If I wanted a 180 HP plane...it'd be an RV. Plain and simple.
I know they're more expensive...easily the cost of three or four Cessna 150's...but wow.......
My 150/150 Tailwheel plane is one of the most mild-mannered planes I've ever flown...nose wheel or tailwheel.
Even other's that I've let fly mine agree, it's extremely docile.
Do I secretly wish for more speed? It ain't a secret. I think we all do. I do maintain that it's an awesome balance between fun, speed, utility, and cool-factor.
We've effectively totally hijacked the OP's thread...and we don't know how determined he is to get a 180 HP taildragger.
Good luck in your quest...
