I fly mainly with the aileron and elevator but I do also use the throttle sometimes.
LOL! If you "sometimes" fly at less than full throttle you're finessing more than many long-time pilots I know.
Line up your approach for landing and work he throttle down. With some models you can drop to idle and glide in (I'm very guilty of that), but a good approach is flown in and throttle is lowered gradually as the model settles. If you ever move to a high-drag model that is a good skill to have in your toolbox.
Horizontal figure-eights are a great learning tool. If you are doing them right and keeping them symmetrical it teaches you to work both upwind and downwind.
