Cool Video i wish i had thought of a PC PSU before i bought a proper transformer etc, as for the heat gun all you have to do is touch the heat shrink with the soldering iron to make it shrink, is a good idea but may be a bit big to lug around in your flight box.

any decient gas lighter will sort out the heat shrink i use the long ones that you use for gas cookers

thought to put this on for the rest sqwidge this is wot i was on about

Good idea but putting out such a low ampage it won't be much good when you come to charging 6S 5000mAh packs.

thought it was ok for starting out seems eflite dont supply it

Yeah will be ideal for starting out acctually, ignore my post.. Charging a Blade batt is prob only gonna pull 1amp.

New 400 watt psu here £8
I'm not sure what current the 12V rail is capable of but would have thought around 15A or so maybe more.
Edit: Looking at the specs it should be good for 25A! thats enough for a cellpro 10S.

Is a good way to start especially if your cash strapped like most people are when they first start this hobby, i never did get why E-flite didnt supply a mains power lead but then i suppose not many people (except me) would be flying it indoors.

To save any youngsters on here from frying themselves, can I state the obvious here (copied from one of the links above) -
Warnings

• Line voltage can kill (anything above 30 milliamps/volts can kill you in a matter of time if it somehow penetrates your skin), and at the very least give you a painful shock. Make sure that you have removed the power cord before doing the conversion and have discharged the capacitors as described in the steps above.
• Do not touch any lines leading to capacitors. Capacitors are cylinders, wrapped in a thin plastic sheath, with exposed metal at the top with a + or K usually. Solid-state capacitors are shorter, a little wider in diameter, and do not have a plastic sheath. They retain a charge much like batteries do, but unlike batteries, they can discharge extremely fast. Even if you have discharged the unit, you should avoid touching any points on the board except where necessary. Use a probe to connect anything you might touch to ground before beginning any work.
• It is strongly recommended that you discharge the capacitors. Plug in the power supply, turn on the power (short the Power (green) wire to ground, then unplug the power supply until the fan stops spinning.
• This will almost certainly void any warranty.

Excellent....well done Phockzie!!

I managed to get an old Laptop power supply from work for nothing, although they are available on Ebay for about £10 or £15. I got a Toshiba one with a DC output of 15v and 6amps which is more than enough to be getting on with. The only thing I had to do was change the plug so it would fit into my charger.

Probably abit safer if your not really clued up about electricity and electronics.

This is probably what I will do too from the various chargers and adaptors I have. I guess 15V is not over doing it then?

[phockzie]

Just make sure your charger can support up to 15V happily.
