The problem with older servos that are analog is it's harder to use them with a high voltage system where your newer, high torque high voltage servos are operating at 7.5-8.4 volts on a lipo or Life pack.

While a HS 645MG is an awesome analog servo for far less than an equivalent JR, it's a low voltage servo. I use those too for my 6v systems though and also for prop warbirds. Never had one fail.

As far as the advice to not use digitals on steering servos go, I think all the car guys now are using digital high voltage with appropriate torque values. You can't get more abusive with a servo than running it on a 1/10 scale offroad car. I would not want to use a marginally torqued digital servo but one that is appropriately rated for plenty of torque - I suspect - would be fine for aircraft nose wheel steering.
