Hi all, just wondering if anybody has had any experience with the OS MAX 21 VZ-R version II 1/8 on road engine. I would like to know the good and the bad sides of these motors. Do they have the speed of the Nova based enigines. I'm only new to 1/8 and would prefer to keep the budget down a little. Please any comment are welcome.

Hello from France, i own this engine and I like it.
For the price, it can compet every engine and it's reliable and easy to tune like always with OS.
Here's my article for french website.
