I thought it would be interesting to post the response I got from Travis Amezcua on the subject of "lower" torque servos. My email to him is in red, followed by his reply in blue.
In the last couple of months, I've seen pics of the soon-to-be released 8ight buggy, and something caught my eye: I wasn't sure if it was yours or Adam's ride, but the car (which looked like it had been run) was fitted with an Airtronics 94630 steering servo. I wasn't sure if perhaps it was just placed in there for photography's sake or if it was the actual servo used in the car, as I thought it to be a bit of an odd choice, given it's lower torque output (compared with the more usual 150-200 oz/in servos other people tend to run.)
In short, I was just wondering if perhaps the torque from that servo was sufficient to power the steering in a 1/8 buggy, or might there be some less obvious reason for running it?
Well we both use the airtronics 94360's for all of our cars. We haven't seen a problem in torque for the steering.
There you go. Right from the horse's mouth.
