yeah I think SP/HW/Orion are all the same and made by the same people. But if you switched to castle or Viper would your adapter still work? It seems to me like it would just be an adapter. All of the esc information is in the firmware of the esc. If the windows driver is specific to the adapter, then i can see how the software may not pick up your esc. The castle adapter actually powers the esc and the rest use the battery. So I can also see how that might not be compatable.
