On February six, 2018, the SpaceX visitor thrilled the world with the launch of the outset Falcon Heavy rocket into space carrying a Tesla roadster convertible. The Falcon Heavy has the highest payload capacity of whatsoever currently operational launch vehicle, and the fourth-highest chapters of whatsoever rocket ever built, trailing the American Saturn V and the Soviet Energia and N1 moon rocket.
The Falcon Heavy is derived from the Falcon nine vehicle and consists of a strengthened Falcon 9 outset stage as a central cadre with ii additional first stages as strap-on boosters. Each booster is designed with landing legs then that they can exist recovered and reused on future launches.
The Dr. Zooch Falcon Heavy was originally released prior to the first launch of the real rocket on which it is based. It uses standard 24mm diameter tubes for the core and strap on booters, and a 33mm tube for the payload. The rocket uses traditional rocket materials, then if y'all've built a number of other rocket kits before, this one shouldn't be out of your wheelhouse even though it is classified every bit a Skill Level iv challenge rocket.
What makes the Dr. Zooch kits unique is that they often feature what are called "flame fins" for stability. The real Falcon Heavy rocket has 9 liquid propellant rocket engines in each of the three segments of the vehicle. These tin can be throttled and gimbled to stear the rocket. On a model rocket, we don't take that capability, so we need fins to stabilize the rocket so information technology flies safely. Dr. Zooch models effort to hide these fins by making them look similar role of the rocket exhaust - or the flame coming out the dorsum.
This rocket uses standard 18mm size model rocket motors and tin can exist launched from a small launch pad; making information technology economical to fly.

We rank this model every bit a Skill Level 4 kit using our classification organization of kit complexity.
If y'all've congenital rockets earlier, this one won't seem much different than what yous've assembled earlier. For the most part, the kit doesn't have any parts that are out of the ordinary. The main reason this is not a lower level is that the instructions are a piddling confusing in a few places. It didn't assistance that Semroc (the manufacturer of the kit) chose to reduce the size of the instructions so they would fit onto standard 8-1/two X eleven sheets of paper. The text is actually tiny and hard to read if you have any type of vision problem.
The associates of the transition is probably 1 of the more challenging steps if you've never assembled a newspaper transition before. You also have to cutting a torso tube to length. The instructions recommend using the supplied centering rings to guide the blade. I prefer to use the Estes Tube Cutting Guides considering they lock downwardly tighter on the tube, and then you lot get a straighter cut.
The Landing Leg Spoofs (LLS) are fabricated from heavy cardstock paper. We were confused a little bit near where they were located on the rocket, because they accept different shapes. And they have to be curved to conform to the body tubes. This means y'all end up with iii unlike versions, fifty-fifty though they come every bit 2 shapes. The direction of curvature makes a difference on the inner LLS parts. To create the curvature, we dipped ours in h2o to moisture the paper so it would be plyable without creasing as it was wrapped around a tube. Simply this meant nosotros had to let this dry overnight before continuing. Check the positioning of all the parts by laying them on the rocket simply to be sure you take the curvature correctly oriented. You can re-dip them in h2o and re-curve them if you have 1 or more of them curved wrong. Once dry, we coated the paper with water-thin CyA glue (super glue) so that they could be sanded smooth. This worked surprisingly well. We painted them black earlier applying them to the rocket, because it would have been extremely difficult to mask them off subsequently. Blackness was the color that SpaceX showed on their website. But in hindsight, nosotros didn't look at the true colors of the landing leg covers on the bodily mission, and we should have painted them white. Doh!!
The instructions on the attachment of the flame fins is confusing. The illustrations show curt tubes for the where the flame fins are attached. In actuality, the kit comes with longer tubes. Since moving the fins back increases stability, we chose to have the tubes extend out the rear further than what the instructions show.
The one thing that we didn't like most the textile option was that the daze cord ballast is made from tyvek instead of paper. While it is very strong and won't tear, it doesn't glue very easily using wood glue or white mucilage because tyvek is a plastic material. Glue doesn't penetrate into it, and will skin off. You lot have to use super glue for this, which is tricky because it is and so easy to gum your fingers together when folding up the shock cord anchor and gluing it into the body tube. If you don't want to use the tyvek shock string anchor, you can hands cut one from some regular copy-paper.
The kit also comes with a big "U-cutting" parachute. It has cut lines on the surface and so you tin choose to utilise either 24", 18", 15" or 12" parachute. The instructions don't tell you which dimension to cutting, then you accept to make your own choice. We did the 15-inch because it would fit easily into the 24mm diameter body tube.
Here are some tutorial videos nosotros made that we think will help make the assembly of this rocket easier:
- Assembling a paper transition
- Motor Mount Associates
- Using the Estes Tube Cutting Guide
- Using the Estes Ultimate Tube Marking Guide
- Positioning Water-Slide Decals
- Attaching Strings to Parachutes
- Olfactory organ Cone Fit
- Basics of Motor Selection
Even though adding all the scale detail to the rocket is challenging, nosotros think that when you are done with this kit, you will find information technology is a very nice looking rocket and will bring you a lot of pride and a sense of accomplishment.
Q. Could you make information technology a cluster of iii motors?
A. Trying this would definately brand this an infinately circuitous rocket, and most likely an unstable ane. Yous oasis't seen the kit yet, and so we'll tell you ahead of fourth dimension that the rocket needs a lot of olfactory organ weight as it is to brand it stable. Putting more heavy motors in the back would arrive even more unstable. Our recommendation is that you lot don't try. Information technology would be a dangerous undertaking if you didn't know what you're doing. And if you have to ask this question, our guess is you lot don't know what you lot're doing - specially in regards to having a skilful understanding of rocket stability. Please note that we're non trying to embarrass you. We just want you to be safe, and to keep spectators around you safe besides. We'll assistance you larn about rocketry, and so yous can brand decisions like this yourself. Start with the volume Model Rocket Blueprint and Structure to start your journey and learn more about rocket stability. If you want to try a rocket with strap-on boosters and that has a three-motor cluster, check out the Flying Machine kit.
Q. Practice the booster pods separate and land upright?
A. Of form non... Don't be silly. This is a unguided model rocket.
Q. Tin information technology be flown without the flame fins?
A. No. It is unstable without fins. Don't launch without them.
Q. Where can I become a Tesla to fly in the payload bay?
A. Don't know... Peradventure you can sculpt one out of FixIt epoxy clay. A improve payload is an altimeter, like the Jolly Logic AltimeterThree.
The Falcon Heavy kit features modern edifice techniques and materials similar laser-cutting fins and Kevlar daze cord. The instructions are excellent, and the parts are all carefully crafted from the highest quality materials.
Paper tubes: These are prissy quality tubes. They are easy to mark and piece of cake to paint. In edifice this kit, you are required to cut 1 tube to make the base of the payload bay.
Precision Turned Balsa Nose Cone- Balsa has been used from the very start in rocketry to make olfactory organ cones. You tin easily insert and glue screw eyes in the base of operations, and it is easy to finish and accepts pigment well. The lightness of balsa ways yous'll accept a lightweight rocket too.
While we plant the nose cones had a flattened tip from the milling process, it doesn't accept much work to round them off with sandpaper and to also get the rocket to a smooth surface appearance.
Basswood Fins - The tight wood grain of basswood means at that place is less filling and sanding needed to get a shine surface compared to using balsa wood. They likewise take the little swirls cut into them to make them look like rocket exhaust flames. And these fins have perfectly foursquare edges and so it's easier to get them aligned. They tin can hands be airfoiled for a significant improvement in altitude.
Pre-Printed Plastic Parachute: The colorful parachute is easy to see against the heaven. It will instantly take hold of your centre during descent, helping y'all recover your precious model. You'll love the way it looks as it descends to the footing because it is so easy to see in the sky.
The kit also has metal screw eyes equally anchors for the traditional rubberband daze cord that comes with this rocket kit.
Shock Cord:The shock string is safe and stretches to allow the nose cone to deadening downward and minimize impairment to the rocket.
The Falcon Heavy is sized for 18mm bore motors. The parts are nice and things fit together almost perfectly.
Engine Block:The paper-thin engine cake securely prevents your motor from flying upwardly through the rocket.
Newspaper Centering rings are used to make a very sturdy engine mount.
Spring steel engine retainer clipallows you to bandy out engines between flights in simply milliseconds. It is really that fast! This engine hook is for E-size (3.75 inches long) rocket engines. The kit likewise includes an orangish spacer tube you tin can utilise in front of shorter D-size rocket motors.
This kit besides includes other components to complete the model. Yous'll see:
Balsa coupler that is used on the base of the payload fairing. It is balsa so that it blocks the tube and so a screw eye can exist inserted to attach the parachute.
The hollow coupler is used to bring together the ii pieces of the cadre tube together.
Landing Leg covers are laser-cut from heavy cardstock paper. They are all the same size, then you don't have any work to practise to make them fit around the rocket. You do have to scroll them, which can exist done by moistening them with water and wrapping them around a tube.
The lightweight cardstock transition blueprint is laser cut and is sized perfectly. That also makes assembly easier and quicker.
1/8" Launch Lug:These are standard size launch lugs, and so you tin can fly this rocket on uncomplicated low power pads like the Sky Launch pad. Launch lug standoffs from basswood are included because this rocket has a nose that is bigger than the core where the lugs are fastened.
The Wood Dowels are the struts that secure the strap-on boosters to the core vehicle.
Metal Washers for adding olfactory organ weight to the rocket to brand sure it flies straight and true.
Metal Screw Eye that goes in the base of the nose cone so the shock cord can go along everything attached. Some other screw heart is used to adhere the washers to the base of the nose cone.
The Falcon Heavy rocket too comes with a parachutesnap swivel. This minimizes the chances of the shroud lines on the parachute tangling every bit it descends. And it makes it easy to adhere to the rocket prior to flight.
Waterslide Decals - The rocket comes with decals you tin add to brand the rocket look more realistic.
The instructions are so entertaining, that they are a definite kit characteristic. No boring "cut this tube, draw this line" steps here. The drawing Dr. Zooch will walk you through each step with such bully humour and sarcasm that you will want to read this over and over! Dr. Zooch is known for helpful comments like "the better the job on cutting out, the less the rocket will suck."

Nice kit, non sure if I am going to install those bottom "flames"
Looks more like a level three to me, merely take non yet started information technology.
Overall it'south a overnice rocket :)
