I’ve recently flown a version of the Citabria with nearly 180 horsepower. The standard version I fly is down around 115. The extra bump doesn’t seem like much on paper, but man, it really gets the plane moving in a hurry. I can climb far faster than I’m used to, stay at altitude, and cruise at max speed no matter what. And before you ask, no it doesn’t burn much more avgas than the standard version.
The downsides of this new plane are: it’s more expensive to rent and I am now “behind the airplane” a lot more than I used to be. More things for me to learn and aware of on the flights around the area, I suppose.
