Jet trainer?
Mike is correct. My Enforcer was rather dangerous on takeoff roll. The nose gear was very effective for a slow speed taxi, but in the regime above a fast taxi, and before you are airborne (where the nose is very lightly on the runway), it was sometimes a crap shoot where she was heading if there was a cross wind. It was manageable as long as you realized this at the start of the roll and biased your takeoff direction, but it would be far better to have rudders or rudder.
