To make ONE Grot Rokkit, you are going to need the following parts:
 
•     One "Missile Shaped" plastic tube (cap from a pen, plastic bullet, etc.)
 
•     One Grot Head (you know you've got a spare grot or two somewhere)
 
•     Plasticard of varying thicknesses (0.5mm and 1.5mm or thereabouts)
 
•     One Small Wire Nut (the kind electricians use to splice wires together)
 
•     Some 'Green Stuff' (or any other modelling putty)
 

STEP 1: Basic Shape

The first step is to get the basic rokkit shape down. The basic "missile shaped" tube is something you'll have to look out for. I used the shell from a 1:35 scale Sturmtiger model kit, but any cone-shaped hunk of plastic will work.

The cap from a Sharpie, a toy bullet, I've even seen the little widget inside a bottle of Guinness used as the base for a grot rokkit. Keep an eye out, you'd be amazed at the kind of junk that can be used as the basis for a modelling project.

The shell from the Sturmtiger kit is a bit long so I cut it down to size using a modelling saw. I wanted the fuselage of the rokkit to be sort of 'stumpy' looking, as opposed to a long, sleek 'cruise missile' shape.

After cutting the shell to the length I wanted, I glued the wire nut in place as the thruster. You want to make sure the size of the wire nut roughly matches the diameter of the hunk of plastic you've chosen as your rokkit. Too small and the wire nut will slide all the way inside, too big and it won't fit.

Once you've got the right size wire nut, make sure you glue it in straight. The easiest way to accomplish this is to stand the whole thing on it's end (see the picture on the left). Make sure the 'rokkit' is sitting straight up on the wire nut 'thruster', without leaning in any direction.

STEP 2: Cockpit and Wings

Now that you've got the basic fuselage put together, it's time think about how to make it look like it'll fly. We're talking about a grot rokkit here, so we need someplace for the little guy to sit.

Using a pin vise and a hobby knife, I cut a hole in the fuselage to act as the cockpit. I placed it about halfway between the nose and the thruster. I also made sure to make it just big enough so that the head will sit in it without dropping inside. The fact that grots have big floppy ears makes this pretty easy. Keep your grot head handy when cutting the hole for the cockpit, so you can check the size while you're cutting.

After you're happy with cockpit, it's time to put some wings on this little beastie. Using some thick plasticard (1.5mm or 2mm work well), cut some basic triangular shapes for the wings and tail. I made the wings on my rokkit about the same length as the diameter of the fuselage, roughly 1/2 inch. I made the tail slightly shorter than the wings, because the tail on most aircraft are shorter than the wings.

Once you have the wings and tail ready to go, it's time to glue them in place. I glued the tail on first, directly behind the cockpit. After that I glued the wings on either side in an angled-down position.

I've had a couple of people tell me that the wing configuration makes it look like a Colonial Viper. What can I say? I've been a Battlestar Galactica junkie since I was a kid.

STEP 3: Detailing

Up until this point, the grot rokkit is looking pretty sleek, like it could almost fly. While aerodynamics are important if you're an aircraft designer, it's not exactly the 'Orky' way of doing things.

I wanted the wings to look like they were an afterthought. Something that just got bolted on to try and improve performance after a failed test flight. Isn't that just like an Ork, build something that flies... but forget to build in a way to steer it.

I cut a few small pieces of thin plasticard (0.5mm) and made some 'rivetted' strips to hold the wings in place.

Making the strips is easy. Using a ballpoint pen and a semi soft surface (the rubber cutting mat), push down on the plasticard until it leaves an indentation. When you turn the plasticard over, the bump on the reverse side looks a lot like a rivet.

Once I had several small strips with rivets on either end, I bent them in half so they would fit the angle between the wings and the fuselage.

Once glued in place, the strips gave a much 'orkier' look to the rokkit.

STEP 6: Pilot

Once you're happy with how the rokkit looks, it's time to put the pilot in. I stuffed a wad of modelling putty into the cockpit to give me a surface to glue the head onto. While the putty is still somewhat pliable, add a drop of super glue to the bottom the grot head and push it into the modelling putty.

There you have it! One Grot Rokkit, ready to go. Now you can glue it onto whatever Orky vehicle you like to give it that little extra punch.

My version is a bit smaller and less detailed than the Forgeworld Grot Bomb. But hey... they don't cost you sixteen bucks a pop either!

Group Shot!

A whole skwadron of grot rokkits, ready to rain high explosive death on anything in their way! I built these three to go on the Tater Titan.
