FAQ » Futaba Transmitter Input Problem

Hi Harry,

neXt needs a joystick-compliant input signal, ie values between -1 and +1. The standard receiver signal goes from 0 to 2. This is the reason why half of this signal is cut off in your case.

It is necessary to adjust the servo center point and travel on your transmitter. Take a look at the input monitor and move your sticks. The slider should not skip.

Use the servo center adjustment in your transmitter to move the sliders as far as possible to the center in the input monitor window. The channels must not exactly be located at zero.

Disable unnecessary channels in the input monitor.

Before you start the calibration, go into your travel adjustment menu of your transmitter (on Futaba these are called 'Endpoint ATV') and limit the servo travel. The output should never skip or limit at 100%. Reduce the servo travel in your transmitter if the input monitor shows + or -100 before your sticks reach their physical end of travel.

All the best,
Klaus
