Hi Paul,

You can't go wrong with the Whirlwind. Also, something to keep in mind, the WW comes with a ready to use spinner system. It is done!!!
 
I tried to keep the weight forward with a
Sensenich prop on my 7A. I also used
their metal spinner.
My W&B worse case has my baggage limited
to 80 lbs.
If limited baggage is a problem, you may
have to add some more weight up front.
You can easily run some 'what-if' W&B numbers.

The whirlwind GA prop looks awesome. It's the same blade as the 200RV. It's a tad spendy compared to the sensy but it has it's benefits.

What engine are you running? If you are running the 150/160HP 320 the sensy has RPM restrictions to keep in mind. The 180HP sensy does not.
 
Does anybody have the Whirlwind GA installed on an RV-4? I was just wondering what your impressions are, what pitch you're using, and what kind of performance you're seeing?
