QuadPlane Configuration - VT_TRANS_THR does not exist

Open hamishwillee opened this issue 6 years ago • 3 comments

QuadPlane Configuration > Transition throttle

This links to VT_TRANS_THR which does not exist. Did it get replaced or disappear?

@RomanBapst Is this a question for you?

@hamishwillee

VT_F_TRANS_THR---> Target throttle value for the transition to fixed wing flight. VT_B_TRANS_THR---> Target throttle value for the transition to hover(Multi-rotor) flight

But I didn't find the setting of transmission throttle in tailsitter type

This function also seems to have no effect（_thrust_transition always 0.0）： https://github.com/PX4/Firmware/blob/master/src/modules/vtol_att_control/tailsitter.cpp#L270 （_v_att_sp->thrust_body[0] should _v_att_sp->thrust_body[2] ？）

Thanks. We need @RomanBapst to comment - it isn't just a matter of replacing the existing parameter in docs.

Yes, I already know that in tailsitter drones, the thrust when switching to fixed-wing mode is generated by multi-rotor altitude control Instead of a parameter, we do need to clarify some instructions :smiley:
