GROUP 1 - Primary wing Activation(Decends in relation to throttle, once at 100% throttle can be deactivated again) For take off reach a speed of about 120mph then activate 1. This will produce a lift, just pull back and your in the air. GROUP 2 - REAR BAY DOOR( Activate group 2 and the rear bay door opens with BRAKE, deactive the group while its open to have it hold open) GROUP 3 - Main Thrust Engins( for traveling top speed or carrying heavy loads) This plane is intended for transporting and deploying ground vehicals/tanks. I will be coming out with a usable tank to be carried in this plane in the future. LANDING - this plane will land with the primary wings out or tucked up(its starting position) to land with wings tucked however you will need to come in close to the ground then cut throttle while group 1 is activated. It is probably easier to land with wings still out but its easy with some practice both ways.NOMODS, HAVE FUN!
