|Thread: Servo fitting and horns|
You only have to try it to see the difference Martin. If you have, let’s say one degree of free movement due to slop then the amount of slop that is transmitted to the surface increases the further away from the centre. Your percentages don’t tell the story. It is more important with smaller servos as the size of the gears and corresponding number of teeth on each gear will effect the amount of free play in the gear set.
No doubt the 3D machine you are talking about doesn’t use standard servos?
Inner hole on servo output for better resolution and less slop/play. You don’t want to reduce the servo movement at the transmitter unless absolutely necessary as less servo movement results in poorer accuracy and ultimately jerky movement of the control surface. Just look at the way moulded gliders are set up. The inner hole on the output arm is too far out and to use maximum servo movement very often a hole is drilled 5 or 6 mm from the centre of the arm and the clevis is ground away to clear the output shaft flange or a purpose designed clevis/connector is used.
In fairness this is taking it to the extreme but as has been said in an earlier post, inner hole on the servo output and outer on the horn and adjust until you get the movement you need but only reduce the servo travel at the Tx as a last resort.

|Thread: Guess the fault|
Wires touching somewhere intermittently with the vibration? Mice have chewed the wires, maybe?
|Thread: Launch Bungee Spec|
BARCS is probably your best point of reference for this. I don't ever remember seeing a bungee used in comps. It was all hand tow back then and 150m comes to mind.

|Thread: What's your club membership size & fees?|
Your choice but we can get some great flying weather in the autumn.
I am a member of the Long Mynd Soaring Association for £5 and a private members club where coffee is provided at £75, it is not the cost of membership that is important but the value you get from it. If you have no intention of flying between now an the end of the year, great but I have found that membership is generally not on a pro-rata basis.
|Thread: P&P charges from the USA|
Yup, I don't care, it is what it is and I take postage charges into account when I buy.
The reality is that there are many reasons why postage charges are different, some as you have eluded to but also deals that some sellers can get. It really doesn't matter to me, it is the final price that matters.
|Thread: Flair Models - a question|
In the spring I bought some ply through eBay and went to Warwick to collect. It was essentially old Flair stock from their premises. I was told they were moving out and shifting the stock but there were no tangible plans to reintroduce the kits.
There is an alternative though, DB Sport and Scale. I don’t think I would buy a Puppeteer at an inflated price when there is the new Sopwith Pup from DB. I would much rather support a venture such as DB in the hope that a home grown enterprising business might flourish.
|Thread: Laser Engines - Technical questions|
You are too modest Jon
That's great news tigerman. Lasers do not dead stick unless there is something fundamentally wrong. The only reasons I have had a Laser stop in the air are running out of fuel and a 75 carb coming adrift. Otherwise I find them very tolerant when setting up so much so that I fitted a new carb to one of my 80s (the engine fell on the floor and damaged the carb!). The engine ran and ran well with the new carb without any adjustment at all, transition was faultless but it was using a tank of fuel in half the time and a load of oil on the model, I was about half a turn too rich on the idle needle. You may well have been too lean on the idle needle, time to run a tank through the engine but don't fiddle with the settings too much.
Jon runs the new engines and they are pretty much set up perfectly, all I do is tweak the needle at full throttle to judge how lean the engine is running at with my prop and that's it.
Once set leave them alone, they don't need fiddling with from year to year let alone between flights. Mine start on the first or second attempt, they run perfectly and I don't touch them other than to admire them.
Laser have the base setting for the carb here.
|Thread: Build your own telemetry sensors.|
Haven't given up Chris, just not started yet (other than accumulating the parts needed) too many other things to do and a long holiday on the continent. Maybe when the weather deteriorates, fingers crossed.

|Thread: Local Model Shops|
It is only a specious argument because you chose to see it that way and draw irrelevancies into the equation. It seems you would expect me to earn less because the purchase you make once every so many years costs a lot and you no doubt expect a discount don't you? It is very much a case of seeing what you want to see. And it has absolutely nothing to do with ongoing costs, we are talking about the simple purchase of a product.
And no one said they were expecting a model shop to discount a discounted price.
As an example I drove 2 hours to buy a pair of walking boots from a specialist shop because I couldn't get what I wanted locally. Whalley Warm and Dry in Lancashire offered a fitting service, they don't discount like the chains but they offered a superb service, threw in cleaning materials f.o.c. and a pair of good quality socks at half price. We came away with not one but 2 pairs of boots and I will recommend them highly and will no doubt buy from them again. They engaged with both myself and other half and offered a discount in another form. The same philosophy applies to model shops and to the shop in the OP, Dave implied he was looking to spend somewhere in the order of £1,500 in the near future and this shop would have has as good a chance as any to take his money. They lost out because they didn't fulfil his needs nor his expectations.
I used to sell cars, it was a family business, are you seriously telling me you would abide by what you have stated here and come and buy a car from me at full price? Of course not, and likewise I won't pay full price and will always try to negotiate a discount. I know you're going to say it's different, but it's not. I have spent as much on models as cars in the past.
And if they had knocked a fiver off the OP may well have gone back and spent an awful lot of money with that shop since he posted the original comment in September 2018, thus reaping the reward of engaging with the customer and offering an incentive to do business with them.
|Thread: CAA CAP 1789|
Thanks Martin, I see now the document I have linked to is the permission.
This seems to suggest that flying models weighing up to 7kg over 400' is approved providing certain conditions are met in paragraph 3 and is dated 4th April 2019.
As CAP 1789 is an outline as I read it, it does not contain the detail.
To my mind for the club flyer, wether power or silent flight not much will change for practical purposes and any registration, test or modest fee is nothing more than an irritation
