After upgrading from a Model 3 Rotax 582 to a Model 5 912ULS, the only complaint I've got - is engine noise in the cockpit. When that 912 cranks over about 4900 or 5000 it gets loud enough my Zulu's even have trouble drowning it out. Any suggestions on effective noise dampening? I have no noise padding anywhere.... a thin sheet seperating the firewall
padding and my feet, but none on the belly under my feet or anything - figured it wasn't doing much so i pulled it last annual
