Apogee Rocketry Workshop #335:

Finding the Optimal Delay for When to Stage Rockets

Advanced Construction Video

A common question we get is about "when" to stage a model rocket. Do you want the upper part (called the sustainer) to ignite immediately after the burnout of the booster motor? Or do you want it to coast a little way before igniting the upper stage? The answer is that it depends on the atmospheric conditions. In this video, you'll see how we figure out the best time to stage using the RockSim software.

OOPS - WE GOOFED!! It has been so busy at Apogee lately that we forgot to send this video last Tuesday. So we are catching up with a special Wednesday email to get back on track. Thank you for understanding, and for keeping us so busy!

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

When building a high powered rocket, I used to have visit at least 5 websites to get everything I needed... and I would still forget things. After shopping with Apogee I can get everything I need in one place. Not only that but at the bottom of page it will show me what others have bought when buying this exact part, and I will remember that I need that as well. It sounds nuts, but nuts is shopping at 5 websites paying shipping at all of them, and at the end remembering your forgot the parachute protector or Kevlar line. Apogee has that too!!!”

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.
