I race only in the winter. I just like to test new stuff during the summer.
For a good servo thats cheap I love the Airtronics 94145. I have been using the same one for a long time without a problem.
As far as the ecs goes the LRP quantum Sport without reverse is good for the price but I would spend a little extra and get a Quantum 2 or a VFS2000. I prefer the VFS myself, but The Q2 is just as fast and much easier to use.
