Guys Not sure if this has been covered before, but it just came to me looking at the site. For those of you that have a radio with no end point adjustments, but want to use a ESC, it looks like the Servo City Servo Stretcher will do the end point adjustments for you. It's $19.95. http://servocity.com/html/180o_servo_stretcher.html
I have a couple of those. I was originally planning to use them as part of a crude fire control computer, but the rapid development of the Morgret Fire Control eliminated the need. They were just collecting dust before, but now I know what to do with them. Thanks, djranier!
NP. It will be a little harder to adjust the end points, vs using a radio, but still much better than swapping out pinion gears to get on speed.
