I'm just asking to see if its possbile to even reach 140 and what kind of watts is needed. Heck the record is 134.4mph and that's with a purpose built RC that looks like a spaceship and is lightweight. This heavy and big monster buggy with a buggy body that is not aerodynamic can't be easy to reach those speeds...lol
I will take some pictures tomorrow of what will be the body for my propose built speed car. The body will have the famous tear drop design. I will also be designing a very nice active system to keep my car on the ground. The only problem is finding the time to do all of this .
