Brief:
The main stay of the Corn on the cob shaped oddroc collections by First Flight Hobby. This 18mm rocket once complete is interesting and fun. It promises to be a head turner and also a great flier.

Construction:
The parts include:

• One styrene foam corncob
• One body tube
• MMT 18mm tube
• One engine block
• 2 centering rings
• Small bag of bb's
• 12" parachute
• 2 sheets balsa fin stock
• Kevlar® shock cord mount
• Elastic shock cord
• Motor hook
• Instructions
• Snap swivel
• Small screw eye
• Nose block
• Chute reinforcing tapes
• Launch lug
• Bag of bb's with corn husk scraps
• Shroud line

One of the things that really showed me that this company cares about its customers is that each small bag of parts was signed after the parts where placed inside. Also the fact that they hand drew the corn in the instructions when explaining the insertion of the stuffer tube into the corn body.

Reading the instructions you almost laugh at the thought and humor put into them at a few points. Well worded and thought out, easy to follow. Though I suggest the fin pattern being on its own sheet.

To build this oddroc you first need to assemble the engine mount and stuffer tube assembly. After building the engine mount, the instructions say after gluing the cord to the engine mount to feed the Kevlar® cord through the stuffer tube. A better means is to feed the free end into the MMT so that it is hanging out the back then gluing the mount in place. This allows you more control when the times comes to tie the shock cord to the Kevlar®.

Next part is to carefully cut the four channels into the foam corn for the fins. I used and would suggest a Dremel with a 1/8" cutting wheel attachment on its second to lowest setting while using a piece of angle iron for a guide. This to give you a good clean cut.

Once that is done, you want to mount the stuffer tube. Test fit first! I found I needed to wrap 5 turns of masking tape aroung the middle to get a snug fit before gluing. The next thing you do is sand and fit the nose block. Making sure it fits well enough so that when you put the cap on it matches with the orientation of the corn.

Using foam safe 5 or 15 minute epoxy, glue the block in place while the block is in the tube to aide in the alignment.

Let the rocket dry nose down for a least an hour before going on.

While the nose and body are drying, cut out the fins sealing and sanding until you are happy. Leave them natural to match the husk on the corn. Once complete, I used Great Stuff foam to fill the body gaps around the stuffer tube.

All in all this rocket was one of the most enjoyable build I have done in a while.

Finishing:
The only finishing needed is a touch of flat or matte non-corrosive paint to protect the rocket and maybe using some epoxy paint on the inner exposed foam to protect it from damage.

Construction Rating: 4 out of 5

Flight:
I flew this oddroc twice on C6-3 engines. The first flight was great and cleared the pad with no issues. It screamed into the sky and landed 120 feet from the pad. I lost sight of her during the coast phase due to over cast so she got some good height.

The second flight was a mirror of the first.

Recovery:
It came down slightly faster then I liked so I will be increasing the chute to a 16" with a controllable spill hole.

Flight Rating: 4 out of 5

Summary:
This rocket is a head turner, and I feel that it is a must have for anyone who like oddrocs or, like me, just likes to take strange things to the range and fly them while others look at you like you are crazy.
