Both my e's have mambas and the super cheap servos and are in need of upgrades. Which servos best for this set up?
XP DS1313 for 1/10th, XP DS1015 for 1/8th.

Best servos there are for the money in my opinion, you have to spend quite a bit more to get better, although these aren't cheap either, to be fair. Don't listen to people who bad mouth them, there was a single faulty batch years ago, and they've been trying to shake the rep ever since.
