Offboard control without connected RC

Hello all,

We are currently trying to get a pixhawk multicopter flying without any RC connection. The plan is to control the copter solely via Mavlink (& Mavlink shell). More specifically we intend to use manual controls to actually move the copter.

However, trying to to this without a connected RC input_rc.rc_lost & .rc_failsafe is triggered. Is there any predetermined way to exert control without any RC present?

Thanks, Karsten
