We are using the following hardware configuration:
Yapa2 + CHIMU + Ublox GPS + 900 MHz Xbees
After mounting the autopilot to the airplane and connected everything we tested the equipment and we noticed that when we "YAWed" the airplane we had no response from the Rudder. On the other hand, when we "Pitched and Rolled" the airplane we could see that there was a response from the ailerons and elevator. Is this correct? Should or shouldn't we expect a response from the Rudder?
About Roll control, I noticed that in our airframe file we have 2 servos controlling our airplane's roll, but our aircraft only has 1 channel moving the ailerons. Can I leave it this way? Or should I change the airframe file and erase the channel moving the extra aileron?
