Thread: Is the hobby dying/dead

The BMFA sample constitution is a good starting point for a club or special interest group to form a constitution that is robust, however you are allowed to menu pick what is appropriate.

I understand. I was simply pointing out that the BMFA like to have their cake and eat it. They say different things in different documents.

I think you will find the constitution is aimed to also cover legal crap that happens within clubs, the BMFA get a couple of cases a week where someone feels agreeved at how their club is treating them and bitch to the BMFA about it.

I think that the BMFA should require certain standards of affiliated clubs when it comes to how they treat their members and clubs that do not meet these standards should be disaffiliated.

Thread: AS3X Programming

I don't use AS3X, but my understanding is that for the more advanced AS3X receivers, you will be looking at the SPMA3065 cable and Spektrum's PC software.

In fairness, you've quoted from an example constitution which is prefaced by advice that they don't expect all of it to be appropriate to every club.

The BMFA say that their example constitution is best practice.

As I know that many - and probably a majority - of clubs have specified the A certificate as a minimum qualification to fly unsupervised, this is surely an example of a paragraph that can be removed should it not apply.

If a club is requiring 'A' certs to fly unsupervised then they will not be removing that clause if they use the example constitution.

If you give small time politicians a little bit of power they abuse it, like you say the 'A' cert has never been intended as a license.

The BMFA say various things on the subject. On one hand they say that

"It is important to appreciate that the scheme is not primarily about permitting or licensing. Fundamentally, the scheme is all about personal goals and challenges. It is entirely voluntary and intended to provide every RC flyer with something to aspire to and aim for, should they so wish. The scheme is not compulsory and BMFA insurance is NOT conditional on holding any of the achievements !" (Achievement Scheme Handbook)

and on the other hand they also say that

"All flying members must attain the minimum standards of flying required under the club name training scheme before receiving the BMFA ‘A’ Certificate and before being permitted to fly indirectly supervised."

"Any pilot not holding their solo qualification for the type of aircraft they are flying must not fly without the supervision of an instructor or their specially appointed deputy if the instructors are absent from the field. "

(Example constitution)

Thread: The Gov't, CAA, BMFA & UAV legislation thread
25/06/2020 10:38:45

The BMFA have noticed that ORS4 1331 (the ANO article 94F exemption) was replaced by 1395 on Monday.

".. bring it in to line with the hoped for introduction of the new European UAS Regulations ..."

Don't forget there are currently 36k members and 780 clubs in the BMFA.

The BMFA's budget for this year is based on 31k members. This means that only around 1/3 of the 100+k SUA operators registered with the CAA are members of one of the traditional associations. It would appear that plenty of people are flying, they just aren't doing it in the way that the OP thinks that they should.

I've never seen this done on any other forum.

I have. In fact I have done it on another forum when I decided that it was an unpleasant cliquey dump that I didn't want to be associated with.

What e need is Manny to come up with some personal injury insurance claim numbers for IC and Elec? Ok they won't give the whole picture as % of users won't be known.

Only serious cases are going to become insurance claims. What it would needed is for all first aid cases to be reported to the BMFA and I very much doubt if that is either practical or desirable.

As an additional safety feature, my Tx will not transmit until certain controls and switches (throttle, throttle lock, gear, etc.) have been put into pre-configured positions (user configurable).

The same is true of my Spektrum DX9.

But nothing is foolproof given a sufficiently talented fool.

if you turn on your rx first by installing a battery in a model equipped with an ESC and BEC the receiver is live as is the ESC and the Tx is not transmitting so it is possible for spurios signals to reach the rx.

No it isn't.

Not many systems have this capability, AFAIK only Spektrum and FrSky offer this "modelmatch" feature.

If your Tx and rx are on and bound the receiver is looking at your tx signal and is "locked on to your Tx" if your rx is on and your tx is not there is a higher risk of some spurious signal being picked up by the rx.

As far as I am aware, all 2.4MHz have some system for binding the receiver to the transmitter. ModelMatch binds the receiver to a particular model in the transmitter.

Best practise is to ensure your failsafe is set to motor off and to have an "arming" switch on the Tx and use it to prevent throttle opening until you are ready to fly.

Which is what I do at the moment, but I am coming to the conclusion that for some of my models, it is better to leave the transmitter off until after the battery is connected and I am well away from the prop.

Thread: 4.8v Futaba Servos

If using Spektrum, have a 6v battery, wouldn't use a 4 cell battery on that.

The great Spekkie brownout myth goes on.

my dilemma is whether to go for 4.8 battery packs or go bigger and fit a inline regulator to the receiver

The question is whether or not you want battery redundancy. I you do, fit something like a Jeti MAX BEC 2 and a pair of LiPo packs. If you don't, fit a 4.8V subC and decent switch.

On my old Spectrum DX7 there is no kill switch unless in helicopter mode.

I am pretty sure that you can program one using a mix or two.

On the DX9, the rotary switch is marked “R-KNOB”. Switch G is a 3-position toggle switch.

You are quite right. For some reason I have spent the last five years thinking of the knob as being G, but it is isn't. How strange.

Posted by Keith Miles 2 on 18/06/2020 14:51:06:

My simple “safety device” on my DX9 is a rubber band between switches H (throttle cut/hold) and G providing just enough tension to keep switch H in safe mode until I’m ready to go.

I use G (a rotary control) as the safety switch with voice alerts.

IC engines don't generally jump into life without any warning!

I have never seen an electric motor start spontaneously.

But just because you haven't seen it doesn't mean it can't happen.

Indeed, but it does mean that it is a low probability event.

why that would cause anyone to write "YAWN" I can't imagine

Some of us who don't use OpenTx find the fact that some OpenTx users feel the need to ram their radio choice down our throats at every opportunity boring.

I have never seen an electric motor start spontaneously. They only seem to start spinning when a control is moved on a transmitter. In fact, if you are using a system were the receiver is bound to a particular transmitter, there is a pretty good argument that the safest thing is to have your transmitter turned off until just before takeoff.

I was going to say the Calmato Sport, but he wants foam.

There are some suitable post A models in the Sebart 30e range, but they are not foam.

I generally use 248 when I feel the need to secure a thread on a model.
