All these tolerance sum up will give over 0.5 degree error of readings, or even 1 degree for some pilots. This is why we normally use another method to measure the pitch.
We are glad to announce our new product – GS3-2423 Tail Boom Support. It can further reinforce the structure of tail boom and fiber frame. With the support of 2 x 2mm Carbon Fiber force, viberation from tail can be damped away, which gives a more solid rudder to the whole helicopter.
