Most of the suggestions are good ones. I currently have eight R/C models, all with tail wheels, and have hundreds of hours flying full scale tail wheel aircraft. Based on this, here is the most effective way to take off in a tail wheel aircraft, model or full scale.

Trim the aircraft for a gentle climb. As you advance power to take off, initially hold some up elevator to keep the tail wheel on the ground. As the roll begins, relax the up elevator and concentrate on keeping the airplane straight. Be very gentle on the rudder as it doesn’t take much correction. As the speed builds, the tail will lift to place the aircraft in a slight climb attitude. Just keep it straight and when it is ready to fly, it will lift off in a gentle climb and will have plenty of speed to avoid a stall. As soon as it leaves the ground, transition to aileron control for direction.

It is unnecessary to use the elevator to “rotate” for take off and that is where take off stalls are likely to occur. The most common problem with take off in tailwheel aircraft is over control with the rudder. There is a bit of lag in directional control on the ground and by the time you see the aircraft respond it’s past time to release the control. It’s really not as difficult as it sounds. Just be gentle with the rudder and you will master it in no time.
