Thread: RCM&E Fly-In 2019 - general chatter
20/06/2019 12:48:47

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

**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.

@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.

Really enjoying my Staufenbiel Vegas glider at the moment - but for small niggle.

Despite quite fierce ESC braking, the 14 inch prop does not readily fold. I often have to pull a big half loop to get it to fold, or practically stall it into wind, which slows the model and hence the prop, until it folds.

Any ideas? I don't want to go down the route of trying to use small rubber bands around the hub and spinner. It's not a big problem and I'm sure I can live with it.

A very basic question. Do you apply the rudder first in the direction of the turn and then the aileorons or first bank and then apply rudder in opposite direction to keep the nose level?

It's not a good idea when your learning or flying properly to do this. However, it can be fun to do with experience. I try and emulate a control line circuit. Control the turn with rudder and use opposite ailerons to keep the wings level as the plane flies a flat circuit. Needs the right plane, and if not careful you are opening up the possibility of a spin as others have said.

On thermal gliders, when circling in lift, I find that I control the angle of the bank with ailerons and the size of the circle with rudder.  But this may just be me!

The Easter Eagle senior is really intended for light winds. The fact taht the current owner has flown it in stong winds is purely bis slightly insane choice.

He actually used to fly Mystique glider. Now he has admitted that he never knew what a real glider could be like

Reality check needed Peter wink

I did intend to take a look/test drive in another brand's electric model, but the whole 900 car UK allocation due in April has already been sold......

Yes - I wanted to test drive a Hyundai Kona or Kia e-Niro. No chance. All models going direct to customers who have ordered and paid online - not to be wasted at a dealers... 11 month waiting list and the only chance you will get to drive one is at a regional test drive day.

Here's my 2p worth.

Tesla had first mover advantage in disrupting the auto industry with stylish premium brand EVs.

But as soon as the established makers finally get their act together - Tesla will be blown away.

When EVs can do 300+ miles on a charge, cost less that £28-£30K and be recharged in 20-30 mins then the market will switch. It will be the next big mobility inflection point after the gasoline revolution of the early 20th century.

Love this Rich - the mag landed today and will be a spring build for me.

Thing is - the plan has no dimension data for the wing components.

I'm too lazy to leave my home office and run a ruler over the plan...blush

Just checked the ratings. Episode 1 got just over 1 million total views.
That's not bad at all.
That's over 960,000 non rc flyers. Surely we must act on this to get some new recruits.

No problem at all for me.
People spend hundreds or thousands on their planes. Yet some worry about this increase.
