So where exactly is the throttle on a hitec laser 6-ch FM radio. I don't know if all of the 2 stick controllers have throttle?

Throttle is usually the left stick, the up and down motion, the one withoutthe spring return. Don't remeber exactly which channel it is, but it should be one of teh first four..

Pretty much all radios operate teh same way, a standard.. no pmatter what teh number of channels. thge left stick is throttle & rudder (left and right) while teh right stick is elevator (up and down) and bank - ailerons (left and right) Those are the basics, the basic 4 channels required to fly. Other channels will include flaps (a dial) or gear (switch) or some mixing (usually on heli radios)

For mode II (the most common control arrangement) the throttle is channel 3 on almost every make of radio now. (I know of no current radio that isn't this way)

Hitech, Futaba and JR are set up this way....(I'm fairly sure Airtronics is the same) Ch 1: right stick primary turn/bank (ailerons) Ch 2: right stick pitch (up-down elevator) Ch 3: Left stick throttle (heli collective pitch) Ch 4 : left stick secondary turn/bank. (rudder) Ch 5: retracts or switch operated aux (some have a proportional knob here... especitally heli capable radios) Ch 6: Flaps/proportional aux.

What are flaps?

Flaps are an auxilary control on the wings of the aircraft. Ailerons move one up as the other moves down, flaps both move down or up at the same time (and normally don't go up from "neutral")

The purpose of flap is to alter the stall speed and drag of the aircraft. Any amount of flap deflection adds some lift and some drag... A small amount of flaps will reduce the effective stall speed, and since the flaps are usually only in the center of the wingspan, the center will stall before the wingtips whent he flaps are down. Large flap deflections (over appx 15 deg) will add significant drag to the aircraft and any deflection more than 40 deg is adding drag and little more added lift. (single stage, simple flap systems... Fowler flaps add significant lift at over 60 deg deflection)

I have several radios and fhuber has hit the nail on the head for all of mine. Pretty much standard for mode 2.

note that for 3 channel (rudder, elevator, throttle) aircraft, it is normal to put the rudder on the right stick... since the rudder in that case is the ONLY turn control, that makes it the primary.

I'm on a tight budget(like $50.00) and I was thinking of getting a Laser 4 From hitec. The only problem is that I have a spitfire with all the servos mounted including a retracting landing gear servo. So if I get the laser 4, I cant use the retracts. I need a transmitter with servo reversing and eleron mixing
