"AeroModeller" magazine is almost certainly the oldest-established model aircraft magazine remaining anywhere in the world, having first been published in 1935 and remaining in publication ever since apart from a brief hiatus in the early part of the present millennium while things were sorting themselves out a little. Now, with Andrew Boddington at the helm as Editor, this iconoclastic British magazine is very much alive and well, going from strength to strength. It's published from an address in Totternhoe in Bedfordshire, England, and is available by mail order around the world.
Just so that we're clear, the magazine is very much focused on aeromodelling as it was when it was a hands-on skill-based hobby as opposed to the bought-in-a-box push-button activiy that it has become in recent years. Although electric power is covered, there is a strong focus on I/C-powered models as well as on the engines themselves. There are historical articles on model engines as well as tests of current models by the likes of Maris Dislers and your truly.
If you're one of those (like me!) who still likes I/C powered modelling and still views aeromodelling as a hobby rather than a leisure activity, then there is no better magazine on the market today. I view it as a monthly treat! Check it out at the official web-site.
