RE: One or two steering servos?
I've been told the JR650 servo is pretty unreliable. You might wanna pass on that option. Check out the Monster Pak, that JR sells for the LST2. It has two 8800's in it, and cuts the cost down a bit. Also, that glitching may not be the servos themselves. What radio were you using prior to that XS3? If you have a mix of digital, and non digital servos, you can get a nasty twitch on the servos if you are using any of the hi speed functions built into the radio itself. I found this on my LST, and my muggy when using standard throttle servos with the hi response setting on my radio. Turn it off, and the twitching is gone. Just a thought. Good luck with whatever you choose.
