best,
Totally agree with you that having digitals isnt gonna make you faster. I dont care much for a throtle servo (but I do like the fact my S9550 is light), but I do believe in having a good fast/storng steering servo. If you steering servo sucks Ie S3003 like on my tamiya car, then you are gonna be all over the place. you know what I mean?
