Hey stickshaker,
don't go higher than 3000rpm initially until you gain rudder authority at about 120 kph and use differential brakes.
Again, go higher than 3000 rpm and you'll get kicked off the runway.
That is a common theme with high performance aircraft, especially tail draggers. If you recall the many stories of old head Corsair pilots getting together outside to watch the newbie conduct his first taxi in a Corsair. They are all prepared for some hearty laughter expecting that the uninitiated Ensign will cob power to start taxi and end up spinning the Corsair! That's how much torque and p-effect those aircraft could and did produce! Having it sitting on the tail wheel just exacerbated the p-effect and the torque never relented.
The trick is to takeoff at below the critical power until you exceed the airspeed required to get sufficient airflow over the rudder so the rudder can counter any further increase in p-effect. This is also further assisted by the fact that when the tail comes off the ground, there is a sudden reduction in p-effect. You also have to anticipate that an apply a little less rudder pressure to coincide with the reduction of p-effect.
This is why flying a tail dragger has a bit more demand to it. So, what Mathias is describing is very, very realistic, and further reflects the accuracy of his virtual aircraft!
