Any tips about how to reduce the noise from the Vibe?

I'm using sound proof sheets on the inside of the canopy and it helps abit.

shorter blades equate to more loading on the blades and therefore more momentum and high inertia against getting blown around. you will lose a bit of auto but it's worth the trade.
Also yuo need to consider your flybar ratio; if the heliat a hover goes into the wind (hope I've got this the right was around!!!)sorry if not. your flybar ratio is too high and vice-versa

as always $0.02

Please feel free to correct and diagree!
