Gentlemen,

I too am considering electic F3A, but have little to no knowledge/experience. Last time I flew pattern was 20 some yrs agoon 25sized plane with a tuned pipe.

I am trying to figure out what I need to get started on the battery maintenance side. So far, thanks to threads like this one, I am figuring the following. Please help me understand better if I am mistaken and the questions below..

1. Batteries: whatever capcity and however many you can afford to have
2. Charger: whatever capacity suits your needs
3. Power supply: this is where I get a bit confused. If I get a charger that you can plug into a wall outlet, do I still need one? Also, in the field,,, if my charger takes 12V input, can't I just use my car battery without the power supply? I am seeing discussions on separate Pb batteries and even generators.... Is the capacities of typical F3A batteries so large that you need these things if you wanted to charge at the field?

Sorry if the question seems way too basic... Trying to get back into the hobby in 20 years, and things have changed way too much...

Thank you all in advance.
