What is on my mind this week is that I've been looking at the number of subscribers to this newsletter, and I've noticed that we've hit a plateau in the number of new people subscribing. So I'm going to throw in a new incentive for all subscribers, which includes you too. Starting next week, we're going to do a weekly drawing for a free rocketry kit!

Since you are already subscribed, you only need to do one additional thing — read the Tuesday emails and interact with them. "Interact" means you have to click on at least one of the links (except unsubscribe).

That's pretty easy, right? Just be a subscriber (which you are), and click on the link(s) to discover more information from Apogee. Let your friends know that they can subscribe too, so they have the opportunity to win our weekly drawing.

The first kit will be the Apogee Air Mail rocket, and the drawing will be held next week Tuesday. We'll notifiy the randomly choosen subscriber from those that interacted with next newsletter by the end of the week.

This past Tuseday, we released the third video in our series on building the TTV rocket kit. In this step of the construction, we are taking the short coupler, splitting it in half and turning it into a long coupler that the ebay sled is attached to. The critical part of this step is that the curved side of the two couplers must be straight so the finished ebay will slide easily into the body of the rocket.

Swingshot Rocket Glider Officially Released

We officially released the SwingShot RC glider from J&H Aerospace this past week. Since it is RC, you can fly this rocket back to your feet so you don't have to retrieve it. It is also a swing-wing glider, which means it folds up for the boost phase, meaning you get a much higher altitude than a fixed wing rocket glider. You can fly this rocket on A-C motors, or if you're really daring, you might put it up on a 18mm composite D motor for some really sky-high flights.

Only a few days left! - Rocketry Tool of the Month - Digital Caliper

Our July Tool of the Month is a digital caliper. If you're going further in rocketry, you'll absolutely need a caliper. When you're doing things like designing your own rockets, you'll be constantly measuring components. Say for example you find a tube that you want to use to build a rocket. The first things you'll need to know are both the outer and inner diameters of the tube. You'll need that so you can find the appropriate rings to build the motor mount that will fit into your rocket.

You'll also need to know how long the tube is, and maybe you'll even need to make a depth measurement, such as how far into the tube to place the centering ring.
From precise measurements to user friendly features, the Carbon Fiber Digital Caliper is a must-have tool in the arsenal of any dedicated model rocketeer. Its affordability and exceptional performance make it the perfect companion for your design and building endeavors. Elevate your model rocketry projects to new heights of accuracy and craftsmanship with our Carbon-Fiber Digital Caliper. Order yours today and embark on a journey of precision engineering!

To get this caliper for free (a $11.95 value), just purchase $75 worth of Apogee's merchandise and add the coupon code at checkout on our website. This offer only lasts until July 31st.

What is Coming Up Next Week?

Our newsletter next week will have the second part to Tim's article about his learnings from the World SpaceModeling Championships that were held in the beginning of July in Texas.

Tim is also writing another one of his blogs called "Tim's Messy Desk." This one will handle a philisophical question about how he stays energized by rocketry after being in the hobby since the 1970's.

I'll see you in your email in-box next Tuesday.
