Day 3,140cm 13AR,-1 rear wing shim 40cm, 50 seconds, cruising speed, & high on mast

Testing plus 1 rear wing shim, didn't work. Tested 35cm rear wing, couldn't get it. The trick was -1 rear wing shim and the 40cm rear wing. It gave me enough stability to get going. The wing is wobbly from flex so i need to be more precise with my pumps to direct the energy into the wing. I also need to always pump down flat, any forward angle cause a loss of all lift.
