Noob seeking advice on parts for ARF build
I have been flying my super cub off of the lake in my backyard for a few months now and since I wanted to try a plane with ailerons and think flying boats are pretty cool I bought a Guanli Catalina. I had read a lot of reviews saying that the electrical system and small parts in general on the plane were junk but that the plane flew well so I bought an ARF and want to add my own parts. I have pretty much settled on buying a Hitech Optic 6 transmitter so I can run both planes on it if not add more, however, I really don't know much about parts as far as quality and how to match them.
I would like to fly the plane faster than my super cub but don't want a ridiculous amount of power. Since i know literally nothing about electronics and the numbers on most parts(amps, volts, "draw"), I was hoping you guys might suggest a simple motor, esc, battery, servo setup that would be quality but not break the bank. Also if there is anything else I'm overlooking let me know.
