Whirlwind propellers sold to Hartzell
Got an email today telling me effective 1 September my next phone call to Whirlwind will be routed to Piqua, Ohio, home of Hartzell propellers and its newest acquisition, Whirlwind propellers. All manufacturing and management will now be in Ohio. I imagine they’re clearing their desks out back in California. Oh, and also effective 1 September buying anything from Hartzell for my Whirlwind prop using my credit card will cost more. Yay!

Thanks for the update. Upside for me Piqua is close. Downside it probably won't be cheaper.

My experience with Whirlwind in California was great.

Hi Jim,
Finally made a real second flight a couple of weeks ago and found a few changes that needed to be made. First pulled the custom throttle and went for standard panel mounted one. It is still a hybrid so some head scratching continues. Cannot do without elevator trim, so ordered and received Ray Allen/Zenith system from Zenith. I will try to install it this week. Third thing , the plane was not performing as expected in cruise, barely getting 60 mph w engine over speeding. Whirlwind prop set at factory recommendation (17 degrees I think). I believe you have the same prop as me, maybe not same length and you are running 80 hp vs 100, but do you recall what you set your prop at for STOL Ops.
