Peak-of-Flight Newsletter #555:

Model Rocket Replaceable Fin System

Peak-of-Flight Newsletter

Do you ever have the problem where you crunch a fin from a hard landing and you wish you could replace it right away so you can fly the rocket again? If you have access to a 3D printer, you can print some rails that will allow you to have replaceable fins. This article by Samer Najia shows you how to design your rocket so it can use this replaceable fin system.

Conformal Rail Guide
BT-70 to BT-80

BT-70 to BT-80 Conformal Rail Guide

Just in time for the new TARC competition. This special rail guide is specifically engineered to fit onto a BT-70 (56mm diameter) body tube so that the rail passes over a BT-80 (66mm diameter) tube. It is perfect for when the front part of the rocket is larger in diameter than the rear. And for extra strength, the mating surface conforms perfectly to the tube. Just a dab of glue will do to hold them on to the rocket.

Long March CZ-1

Long March CZ-1 rocket kit.

The Long March CZ-1 rocket is a 1/34 scale rendition from Aggressor Aerospace of China's first orbital rocket. This is a very challenging, yet rewarding rocket that can be used whenever you really want to impress others at the flying field. Flies on a cluster of four 18mm diameter high-thrust rocket motors. Limited supply, so order quickly.

Customer Comments

“I primarily purchase from Apogee because of its service. I really appreciate the fact that I can order from here during the week and have the item in hand within 48 hours. If I happen to order on a Friday it's here by the following Monday. Apogee carries a wide variety of aftermarket stuff that I can never seem to find anywhere else and that's important to me. I do a lot of scratch building. Furthermore, they carry those great obscure items such as large diameter clear body tubes just to name one. Ultimately it boils down to the service. The fact that I can buy a 29mm single-use motor and then watch a video on how to assemble it and then another on how to install the igniter, is a nice touch. I appreciate the Rocksim how-tos, and the other videos that provide tips and techniques that have been useful to me, as well as, the rocketry classes that I teach. Tim and the staff make this a personal experience and that's what keeps me coming back. I appreciate everything they have done for...”

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.
