Collapsible Bungee Tow Hook

August 2014

Introduction

After breaking a few tow hooks on my EPO Foam FPV planes, I came up with this collapsible tow hook. It requires a rectangular hole be burned (use a soldering iron) in the foam about 1/3 the distance from the wing spar to the nose. Then glue it in with Beacons FoamTac. Here are the parts:
