Tech Notes
   This is the 11/16" Muffler Extension for the #E3030, #843, & #762S mufflers

This Muffler Extension is a 11/16" spacer that installs between the muffler and the exhaust port on the side of the cylinder head. This results in the muffler being farther out from the cowl of the plane. One might elect to use one of the muffler extensions to keep the fuel residue farther out from a prized paint job or if the aircraft has a large cowl and the muffler isn't far enough away from the outside of the cowl.

This fits the: .35FP, .40FP, .35FP-S, .40FP-S, GMS .32

FEATURES: Natural aluminum construction

INCLUDES: One Muffler Extension Two 3x48mm screws w/.5 pitch threads OSMG6948 but can use OSMG6950

SPECS: Length: 17.5mm Width: 42mm Height: 10mm Distance between mounting hole centers: 35.5mm JAL 5/14/97 UP ir/jl JCT 2/13/04 updt tjt 050505 updt jbm 10/18/05
