See the video below for help in selecting rocket motors. Rocket motors are sold separately from the kit. If you are unsure which one to pick, start with the one recommended for the First Flight, and then another for a more impressive launch. Most motors listed in this chart are available through Apogee Components. For other motors that are not listed here, download the RockSim file 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. If you don't already have Technincal Publication #28, give us a call, and we'll be happy to let you download it free (you have to ask though).

The Jay Hawk from Mad Cow Rocketry is a great rocket kit to introduce you to mid-power scale models. This is a semi-scale model of the AQM-37A missile used by the U.S. NAVY as a high-speed target drone.
This model is perfect for modelers that like rockets that can stand up to a lot of punishment. It has thick-walled body tubes, plywood fins and centering rings, and a nylon cloth parachute. It also features through-the-wall fin tabs, so these fins are not going to let go if the rocket has a harder-than-normal landing.
The big size of this model will surely get you noticed. If that doesn't do it, then they will certainly hear the roar of the big motors that this rocket can easily accept. There is nothing like the throaty roar of a big engine to get heads to turn to see what is going up.
|
The Mad Cow Rocketry Jayhawk kit is pretty much deluxe in nearly every way. You can tell it was engineered by someone with experience building mid-power rockets. There are lots of laser-cut parts for precision mating between parts, and the thick wall tubes are stout enough to withstand big rocket engines and hard landings.
|
|
|
|
- Slotted tubes and through-the-wall tabs on the base of the fins: Allow for perfect spacing and exceptional durability
- Waterslide decals: Allow for a professional looking model while still giving it a lot of colors
- Thick-wall cardboard tubes: These tubes are meant to take a beating and survive some very rough landings. That means your rocket will last and last and last.
- 30" Diameter "Rip-Stop" Nylon Cloth Parachute
|
- Heavy-duty plastic Nose Cone: This nose cone is practically indestructible. You'll love the heft of it, as it feels solid.
- Kevlar® Shock Cord: Kevlar is stronger than steel and is very fire resistant. That makes it a very strong so it is a more durable anchor to keep the nose cone attached to the rest of the rocket.
|
|
- Fins Made From Plywood: Plywood is extremely strong and has a very tight wood grain, so it is easy to finish. Just spray it with sandable paint primer, sand it down smooth, and it is ready for paint. You don't really need to apply a separate sanding sealer, so it is quicker to prep for paint than balsa wood. Plywood is also stiffer than balsa wood, so it more durable and can take a lot of abuse from rough landings.
|
|
- Plywood Centering Rings: Designed to take a pounding from high thrust rocket engines
- Laser-Cut Rings and Fins: The precision cut of the laser makes the parts the perfect size and shape. This translates into a kit that goes together a lot faster and with less effort on your part.
|
|
|
- Drag-Reducing Balsa Boattail: The transition at the base of the rocket reduces drag so the rocket can fly higher in the sky
- Extra Stout Eyebolt: Used on the base of the nose cone so that the parachute can be attached. The rocket needs extra nose weight for stability, so beefy hardware can be used to make the rocket extra strong.
|
- Unique Nose Weight Compartment: Since the nose cone is solid balsa wood, adding nose weight to make the rocket stable is a bit tricky. Mad Cow Rocketry came up with a nifty way of doing this. It is a compartment (coupler with a bulkhead inside the aft end) that is glued over the shoulder of the nose cone. The nose weight (lead shot or sand) is poured into the compartment and then it is glued onto the nose cone shoulder. The compartment then acts as the shoulder and is inserted into the main body tube of the rocket.
|
|
- Nomex® Chute Protector. This is a fire-resistant cloth that takes the place of wadding in the rocket. It is attached to the shock cord and is reused for each flight. It gets a bit sooty after a bunch of launches, but can be cleaned off and used again and again.

What Makes This a Skill Level 3 Rocket?
|
This rocket uses traditional construction techniques you are familiar with from building smaller model rockets. It can be assembled using wood glue, and goes together in a straightforward manner.
However, there are three things that push it into the skill level 3 category. First, it is a bigger rocket that uses heavy wall tubes. While the tubes don't make the rocket any harder to assemble, it does require extra safety precautions when flown. Patience and aquired flying skills to know when NOT to fly are just as important as quality construction techniques.
Second, you will need to use epoxy to glue some of the components together. Epoxy can be messy and can cause an allergic reaction in some individuals. Always use caution when working with epoxy resins.
Third, this kit does not contain an engine hook, so you'll need to have a bit of extra skill when securing the engine for flight. Please see our education page for more information on holding motors in big rockets.
Another option (not necessarily required) is that you can order the Aero Pack Engine Retainers. These are useful on rockets that use the 29mm diameter reloadable motors and really give the model a professional appearance. And yes, they can be installed on existing rocket kits like this model.

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. Windows and Macintosh versions are both available.

What is expected when you launch your model rocket?
|
|
|
Are you new to rocketry? Do you think you know what happens when you launch your rocket? Now you can learn about the events that occur as your rocket is launched into the air. So when you launch your rocket, you'll be prepared and you'll be able to show off your knowledge to observers watching your rocket. This article also gives you links to other references that will give you even more background information about rocketry, so you can become a true rocket scientist and expert.

"My last order arrived mangled (USPS fault). The body tube was dented and you were kind enough to send out a replacement right away. Your service has always been outstanding. I especially like all the follow up emails making sure all is well. It speaks to Apogee's commitment to customer experience. Tim is spot on with regards to customer service winning loyalty. This is the reason I will continue to do business with you. Keep up the good work!" -- Michael Perez
