Does anyone know anything about the Novarossi RS 8 crono or the plus 21-8t. I did some searching and didn’t come up with anything on the plus 21-8t and I saw where someone said the crono was a fast engine. I wanted to buy another two engines and found these at decent prices or I may just get a Rolling. They would be going in a truggy and buggy for bashing. Any information would be helpful. Thanks
