WHy is it a few people who races 1/10 touring cars seldom uses OS engines like the OS TR. What they usually fit in a Serpent710, R40 or an MTX-3 is a Novarossi, Sirio or an RB engine. Is the OS TR engine really outperformed by its Italian counterpart in all aspects? or is it just they prefer newly released engines? Im currently trying to bring life to a Kyoho V1RR and an OS TR engine to power it. With this, will my car be able to give a fight with the big guys in terms of speed and handling? Of course driving skills is a different story.. thanks...........
