mounted the 4 on the leech but did not yet manage to have all 4 in desired position simultaneously. Managed to get 3 ok but always one in between flies out of formation.
With leech tells... That is the desired result. They alternate between flowing aft and hooking to the back side. Flowing all the time would indicate under sheeted. Hooking to the back side all the time is over sheeted. You want a little of both typically.
