Thread: The great i.c. / electric finger chopping debate

Yes, good safety advice.

I am simply making the point that there is far more complexity to setting up electric, especially scratch builds but, granted, less so with “buy and fly”. With IC all you have is an engine, fuel tank, and easier to ascertain prop sizes. Not so with electric which requires knowledge and care in matching components, plus soldering skills, plus care to avoid wiring or connection errors, burn-outs, fires etc. and a greater need for use, and correct setting, of safety features.

Eh? There is far more complexity to setting up electric? Since when?

Battery, motor speed controller and propeller.

First decide on the power required and choose the motor and battery combination. I standardise on battery sizes so only have a few. No more difficult than deciding which IC motor to choose. Look at the maximum current of the motor and make sure the speed controller is capable of handling that. Props? Electric really isn't at all fussy, a wattmeter is all that is really needed to see which prop is required.

I really don't understand the wiring and connection errors, the wiring is no more complicated than the average 9 year old handles in a science lesson. Burn outs??? Fires??? Get real. Never had either.

However, I do see many struggle with a new IC motor down at the field tinkering with them to get them running properly with fingers extremely close to the liquidiser blade. I've also seen a transmitter or two knocked when taking a model onto the field with the IC engine running.

Slightly off the specific topic but it seems to me that there are far more complexities associated with EP than IC, as these contributions would tend to confirm!

Not at all. Very simple really, arming plug for most models and arm on the field, foolproof kill switch for small foamies where an arming plug cannot be fitted.

In contrast, I never have to have my hand anywhere near the prop once it is turning.

D'ya know, the more I read about Multiplex radio, the more I like it!


The FrSky radios do a similar thing, if you change model it will not start until the throttle is set at 0, and you will get a warning. Also you can pre-set any of the switches or sliders so that it will warn you if they are not in the required start position not change to that model unless you override it or move the switches to the correct positions.

I've always used a toggle switch as first, a throttle cut on ic engines (on my Mux3030) and now I'm almost exclusively electric as a throttle disable on my Horus etc. Having read this about using a rotary control (much harder to operate inadvertently) I've just altered one model to use the 6 position rotary switch rather than the toggle. Always have voice warnings, too.

I've not only found a use for the 6 pos switch but freed up a toggle switch for something else


Use one of the foolproof toggle switch systems mentioned earlier. Safer than the 6 position switch, even if it is voice activated, because you could leave that accidentally on and not hear the voice warning if someone nearby starts a noisy IC engine. The toggle switch system requires the switch to be moved a number of times within ,say, 5 seconds, and cannot be enabled or disabled unless the throttle is off. Voice alerts should also be added. Can't accidentally switch it off in flight either.

Thread: Horus RTC battery

The Horus hadn't corrected overnight or when left on for about 20 minutes in a bedroom this morning. However left it switched on in the garden sun lounge the time & date were correct when checked after about 30 minutes.
Since the Taranis doesn't have GPS I've switched off the RTC adjust option.

I'm now wondering if selecting this option increases the drain on the RTC battery a) when there's no GPS b) when there is GPS.
If the drain is increased in b) it may be best to de-select the option once the clock has been updated.

Which Horus do you have?

Thread: Leisure or standard car battery for charging lipo's

I have been using the same car battery (from a breakers for £20), for the last five years. I keep it topped up at the field via a small solar panel. Works a treat.

Some do lat a long time. My totally neglected 12V 7Ah Yuasa sealed lead acid battery I use for the glowplug and starter is 12 years old and still fine.

Because of the Yuasa's performance I bought a Yuasa 12V 110 Ah sealed leisure battery (also totally neglected, like the small one above it's never 'maintenance' charged) about 5 year ago for on the field charging and that's still fine too. Additionally I usually have at least one Lipo on charge from my car battery while driving to the field - my car is a station wagon and has a convenient power outlet in the back. .

Until the day comes when you suffer from the same problem I had recently where the charger sensed one of the cell voltages incorrectly due to a poor connection, and the charger then started overcharging that cell. Your station wagon may then become a fire wagon.

Pete, I was guessing that's what it might be about, my car's clock also uses the time signal from the GPS. The first time I tried the Adjust RTC option on both Tx's when switched off then back on the time & date actually reverted to the low battery default T&D. I then unticked the option on both Tx's re-set the time & date & all was OK.

The Taranis doesn't have GPS but the Horus has so - tried again later this evening with the option ticked - set the correct D&T on the Taranis - it's held the setting OK.
Deliberately input wrong date & inaccurate time on the Horus - so far it hasn't corrected either but this is indoors, will see if it makes corrections tomorrow.


As far as I know it is only the X12S Horus that has the GPS, the X10 and X10S don't.

In the club I belong to in the US, it is mandatory to arm electric powered models on a special bench close to the flight line, and nowhere else.

You still have to carry a live model from the bench to the flight line though.

18/06/2020 14:59:03

Never had a problem. All my planes are electric, and most are fitted with an arming plug which doesn't get inserted until the plane is on the flight line, and is removed before leaving it.

The rest, small foamies have an almost foolproof arming switch on the transmitter which cannot be accidentally knocked on, like MattyB and Tim.

Electric can be made very safe with a bit of care.

Hmmm. Telemetry somehow lost the units in the telemetry tab. All sorted now.


Thanks Tim and Bob

Bob, yes, I make good use of the Neuron telemetry already, particularly the cumulative mAh consumed, as that's a useful guide to when it's time to land! But there is, as you say, a wealth of useful data available.


Just a quickie, when yours calls out the consumption does it say milliamphours at the end?

15/06/2020 14:59:58

2.3.9 just released.

15/06/2020 14:57:13

You need the later version to get the best out of the Neuron. There are a few minor niggles, but sooner or later you will need to upgrade and face the niggles. I'm quite happy with 2.3.7.

B&Q or Wickes sell mild steel rod, but why not use carbon fibre rod from a model shop. Much lighter and stronger.

Thread: Taranis X9D & Horus X12S version updates
13/06/2020 12:17:58

Personally, I wait a few weeks and then update to the latest, which is currently 2.3.7, its now been out some time. It works fine. Companion has to be the same version. It only takes a few minutes to update both Companion and the tx.

Although changing the name's easy in the transmitter I didn't find a way in Companion.



Easy, double click (or right click) on the line in the Inputs page of Companion to get the edit window. Then its the top box, input name:

Also, if you use a model as a template copying to create a new model it can use the same model number.

If you use Companion, it now highlights in red when any two setups have the same receiver number.

Thread: Returning after a long time away

Many micro servers are only 10-12mm wide, placed sideways would these fit?

Metal geared versions of these are every bit as good and as powerful as standard servos from 20 years ago, about a quarter of the weight, and a whole lot cheaper than specialist wing servos.

As for radios, do a lot of looking before buying, lots of choice out there, with all sorts of facilities you would not have though possible years ago.

Show a screen shot of your inputs page.

Just check you haven't anything in the mixer which overrides the inputs settings.
