of the certificate and the ops manual requirement. Therefore I think it likely that your CPL and IR...

There are three big questions you need to ask yourself to be able to know whether it's legal. 1. Are you doing it commercially? (I realise you're not, as already stated). 2. Is your craft, with batteries, over 7Kg? 3. Does it have a camera that takes photos (not just for FPV)? If the...

It's a shame that you didn't feel the temperature of each of the motors and ESCs immediately on landing - it would have been valuable information if one was different to the others. Have you bench tested it since this event? Find anything? Chances are you've got a bad ESC or bad motor or more...

The letter of the law in the UK is that you can fly a small craft anywhere you have permission to do so from the land owner, provided you don't charge anyone for doing so and provided you don't have a camera on board (unless the camera is for FPV). Quite how far you take the permission thing is...

20' wide will be ok soon, if it's not already. It's just that if you had something 5 times that size you'd find life easier. Try to find a field somewhere near by? I'm not intimately familiar with the KK controller but if a wind that you thought you might be able to fly in (i.e. anything less...

If you don't mind my saying so, I think you're incredibly, erm, "brave", to be flying that copter in that space with your level of experience. Now of course, bravery is entirely up to you, because mostly it comes down to money to repair the copter and repair that nice looking kitchen. However...

[/COLOR] I can't tell you if the missing O ring caused the crash. What I can say with a pretty high degree of confidence is that that varying gains between 150 and 165 did not. As I mentioned on another thread recently, gains are not about an ability to fly or not, they're about fine tuning...

With respect, I completely disagree. I have a DJI 450 quad which has varied in weight between 1 and 2.5 Kg and a big heavy hex and each have been run with Naza and WKM controllers at different times. Both fly perfectly reasonably with default gains. I have never seen a properly built MR...

I fear you're getting swept along here and getting advice from people who love multirotor kit for the sake of it; if people are answering without having a defined "mission profile", as full-sized aviators would call it, then I debate the usefulness of the answers (however knowledgable and/or...

I did, so I'd say that's not correct. midnight999 I think to get the most useful answers to your questions you need to provide more information. What do you need to lift? And what do you need to do with it? Stills? Video? And as for Nex 5n versus a 7, why do you think you might need one...

I have at least eight 14x5 Xoars. Would they do? Send me a PM.

The defaults will be fine. On a WKM controller the difference between a gain over even quite a large range, say 100 to 200 is about flight characteristics not about whether it can fly or not.

What kind of detail do you need? Political? Physical? Would OpenStreetMap zoomed to the right level do? If money is tight and you don't need a massive area it would be easy enough to join a collection of screenshots to cover the area you want.

There is a reason to keep under 7Kg, though whether it's relevant to you depends where you want to fly. Once you exceed 7Kg you need permission from the controlling air traffic control unit if you're within controlled airspace (i.e class A, C, D or E) or within an aerodrome traffic zone. In...

I upgraded the firmware in a V1 Naza and found no substantial difference in flight. The only really noticeable thing apart from different LED indications is the startup procedure, whereby the props spool up to idle speed on initiation of the sticks down and left command, but then remain at idle...
