Thread: Servo fitting and horns
19/10/2019 09:27:47

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?
29/09/2019 21:07:21
Posted by Christopher Morris 2 on 29/09/2019 14:39:31:

I am about to join the Kings Lynn club "but not till January when their year starts" & with the slight increase they expect to be £55-£60 next year with a membership of around 60 "but not confirmed" Plus you have to join the BMFA for the insurance.
Its interesting to see the price variations & size of the clubs that are around. Would be nice if clubs would let you join at any time & not on the 1st of January just after the Xmas expense. There are very inexpensive ways to track memberships these days either online or with a computer.

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
29/09/2019 21:00:12
Posted by Christopher Morris 2 on 29/09/2019 09:25:04:

Do Americans get charge the same fee's as us Brits on an ebay sale?. Now, many Brits were trying it on & trying to sell “!let's say a £5 item” for 1p & £7.50 P&P. So the seller only paid a commission on 1p. Now ebay stopped this & now charges a commission on the sale price & p&p added together.
Do the Americans still have the old system, or does the USA just charge a lot for P&P, as i see many items for sale at “lets say” a $50 & a further $50 P&P. Must be some of the highest P&P prices in the world as I can send to Australia for half that price. Any thoughts?

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
24/09/2019 13:12:16

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
17/09/2019 16:32:40
Posted by Jon - Laser Engines on 17/09/2019 16:08:32:

I always recommend messing with the setting as there is no way i can set it right from the factory to suit every model.

You are too modest Jon wink

17/09/2019 08:56:13

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

Sorry, but that is a specious argument in all respects. A large single purchase like a car can not be compared with small ongoing purchases like propellers. The capital expenditure is totally different, as are costs for insurance, road licence fund, fuel etc.

Model shops are already discounting heavily. My LMS generally has to take off 10-12% to compete with all the other outlets across all forms of modelling to stay competitive. Why should they then take more money off on the offchance that a customer (who has said he lives an hours drive away) may come back? And how would they police it? Do they take your details for a loyalty card? A photo? GDPR costs money as well. How often do you get the discount? On what items? On model plane parts? An entire plane? A railway set?

There is no reward to be reaped because modellers are generally a tight bunch and will always look around for pennies off. I do it, don't tell me nobody here does the same.

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.

If any modeller wants to support their LMS... Pay what the LMS asks you to pay. The people who run these shops are already being undercut by web-based business that don't have the overheads of a physical shop, they have to deal with distributers who can't/won't get the kit into the country, what they don't need is people demanding a discount just for the privilege of having you in the shop.

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
25/06/2019 12:32:09

Thanks Martin, I see now the document I have linked to is the permission.

25/06/2019 11:07:49

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

It's a Bridson Jig. I thought there was more information on it on SSUK but can't seem to find it.
