On take-off don't worry about setting a climb to altitude record. When I send my King Kobra off (far from a trainer, and not forgiving like a Tiger II), I clear the end of the runway at only 25' at best. I let the plane build up speed (in this case to 50+ mph, the Tiger II doesn't have to be this fast due to its slower stall speed), and then make the first turn at no more than 45 deg bank just to avoid an accelerated stall. I fly my student’s trainers the same way - build airspeed straight ahead to make sure the plane has adequate airspeed and is well above stall speed before banking. Over time you'll learn to feel what the plane is doing and sense when it’s getting close to a stall, but it takes some experience to get to this point.
