The servo reverser works well no problems at all with them and i have three flying right now. I did not have to adjust anything other than normal adjusting that has to be done. Centering the servos then use your end point adj. and there your go. Very easy plugs in just as a Y harness does and it plugs into your elev. plug on your reciever. They are great little devisces and are so much easier than trying to go thru your TX. And they are not exp. at all. THEY WORK
