consider aircraft, most transmitters and receivers have the channels named for them
mode 1 has throttle on right (up/down)
mode 2 is throttle on left (up/down), generally the UK set up.
Some transmitters can be set whichever way you want. When buying one, ensure the throttle stick is sprung centred, so you have the function of reverse. Planes and helicopters wont have this, (obviously don't go in reverse) so you will have to do a conversion to achieve this.
Flysky and hobbyking have good budget sets, most will have 6 channel receivers, you will ned at least two, throttle and rudder, anything extra you intend to do, such as lights, sound and so on will need more channels
