hpi rs4 evo 3 servo and battery question

[SewerBeing]

Hello,

I currently have the stock radio, servos and battery setup (4 AA batteries). I want to upgrade the radio to an airtronics MX-3 and while I'm at it I want to get some new servos (at least for the throttle since for the ABS it said a good servo is well a good idea). Though if the stock servos will work fine then I will stick with those. In the $50 or below range (per servo) are there good ones I can get? (I was looking at this one: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXDWF8&P=0). Oh also this is random but does the following tuned pipe fit the stock engine: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXCPX4&P=SM

Thank you!

A 5 cell hump pack would make the biggest difference in servo performance.

Just to be sure I don't order the wrong thing do you mean something like this: http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXNMD7&P=7

You got it. You should be able to find a switch harness for a few bucks as well. That's if you even need one. If your 4aa holder is hard wired into the switch, it's easier to get a harness with plugs. They have a little pig tail that allows you to charge the hump pack without removing it from it's box. You'll need a charger that charges 5 cells at 1 amp or so as well.
