You should be able to power 5 servos with that ESC. If you are doing 3d flying then it may need a separate BEC, but that's only if you are really moving the sticks fast. You either want a smaller motor, or a larger ESC since the motor draws 30 amps, and I always like to have a 10 amp buffer from the ESC's rating and the motor's max amp draw, just in case the manufacturer is lying or inconsistent, especially with the cheap ones. The battery seems like it may be a little small, it really depends on what plane you're making. You may want a 2200 mah 3s, or an 1800mah 3s. It really depends on the plane. As for transmitters, unless you're on a really tight budget or just trying out the hobby I'd recommend getting a 6 channel Spektrum, Frysky, Graupner, Futaba, or any other well known brands. If you are only trying out the hobby, Hobbyking sells really cheap 4 channel transmitters, and Flysky sells cheap ones too, you just never know if you'll be able to get a refund when it doesn't work (in my case I wasn't). For chargers, I don't recommend getting the cheapest possible ones since it won't charge your battery the best way sometimes, and that dramatically shortens lipo life. I first got a 18 USD charger and used it for about a year. All of the lipos I charged with it died about half a year later. I've had my Prodigy for 2 years, and all the lipos I've charged with that much more frequently have yet to die. I recommend the Protek Prodigy which only costs around 50 bucks. It's very capable, and it can also discharge lipos. Welcome to the Hobby
