Just had a quick look over the params you posted a little while ago. You have almost the same stuff as me. The only big thing that I saw was that your aircraft is armed as soon as you switch it on? Do you not have to arm it with rudder before hand? This jumps out at me as when the aircraft is disarmed it goes into a "check" mode where you can operate the transitions and rudder with out fear of it taking your hand off.
Also is your q_tilt_rate_dn still 0? That might need to be a positive number to get it to move in FBWA transition.
Also just to double check;
Q_FRAME_TYPE can be anything I believe...
Motor 1,2 and 4 are on servo5, servo6 and servo8 respectively as 33, 34 and 36?
Front two tilt servos assigned to a SERVOx as tiltMortorLeft and tiltMotorRight (75 and 76)?
From memory this is all I had to put in to the params to get the tiltMotorLeft and tiltMotorRight servos working in the correct orientation. Then I just went through changing max and min pwm's to get everything pointing in the right direction. That was it I think.
I hope this helps, its all I can think of at the moment but I'll add to this if I think of something else.
