sideslip PA28
There are sideslips and sideslips,
I think it depends on the bankangle and the fuelsystem.
I´ve tried some sideslips on our clubs PA28 yesterday. With 10 gallons of fuel in each tank. slipping with full rudder stopped the engine after 30 seconds....
Aircraft like the Piper Cub or the Citabria habe a small headertank where both maintanks are connected to. This makes their fuel system less critical to sideslips
