We had a guy running a 1/8th electric buggy conversion today running 4s with the Mamba Max with a fan on it. He was running 6 minute heat races and the speedo was a 140 degrees. Not that the Mamba Max was desgined for this but damn this speedo is tough.
The guy knows its not designed for this and he said if he did burn it up he wouldn't be made about it. He is waiting for the Monster Max but in the meantime he said he was just going to keep running it and having fun.
