Rotax 912 cylinder temps

Recommended Posts

I can do next time out at the field. 

 

I suspect I know what to do now however.  Just need to dedicate the time to it.

 

I guess this is the drawback of using a non factory fully supported engine before others have fully paved the way.  Hopefully I can help others later if they go down this path when I have the bugs sorted out.

Before the opportunity (that I could not refuse) came up to purchase my Zephyr, I was very keen on going down the kit built Sonex/Rotax 912 ULS path. Did a lot of research from (aged/imperfect ) memory powering a Sonex with a 912 has been done quite a few times - someone out there has been down this path and may be able to advise.

 

If all else fails I can send you photos of the Zephyr radiator & oil cooler layout and dimensions of the  air inlet/outlet ports. I have never had an overheating problem (touch wood). In fact I reduce my outlet in winter using a shaped and stiffened aluminium sheet to speed engine warm up and maintain a half descent temperature during cruise.

Nah,,   I flew it for 107 hours but this half life Rotax came along at a good price so I swapped it out... unfortunately I seem to like building as much as flying so I'm a bit if a repeat offender...

All good. The Sonex community is rather small and we all corrospond frequently.  If we all go back to the start of this thread basically all I was after was real world temps that other Rotax owners see in flight and in climb... 

 

Thanks though for the replies.. it all helps
