Quest Falcon

15-Minute Cure EpoxyEver want a quick build rocket kit, that you can put together in under an hour, and just want to blast it to the moon? The Quest Falcon rocket is just such a bird. With the one-piece plastic fin unit, that simply slides over the tube, this rocket can be assembled in no time at all. Plus it has a 24mm diameter motor mount, so you can load it up with F motors that will put this thing out-of-sight.

Quest Sport

15-Minute Cure EpoxyInexpensive, FAST, and super-simple to build, the Quest Sport rocket is a nice choice for a first time rocket. It can be assembled in under and hour, and it just begs a big 24mm diameter motor to send it to the clouds. Get one today before they are gone.

15-Min Cure Time Epoxy

15-Minute Cure Epoxy

The Mid-Cure 15-min Epoxy from Bob Smith Industries, is a really nice epoxy for general purpose use. It cures reasonably fast, hardens very clear, and is quite strong. The extra setting time (verses the typical 5 minute epoxies) allows time for air bubbles formed from mixing to come out of the epoxy before it sets up and allows some additional time when you are doing a more complicated joint or gluing job. Comes in a convenient 4.5 oz bottles that allow you to mix a little, or a lot.

Make Carbon Fiber Tubes

Make Carbon-Fiber Tubes

Here is an extensive and detailed video course on how to make Ultra-Lightweight Carbon-Fiber Rocket Tubes. They're so light, they give you an unfair advantage in competition. These are the ones that my daughters, Allison and Ashley used in Romania last September at the 2021 World SpaceModeling Championships. Allison was part of the senior Silver Medal winning USA team, and Ashley took home the Bronze Medal in the Jr. Division. The girls were taught how to make their own tubes, so if they can do it, so can you.

The training course consists of 5 hours and 42 minutes of video instruction, covering everything I know about how to make a successful tube with a glass-finish using a 2-piece mold. It even includes all the secret techniques and materials, and where to buy them, including where to get the 2-part mold.  

This course is on the Udemy website, not at Apogee Components.

 

RockSim Live Training - Every Friday

 

Launch of the Week

It didn't go into orbit...

My simulation today shows the Quest Falcon rocket powering its way to almost 3000 feet on an F39 motor. I just wanted to see how far I'd have to walk to get it back. As you can see, it almost made a splash landing. 

This was launched from Jackson Michigan Rocket Club's field near Manchester. What would you do to fly this rocket on this motor and have a better odds of getting it back?

Customer Comments

“I’m a relative newcomer to rocketry and what made Apogee’s site stand out to me was the sheer amount of tutorials and help. There are countless videos on the site and on YouTube that cover all aspects of the hobby. Each product has a ton of information and tips, even going so far as to describe the different propellant effects for each motor! Apogee has played a huge role in my education for rocketry. In addition to all of the information on the site they also include helpful DVDs with my orders and always get my shipments out fast and to my door quickly. Tim and his team rock and I look forward to continued business with them for a long time.”

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.

If you're interested in writing, see the guidelines on our site.
