Board Thread:General Nerf discussion/@comment-27306930-20160925014800

Hey, good news. I figured out how to make the Extreme Blastzooka fire Nerf missiles really well. For those of you who've tried it, the accuracy is, well, um, random on the stock XBZ. However, it fires Buzz Bee missiles beautifully.

I discovered that there is a design difference between the two missiles. The BB missiles have a bulbous hollow section in the head of the projectile, while the Nerf missiles have a tubular hollow space running up to the head.

Problem is, the XBZ releases the air through two small holes in the right & left side of the dart post. The end is actually capped. In the BB missile the bulbous chamber acts like a little air tank, causing the pressure to build  up and eject it from the dart post. The Neft missile has no such chamber. The air has to flow between the dart post and the inside edge of the missile, some moves toward the head, and some escapes out the back. Only the air captued in the small void at the head of the dart serves to eject it. Plus I'm pretty sure the high pressure blast temporarily deforms the missile causing additional instability.

The solution is removing the end cap on the dart post. I used a simple utility knife to loosen the thermobond between the cap and the tube and voilà, it slid right out. Nerfs and Buzz Bees perform equally well now.
