If the club has a written statement about leaving items unattended in the area where cars are likely to drive, then it's a mix of carelessness on the part of the broken model guy and lack of attention by the driver. I'd say (with my chairman hat on) if you're leaving kit around the parking area then it's 90% your own fault. The flight line and pits exist for a reason! I don't trust other drivers on the roads, I definitely don't trust drivers to pay attention in an area they know well with lots of potential distractions.
They're both at fault and if they can't be grown ups I'd give them one warning and if they continue to cause problems I'd boot them. I've done it and it works: pour encourage les autres.

I'm no more going to tell you which ones I buy currently than give you my car or house keys, especially in these shortage limited times
What a baffling statement.

I would have thought that unless the moving air needs to be straightened/untwisted for a specific purpose (such as being further accelerated by a second fan in series) then there is no need for stator vanes. Stator vanes exist in full size gas turbines, but for specific reasons.
Co-ax props on some drones don't use stators because the air being accelerated by the first prop meets a second prop of a higher pitch and lower diameter because the accelerated air does not form a cylinder of equal diameter; because of pressure differences. It's adding weight, compexity and drag when you don't need to.
I'd say that for model aircraft stator vanes are a flawed exercise in applying full size principles in the wrong area.

It seems like the root cause of your problems are the propellers, and I really don't understand changing the 2 blade props for 3 blade, unless the larger radius causes a potential tip/ground interface issue.
If you have to land wheels-up then 3 blade props are more likely to break themselves or maybe bend a motor shaft and IIRC 3 bladers are less efficient.
If this is a purely aesthetic thing, then you cant see them in flight and the sound won't be dramatically different so perhaps fly with two blade props and leave three blade for looking pretty on the ground, they're not that onerous to swap over if you need to.
FWIW... I really don't like three blade props! ?

Technically heresay. Being pedantic, but not evidence.
I have no horse in the race. I have lots of sheet balsa as I’ve always bought bulk, and bought more bulk when I run out of any thickness. Hence I have an embarrassing amount, and I cut all strip wood. Alan’s offering is also heresay, for balance. Obedience of the best evidence rules also is a bit thin, in both cases.Good point! ?

I'd say there was some sort of shortage when 4 pieces of 1" x 1/4" trailing edge cost a smidge under £14 not including postage.
Postage on anything fragile and 36" long will be painful. Addlestone models cheerfully cut some into 18" lengths for me.

My evidence is that SLEC have posted pics and videos of their machining process and that Balsa Cabin have told me that they cut their own wood when I have spoken with them at a show while buying wood.
That's good enough for me.
It seems like it's not good enough for you as it doesn't fit your pet theory.
Nowt to do with my whether or not it fits my "pet theory" (although it still makes complete sense to me, and I reckon it's a mix of the two*), I just have this outdated notion that if one makes an assertion, one should be prepared to back it up... Admittedly a Sisyphean task on this and most other forums.
*One container of wood for all distributors makes far more sense economically than everybody individually finding £12k** to ship their own stock.
**According to J Perkins via my LMS.***
***Evidence! ?

But SLEC and Balsa Cabin do get balsa lumber and saw it down into sheet, strip etc and grade it. So they are in control of the stuff at the top of the supply chain in this country and I've bought wood online from both and am always happy with their wood selection and grading.
Your evidence being? Also, according to an article in RCM&E a few years ago, IIRC, the timber is sanded down to thickness. That struck me as rather wasteful at the time, but I suppose it may make sense to the moneymen who run the companies.

EV has undoubtedly come on in leaps and bounds, and will continue to do so. Wonder if there'll be after-market sound modules to make electric sound like ic. Probably.
There already is. It only simulates certain cars and can only be fitted to certain models so I'm waiting for one that sounds like a TIE fighter.

"Is there a balsa shortage 2022?"
Define shortage. My LMS -Addlestone Models - has loads, but talking to the guys in there, they have no control over what grades actually turn up in a shipment. It seems that the suppliers take an order for x amount of y size and the shop gets what they're given.
Interestingly, some of their stock has SLEC stickers on it, so I am more convinced than ever that it all comes from the same source on the same container and is all the same stuff supplied to all stockists... So people saying (as they have in other threads) that SLEC or Balsa cabin have access to superior wood on the basis of received wisdom and no evidence can put a sock in it.
The guys in AMC will weigh it and do the drop/resonance test for you, which is good service.

The garage has already been waiting for the replacement battery from the manufacturers (who they represent) for 6 weeks with no indication of new delivery date.
Not a good representation for electric vehicles.
Specious argument. Supply chain issues are a fact of life across all industries at the moment, the fact that it's an electric vehicle makes no difference.

A new housing estate (not a big one, more of a couple of large mews plonked on a field next to a small business centre) has sprung up just down the road from me, and every single house has it's own charging device.
If volume house builders think it's the future, it's on its way.

Any one want to buy a Eflite 80mm F16 minus a front landing gear????
Split it for parts, put them on EBay or in the forums and make bank!

BTW LHF - I don't know what device you used to post your 'justification' query, but I can pretty much guarantee it was made in China...
Actually I carved it myself from a block of balsa i grew in the garden using a scalpel I forged from ore I dug up and then covered it in homespun nylon and dope, and harvested berries to create the ink for lettering the keys.
I bought the dope from my local alchemist.

I have decided to bite the bullet and buy from within the UK as we need to support the hobby in this country, i already buy all my new kits from UK manufacturers.
So you only decided to support the hobby suppliers in the UK after the price of a few items crept over what you were felt was cheap?
What was your justification for not buying beforehand?
Also a higher C rating (if such a thing is accurate on cheap lipo packs) means the battery will pump out higher currant for longer. The upshot is that you will probably have longer flights with cooler batteries delivering more cycles than your tired old batteries.
-
My word, some people really do like to over complicate things.
All my batteries live in a case, they get charged when I know I'm going flying. At the field I check each one before it goes in a model using a battery doctor. Back home they all get run through a storage cycle on my charger.
Minimal steps in the process. Simple. Easy. Fool proof.

On this thread I'm seeing a lot of "I saw somebody doing xyz" but not much "I intervened when somebody xyz."

There is a good deal more than Amazon's wish to deliver by air. There are pipeline surveys that are currently carried out by full size aircraft, there are environmental controls that could use drones with great success, there are surveys of crop health that can be carried out with greater granularity than space based sensors, there are emergency services that find drones very helpful in getting a better assessment of emergency conditions to name just a few. There is the potential for new aerospace companies to enter the market with new products that may give employment and generate tax revenues as mentioned by MattyB.
All of you who are looking at this as a purely model aircraft sport issue have missed the whole point of why governments around the world are trying to get into this market. I'm sorry, but whatever you think about what is offered by the CAA fee you miss the point. We are able to continue to operate much as we did before the whole drone business came up but we have more pressure for use of the lower airspace. Remember that if we fly aircraft that weigh up to 7.5 Kg MAUW, and we (members of the associations) are flying outside a FRA then we are allowed to fly up to the limits of our unaided natural eyesight. I consider that to have been a major coup for the model associations since that was as it was before. Yes, we do have to pay a fee since we have to register ourselves as an operator but that's a miniscule cost when taking all the costs of building, flying and driving to and from the flying field currently costs us.
On that note, I shall not be posting on this or any other discussion on the iniquity of this regulation that has been passed by Parliament. It is a complete waste of time. We are all entitled to our views on this forum - I just won't be reading them any more.
Spot on, I could not agree more. At some point, as a response to this, someone will moan that it's unfair and the drone industry should be paying for the increase, or indeed the entire registration infrastructure. Well, hobby UAVs are part of the airspace so get used to it.

Odd that 4 forumites cannot tell the difference between the roles of the Home Office and Department of Transport.
Not really. A lot of what is put in these type of threads is poorly thought out, unresearched, reactionary, knee-jerk, off-the-cuff, point-scoring, asinine and unhelpful to everyone.
I include myself in the above because I have self awareness.

I did suggest a co-ordinated mail campaign addressed to the Secretary of State. It might not produce a result, but it would remind him of our displeasure - especially as he was once so vocal in opposition to more regulation for model flyers.
But it would need pretty much the entire membership of all the modelling associations to write, and it seems that most are ready to just roll over and do as they are told.
Apathy rules, OK?

The Secretary of State is a woman, and given her record, I doubt Priti Patel would give a tinkers cuss about anything model flyers think.

Two glorious days flying on the trot. Only person at the field, no crashes, freshly fried sausage sandwiches fir breakfast and lunch.
Flew my FT Explorer with a 3s 6250 and got 20 minutes!
Glorious, I say.
I also got slightly sun burned on the neck.

The reason for my post on this thread is quite simple.
Since the revamp of the site I have noticed that there are fewer and fewer people posting on the forum.
There also seem to be far fewer people creating threads.
I have seen many familiar names disappear from the forum, who were regular contributors.
Either they are dropping off the perch at an alarming rate, or like me are fed up with others constantly moaning and using the forum just to vent their frustrations.
In this particular case it is about something that we all knew was going to happen anyway. Anybody with half an ounce of common sense knew it was inevitable.
I'm afraid this is not specific to this forum as it appears to be the way of the world these days.
Don. A friend of mine once said that people went into politics because they were poor business people (He also thought Maggie Thatcher was a bit left wing !)
Alan. I wouldn't want to denigrate anybody. far from it. If there are people who want to be involved in our hobby who have financial restrictions, maybe we should be discussing how we can help them on the forum instead of topics like this one. I for one would be all in favour, particularly at a local level.
ED. No comparison. Just stating facts and reminding people of them.
I am well aware of the actions of working men and women in the 1950's. Some of them were better than others.
I take it that you don't believe that the CAA carries out a service that is of benefit to aeromodellers ? They have their overheads increased as well.
This is my last post on this thread as I can see it ending up as the usual "slanging match"
However on a positive note I have read a comment that has piqued my interest and I will be starting a new thread on the subject, which I hope will have a more constructive response.
Mods. Please feel free to alter or delete this post.
I suspect that less people are posting comments or starting threads because the performative moaning across this site is deeply tiring. Why bother visiting for a few nuggets of useful info when you have to wade through the angry self regarding of a post-eager minority of increasingly irrelevant old men banging on about what they can't change to a willing audience of the same.

Oh what a suprise . The CAA has announced a price hike to £10pa as from 1st of April as announced in the BMFA lataest mail shot.
It should be a an April fools joke as it just beaurocracy for the sake of it .
This come just as the Chancellor announced that he intends to cut wasteful practices in the government . He could start by cutting the job of the petty minded , probably highly overpaid twonk who thought up the idea of taxing our hobby in the first place .
Response from the BMFA "One consolation is that the fee still has some way to go to reach the £16.50 proposed originally by the CAA back in 2019 which was strongly opposed by the BMFA and its members."
Sorry but thats not good enough as we gett absolutely nothing for our annual outlay to the CAA.
So what else are you going to spend that massive £1 increase on? 1/5 of a pint? 1/3 of a terrible servo? Pop it in a charity box, maybe? Or put it in a savings account and be amazed at how little interest it accrues.

Club rules. I try to keep a light touch in applying them, but when it comes to members threatening each other or putting the club's existence in jeopardy I come down like Zeus thunderbolt.
