RC Glider Nose Mounted Tow Release

Tow Release Mechanisms for R/C Model Gliders Offered in Three Models The 1.5-2.5m size range is covered by these three tow release mechanisms for R/C model gliders. Three models are available: 1. Just the release mechanism (8mm dia) 2. Tow release integrated into a 50mm long x 48mm dia nose cone 3. Tow release integrated into a 65mm long x 60mm dia nose cone The tow release mechanism is a "pin in tube" style release, requiring a length of music wire to act as the pin and run back to your release servo. They are designed for 1mm wire, but anything from about 0.8-1.5mm should work fine. I use this type of wire in my planes: https://hobbyking.com/en_us/push-rod-and-sleeve-set-5pcs-bag.html The mechanism works best with a loop of fishing line on the end of your tow line. To attach the tow rope, simply push the loop into the lower half of the tube, it will slide up the ramp until it hits the top of the tube. You can then close the mechanism so the pin passes through the loop and rests on the tube divider, locking the rope in place. These models are all designed to be printed in PLA without supports. I used 10-15% in-fill when printing mine and they came out really strong.
