The new Jolly Logic Chute Release wraps around the rocket parachute and holds it closed with an elastic band until it the rocket descends to a chosen altitude. Then, using an electronic servo, it releases the band and allows the parachute to open. This allows simple motor-eject rockets to reduce the distance that the rocket drifts while on parachute, which is especially important for high flights, windy days and small fields. YOU control when your parachute opens!

Will it fit in my rocket?
We will learn more about specific rockets as we go, but as a rule of thumb the answer is generally “YES” if the rocket is greater than 40mm in diameter and long enough so that the parachute isn’t already tightly packed, “IT DEPENDS” for 38-40mm, and “NO” for less than 38mm.
Your parachute is ejected at the top of your flight as usual by your motor’s ejection charge, but Chute Release holds your parachute closed until your rocket falls to the altitude that you chose as the release altitude.
Here is a video from Jolly Logic showing you how to set the release altitude on Chute Release, and perform an easy ground test:
