Wingleader/Red Kite is preparing to lauch a new (monthly) magazine for 2019. Every issue will be available for FREE in pdf format (but with ads) but also in physical (3 issues at once but without the ads). More information here and about the crowdfunding campaign (I hope not a scam like the last one I posted on this very forum...) to launch it :

Not sure if the "Limited Edition Launch Issue" will be available in pdf.
