This servo is hands down one of the best digital metal gear servos I have ever used. Installed 4 in a 48" MXS, with 475 watts and a 48" EF Lazer with 750 watts. I am close to 50 brutal flights on each and have had outstanding performance from these servos I even crashed one of the MXS beyond repair and the servos were undamaged and were put in a new MXS. The horns could be a little longer but only because I like 50 degrees+ deflection. I love these servos and at $8 each you can't go wrong and if you have any questions or problems customer service is better then 100% in my book.
