Here is a large semi-scale version of the aerial interceptor rocket that defended American and Canadian skies in the 1960's. This 2.6 inch diameter rocket flies on F and G size rocket motors.

Madcow Rocketry Bomarc Missile

The Madcow rocketry Bomarc Missile is one awesome looking rocket. Most big rockets look pretty plain, but this one is really different. It has a lot of fin area and extra details that are like eye-magnets that draws attention to itself.

When you walk out onto the launch range carrying this rocket, be prepared to be stopped several times. Your friends and other spectators are going to come up to you and ask to see it before you launch it. They'll want to fondle it and see all the detail that you've put into it. The paint pattern alone makes it worthy of inspection.

As they pick it up, they'll feel the heft of the rocket and they'll know that this is a tough bird. It even has a mean look to it.

This rocket is a semi-scale model of the long-range interceptor missile designed to protect against bomber airplanes that might try attacking North America. The real missile was developed by Boeing and Michigan Aeronautical Research Center, hence the name Bomarc. Its military designation is the Bomarc IM-99A. The rocket launched vertically using a solid rocket motor, and then switched over to ram-jet power to cruise at Mach 2 to its target.

On your first flight of this rocket, we recommend a short-delay for the ejection charge delay. The big wing and the ram-jet engines under the rocket can take the flight non-vertical. The short delay will allow it to deploy sooner if it does this. This is a heavy-duty rocket, so it can handle an early deployment with no problem.

Bomarc Launch

Here are a few photos of the rocket in an unpainted state. It is easier to make out details before the black paint color is applied.

The kit comes with a molded plastic nose cone that already has a red color. The simulated inlet cones for the ram-jet engines are made from balsa wood.

The wings on the Madcow Bomarc are built up using a combination of plywood and balsa wood. The plywood gives it strength and rigidity, while the balsa layer helps keep the weight down.

The tunnel that runs the length of the rocket is made from built-up sticks of balsa wood. This is probably the hardest part of the construction process, which is why this is rated as a Skill Level 5 rocket kit.

What Features Make This Kit Worthy To Be In Your Fleet?
Pre-slotted Body Tubes - The tubes in the kit are thick-wall for extra strength. They'll easily handle the high-thrust of big motors. The surface is slick and smooth, which makes marking lines on them easy. Finishing is also a breeze, since the spirals are tight and require little filling. The tubes are pre-slotted to make assembly more precise and quicker. Bomarc Missile Parts

Plastic Nose Cone - The nose cone is rated for high power flights. It is stout, with its thick wall. The nose cone is also pre-colored, so you don't have to paint it if you want to save time.

Two-Piece Shock Cord - The 2'6" portion that is attached to the engine mount is Kevlar®, which is stronger than steel, and can take the heat of the ejection charge. The upper 5 foot portion is nylon, which is strong to withstand the force of deployment and minimizes the chance of a zippered tube.

2.6 Diameter Nose Cone

1/8-inch Thick Plywood fins - A high-power kit like this deserves premium plywood, and that is exactly what you'll get in this kit. All the parts are laser cut for extra precision and to speed fabrication of the rocket.

Lightweight Balsa Planks and Sticks - This kit contains a lot of balsa wood for the details on the rocket. There seems to be enough to start your own lumberyard!

Plywood Rings

Balsa Inlet cones - The ram-jets on this rocket are purely decoration. But they look cool and are fun to build. The inlet of the ram-jets are topped with nicely turned balsa wood parts.

Large 1/4 inch Launch Lug - Because this is a bigger model, you'll have a larger lug on the side of the rocket. This is used with mid-power size launch rods, to stabilize the rocket so it doesn't sway in the wind prior to launch.

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.

Balsa Nose Cones

Water-slide Decals - These are real silk-screened decals that modelers prefer for scale models. Just soak them in water, and slide them off the backer paper into the proper position on the rocket. They go on fast, and you can easily reposition them.

Nylon® cloth parachute - You'll receive a 32-inch diameter cloth parachute that is extra strong for this heavy rocket.

Bomarc s Water-Slide Decals

Flame-Resistant Heat Shield - No recovery wadding is needed on this bird. Just attach the reusable heat-shield blanket to the shock cord, and your ready to insert the parachute.

Through-the-Wall Fin Mounting - Tabs on the base of the fins are slipped through slots in the body tube. This makes the fins extra strong.

29mm Engine Mount Tubes - This rocket is designed to handle mid-power size engines, like the G and H size rocket motors.

What Makes This a Skill Level 5 Rocket?

There is a lot of work to build up the tunnel (the large beam on the top of the rocket). This part is made from several pieces of balsa that are joined together and then shaped before attaching it to the rocket. It does take quite a bit of patience to get it assembled correctly.

The Bomarc is also 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 acquired flying skills to know when NOT to fly are just as important as quality construction techniques.

Tail View
This kit does NOT include an engine retention system. The manufacturer recommends friction fitting the motor into the rocket. We recommend something a bit different. 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 rocket kit.

5 of 5 Stars!Steven Schmoll -- 08/23/2012
I'm absolutely thrilled with this kit. I've been so busy, I haven't had the time to write a revue before now. My passion is building scale military rockets. I only have one thing I'd change in this kit. I'd make it in a 4" tube. I have to admit I'm not totally thrilled with the quality of the instructions. They leave something to be desired in that they require some guessing. I realize this is a higher level kit, but the instructions can be vague in places.

5 of 5 Stars!Scott Corliss -- 12/05/2012
I finished building and doing the paint out on my Bomarc just a few weeks ago. The kit is well rated at skill level 5, however with patience and attention to detail it came out as one of the most beautiful builds I've done. I did do some online research and found some very good diagrams and detail for painting which helped. I took the finished kit to our last Northern Colorado launch on December 1st and it had a lot of ooh & aah power. Because of the wind level I chose not to launch that day so have not got a report yet on flight character. However, if you are looking for a bird which will impress your friends just sitting on your prep table, this is the one!

The Bomarc also has some special sentimental value for me because a plastic kit version was the first model I ever built with my Dad back in about 1962. Overall extremely pleased with the total project.

Just an update to my previous review. Finally had good wind and weather conditions to fly this beautiful bird last weekend. The launch and boost with an Aerotech G76-4 was very nice. It made a slow graceful roll while climbing straight up and then as it coasted to apogee flattened into a brief glide on the big wing before a perfect parachute deployment. The key seems to be getting good alignment of the wing and tail and making sure there is adequate nose weight to get a stable CG. I used 10 ounces of weight in mine.

4 of 5 Stars!Terry Lawver -- 07/14/2015
Overall this is a really great kit and it will fly incredibly well if you pay close attention to the instructions. If I have any suggestions to make the kit a bit better it would be to clarify the instructions a bit more when it comes to the shaping and attaching of the upper conduit that goes over the wing and to the rudder. That part was a bit confusing but other than that, I had no real problems with assembly. That is the only reason why I gave it a 4 out of 5 rating. This really builds up to a very impressive model and is well worth the time and extra effort to make it right.
