Yeah, I send a warranty request each time. Here's the last one: "we apologize for the issues, unfortunately we do not cover replacement parts such as the battery door. The warranty is more intended towards the electronics in the vehicle, not damage caused from running the vehicle."
I knew Redcat wasn't the most durable RC out there (see YouTube), I am disappointed with all breakage. The battery door broke while removing the battery door, not driving. Since it has been driven, it seems that all plastic damage is on me.
