The control system is Caution: Do not inadvertently skip this step! arguably of equal importance to actual construction and must be given adequate attention to ensure... - Page 40 flight is to hold the airplane vertically and advance This brings us to the most important aspect of 3D the throttle to full power. The static thrust should be setup—control surface deflection. Do you need enough to make the airplane accelerate vertically large amounts of deflection to hover? The truth from a standstill.

Trimming and Flying the Tensor 4D Large amounts of throw tend to make the airplane feel very sensitive around neutral. Because of this, Now that the airplane mechanical set-up is correct, it is highly recommended that you use a radio it is time to fine-tune the set-up in the air. - Page 42 an asymmetric vertical tail configuration, the Tensor Left and right rudder knife-edges will require has nearly equal vertical tail area above and below slightly different levels of mixing because of P- the thrustline. As a result the Tensor needs no side factor.
