At Oshkosh Mark Kettering indicated that a Sonex (don't recall if it was a Legacy or B-model) was in the process of hanging the engine. Sounded promising that they would have a FWF package available in the near future. I've been trying to get a hold of Mark via email but no response yet. Anyone hear anything?

Thanks very much, those pictures do a good job of showing his approach. Comments:
- It's surprising to see the engine that far forward, though you've explained the rationale. I can only imagine where a (lighter) Aerovee would have to be. At >some< point there would need to be additional tail volume to offset the added area forward of the CG.
- There's a lot going on under there. All the liquid-cooled installations make the air-cooled installations look clean and simple.
- I wonder how performance would be affected by a simpler exhaust setup. It looks like they've done a good job of folding everything into a compact space, but the weight and under-cowl heat from those long-ish pipes adds up.
- Lots of people have had good things to say about the look, fit, finish of the Aeromomentum components, and these photos appear consistent with those reports.

Thanks again.
