Hey guys I'm new to the forum.

I'm looking at a Pitts S-2E, and the engine is a Lyc IO-360-A1A with 260SMOH. The crankshaft flange has lightening holes in it, I am a little concerned it doesn't have the solid flange AEIO crank. The engine has a whirlwind 2 blade with a McCaully hub. Are those blades light enough for a "Lightened Flange" engine? This is my first aerobatic airplane, and I don't really plan on becoming an airshow pilot but I want an engine that will hold up. As far as doing snaps go, I would like to be able to do snaps but I don't have a whole lot of desire for Lomshavoks and other hard acro. I've read the problem is mostly associated with the heavier metal propellers rather than a lighter Whirlwind.

I have used the search button and read through some of the posts and read about the guys with the charger who had to get a new crankshaft because of this.


Thanks
