Hi Nonato,
No mate no locking on the Boston.
the trick to nice take offs with this plane is:
1. feed on power slowly, get her roling then feed on throttle for take off speed.
2. use the rudder to counter swing, gently does it though dont over correct.
3. use the differential brakes to help counter swing if the rudder is not giving full correction.
4. be patient dont try to lift off to early. let her have her space then ease the nose up, gently climb until full flying speed is achieved.
HTH's
