Selecting Motors for Optimum Altitude - Part 3

Fin Alignment Guides

Apogee has those inexpensive laser-cut cardboard fin alignment jigs that position and holds the fins while the glue dries. You get perfect alignment so your rocket flies straight as an arrow. This allows all the fins to be added at the same time in order to speed assembly. Now in four sizes: 13mm (BT-5), 18mm (BT-20), 24mm (BT-50), and 33mm (BT-55).

Adrel Altimeter

This small data-logging altimeter was designed specifically for the modelers that compete in international rocketry competitions (FAI). It easily fits into a 10mm diameter tube and weighs a mere 1.8 grams with battery (battery not included). It records 9 minutes of flight data (at 15 samples per second) that can be analyzed after recovery. It is the official altimeter used in FAI (international) competitions.

CP/CG Stickers

This year, we'd like to present a unique "sticker collection" as your Christmas gift to you when your subtotal on your Apogee order is $35 or more. The stickers feature a collection of CG and CP symbols, as well as other decorative items that you can use to dress up your rockets. Printed on self-adhesive vinyl, these stickers are the highest quality you'll find in the rocketry industry.

Offer Ends December 1: Just use the coupon code Holiday17 at checkout, and the cost of the sticker collection will automatically be deducted from the order total.

Midge - Two-Stage NAR Payload Rocket

The Midge was specifically designed for the NAR's "Payload Altitude" contest event, but it can be flown just for fun too. It is a two-stage, minimum diameter rocket for 13mm diameter motors that is just big enough to carry the standard 1 ounce, BT-20-diameter payload weight plus a small altimeter. The purpose of the event is to launch this weighty payload to as high an altitude as possible. The Midge accomplishes this because of its two-stage design that minimizes weight and its minimum diameter design. You'll be impressed by how high a small mini-engine can launch a rocket!

Mini-Condor Boost Glider

The Mini-Condor is a boost glider that uses 1/2A or A-sized rocket engines. It zooms upward by rocket power and then glides gently back to the ground after dropping off the motor and its streamer pod. The glider trims easily, so you'll get fantastic flight durations and earn yourself a step on the winner's podium for the longest flight! Easy-to-assemble parts make it perfect for beginners, and fantastic performance makes it a must-have for seasoned competitors. The NAR's competition rules have changed, and this kit will give you the winning edge!
