CMB vs OPS

[Thomas Ljungström]

Is this the engine that are to break CMB's dominans? Nothing wrong with CMB but it sure would be healthy for the model boat sport to have more engine alternatives.

What do you guys think?

Yes let´s hope it will be a competitive engine so cmb will have some to race against..
