Phoenix Model Products are showing stock of Futaba 61 SC.


Thread: Throttle Cut & Failsafe, Spectrum DX9 Black
18/03/2020 15:59:09

Disable the throttle trim (trim step = 0).

Set the throttle output to +/-100%.

Set the throttle cut to -100%.

Power up the model.

If the ESC does not arm, reduce the low throttle range until it does.

I don't get the logic of keeping the schools open either David. My guess is that they have judged that the disruption of closing them and having parents off work or grandparent looking after the kids outweighs the risk of cross infection via school.

Covid-19 is not a big risk to the under 20's so the argument for closing schools would be to protect teachers and parents.

If you close schools now, what is going to be the criteria for reopening them?

Any advice welcomed.

Before binning it, I would take it apart, check the power input wiring, clean the circuit board and give it a once over for anything obvious.

I use a iCharger 106B for LiPo and LiFe batteries and would happily recommend it.

Thread: Drone crashes are now investigated by the AAIB

The AAIB were investigating commercial SUA incidents before last July. They looked at one at Hinkley Point in mid-2017.

Thread: Has Your Club Made Any Decisions Regarding The Coronavirus?

this is flu which has always killed people.

It is not influenza. Coronaviruses are not even in the same phylum as influenza viruses.

as will mine

If you are saying that you intend to ignore all government advice regarding covid-19, then I think that you are irresponsible.

Our Club has just decided to close the field until Easter in view of the Corona virus outbreak.

What are you going to do after Easter when covid-19 rates are higher than they were when you made this decision?

Could I re-assign the redundant aileron out put (joystick) to a "switch", & use it as a flap output? Be pleased to have any thoughts.

Use Mix1 to stop the aileron stick moving the aileron channel -

AILE->AILE; point-0 = +100; point-6 = -100; SW ON

Use Mix2 to have something else move the aileron channel -

LLVR->AILE; point-0 = -100; point-6 = +100; SW ON

Thread: UK leaving EASA!

EASA "Easy Access Rules for Unmanned Aircraft Systems" document

EASA appear to have merged the two regulations and the two guidance/means of compliance documents that were issued last year into one document. I've had a quick scan through it and it doesn't seem to include anything new.

08/03/2020 21:49:43

I don't understand why it appears to be a surprise to some people that the UK will cease to be an EASA member at the end of the year.

EASA is an EU agency. EASA members are members of the EU or EFTA. The UK has left the EU and isn't a member of EFTA. Barnier's TF50 published a document over two years ago that said that the UK would leave EASA at the end of the transition period.

I will assume therefore, that the UK Government will dictate the outcome of those agreements.

The EU and UK will negotiate the agreements. See the published negotiating documents from the UK and EU.

Aviation safety. The clue is in the name .

EASA tells you what happens next. Agree, or don't fly.

Not true. EASA doesn't negotiate aviation transport agreements and all (most?) European countries are signatories of a treaty, the name of which I can't be bothered to look up, covering overflights.

The UK and the EU27 will negotiation two aviation agreements this year. One covering traffic rights (ICAO freedoms), ownership etc and one covering aviation safety.

UK is pulling out of EASA.

There is already a topic on this.

I doubt if it will have any significant effect on the regulation of SUA aircraft in the UK.

It's been odds on that we were leaving EASA for ages.

Thread: Individual cell voltage of LiPo flight battery.

mAh tells you what you have taken out of the pack.

Pack voltage is a function of many things and, IMHO, is best used to detect problems.

Assuming the Lemon Rxs use the same telemetry interface as Spektrum Rxs the SM Modlbau Unilog can measure cell voltages on upto a 6s battery, but it's probably an expensive way to do what you want

I don't believe that that the Lemons have the Xbus (I2C) port that Spektrum use.

I thought about making a protocol convertor for FrSky's isolated cell voltage sensor a couple of years ago, but decided that the values weren't that useful.

01/03/2020 09:15:28

I am not aware of anybody doing either a standalone telemetry sensor or a telemetry receiver that measures individual cell voltages for Spektrum.

You might be able to get the cell voltages off one of Spektrum's smart batteries using one of their new receivers, but it would be an expensive way to get some numbers that really aren't that useful.

You just download the svx file and copy it on to the SD card. You don't open it on the Mac.
