As much as I like many Hitec products I am at the point where I simply won't buy any more of them. I had an issue with their digital servos when they first came out. They would lock when exercised. I tried all of the things their support asked me too which included changinv extensions and recievers but the problem was still there. I sent them in and they reprogrammed them but the problem still existed. After going back and forth I got upset and threw them away. I have freinds that have had nothing but good experiences but most have had at least one issue. In my opinion if their is a defect in the system they owe you a new plane and engine. That said the few hitec products that I continue to own do work fine but I limit my future purchases to JR or Futaba as I run both currently.
