Hi. I am building a model battleship and have put one servo on each main gun turret. 4 in all. I have connected all the servos via a 4 into 1 lead. Everything works fine except 2 turrets turn left and the other 2 turn right and vice versa. I connected a servo reverser to 2 of the servos but only one works and the other 3 don't function. Any ideas please

Any reason not to put them on separate channels?

You probably have signal level problems, or bad Ys. Make sure your Ys are all good first - actually, you want a 3-way Y and a 2-way.

For signal levels, boost the output using a boost such as SPMCP. A fanout of 4 is a pretty hefty load for a single port. I would put one directly into the receiver - this will supply the 2 servos plus the reverser. Then put one on the output of the reverser so it feeds both of the other two.

Thanks for your reply. It was my fault for not checking the rotation when I built it all. I will just have to accept the front guns turning in a different direction to the rear ones. The servo reversers looked at first glance to be my answer.

What radio are you using? Does the TX allow mixing and reversing? If so and you have enough channels can you mix the opposite turret Y harness to correct rotation turret y harness. You would then be able to reverse the mixed channel in the TX.

Thanks for that. I can change my TX and see if I can mix as you described.

If your servos happen to be digital Hitter you can buy a programmer and reverse them.
