I am very impressed with these servos. The build quality is obvious when you take them out of the box. They are dead silent at neutral, center well, and are very powerful. In fact, a good friend and I were doing the final assembly of my Ultra Stick 30CC's together, and he commented on how quiet my servos were compared to his. His next comment was "I'm going to order a set of those".

These servos run smoothly, and provide responsive flight control.

They are my first ProModeler servos, but they won't be my last.

I have these on the rudder and ailerons of a 76" PAU Extra 300. I picked this particular on for the balance between speed and power. So far they have not disappointed me. They center great, the speed it what I expected and they seem to have plenty of power. I plan to do a wide range of flying with this plane, from IMAC to 3D, which is why I chose a balance. I love that Promodeler has so many options as far as price point, power and speed. And they seem to be helpful in choosing what's right for you. I had someone reach out to me about a purchase I made, and I responded figuring they may take a while to respond if at all. He responded very quickly with an answer. That means a lot to me. I have made the last several plane purchases based on how well support responds.

These are the first ProModeler servos I have purchased and I’m very happy. The build quality is fantastic, nice fit and finish, and they operate flawlessly. I’ve owned servos from just about every name brand out there but these are at the top of my list from now on.

Thanks and greetings from Ecuador. My first impressions were as follows: high quality finish, precise centering, soft start, smooth movement, powerful, and includes the best hardware of any other brand of servo. Good job!
