+/- 2.5%, not bad when you consider all the manufacturing, calibration and process variables.
|Thread: Lil Cub|
It will be next on my building bench, which will be clear in about a week. A kit from Sarik would help in getting it in the air a little sooner.
|Thread: CAA registration consulation|
David and Percy, I agree with what you say, but it does not change the inept way in which Regulation has come about.
I shall, like many others here I suspect, when the time comes register and pay my dues. I would like to think that we shall see more prosecutions for the unregistered or illegal use of drones as a consequence. I have my doubts though.
I still find a degree of confusion in the terminology used in the Consultation document and response form. In responding to the Consultation we are asked to choose from a list where our interests lie, this acknowledges a differentiation between drones and model aircraft. The next question asks if we own a drone, Yes or No? Are they now including model aircraft or not?
From the Consultation document -
There will be no charge for remote pilots to take the required test, thereby, encouraging remote pilots to educate themselves (our research has shown that 85% of remote pilots are also drone operators);
If drones includes model aircraft what are the other 15% piloting? Or do 85% of model aircraft pilots really pilot multirotor drones?
This whole process is a farce where related to flying model aeroplanes, helicopters and multi rotor devices as a hobby/pastime. The irresponsible, unwitting or deliberate misuse of "Drones" has brought about this situation and deserves control, but not at a cost to the majority of responsible, law abiding model aircraft flyers.
The previous provisions of the ANO and CAPs relating to remote operated model aircraft and multirotor drones were, if followed, adequate to assure safety. They were never effectively policed or enforced and there is no indication that the new Regulations will be, so how have we progressed?
Regulation of commercial Drone operations is a different matter.
|Thread: Variable resistors|
Reliable low voltage DC, high current switches are almost as rare as the potentiometers.
I would ask how often do you need to adjust the current?
Chris' suggestion looks worth a try and would work with a 1 or 2s Lipo, 6 or 12V lead acid gel battery as well. There are quite a few others in the links below Chris' suggestion in that large River place.
But, as peter suggests the NiMh solution is the simplest and based on my use of NiMh glow sticks is as simple and reliable as it gets.

Forget variable resistors, unless you can find a 1 ohm 10 watt wirewound, a rare and expensive item. The paralleled resistor idea will not really work with the value of variable resistor you have.
You need fractional ohm resistors. For instance if your Cyclon is fully charged at 2.2V and the plug is rated at 1.5 volts 2 amps the resistance needed is (using V=IR, R=V/I) .7V/2 = 0.35ohms at 3 amps it would be .7/3 = 0.23 ohms. As the cyclon discharges at 1.9 volts, say 0.4/2 = 0.2 ohms.
Best answer is is to get four 0.1 ohm 2 or 3 Watt resistors, five banana plug sockets and wire the resistors from one socket to the next with supply from the cyclon at one end, you then have 0, 0.1, 0.2, 0.3 and 0.4 ohms available depending on which socket you use. No switches, just simple and reliable.
|Thread: Prostate Cancer|
Sorry to hear that. The positive thing is that you have been diagnosed.
I can only repeat the information given to me and can offer no advice except for people to get checked out at the first signs of anything untoward.
The Oncologist I saw explained that in my case the hormone treatment would have been carried out first for a period of 4-6 months, then radiation treatment every day for 4-6 weeks, then further hormone therapy for up to 9 months.
I felt that for me surgery was less disruptive.
It is well worth looking through the MacMillan Leaflets explaining the surgery and radiation procedures and their respective benefits and downsides.
Just a year since I was diagnosed with stage 2/3 Prostate Cancer. I had had regular "finger" examinations, up to about 3 years ago as I had for some time had a need to get up during the night for a pee. Findings were only of a slightly enlarged Prostate, no need to worry. Need to get up during the night increased to 2 sometimes 3 times, mentioned this to doctor, PSA test followed immediately which showed significantly raised PSA levels. Immediate referral to Urology department at Churchill Hospital Oxford. MRI and Multipoint biopsy followed quickly, then offered either surgery or radiotherapy plus hormone treatment. I chose surgery, 4.5 hour keyhole surgery, home next day a few weeks recuperation and almost back to normal. 8 Weeks from referral to Surgery, can't praise the Churchill team enough, they were brilliant.
A year on and all is clear.
If you're over 50 PSA tests are available on demand, so if in doubt get tested, it's only a simple blood test and might avoid the consequences of Prostate Cancer.

|Thread: Programming AR636A|
Hi Mike, I think you may have to persevere with registering the receiver. I have several AR636 Rxs and had to download a new sprmx file for each one as the files appear to be locked to one serial number.

I gave up on cheap clamps, as you have found they fly apart. I now use those from Wilkinson hardware stores, they come in 3 sizes and work well.
Old fashioned "Bulldog" and spring type paper clips are also very useful, almost too many sizes to choose from.

I can only think that the differentiation between private and account customers is only to identify a bona fide sender.
Not the first time I've seen LiPoly batteries incorrectly described.
Whether it's a deliberate act to circumvent the postal regulations I cannot comment, however under Parcelforce and Royal Mail Ts & Cs the carriage of any new Lithium batteries not connected or part of an electronic device is not allowed
Extract from Ts & Cs on Parcelforce website on what may be sent:
I use a method that was described in an early 80s issue of Radio Modeller which has proven to make strong and reliable laminated sections ever since.
The joint surfaces of the parts to be laminated are brushed with a thin coat 70/30 PVA/water mix and allowed to dry thoroughly. When dry bring the parts together in their final position and apply a domestic iron preheated to "cotton heat" for a minute or so. As the PVA is heat sensitive it will form an excellent bond and the iron being flat will hold the lamination flat.
I have some models that have used this laminating method for fuselage formers that date from the 80s which are still structurally sound. I have even used this method with thin ply sheet place of fibreglass bandages for wing joining, far neater and stronger.

why not just use a carbon fibre fishing pole with a cord loop attached to the end, probably cheaper.

|Thread: BMFA mag's going a bit over the top?|
Well said, I wholeheartedly agree. Praise where praise is due
I see that the magazine is already available online, but not the December issue yet. It's under the BMFA tab as BMFA News Magazine.
|Thread: Home Insurance|
Damn, I stand corrected. I should have known to thoroughly read ALL the document.
I wonder how other model engineers, say those who build steam locos, do for insurance?
Perhaps it could be an add-on to the BMFA or LMA Insurances?
I suppose that from an Insurance Assessors pint of view establishing the cause of loss or damage would be a consideration, fire or theft should be straightforward, but accidental damage might prove contentious.
