I thought I would post this. Bought a trollmaster this winter and it worked great until Thursday. Call up trollmaster talk to a man there how help trouble shoot the problem. I end up taking the servo off and taking to a local hobbie shop to have it check as per the man I talk to. The clerk said it was bad, so I called back trollmaster and they told me no problem will send you a new servo. Well they did and now it is working great again. My hats off the people who work a trollmaster. It is nice have a company stand behind their product and the speed to get me backup and running again. Thank you.
