the Volcano SV is not really a monster truck at all, it is more of a "jacked up 4x4" and i am not going to be racing since the closest track to me is probably a good 4 hours away... all i am looking for from this thing is dependability at a reasonable price. Sure if i had more money i would just buy a better truck but at this point in time i can't justify it since i only need a few servo's for this one.
i think my biggest problem is that i don't really know much about this stuff because i am stuck down at the shop all day (i am a mechanic) and on the weekends i am often resting or helping a friend with something which doesn't leave me with a lot of time to research. something that would help me a lot is if you guys could send some links with your suggestions.

I'd go for 2 of these, $36 ea
MKS
The closest thing from Hitec is the 645MG at $32 ea, but they are much slower, less torque and metal gear vs titanium for the MKS.
I have a few of these 645's and while they're not crap, they're not great either. I've broken the gears on 2 and had one burn out.
Savox is your best bang for buck, and these MKS look ok too.
Never tried the MKS personally, but they are are sponsor here so they might be good.
The savox one's to go for
$37.99
$39.99

so i am thinking i will probably go with some Savox servo's but i only have one question... and it very well could be a dumb one so hold on to your hats!
i have noticed that all the Savox servo's say they are "Digital" where as some of the Hitech servo's are "analog". my question is will a "digital" servo work with the receiver and transmitter i have. They are nothing fancy, it's just a AM transmitter with a few advanced controls and a 2 channel receiver... not sure what more information i can give you guys/girls.

Buried in this document is an explaination of why digital is better. Digital will work for you.
"The result is a servo that has a much smaller deadband, faster response, quicker and smoother acceleration, and better holding power."
