I am new to electric and have reviewed the FAQ section. Is there a rule of thumb for cooling inlet size vs cooling outlet size. I want to electrifty a great planes super chipmunk. I am assuming 15 lbs for weight. According to Maxxprod website I need alot of voltage/amps. 10s lipo.

How do I know the size of the inlet and outlet holes? So I can see if there is room to put them etc without sacrificing structural integrity?

How long does a 10 s pack typically take to charge at the field?
