You can almost always substitute another servo in the same or greater range of output torque safely.

The 332HD's will work just fine.

Ball Bearing servos will last longer versus Bushing based servos so they are preferable.

But the choice is yours...

Remember that there is some very good likelyhood that even a bushing servo will outlast the plane.

In your shoes I'd opt for the cheaper servos in the 3D plane, knowing that sooner or later I AM going to crash it, since I'll be flying it low and close in.


A .60 ( or larger ) Edge may hold up longer if only because you may fly it out further and higher, giving you more time to land and react... so I'd put the better servos in that plane.
