Servos is another topic that can hold a lot of debate. I would say buy standard servos, or maybe bb servos, you really don't need much more power on either of those planes, unless the spec tell you so. I have a friend that has been flying for a long time, and he always reminds me that not that many years ago, servos only produced small amount of power 14-20 and planes flew fine with those. Then the "standard" servos would fly just about everything else. If you have a ton of extra money, but more expensive servos will work a little better. but I would not spend extra money on servos for a second plane. just buy and fly.
