The sender id should be the id of the ground station, but has it has
no effect for now, so it's not your problem.
The SET_ACTUATOR message is only working if you run the firmware
"test_actuators" on your autopilot. It has no effect on the normal
autopilot (target "ap").

Hello, i want to understand the massage protocol. An

c ac_id 01 = sender_id???
D Checksum A (sum[B->C]) = 27
E Checksum B (sum[ck_a]) = AC
where checksum is computed over length and payload:
* ck_A = ck_B = length
* for each byte b in payload
* ck_A += b; ck_b += ck_A
ck_a = ck_b = 11
b = 2
Is there a mistake or complete false?
I have send this massage over gtkterm....but the elevator servo do
