Thank you for replying so quickly! This is been very frustrating to me. Thank you for replying so quickly! This is been very frustrating to me. Yes, I did release the stick back to the center position. I have also just now discovered that the running mode to revving mode switch that uses number 4 trim also does not function. As a “newbie“ I do not know if or how to configure or calibrate the trims . Any further advice would be appreciated. Again, thank you for your reply.

I am building a Tamiya Grand Hauler (#56356). I am installing the MFC-01 MFC (#56511) and using the Tamiya Attack 4YWD-2.4G Radio Control (#7255252) with the supplied 4-channel receiver. I am building the Flatbed Semi-Trailer (56306) and using the Motorized Support Legs kit (56505). I am using a Hitec HS-322HD servo for the coupler. Everything functioned perfectly right out of the box with no adjustments needed EXCEPT the coupler servo will not operate. I’ve checked all the wiring several times and am convinced all the connections are correct. I’ve plugged the servo into the steering port to prove that it functions (if does). On page 10 of the MFC instruction manual, there are instructions for switching between Horn mode and Support Legs mode. “Slide 4ch (L) trim lever completely to the right. Push the stick completely to the right to conduct the following operations listed below.” I do this, but the right stick continues to be in the horn mode. It will not operate the coupler servo. Anybody have any ideas how to fix this?
