 I too had difficulties with my Sorceror.  Problems stemed from having
 the wrong servo, old software, and the very earliest hardware
 (practically a beta version).  TruTrak folks were responsive, upgraded
 their stuff, and the system seems to be working fine now. I'll know more
 after flying for 6 months.
