Thank you all for your answers!! I have now set the throttle range once again and then removed the red wire from one ESC before i connected it again in a y cable.

It seems to work fine now!

I got another "problem" though... I have glued it all together and when i move the elevators sometimes the servos are shaking.. and you have to move the stick to make it stop...


I have attatched a picture of the Tomcat.
