Spectra Motor Assembly
 

I recived a spectra a while ago, it is partialy assembled. However it doesn't have any part of the motor or speed control stuff. I am looking for an inexpensive way to buy or build the ESC or on of switch that can be remotely operated by the receiever. I know the plans call for a on off switch opperated by the servo. I found tower is selling a ESC for 18 dollars or so. I was wondering what you all thought about it. I also will need a battery charger. I have an accu-cycle that will work, but it will take forever. If you know where some plans are to build one or where a cheap charger is, could you please let me know. I also wanted to know about BECs, are they safe?
So to outline
1 Motor assembly on the Great Planes Spectra
2 Motor Contol on Great Planes Spectra
3 BECs ESCs what are they what do they do
4 Charger, cheap or buildable

Thank You very much

You need to do some homework to learn the basics of e-power systems before you buy anything. Using a servo operated switch to turn off a motor is quite obsolete. You need an ESC (electronic speed control) which gives you throttle control. The ESC you buy must have a capacity for the number of cells in your power back and the ability to handle the amperage that your power system will draw. BEC (battery eliminator circuit) is a feature of some ESC's that taps the power pack to supply your receiver so that you will not need a separate receiver pack. It will also include an automatic voltage shutoff to the motor. Can't imagine what could be "unsafe" about this. A quality charger is a must and it will be about $100. You need a peak-detection charger that will handle the packs you will be using which runs from a 12v. supply. Flying e-power successfully is not cheap and needs serious planning.
