Hello to all.I have this question: Should i use a Y-harness on my trainer to connect rudder with ailerons so as to have them both on one stick or should i control them independently?What are the advantages and disadvantages in each case and what would you suggest as a better option for a novice flyer? Thank you.

no don't do that keep them like they are made to go it don't work right like that

IF YOU HAVE A TRANS THAT WILL MIX YOU CAN PUT A LITTEL RUDDER IN IF YOU WANT BUT IF YOUR NEW TO THIS DO NOT DO THAT LEARN TO FLY USEING BOTH STICKS YOU WILL NEED THAT

I agree with prophanger. Y harnesses are used more for when you have 1 aileron servo in each wing (left,right) and want to hook them up to one chanel in your receiver. They work great for that.
