Ok, that sounds fast and also you should have done some serious modifications to get in the 6s pack. Whats your flying weigth, above 800gr.?

I wrote that you'll get the best result with a skirt of 10 lines, 0,2mm first layer heigth and then 0,1mm. Also use 10% rectangular infill with 3 outlines.
I've printed about 20 of them and got with this setup the best result between stiffness and weigth. The weigth should then be around 5 gr. per winglet.
