Some of the claims on the box are just plain *WRONG*.

Karbonite *is* stronger than nylon but it is most certainly not suited to any application where there's going to be any kind of shock-loading of the geartrain (ie: high vibration with big control surfaces).

I don't know what your consumer laws are like but here in NZ, Hitec would likely be liable for losses.

Karbonite is okay when used within its *actual* limitations (rather than the claimed ones).

My HS475HB servos work just brilliantly.
