Martinchu is right ...Helicopter International is very much about news ,much of it exclusive and betraying the contacts the editor has with the worldwide industry....it doesn't do arty-farty or long articles but fills a unique niche ,complementing Vertical and Rotor and Wing etc that go in more for features. It's the only decent mag in the UK now ,if you exclude the specialist Helicopter ife and Rotortoque.
For sales and training HeliData is the only helicopter fortnightly option I know of ...the advertising is on the web but the news side costs a lot...it digs behind the bland press releases but is really for those who want to know what their competitors and their own companies are up to !
