Hi,

Try to convince them that the db`s fall way off once airborne, unlike the piston bangers. Last Saturday there was a club member at our field with a db meter. We know that a turbine in the pits at full pipe is 100+ but on a full speed low pass over the centerline with my P-120 powered A-4 the db reading was 79. Throttled back its much quieter.

Vin...
