Question Mini Titan Servo Setup on DX7

TT Mini Titan 325
3 x Hitec HS65MG servos
1 x S9257 Tail servo inc GY401 Gyro
Spektrum AR7000 Rx & DX7 Tx

I having problems getting the swashplate to move correctly and within the manual for the heli / Tx it does not tell you I guess you need to just try but i can't solve the puzzle.

Servo configuration is as follows:-

Servo at the back of the heli is in the Elevator channel
Servo at the left ( If front of heli is facing you ) is in Aux1 channel 6 ( Pitch )
Servo at right ( If front of heli is facing you ) is in Aileron channel 2

Gyro sensitivity cable Gear ( Channel 5 )
Other cable from Gyro Rudder ( Channel 4 )

Tx settings are set to 3 servo 120 degrees CCPM

Servos reversing settings as follows

1-N, 2-R, 3-R, 4-R, 5-N, 6-N, 7-N

With these settings the only problem is when giving forward Elevator the swashplate tilts backwards and not forwards.

Also is is true when the collective ( Throttle Stick ) is increased the swash plate should be moving down.

Its just on my Trex 450 it was around the other way.

Any advise greatly appreciated as this heli has been grounded for too long.

Try using the swash mix menu... You can set the values negative to achieve a different direction. Try setting the elevator reverse switch to opposite of what you have now, then in the swash mix menu, take the elevator to -60% or so

Excellent got the swash going in the right directions now. Left the servo reversing setting same and just need to change the Swash Mix to -60 on ELEV.

thx...
