|Thread: BMFA kick backs/discounts for clubs|
BMFA advising on the eligibility for a very useful grant at a time when membership numbers are down due to Covid. Another useful service provided by the BMFA, though I'm not sure that everyone is listening Andy.
I can confirm that if your club is registered for business rates, you are entitled to a £10k grant. Our club gets 100% business rates rebate thus effectively paying no rates but we still got it, though not automatically. We needed to apply for it via our local council's website. Literally a 10 minute job, filling an on-line form in and the council paid up within a couple of weeks. No questions asked.
|Thread: Where have my Watts gone?|
It sounds like you already know this but ....
Calibration usually involves powering up Tx and then Rx with throttle at max. Wait for first set of beeps then reduce throttle to minimum. It should beep to acknowledge this. Then power TX and RX down and power back up as normal.
HERE's a link to a generic ESC manual from Hobbyking Red Brick 70A files. Not easy to follow but confirms the process I've described above.
You say that you have re-set the ESC. Do you mean calibrated it? If not, try calibrating it.
|Thread: Petrol or Glow?|
Edited By Gary Manuel on 17/09/2020 19:04:41
One factor that hasn't been mentioned yet is the ease of cleaning the model after use. Glow fuel leaves an oily sticky residue which can be quite difficult to completely remove. Petrol fuel leaves only soot, which can be easily removed using petrol on a rag - i.e. no need to carry special cleaning fluids.
I've only recently heard of Pro-Synth fuel from a couple of very satisfied users at our field. I was considering buying some the next time I need fuel. Your comments have got me questioning it's suitability though. I run exclusively Saito 4 stroke glow engines - an 82 and a 150. Other engines are all petrol.
Could you please clarify what exactly is the problem with Pro-Synth fuel that makes it so bad that it invalidates Laser Engine warranties? Is it a problem with something specific to Laser engines or is it bad for all engines?

Spot on Keith.
Common sense is all that's needed. Learning how to identify the irresponsible ones and giving them an extra wide berth will make all the difference.
|Thread: Sign of the times - funnies|
An Obituary printed in the London Times.......Brilliant!!
Today we mourn the passing of a beloved old friend, Common Sense, who has been with us for many years.
No one knows for sure how old he was, since his birth records were long ago lost in bureaucratic red tape. He will be remembered as having cultivated such valuable lessons as:
- Knowing when to come in out of the rain;
Common Sense lived by simple, sound financial policies (don't spend more than you can earn) and reliable strategies (adults, not children, are in charge).
His health began to deteriorate rapidly when well-intentioned but overbearing regulations were set in place. Reports of a 6-year-old boy charged with sexual harassment for kissing a classmate; teens suspended from school for using mouthwash after lunch; and a teacher fired for reprimanding an unruly student, only worsened his condition.
Common Sense lost ground when parents attacked teachers for doing the job that they themselves had failed to do in disciplining their unruly children.
It declined even further when schools were required to get parental consent to administer sun lotion or an aspirin to a student; but could not inform parents when a student became pregnant and wanted to have an abortion.
Common Sense lost the will to live as the churches became businesses; and criminals received better treatment than their victims.
Common Sense took a beating when you couldn't defend yourself from a burglar in your own home and the burglar could sue you for assault.
Common Sense finally gave up the will to live, after a woman failed to realize that a steaming cup of coffee was hot. She spilled a little in her lap, and was promptly awarded a huge settlement.
Common Sense was preceded in death,
He is survived by his 5 stepchildren;
Not many attended his funeral because so few realized he was gone. If you still remember him, pass this on. If not, join the majority and do nothing.

I'd be interested in a closer look at the undercarriage Stu.
|Thread: What exactly does expo percent mean?|
Enjoyed getting the old brain cells working again.
I'm done now.
Just for completeness, here's what the OpenTX (red) and Futaba (green) formulae look like when plotted in an excel spreadsheet. Note that x^3 and x^4 are just labels for the two curves and not the full formulae, which are y=e*x^3+(1-e)*x and y=e*x^4+(1-e)*x respectively. In summary, the Futaba gives a slightly wider soft area in the central portion of the stick, with a more severe climb towards maximum limit than the OpenTX system (and JR despite the incorrect formula would be my guess).
Edited By Gary Manuel on 01/09/2020 23:58:38
It helps to complete the picture. My earlier post gave the formula for OpenTX (fact) and Futaba (assumed). This link gives a formula for JR (assumed) as:
Y = (Exp/10)E-05X^3 + (1 - Exp/100)X
Exp = expo expressed as a percentage
E = exponential constant - 2.718
This can be converted to the same format as OpenTX and Futaba as follows:
our expo "e" is a "per unit" value, rather than per cent = Exp/100, therefore,
Y = (e*10) * (2.718-0.5) * x^3 + (1-e) * x
Y = 22.18e * x^3 + (1-e) * x
The second part of the formula [(1-e) * x] is identical to the other two formulae. It is predominately this first part of the formula which describes the curve around the centre point, so the earlier discussion about the relationship between the expo value and the slope around the centre point still apply. The first part of the equation [22.18e*x^3] describes the curve as it progresses from the initial slope towards the maximum value. JR and OpenTX are cubic (x^3) polynomial whereas Futaba is quartic (x^4) polynomial. This difference will have minimal effect on the feel of the sticks.
To all intents and purposes, we can assume that the expo value of all three brands have the same meaning (ignoring the +ve / -ve value difference).
Edit - actually, looking at the JR formula from the link it doesn't look right! The value of the first part should never exceed unity, but it does. Not convinced that BEB's formula is correct.

The way I understand it from the formulae above, if you extend the line of the curve from around the centre point as shown in RED below, the value of expo is the amount that the throw is reduced from the maximum value of Y. In this case the expo is about 80%. I've learnt something today and it all makes sense now.
If it's an actual formula you are looking for, the following info from a google search might be of interest:
With 20% of exponential, the resulting curve will have 80% of the slope at the center of control, i.e., it would now feel like 80% of throw when the stick is near the center. As the stick moves to the edge, the slop deepens, and you still get the full throw.
Note in both cases, the slope at x=0 is (1-e).

|Thread: DVLA scam|
If in doubt about a caller / emailer, take them through security as they would if you rang them. Ask them a few questions about yourself. If they don't even know your name and address, they have no business calling you.

No a record is a flat disc made out of vinyl. Also from the 80's and still going strong today.
|Thread: Your Hacked charger PSU's.|
Never thought of that. My mistake. Definitely don't do this unless you know what you are doing!
Just use two 12v supplies with the outputs in series to give 24v (i.e red of one supply connected to black of the other).

|Thread: Covid 19 sports club grants.|
The way I see it is that most clubs will see a dramatic fall-off in the number of members due to the virus this year and perhaps in future years too. Our numbers certainly appear to be down this year. The grass still needs cutting. The rent still needs paying. A little help from the council won't go amiss. £10,000 does appear to be a large amount of money, but I assume that the £10,000 minimum grant is to save on bureaucracy of smaller claims.
The government have recently introduced model registration and other flying restrictions which have had a negative affect on membership and a cost to modellers. Electronic model tracking is a future likelihood. Maybe the grant will allow annual membership fees to be held lower than they would otherwise be and perhaps help keep clubs viable.
Leisure pastimes are important in these troubles times. The Government recognise this fact and are therefore trying to help to keep them going. I don't think anyone should feel guilty in claiming a council grant if it helps to keep a local leisure facility operating.
Does not being able to fly count as "adversely affected"?
