RE: Is a digital servo better?
Just a comment-
I had a Hitec MG645 in my Maxx- worked AWESOME. I picked up a 5645 shortly after and discovered that it's very glitchy with
my Traxxas radio set. As soon as I put the 645 back in, it was fine.
The 5645 servo works fine with another radio set that I have. Keep that in mind when you make your decision. I know it shouldn't
be an issue, but for whatever reason, the TQ3 Traxxas radio didn't like the 5645 servo.
One more thing- Do yourself a favor and get a niMH 6V Rx pack and charger before you upgrade servos. Your alkalines
won't last as long and it's just wasteful.
