If you enjoy RC Glider flying but don't want the worry about huge
experience, weeks or months of building or down time for repairs our Martin Wing
is for you. Other than the elevons (control surfaces) the Martin is constructed
of foam. It arrives as two wing halves that are easily glued together and the
cutouts, that are necessary for electronics etc, are already done for you.

The Martin is built so that even if it falls out of a 60 foot tree it would
simply take a piece of tape to ready it for flying again. Thanks to Doug Martin
we have a wing that will ridge soar in the lightest conditions, out thermal, out
glide, out sink any other foam wing and if that doesn't matter to you just have
fun.
