Apogee Rocketry Workshop #336:

How to Insert and Restrain an Igniter in a Composite Motor

Advanced Construction Video

I was at a launch a few weeks ago, and a modeler that had never used a composite motor before came up to me and asked how to insert and then keep the igniter in the motor so it wouldn't fall out when the clips were hooked on the leads. This seems to be a common question, as I've shown lots of people this same information over the past few years.

In this video, I'll show you three ways to hold the igniter in the motor, which seems to be the main concern that people have with composite propellant motors. Hopefully, this will help us all to experience fewer misfires at launch.

Zephyr Jr Rocket Kit

Zephyr Jr rocket kit

The Zephyr Jr rocket is a 1/2 scale rendition of the famous Apogee rocket that so many people use to get their L1 Certification. This is an "everyday" rocket that can be used whenever you feel the need for speed. It is based around the BT-70 size tube, and uses simple construction techniques like surface mount basswood fins. It comes with a beautiful 5-to-1 plastic ogive nose like its bigger brother. You'll find that this lightweight rocket flies great on 24mm diameter rocket motors.

Klima ME-163 Rocket Plane

Me-163 Rocket Plane

The legendary Me-163 rocket plane comes to life as a real model rocket that you can control. From Klima and imported from Germany, this rocket is fast, it's maneuverable, and it is a lot of fun.

This is a radio-controlled rocket that you control going up and as it glides down to the ground. It is Skill Level 5 for the challenges it has in construction and in flying. RC radios, servos, and transmitters are NOT included. We recommend it only for the experienced RC-rocket pilot that is looking for something fast and challenging (MORE ON ORDER).

Small Parachute Swivels

Small Parachute Swivels

We now have two new small sizes of low-friction ball-bearing (barrel) parachute swivels in stock. This is a 21lb swivel for tiny rockets (up to 1 pound), and a 100lb (rated strength) swivel that we'd recommend for rockets that are up to about 4 pounds in weight. With this addition, we have swivels for nearly every size rocket you'd be flying this year. Check them all out here!

Estes Antar

Estes Antar Rocket Kit

The original Antar rocket was created in 1951 by G. Harry Stine, the founder of the National Association of Rocketry.  This is a faithful reproduction of that display model, and is actually intended to fly. Based on a BT-60 size tube (1.637 inches diameter), the Antar is a great model if you'd like something a little different looking and that is somewhat bigger. But it still flies nicely on 18mm diameter rocket motors.

Customer Comments

I build a lot of rockets. And over my life have built well over 100 rockets. Currently I have ready to fly over 25 high powered rockets equipped with dual deployment, GPS tracking and several with full redundancy. I have purchased rocketry parts from probably every supplier, but nobody compares to Apogee Components. From the vast inventory available, to the fact that the people at Apogee Components go the extra mile to assist you in finding what you need. Additionally Apogee Components offers free of charge an incredible education program that nobody offers. I highly recommend this company as a company that stands apart from the rest. A company that is a pleasure to do business with that understands this market. Well done Tim!”

I'm now actively seeking writers for articles to appear in this newsletter. And I want unique and cutting-edge articles because that is what you want to read, right? I realize this, so to get articles from outside writers that have the same level of quality, I'm going to have to pay a lot of cash to make it worth it for them. So I've come up with a compensation package where I'll pay up to $350 for good how-to articles.

Are you a writer, and does that interest you? That is a lot of cash! Far more than you'll get by writing for other magazines. And with over 23,000 worldwide subscribers, if you write for the Peak-of-Flight Newsletter, you'll gain a lot of notoriety. Writing for the Peak-of-Flight Newsletter is a great way to show off your rocketry projects and your technical expertise, at the same time as helping out other rocketeers. Imagine how great you'll feel knowing that you made a difference to the hobby.
