I pretty much wore out the brushed motor over the last two months, so I upgraded to the 370 this weekend. I went ahead with a headlock gyro as well. Still learning and mostly hovering only at this point. After the upgrade, something is not right with the new gyro or who knows what??? Full right rudder won't stop the clockwise rotation when I run up the rpms. I've double checked the instructions and things look right. Any ideas would be welcome, or can someone send me some troubleshooting tips. I plan to bypass the new head lock and put it back on the three-n-one unit tonight to see if it still works right. The only thing I must fess up is that I didn't have a 8 tooth pinion and used a 10 tooth one instead. I don't know much about helis yet, but didn't think that would matter much. My tail motor seems ok, but I really wouldn't know. It stops when I give it left stick, and runs when I give it right. Maybe it's wore out too and don't have the necessary power to counter the brushless torque?? My local Hobby shop is worthless. I know you guys can help....I missed my little heli all weekend. ;o(
