Its a funny thing but I remember using ni-cads in the 70's. In fact I bought my first ni-cad in 1959.
I used to fly formula 1 in the early 70's. Our airplanes exceeded 150 mph and nobody used gyros. On take off you would put in full up and full rt rudder before it was released. After it left the ground you would sort things out.
Today when I take off a taildragger I advance the throttle 1/3 and get the airplane steering with the rudder then advance it to 2/3 and get the ac up on the wheels and starting to fly. Then give it full throttle. This is easy to practice. Get the a/c out and practice steering it around with the rudder on 1/3 throttle. When you learn this the rest will come easy.
I don't have anything against a gyro. They have their uses. If other pilots are using them in racing you probably would need to have them to remain competitive. But I think a pilot should learn to take off a taildragger without it.
