500 Servo arm 90 degree

[UnGwan Hwang]

Hi,

I am a beginner of building Trex 500 DFC Pro. This is my first time to build it. I have a question that is how I can put servo arm 90 degree on the servo. My transmitter is Spektrum DX8. I use 3GX with 2ea DSMX satellite receivers. How I can put servo neutral point. I am supposed to use 3GX DIR mode, and then I put servo arm 90 degree on the servo. It is correct or not. Please answer my question.

Regards,



UnGwan

Hi there,

set up a liniar pitch curve and throttle curve. remove 1 or 2 of your motor wires to eliminate motor firing up.... set your throttle stick at 50% in the pitch curve mentioned before 0,25,50,75,100

and go into DIR mode. ...... then set your servo mechanicals up .... use your sup trim to get that last little bit out to get true 90 degrees.

Always unplug 2 or more of the wires. Unplugging only one and the motor could still spool up.
