One of them is going bad and they are pretty slow would like a faster one for the throttlebecause the Eagle 2 is a high wing trainer, I'm going to suggest sticking with those and get your money out of them. You don't need super fast servos on that plane, you just need something that will control it, and those have been around for YEARS! I think I have some of those in a couple of my planes lol.
why are you wanting to replace them by chance?
If I replace them with same futaba ones they are around $ 16 each on amazon I would need 3 there is only one for aileron but still would like a quicker one for throttle but don’t want to put a 70 dollar servo for throttle may something around $20 to $30 rangeWhat kind of budget are we talking about here? Per servo that is. So either 4 servos or 5 depending on if you have separate aileron servos. No matter the way, it's going to be expensive.
