I discovered something strange today: the cowl-inlet on my newest RV-7 is actually alittle bit SMALLER than the inlet on my oldest -7....
Here's a couple of pics of the oldest cowl:
The height of the inboard edge is about 10 cm, and the height of the outboard edge is about 8 cm.
Here's a couple of pics of the newest cowl:
The height of the inboard edge is about 9 cm and the height of the outboard edge is about 7 cm.
When you look at both cowls at the same time, you can see the difference:
The oldest finish-kit was bought from Vans early in 2007 and the newest was bought late in 2010.
Does anyone have any idea as to why the cowl openings got smaller? Better cooling? Less drag?
Both -7's have fine engine temps etc, so I'm just courious if anyone knows anything about this?
