Had a bit of a crash with my Eolo, and stripped 3 of 4 Hitec 81s (tail OK, just the ccpm servos). Put new gears in all 3. Now the servos all want to go one way, all the way to the stops and grind there. They don't seem to know center. Cant get them to run the other way. Are they junk at this point? Should I have them fixed of junk them ($17 each)?
