1000 apologies Mike, I am an idiot, and was using a tablet with barely a small screen visible above the onscreen keyboard, and hit send early. I was going on to say, with a basic Tx, you could get out to the field while you decided your next step. My point, with the input voltage, was that the designers had made battery fittment by the user almost foolproof by allowing such a broad range of input voltages. This too helped their sales as we all choose different chemistry to do the job. Interesting comments have been made about "voltage drop" within the circuit, but all equipment suffers this, and is the reason for voltage alarms and fully charged packs. 3S is more than fine.
-
It would seem better judgement to buy a proper TX at the outset and negate all these problems, then we can talk about flying. It was a lovely day today, though crisp
-
Having done the math, a 2s 1000mAh would keep you going a long long time, but the only battery type that you can charge safely within the TX, would be regular cells.
-
Just a note on Capacitor voltages. Those in our range are typically 16v or 25v, which will suffice. These small Capacitors discharge at 2/3 the voltage in the circuit, so are useful in this application. Get onto me if you need more info. But 1000uf is a good choice, and easily available

The Turningy 9x, has an internal 1.5 mAh regulator, to handle a 6 - 30v input, and regulates to the user battery installation. Just put a reliable cell assembly into the TX
-
HK recommend their own 3s
Lipo for this TX

The beeps told us all along that it was a TX throttle problem. Well done lads
-
A continuous note, or a broken bleep bleep are different warnings on different ESCs. 1 is a throttle stick high warning. And the other is a battery low warning. I would try again with the DX9 and reverse the throttle channel. Switch all off, and then TX 1st as normal, then connect glider battery, should be ok

Yes Simon, get in touch with the mods. There will be an answer on here when the scale modellers get on

Balsa Cabin do Lo Bounce Air Wheels in your size 40mm/2 inch, for £5 - £6.99 per pair
-
To add, with the prop at 6 Oclock position, the top tip leaned 4 mm towards the pilot
-
The picture with the prop hub showing. That hub was pointing UP on the flyer I see, about 4mm, quite a thrust line.

Do not overlook Dan, the fact that Spectrum has 1000s of followers, it could have been Futaba or Hi Tec, but Spectrum hit the market heavily. Add to that, incorrectly bound receivers, and screened aerial signal loss of 2.4 gig, all user installation faults. You then get 100 complaints and bad press. Their (Spekrums) success in numbers has led them to this position. ALL 2.4 gig, fully charged, correctly installed, is virtually bullet proof, control wise.

Download Firefox Andy, it will be clean and is a good browser

After an acceptable length of air time, showing a way to fly using the buddy, we hand the tranny to the rookie for further practice, standing beside them. During these flights, the new boy has the luxury of handing over the transmitter when the model gets away from them. On this occasion, after a number of successful circuits, the model gained speed towards the ground, and as usual my response was “ lift the nose……..throttle back……lift the nose !”. In these few seconds, the model was racing towards the ground at a high rate of knots. My prodigy promptly turn towards me and thrust the tranny into me……………up……side……down…………….THUD ! ! !

ERM, but if you are messing about with loose leads, connected to an incendiary device, in your house with your wife and children nearby, please don't become another erm…… der……. Statistic

Hi Dan, you will be inundated with good advice shortly, but just to move you on, give that motor a good soak in WD 40 or petrol, just in case it is OK. Turn it over gently by hand in a day or two, after squirting clean oil into any openings. Also, your servos should be fine as connectors are just the same, but they are relatively inexpensive to replace. You will find 2.4 gig easier to install, due to small size, but observe the instructions for aerial installation, and vibration insulation. Welcome.

Catastrophic if you put the wrong bullet plug in the wrong hole, DONT risk it
-
I just thought that a 46 would allow you to fly the model using the throttle stick fully, rather than at half stick with the 91 flying it like a rip rap. Put the 91 on a Wot 4XL

Clear your cashe Andy, and retype your log in freshi
-
To keep your options open John, as you may have IC equipment to hand, look up the ARTF, Seagull Jumper, and the Boomerang that can be prepared in a day or two.

1st don't, Don't try to run the motor with the ignition lead disconnected from the plug, and no disrespect, but it is quite common for users to try to start with the motor kill switch on. If you petrol, in a chamber, compress it in a spark atmosphere, it will ignite. If it does not start,, there could be no spark, no compression, too much fuel, as ignition is 9000 to 1 fuel air mix, or no fuel

Hi Steve, LOGIC electronics, as in our equipment etc, states that if you can SAY it logically, then you can do it. You do of course, just need enough channels, and assigned mix switches. Complex mixes of this kind were achieved before computer radio using ( logic gates ) Y leads and clever planning. Make a ( logic diagram ) "family tree like " diagram of your need, then go through the map with your TX

Tether the model, or take the props off. Slowly, click by click, move the throttle trim up/on. The motors should get closer to the same start. Twin motors will exhibit slight differences, due to friction, age, and lubrication. Just get them near as you can on the trim without beeping. Keep in touch
High mAh AAA pack
in Batteries and Chargers
Posted
Please don't shoot me down. I am trying to use normal language and give you all options. The AAA battery size remains the same volume for both 500 mAh, and 2000 mAh, yes? OK, so the manufacturer has to fit in their AAA an electrolyte to store 500 ma, or 4 times as much, 2000 ma. Now imagine the electrolyte is a sheet of A5 paper to be rolled up and slid into the AAA pack. How thick would the electrolyte be at 500? But more importantly, how thin would the electrolyte be at 2000?, 4 times as thin is the answer… The same goes for AA. We have a longevity issue now, as the thinner electrolyte is used up more quickly in the volatile atmosphere within the cell. Please allow me this simplistic explanation. Us AA always when you can, and as low as you can buy, e.g. 600 - 800 - 1000 mAh , as there is simply more meat in them. We all think 2000 is wonderful, " charge it once per month ", but in general a lower mA rating has heck of a lot more punch. Conclusion, with standard servos use AA, and if room is an issue, odd shaped packs can be made up
