I have a XTM X-Crawler and have pretty much given up on keeping a servo on it. I have just gone to useing the cheap Tower Pro servos on it now but they aren't strong enough to start with but last just as long as the $100-$150 servoes I have used on it. Does anybody have any suggestions to a good servo for X-Crawler? I have tried JR and Airtronics metal gear servos that the lhs said had plenty of power but one JR lasted maybe 10 minutes and two others lasted maybe 3-4 batteries and the airtronics lasted about 3-4 batteries. I am tired of throwing money away anybody have any ideas.
