What about marking everything up with a DNA trace and slapping stencils all over? I'm not sure how much of a deterrent to a particularly keen thief it would be as they're normally stealing to order, but perhaps enough to deter an opportunist.
An alternative, I suppose, would be some very bright lights and sirens which would go off if the doors were forced.
I have a friend who has a car garage and he has installed some smoke systems, which fill the space with thick smoke. Coupled with a strobe and a siren, I can imagine it's quite effective at stopping people wanting to hang around.
Providing you put up a notice warning thieves of the potential hazard of course. That puts the risk firmly on their shoulders should they choose to go ahead.

Cut a groove all the way round with a triangular needle file. Go round a couple of times and you'll find that you can just "snap" the tube along that line.

Thankyou everyone

So I thought this might be fun, but has anyone flown one?
I'm thinking a 4max 2847-2100 inrunner on 3S 1600, maybe a 6x4 or even a 6x6 APC prop?

Don't know if it's any help Matt, but T9 HobbySport still have a few Delta 8 receivers which work with AFHSS (as well as Futaba and FrSky). They're £24 each. I've got one I use on FrSky ACCST and it's been perfect.
That's actually a really great help, thankyou. I hadn't realised any others worked on AFHSS other than Hitec's own. I just ordered one so I'll see how it goes.

Hello all,
I'm looking for a couple of Hitec AFHSS compatible receivers. As far as I know, the Optima (9,7 or 6) and the Minima are AFHSS compatible. Ideally Optima 7, but not too fussy.
Many thanks
Matt

You can also squeegee a little mixed epoxy and microballoons into the old screw holes if they're a bit close to the new ones to get a true hole. Let that dry and drill out the new holes.

What I love about this forum is that we (I!) can be grumpy, opinionated, impatient and aggravating but not once have I ever felt any angst, malice or spite here. We are all part of the greatest hobby the world has to offer and this forum does so much to keep that community together.

I wonder what happened to all the moulds and patterns for all these things. Lost in the mists of time I suspect
Thankyou 👍

Evening chaps,
Before I give in to the inevitable explanation that I am getting old, I thought I'd try this. Years ago, I seem to remember EMP producing a GF fuselage as an alternative to the ABS one for their Aurora and possibly Apex kits. Now I might have this entirely upside down but iirc it was quite a pretty thing. I just can't find a reference to it anywhere. Did I dream this up, make a mistake or simply go mad?

As a serving Coastguard rescue officer I was first aid trained and yes been in a situation where could hear ribs breaking as team member was doing CPR. When it is a chance of life or certain death a few broken ribs is least of the problems.
If you do CPR properly its almost a given that you'll break a few ribs. I can count on one hand the times when there hasn't been some when doing it (for reference I was a St John Ambulance First Responder and now work in the nursing team in the Emergency Department at an NHS hospital)
Anyway, my apologies for the diversion. I guess what it boils down to is that I always keep a first aid kit in the car, but it is probably sensible for a club to provide one, even if training etc is left to the individual.

Yes, this is my understanding and is what I was told just 2 weeks ago on my latest first aid refresher.
I don't have any details as it was told to me "second hand" while I was doing my First Responder training. I don't know the veracity of it or the outcome in terms of court. So, whether true, exaggerated or otherwise I don't know. However, I included it because it is the sort of thing that colours people's behaviour at times.

There's always an example to find, look again and you'll find far, far, more examples of when things worked out, but less attention gets paid to those.
And no, it's not the situation I find myself in, I'll continue to get involved, the rewards outweigh the miniscule risk.
You're absolutely right and I will always do what I can. If that results in any subsequent issues then so be it but I'd always choose that over not doing anything. As long as we understand the limitations of our training and the potential risks, then doing something is always better than doing nothing.
Sadly, a lot of the world doesn't think that way anymore.

Like a lot of us I suspect, I generally just plug/unplug the Lipo from the ESC before and after flying a model.
Generally, that is reasonably straightforward but I can imagine some situations where accessibility might not be so good.
Is there a way of having a remote "switch" so that a Lipo could be connected at home safely and then "armed" at the field. I assume that a simple switch in the lead between ESC and Rx wouldn't work. So potentially an extension lead to bring the connection to a more accessible position to plug/unplug seems practical.

Not aimed at you Robin, aimed at the idea that doing things, leaves you open to being claimed against. Strange thinking from a group that sets flying clubs up, and permits people to fly, not exactly risk free is that.
Sadly, this is a situation which we find ourselves in. As an example, a recent case involved a person who wasn't trained, administering CPR to someone they thought had no pulse. Sadly, they were not in cardiac arrest and the CPR broke a rib (not actually unusual). The "victim" pursued a legal case against the person who attempted CPR. The result being that they were held to be negligent as they had no training in diagnosing or treating an arrest.
I would have done the same thing but it is the sort of thing that makes people think twice about administering first aid.
That said, I would always advocate having a first aid kit available, especially a lot of gauze, compresses and similar. I suspect lacerations, burns and twisted ankles are likely to be the most common injuries.

propeller suffers slippage and the harder the force it is trying to overcome (draggy airframe or gravity being two examples) the more slippage you get.
That's true for a model sitting still, but the amount of slip varies with airspeed. Consequently, thrust is not equal throughtout the flight, even if the throttle isn't touched. Indeed, it is perfectly possible to exceed the net pitch speed and have a resultant thrust of zero. Therefore, whilst throttle curves etc can help create a more linear throttle response, that doesn't necessarily mean that the airspeed or thrust response is also linear.
At best, the throttle curve will be right in one area of the flight envelope, so for my dumb thumbs and creaky models, I make do with wiggling my thumb around to get the response I want from the model.
-
Thankyou. That's basically what I needed to know. My assumption then, is that to get the performance I'd want from the model, I'd be looking to have more wattage (cost, weight etc) than I really need, given that I could shove a reasonable size outrunner in the snout for very little outlay and probably better performance.
That said, there are some examples around but I have no experience of them, the Max Thrust Aggressor Extreme being one of them.
I could just go for one of Stan Yeos electric jobs like the Pzazz. I just happen to really like MPs (nostalgia I guess)

Only YouTube vids but I am more interested in the warbirds especially the f4u corsair.
That's all well and good and many a beginner has said the same thing and come to regret it. There's a lot of experience on this board and it's sometimes worth listening to that. Otherwise, there's very little point in asking the question if you already know better.

There's also the smaller version of the FMS Easy Trainer. Might be a bit tricky in a wind.
Depending on skill level, perhaps a UMX Crescendo might work. You can start on 2S and move to 3S for more performance on the same model. Enough ability to keep you interested. AS3X should help in the wind to start with. Might be a bit quick (visually, small models get small very fast so appear a lot faster)

Hello all.
I'm contemplating building a Middle Phase 2 as an electric model as an alternative to foamy lot. I would normally aim for around 100w/lb for something like that, but one of my ideas is an EDF unit on top of the wing and I'm not sure if the same formula applies to EDF
My initial thought would be something like this, but on 3S rather than 4, or would it need 4S because of the higher kv motor?
But I'm not at all experienced with edf so working out power systems is a new thing.
Any thoughts? I'm not sure how things like diameter, fan pitch, nacelle length etc work in comparison to a prop.

Good suggestions, but GrayAce doesn't fly in a club environment, and it's pretty much certain those planes, with their greater inertia, will be damaged (possibly terminally) very quickly if he's going it alone. And they will need an even bigger flying site for any element of safety.
My apologies, I missed that part. In which case, I think the combination of lack of space, wind and relatively inexperienced pilot renders the question moot.
Ignoring the potential to lose the model in a tree, on a road or whatever else, it'll only take a moment of disorientation and a close call with a member of the public and there'll be a "no model flying" rule slapped on the park.
Stick to the heli and calm days, or find a more suitable place to fly when the wind is blowing is my advice.
We're on the radar as it is with all the drone incidents and the powers that be don't differentiate.

My go to for windy weather would be something like a Max Thrust Aggressor or similar. Using a powered glider may seem counter intuitive but they tend to be a bit more slippery.
Alternatively, an original (as in Chris Foss kit, not foamy) Wot 4 or similar is tough to beat and makes a decent trainer to transition.
I think the small foamy models you suggest are going to just be a frustration ultimately, and no more capable in a wind than your heli.

Just one (albeit out of stock) option, I'm sure there are many others.

In a legal sense, you are possibly correct. I'm not a lawyer so I'm happy to be corrected. However, isn't it the same ballpark as "bull in field", "beware of the dog" or "caution, fragile roof" ?
If I drive down a road clearly marked "unsuitable for motors" and damage my car, who is liable?
Ergo, a sign saying "site protected by klaxon, may cause discomfort" then who is liable?
The principle being not to cause harm but to make the place uncomfortable to stay in long enough to go through with the robbery.
But, a legal expert, I am definitely not. So, by all means elucidate
