[Paparazzi-devel] downlink only

[Martin P]

Hello, 

it seems that I have a common problem: GCS doesn't send to the plane. Removing 
the datalink section didn't help.

Anyway, I am not so much interested in the uplink. When I am alone I cannot 
watch the plane and the computer screen at the same time. I know that Pascal 
Brisset strongly advises against removing the holding point block from the 
flight plan, but I might do just that. 

My starting procedure would be like this: 
Switch on the transmitter and switch to MANUAL, throttle off. 
Power the plane. 
Wait for GPS and do GeoInit. 
Instantly go to Takeoff (a beep or LED signal would be nice). 
As I am still in MANUAL, the propeller doesn't spin. 

I don't know how to go on from this point. When I switched to AUTO2 (without 
propeller, for safety) I expected the motor to start, but it didn't. Does the 
autopilot wait for a "launch" command which it doesn't get? Does the autopilot 
wait until I have stared manually? 

Can you take off from the lawn (with a landing gear) or do you need to throw 
the plane? 

Greetings, Martin
