WTF is all this crap about people being worried about cantilever wings clapping over the top???
Does anyone stress about a warrior or bonza?
Guess what? NO STRUTS!
If I recall the C210 had a Turb Pen speed of 119kts?
As always, check specific model speeds in the POH.
1978 C210M 119 KIAS @ 3800lbs
1979 C210N 125 KIAS @ 3800lbs
