I received a plastic bagged package from Banggood today and it smelt of disinfectant, so maybe our customs or theirs are decomtaminating parcels too - just in case!!


Thread: Spektrum DX6i Throttle issues
27/01/2020 22:41:57

Carlos, As the throttle potentiometer responded to switch cleaner my suggestion would be to dismantle your transmitter again and put a few drops only of 'genuine' 3 in 1 oil into the potentiometer. That will help stop the silvered elements within the potentiometer oxidizing again. Long term a replacement potentiometer/gimbal is the safest option as a helicopter with the blades spinning uncontrollably is not fun!!

Definately set the throttle cut to 0 as even a low throttle setting will cause lots of destruction if mother earth intervenes in your flight plans.


Thread: Stuck piston ring
20/01/2020 15:28:10

Not tried it myself but a few of the even older members at our club swear by diesel fuel (the sort you put in your car not the free flight stuff!) for freeing badly stuck piston rings. Apparently you may have to leave the piston in the stuff for a few days but it is supposed to clean the gum or oil off really well.

Might be wrth a try.


Thread: Gas engineers

We live in an all electric powered house and theoretically all the energy goes in the storage heating system but I am always confused about the amount of steam coming out of the vents of gas powered systems. Surely that steam contains heat that could be recouped via a condenser system and fed back into the system to improve its efficiency?


Thread: Soldering station.
03/06/2019 09:35:49

Its a good idea to never run these 'oriental' irons and heat guns at full output as they are only rated at 220V AC and we are (nominally) still at 240V AC, so the elements will have a very short life if over run. I set mine to 3/4 max output and they then last a reasonable time. Secret to soldering success is a clean, well tinned soldering iron bit, clean component and wire connections, and a decent rosin based flux paste to prevent oxidation.


Thread: Prostate Cancer
27/04/2019 21:57:13

I had the skin cancer on my leg removed this morning in a 45 minute fairly painless procedure, and just have to wait up to 4 weeks now to find out if it was a bad one. The most painful part was having to pay out almost £5.00 to park in the hospital car park for an hour!!

Hope all goes well for you Martian, and remember guys, if anything seems a bit odd get it checked out quickly.

I was called for my AAA test couple of years ago - and apparently I had the internal body structure of a 20 year old (pity I had to give it back!!), but trying to get a PSA test was a totally different matter. I too go for the annual well man tests at our doctors, which are carried out by a practice nurse, and they cover diabetes, blood pressure and BMI - but not PSA!!

I have to take up a doctors precious time for this test, which seems a total waste of resources, as surely the practice nurse has the required skill to take a blood sample.

Now a small spot of what was dry skin on my lilly white leg decided to erupt into an angry bright red spot a month ago, which then formed a hard crust with a red ring around its perimiter. Fortunately my well man check up was at this time, so I showed the eruption to the practice nurse who said it did not look like anything serious, but it might be prudent to have a doctor check it out.

The doctor checked it and said he did not think it was anytghing to worry about but put me on the cancer pathway with a referal to the hospital. After a wait of two weeks I now find I have skin cancer!! ,so am now awaiting an operation to remove the appendage, but during the check the consultant also found a number of dry patches on my forehead and temples, which fortunately are pre-cancerous, so a cream has been prescribed to deal with these.

As I am very light skinned I have always tried to limit my time in the sun, word indoors throughout my working life, and wear my Tilley, and factor 60 sun cream, even on cold overcast days, and never wear shorts etc, except in the gym or swimming pool. I have suffered sun burn (through my lighter clothes) on a couple of occassions, but have never had a su tan or been on a sun bed in my 68 years on this earth, provingskin damage can happen to even the most careful people.

Oh the joys of getting old!!

Hope you all have 100% success in getting your tests and subsequent treatments.

Just read that Mr T has grounded all 737 8's and 9's in the USA.


Thread: Align Trex 250 micro heli spares

Hi Robin,

If no one else comes forward I would be more than happy to take those off your hands, as I have a couple of Trex 250's in regulary use. Would need them posting though but happy to pay postage etc.


Thread: LED Bulbs pt3
25/02/2019 17:07:19

Just a quick observation Denis, if he only uses one series current limiting resistor then would need all of the LED's on to calculate its value from (Voltage to be dropped/ total LED current), but if only a couple are then turned on, the resistor value would need to be different. I suspect like you that the control unit already has the current limiting resistors for each LED built in


Thread: LED Bulbs
18/02/2019 17:50:05

Another important point Gary is that the manufacturers normally recommend not bending the legs too close (3mm away minimum) as it can break the seal to the LED, or in the worse case the wires may snap off, as these days they are made of steel, which is not as malleable as older copper ones.


18/02/2019 17:23:16

The resistor can be fitted anywhere in the LED leads and is not polarity conscious, but do you know the value and Wattage of the resistor you need?

To work this out you would need to know the LED voltage and current. If you post the supply voltage and the LED ratings on here, I am sure some kind person will calculate the resistor value and Wattage rating for you.


Thread: Higher Quality Heat Shrink
03/02/2019 09:21:10


The adhesive lined heatshrink is the one I use for motor/esc and battery connections as it is the rubbery type, and although slightly thicker once shrunk, the internal glue gives extra protection, and provides a watertight seal around the joint as well.

Have a look at E Bay, item number 122976395367 which is for two 1 Hz flasher IC's which need no external components and all for £2.09 inc p&p.


Thread: my dremel drill
05/12/2018 09:42:37

Electrolube switch cleaner should remove the oxidation but then it is a good idea to smear the contacts to prevent future oxidation with vaseline or (genuine) 3:1 oil, as it has an oxidation inhibitor . The switch contacts are on a printed circuit board and I once tried to repair a JR transmitter that had WD40 sprayed into it but it had penetrated into the circuit board and made it conductive, so the transmitter was a write off.

If all this fails a new switch is the only option.


Thread: ESC to Battery Wire Length
12/10/2018 12:03:51

When the existing ESC cable lengths are insufficient, it is always better to extend the power input wires and keep the three motor wires as short as possible. The reasoning behind this is that extending the power input wires will, through losses in the extension cables, introduce additional resistance into the circuit, resulting in a slight reduction in the voltage and current available to the ESC but with 'reasonable' cable lengths and use of suitable cross-section extension cables, these can be made pretty insignificant.

The three motor wires provide high frequency pulses to the motor windings and extending these could lead to increased electrical noise in the aircraft and in extreme cases, the additional inter-cable capacitance and resistance caused by the extended leads can cause motor timing or other issues.

I hope this helps some but if you keep the power input wires to the ESC below 300mm you should be OK but always try to keep all of the ESC wires away from other internal wiring, to reduce the chance of introducing radiated electrical interference into the other systems within the aircraft.

Saw a new one on the Weston park swap meet for £15.00 which I thought was a bit of a cheek.

Thread: BBC Weather

I use and select the nearest golf course to the flying field and it gives you hourly forecasts of the temperature and the feels like temperature(wind chill), wind direction, average speed and gusts, cloud cover, rain fall amount and I find it much more accurate and relevant than the BBC's efforts.
