I have been having issues with the servos on my xb. And to top it off I haven't been able to get a replacement for the steering servo as most hobby shops don't normally keep them in stock. I was able to get a savox sa-1231sg which is a 1/10th scale servo with a torque rating of 444 ozin at 6v. In order to make it fit on needed an adapter, so I designed one that bolts into the existing mounting bracket and printed it out on my little printer. If anyone is interested in or needs a similar fix send me a message and we can work something out. I will post a pic as soon as possible
