Fire,
Don't get me wrong. I am not trying to shoot down the CGM. Until just a few days ago, I had an SSG SD, I sold the car less options and spares as I planned to get the CGM.
The chassis weight bugs me because I have normal sized electronics.
Graphite tubs are generally more resistant to flexing, especially when compared with their standard plastic counterparts. How sure are you that the CGM chassis would be tweak free? The TC3 has been out for a couple of years now, and I frequently see on the forums that the TC3 chassis will tweak because of motor heat, and stay tweaked. The CGM and TC3 might not be tweaked because of a collision though.
