Well, I received my Hijacker kit from Mercury Engineering last Friday. My initial impression is that it's a good quality kit. I was a little surprised at how thin the body tubes are, but I suppose if they were thicker it would make the rocket that much heavier. The instructions are very clear and concise, and easy to follow. Lots of good drawings make the steps very clear.
I was originally going to build it with a 2x24mm cluster motor mount, and even ordered the cluster mount with the kit. But I decided to build it with the single 29mm mount, so I can use F and G motors in it. I'll save the cluster mount for another rocket. I also ordered the 24mm to 29mm adapter, but I don't think I can use E9's with this rocket. The advertised weight on the Hijacker is 16oz, and the E9's maximum liftoff weight is 15oz.
I'm excited about the rocket, so I dug right in. I put the motor mount together per the instructions, and used carpenter's glue. I've been around woodworking all my life, and am very confident in the carpenter's glue's strength. The motor mount didn't come with a thrust ring or motor hook, of course, but did come with a length of foil tape to wrap around the end of the motor tube. This is to prevent damage to the tube from the masking tape used to hold the motor in. The centering rings are laser cut fiber, and seem plenty strong enough.
