The classic V-2 kit with a balsa nose cone and tail cone. Uses heavy-wall body tubes, so it is big-motor ready. Includes an ejection baffle, so it doesn't need any wadding.
Capture a Piece of Rocketry History!
Large size of the kit.

Capture a bit of space history. The V-2 rocket was the first large liquid-fuel rocket to be put into mass production. The reason was that it was reliable and big enough to carry a large payload.

The U.S. Rockets V-2 is 2.5 inches in diameter, and over 20 inches long. It is made from heavy-wall body tubes, so it can fly on big, high-thrust rocket motors.

The rocket features a built-in ejection baffle, so you don't necessarily need wadding. It also comes with a balsa nose cone and tail cone (called a boattail). This is an easy to put together rocket, and you'll enjoy flying it often. It is always a crowd pleaser.



Why Is This Classified A Skill Level 3 Kit?
Ejection baffle assembledThis rocket is slightly challenging to build and fly for several different reasons, and is rated as a Skill Level 3 rocket on the Apogee Components complexity scale.

First of all, the instructions are not very detailed, and use simple line drawings where photographs or 3D drawings would have been better. Secondly, the part nomenclature from US Rockets is different from other manufacturers, which doesn't simplify things at all. You'll want to look at the images here, plus the RockSim design file (elsewhere on this page), and the images on the U.S. Rockets web page for some clarifications.

But the biggest reason this is a skill Level 3 design is that you have to cut slots into the engine mount tube to make the engine baffle as shown in the photo here. This requires a steady hand while using a sharp hobby knife.

You also have to glue the ejection baffle plate to the front edge of the tube, so that it fits perfectly into the body tube of the rocket. The instructions are a little vague on how you would do this.

THere is a video that will guide you through the steps in cutting a slot in a body tube:

U.S. Rocket 2.25" Diameter V-2

The U.S. Rockets kit 2.25" diameter V-2 comes in a bag that is packed with parts. All the parts are good quality, and you'll be pleased with them.


So many parts
Balsa wood Fins

Laser-Cut Balsa Wood Fins - The precision of the cut on the fins is remarkable. The edge matches the curvature of the boattail almost to perfection. So you'll get maximum bonding area when you glue the fins onto the rocket. That makes it incredibly strong.

These fins have perfectly square edges so it's easier to get them aligned. They can easily be airfoiled for a significant improvement in altitude.


Premium body tubes. The smaller spiral grooves result in reduced finishing time. These body tubes are somewhat stronger and a little thicker than the tubes used in most single-engine rocket kits. That means this rocket can take the pounding of a high power rocket motor.

Ejection Baffle - The kit includes a baffle disk to protect your parachute from the heat of the motor's ejection charges. But for extra protection, we also recommend adding wadding or a parachute protector for even more heat reslilence.


The kit comes with a 15 inch mylar parachute. To be honest, this is something you'll probably want to swap out when you go to fly th erocket. A 24" nylon cloth parachute would be a good upgrade to this kit.

US Rockets V-2 Recovery Hardware

Stout Hardware - The rocket kit includes an Kevlar® shock cord, 1/4" diameter launch lug, and metal screw eyes.


The nose cone is big. And it is balsa wood. That means it is light weight, and easy to finish using standard modeling supplies. You also get the balsa wood tailcone that has been cored out to accept the 24mm engine mount tube. These come from Balsa Machining Service, so you know the quality is top-notch.

US Rockets V-2 Instructions

The 4-page assembly instruction sheet will guide you through the construction of this model. Where you might need a little assistance check out our how-to videos, and these issues of our Peak-of-Flight Newsletter:



There is an extra booklets that come with this rocket.

  • Advanced Information Report on Motor Installation. This book is a bit dated, since a lot has changed since it was written in 1984. We recommend the book "Modern High Power Rocketry 2" as a replacement for learning the clustering techniques in high power rocketry.

    The motor installation is pretty easy on this kit. If you don't want to friction fit, you can get an engine retainer.

Note: These motors (HAZ) are shipped with a HAZMAT fee of $28 on top of the standard UPS/FedEx ground shipping costs. (Learn More about HAZMAT Fees). These motors are non-returnable due to shipping regulations.

If you are purchasing an age- or certification-restricted motor, please email or fax us a copy of your ID, or NAR or TRA membership card as soon as possible so we can get your order shipped promptly. We will keep not of your status on file, so you only have to do this once. If you are not certified, please see our information page for additional details on membership and high power certification.


18+ - You must be at least 18yrs of age to purchase ths motor.

Rocket motors are sold separately from the kit. For more help in selecting rocket motors, see our video tutorial. If you're unsure, start with the "First Flight" recommendation or the one with the lowest altitude, then go up from there.

For other motors that are not tested or not listed here, download the V-2 2.25-inch RockSim file and load it to see if it will work in this rocket kit. See also Technical Publication #28 for guidance on selecting appropriate rocket engines other than those listed in this chart.

What is a RockSim Design file?

The RockSim software gives you a lot of information about the flight characteristics of this rocket: how high, how fast, where it will land, how will it react to wind, etc. The "design file" is intended to save you time. All the parameters (size, shape, weight, fin design, etc.) of this rocket have already been entered into the RockSim program, and saved as an electronic database file. You can just open it up in your copy of RockSim and start loading different rocket motors to run launch simulations. It's fun and educational to see the rocket zoom skyward, even before you built it. For more information about RockSim and to download a FREE 30-day demo version, click here.
