If you have EXPO on, that will slow down response. I'm still learning on my Hirobo EVO .50 and have never needed EXPO.

Suggest you find a seasoned pilot at a local club to check out your Raptor there may be several things not quite right you may or may not know about. An experienced pilot can help sort out any issues and test fly your baby for you. That way you can separate mechanical issues from uh, "learning" issues!
