Nice ! but I think I like the sound of the Moki more, it just has that real throaty exhaust note. I think you can get that sound with a larger exhaust collector!
Yes I think exhaust tube should be a little bigger to get that deep throat sound. But Moki doesn't make all the smaller size like UMS and price is better.
I Purchased one of these and plan to run it soon for the 1st time. What are the optimum props for this engine? I have a scale Axial 28x10, but realize I may need to go a little smaller.
