Spoken like a true JR guy
- he forgot to mention than JR cost an arm and a leg for gear replacements which JR need constantly
If you want a good servo, good centering, and don't have to replace gears every 60 flights you buy Hitec 5955s like most Hitec and all the JR guys who woke up do
Sorry RcP I couldn't resist
The 5645s are known to have a centering issue... personally it's not as bad as some make it out to be. If you are just knocking it around and doing sport flying then you will be fine. If you want precision flying you need to move up to the 5885. The issue is that if you are going to spend the money for 5985s then you might as well spend the extra $20 to get a 5955 so that in a year you dont have to spend $17 for a new gear set.
Lets not forget with 5955 they are usuable in every airframe you grow into as time goes on.
Hope this helps
