Hello,

I have been in the hobby for a few years already, but always using glow engines and I never considered electric flight because it was restricted to small planes or were lacking performance, but the technology advanced quite a lot recently and I decided to try an electric plane. I already decided on the model(GP Extra 300sp) and the motor, esp and everything else.

Now the first questions I have are regarding the batteries and their use. First of all I would like to knowapproximatelybefore I fly how much flight time would I have with my batteries. Is there a way to calculate this? To know at least an approximate number? With glow engines I simply fly a while and check how much fuel do I still have in the tank and come to an approximate number, but with lipo batteries for example, I should not let them discharge completely because I could damage them so how would I know how much can I fly? also what is the discharge limit?
My second question is in the same area, how much time would it take for my batteries to charge? I will be using 2 x 3200mah 3s batteries in the plane for a 6s config. If it takes much time then I should buy more packs so while I fly, the other packs are recharging and I do not have to wait a long time between flights? Also because I am using 2 batteries should Ipurchasea charger with multiple charging leads to speed up the operation?

Now in another topic is it true that I can not fly the airplane in full power for a long time?

Sorry for the long post but I wanted to explain myselfthroughly and thanks for theanswers.<br type="_moz" />
