RE: Please solve this one!!
Every plane is different but each of the tail draggers I have flown require some up elevator input to keep its rear wheel on the ground until it builds up enough speed for take off.
Bi-planes and tri-planes are the worst to nose over often a pilot must hold on to it until prop speed is up and launch will be very short. I have an Avistar tricycle gear. To fly that I must set my mind to not do the "up elevator" habit.
Taking off is not the easiest thing to do. It a mix of elevator, rudder, throttle and ailerons when applicable. That must be just right for a perfect take off. These skills come with practce and help from an instructor.
For me; mainly flying off a paved surface; a wheel is a must. I have a little electric (Quite Storm) that had no tail gear included, just a skid. It had a rear tire before it made it out of my workshop.
I could easily toss that pane but part of my enjoyment is the taxi and power on to a smooth climb. Personal preference mostly and it gives the plane time to show any problems on the ground before I commit to flight.
