Peak of Flight Newsletter #522:

Perfecting Competition Rockets in RockSim 

Peak-of-Flight Newsletter

A casual or average hobbyist can use RockSim to design rockets and acquire a whole bunch of data and insights about that rocket before they even begin building it.

An experienced user would be able to take that rocket file, and through a series of tests, create a rocket file that would produce the necessary data to allow you to make on-the-fly adjustments to your rocket and accurately predict the outcome.

This is an essential process for competition conditions, and you should know it if you are looking to leave your stamp on the field. In this issue, we'll list the steps you'll need to take as you design your next competition rocket, so that you'll get that winning model done in the quickest amount of time.

Read the rest of this week's article, either on a downloadable PDF for printing out, or on our website (great for viewing on your phone)!

Threaded Rod Motor Retainer

Threaded Rod Retainer

The threaded rod motor retainer system is an inexpensive and versatile way to restrain the movement of rocket engines.

Pioneered by Cosmodrome Rocketry, this style of engine retainer is noted for its simplicity and ability to be used in any size rocket. It can even handle up to a three engine cluster.

Clustered Rocket Display Stand

Clustered Engine Display Stand

Rockets that have cluster motor mounts are harder to display because they don’t balance properly on stands intended for a single central motor. These new display stands (sold in sets of two) plug into the individual motor tubes of the rocket and allow the weight of the rocket to be spread over a wider footprint and the rocket stands more securely on your shelf. They can be used on any cluster rocket, no matter how far the motor tubes are spread apart. Each stand can be rotated independently too, just in case one motor tube is slightly askew. Available in three sizes:

18mm Stands
24mm Stands
29mm Stands

AeroTech Mega Initiator

AeroTech Mega Initiator

The Mega Initiator is the scaled up version of the Initiator, also by AeroTech. This is a significantly larger rocket than it's predicesor, and is built with high-power components. This rocket stands 5ft tall with a 4 inch diameter and can house a variety of motors in 54mm, 38mm, and 29mm motor sizes. This means the Mega Initiator can safely fly on a ton of motors with impulse levels all the way from G through K.

29mm Fin Alignment Guides

Semroc Stellar Arrow

For those people that were looking for a fin alignment guide for the Aspire kit, we now have them available. It is the new 29mm fin alignment guide for thin-wall tubes. they are designed to make applying fins easier and more accurate than ever, and it is available in both 3 and 4 fin configurations.
See our 29mm 3-fin guide
See our 29mm 4-fin guide

Motor Mount Adapters

Semroc Stellar Arrow

Easily adapt a rocket kit to house a variety of motors using the new line of motor mount adapters from Apogee! These adapters are designed to adjust a 29mm motor housing to a 24mm. We've also released adapters for 38mm motor mounts (down to 29mm) and 54mm motor mounts (down to 38mm).

T-LOC

Semroc Stellar Arrow

The T-LOC, another high quality rocket from LOC Precision, has a few features that really separate it from the pack. It's short and stubby, with a lot of drag in comparison to other rockets that utilize the same motors. These may not sound like "features", but they do offer some capabilities you might not see in other designs.

Customer Comments

Thanks so much. After many years of model rocketry, I decided to get into High Power rocketry! Luck was on my side, while locked down in quarentine, I wondered onto your site. I purchased the Zephyr, I couldn't be happier. The build was super straight-forward. The online assembly video's were amazing.

Since I have some time before my "test flight" I decided to buy some smaller rockets for my son and daughter. Again, straight-forward ordering process, tracking numbers available the next day.

To anyone who stumbles on this site: Model rockets are the ideal way to spend fun, yet educational time with your kids, especially important with all that's going on with this pandemic.

I need help with generating the bi-weekly newsletter articles since it takes a lot of effort to put them together. And I'm willing to pay big bucks for your help.

So ask yourself, are you looking to earn some extra money?

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.
