On one of these sites I have seen a picture of a Sonex without its cowls on showing the Jabiru fibreglass baffles fitted which looks neat. Has anyone experience of these, please? Would appreciate any information, particularly comparisons from anyone who may have tried both.

The Bristell production aircraft also uses fence baffles on their Jabiru installation. There were some better pics floating around but I cant find them now!
Anyway here is the link to the Aussie distributor [urlhttp://andersonaviation.com.au/][/url]
Fibreglass ducts have been used by Lynn Jarvis on his 2200 powered Sonex since late 2003/2004. His head temps run quite cool, around 120C (from memory) after some experimentation.

The early Jabiru fibreglass baffles did require some radical trimming to fit within the cowl, particularly the RH side.
