Saw these Viper products at my LHS and was wondering what the big difference is between the VTX10 and VTX10R if anyone can help? From what I gathered the VTX10R allows a slightly lower T motor... 6.5 vs 2.5 for the VTX10R.. I plan on running in a SC 10 stock class so a 17.5 Viper motor is quite possibly in my future...

Given these facts, I could run the VTX10 and have, what i'm asumming, the same performance and save myself like 40-50$.

Anyone provide insight? Thanks!
