anyone know of a site or magazine that has dyno charts of an os 50 hyper? maybe even with different pipes?
TIA

No but 17000 is supposed to be its sweet spot. Thats where I run it in both my Raptor and EVO

From testing @ different head speed with a zimmerman and Hatori I think 17000 is the very bottom. I run mine up 17800 and would run it faster if I thought the heli and engine would take it.

thanks for the input guys. i'm still learning, but looking ahead. trying to plan what muffler/gear ratio/blade length will be best for my rappy 50 after the titanium parts (longer boom, allowing 620 blades) become available.
