Thread: How does a BMFA Country Member get an A Certificate?

Film Buff, as you don't have access to an examiner or instructor you might benefit from watching this video as a guide to what's expected/involved in the test.

You'll need to be familiar with the mandatory questions as well as the handbook and CAP 658 so if you're just turning up on the day to do the test, make sure you're prepared for them - the examiner won't be trying to catch you out - just to make sure you have a working knowledge of the contents.

Thanks Martin. Without wanting to grandstand - I can fly the A and B schedule with ease. It's the logistics of the assessment that I need help with.

Hmm that's 47 miles from BMFA HQ at buckminster............

Seems like something that ought to be possible there.

That's what I'm thinking - I feel an email coming on.

Roughly where in the country are you? You may find there's someone on here who could recommend a local friendly spot!

Good point. I'm based in Northampton.

To fly at an event with any public in attendance you will almost certainly need a "B" certificate. That is the BMFA's own recommendation.

Thanks Percy. Not thinking of public displays, just fly-ins such as RCME and flying at Buckminster.

Despite 40 years flying experience - I've never got round to getting certified and these days I'm not in a club.


What's the best way to get an A Certificate (other than join a club) so I can attend fly-ins and other events?

FilmBuff - Graham has been talking to the BMFA so I've asked him to clarify. Hopefully I'll be back shortly.

Tony - Likewise. Be great to see you if you're crossing the pond of course.


Thanks David - I'll look out for the response.

I have the 2.5m Orion EV. Lovely kit and flies very well, I fitted a Hacker geared motor driving a 16" prop powered by a 3s 2200, it will climb vertically with ease and is capable of covering the sky quickly.

Thanks Andrew.

Re the blocks in the wings for the fuselage fixing. Does that mean you then have to drill them? Don't fancy that without a pillar drill...

Re your wing finish. How durable and water resistant was applying lacquer direct to the veneer? I was toying with light weight glass cloth or film.

Thanks for the info.

Being increasingly drawn to these range of gliders.

Wondering of level of work is still to be done?

I've seen old videos and build logs of people having to cut out cockpit apertures, cut foam away from the root for joiners, and sanding root and tip panels for dihedral etc. I think control surfaces are already hinged.

None of this bothers me - just curious!

I am a BMFA Country Member who has 40 years RC experience - but no formal A Certificate.

It appears that the BMFA Centre does not stipulate an A Cert is required to fly there. You can guess my next question...

The RCME event stipulates I need an A Cert to fly. I'd love to come along and take part - is there anyway this could be accommodated? Would someone be willing to stand next to me while I fly?

Just wondering... laugh

Anything can be done, but when technology fails and you are running a company single handed a bit of understanding wouldn't go amiss.

Agreed. I'm all for that. I know first-hand the stresses of being a one woman band.

My view is that small specialist retail and good comms / customer service are not mutually exclusive.

To survive, model retailers need to be able to do both.

That's a bit too black and white.

Having read the comments above from the 2 retailers shouldn't a degree of tolerance be given to the smaller retaliers?

Digital tools should make things easier. Notifications can be picked up on your phone and answered immediately. My wife makes bespoke jewellery and sells via Etsy and supplying galleries.

She makes, markets, sells and despatches everything and prides herself on her speedy response to all queries at all times.

It can be done.

I have found that on some ESC's the brake function doesn't work unless you have the throttle trim on the Tx reduced to almost nothing.

I suspect that with the throttle trim 'centred' (which is the normal default setting) the ESC will assume that the throttle is still slightly open (even though the motor isn't actually turning) and, therefore, will not engage the brake function.

YEP speed controllers seem more likely to exhibit this issue but I am pretty sure the same principle will apply to other makes. This fix has cured an apparently non-operative brake on three of my models (two gliders and one flying wing).

Certainly worth a try...……...takes a few seconds and costs nothing!

John, when you say throttle trim reduced to nothing - do you mean pulled all the way back? ie use the maximum allowable trim?

@ FilmBuff,

Hello, please look at this link


They have spinners, centerpieces and rubber rings for foldingprops.

the site is in german and englisch.

Good spot. They are on holiday until 4th July. Postage for 6 euros of rubber is 12 euros. Ouch!

@Simon It's not quite as fierce as that.

I'll double check the programming,

I'm a bit wary to rotate by hand as there is 650 Watts available... frown

Do you have a programming card or are you setting by the beep method? I think there's a possibility that some Dymond ESCs only provide braking off/medium by the latter and you need a programing card to set hard braking.

Hi Martin - I have a card and I will double check.

02/06/2019 10:58:23

@JulianJ that looks interesting - I'll investigate

Took the Vegas out again this morning. On the ground, motor does brake and the blades fold okay.

In flight, I can hear the motor braking, but the large prop still freewheels say 50% of the time.

I can live with it by climbing vertically, slamming the throttle shut and the plane does a flop over loop which always seems to folds the prop. It's then in a good position to start the dive towards earth that provides energy for fun and games aeros with the speed.

Maybe the Dymond ESC is just not providing enough brake.

Trying another 60A ESC if you have one, is where I would start. If it really is working on the ground, it should stop the prop windmilling in the air. Do you have a programming card for the Dymond ESC? Use that to check that 'Brake on' really is selected. Good luck.

Yes Piers, I have used a programming card - but no harm in checking again!

31/05/2019 11:34:56

Thanks for the replies guys. The prob hub pivot with the blades is very free.

When on the ground - the ESC brake does appear to work okay. It stops the motor well. In the air, it seems the big prop still has the latent power to rotate the motor.

Using a Dymond 60A ESC.

Reading some forums - they suggest extending the end rate on low throttle - I'll give that a try.
