<DIV>Ryan, you just answered your own question! If you took it out and it flew fine and you can't imagine how it could fly any better, why in the name of all things holy would you change it? No matter how much truth there is to the notion that better servos make the plane fly better, it is almost never a good idea to fix something that ain't broke! Fly your Summit III and fly it a lot. If the servo issue is something burning inside you that you must explore, try it with your next plane. Here is why I say that, the new servos will likely change the feel of the plane, they may be faster, stronger, or just different. If you don't immediately like the new feel, or trim changes, or whatever, you may lose confidence in a plane that you previously thought flew great. Couple that with the knowledge that you paid nearly $200 bucks to make it fly different and it is easy to imagine your dissatisfaction. From the tone of your email it didn't seem like you were too keen on spending up to
$100 bucks a pop on top of the line servos. Given that, it has been my experience that unless you are a significantly better than average pilot, or extremely sensitive to the feel of your airplane, you will not notice a huge difference between a premium servo or a sport servo. Last but not least, if memory serves me correctly the Summit III is a 60 size plane in the 7 to 8 pound range. I don't really think that will benefit from a top end servo. Personally I use a mixture fo JR and Airtronics coreless and digital servos. When I moved up from sport servos the main difference I found was speed which was huge for me and took some time to get used to, and an ability to lock on hold trim position. I like my good servos, and they helped a plane that I thought just flew OK to fly a lot better.</DIV>

<DIV>Good luck with your selection and I hope you find what you are looking for.</DIV>
