Walkera V120D02S is a great durable and ultimate stable 3D machine when it comes to 120 Size mini 3D helicopters. Offering solid 3D performance with torque tube and BNF with Devention Series radio this is just one helicopter that you can not resists. Awesome Main rotor head speed and rock solid gyro performance enables to you pull daring 3D moves on this bird with ease if you have mastered them. Enjoy this flight. Guess I have to do a bit more fine tuning of settings and programming on Devention 8S radio to tame this wild bird.
