 Thank you bob, 



 I haven't see the response before and I answered in other topic. 



 I will try it and I will come back to tell if it run better or not. (if it run well also to tell what it was bad if it can help anyone.)



 I find relay a bit slow for the motor trim operation, we haven't another solution to wire it with another system ? (transistor ? I don't know well what is it, I just read that on internet) 	


   What do you mean my "slow"?  Running

   speed of the motor? Response delay to

   pilot input?



   Virtually every trim system I've worked on

   over the past 40+ years is controlled by

   relays. They're smaller and perhaps a

   little bit faster than the suggested

   automotive relays . . . but the difference

   would be described as a few milliseconds.



   The relays can be replaced with transistors

   but let's see if it's really necessary. 



 

   Bob . . .

Yes in respons to pilot input. 



Little input didn't run the motor, a bit large input pass through the value desired. (no possible to adjust it precisely) but maybe it's not the fault of the relay. More in the trim system made with a spring,  which  can increase the imprecision, taking into account your response. 



If all system are made with this kind of relay or close to, I will think about all system before looking on the electrical part so.



(photo not very important helpful but a least we can see the motor)

If I understand correctly, it is difficult to adjust the desired trim position because pressing the switch either does not run the motor long enough or else it runs too long and overshoots.

More precise control can be achieved by using a lower voltage to run the motor.    But the motor may fail to start if operated with a lower voltage.  The solution may be to operate the motor with a PWM (pulse width modulated) voltage.  The type of relay used has little affect on the trim speed or travel.
