X-Calibur Updates

My Public Missiles (PML) X-Calibur. This is its 3rd paint job. It started out metallic green and purple, then it
was red and yellow, and now finally the gray and black. None of the color schemes I've done on this rocket
have looked very good to me. For reference, the rocket is 4 feet long and weighs about 2 pounds.

My Public Missiles X-Calibur was one of my first high power rockets. I built it in late middle school or early high school so it's something like 16 years old. It has many flights on it and has always been a decent flier. I intend on continuing to fly it as a "cheap" and simple way to fly G, H, and I motors. I decided to make provisions for it to use an altimeter for ejection. It will remain an apogee event only rocket, since there just isn't space in it for dual deployment.

This will be an improvement over motor ejection because there will be no calculating/ guessing delay times, and having to drill them to the correct duration. Instead, the altimeter will sense apogee and fire the ejection charge at the right time, every time.

The pictures summarize what I did to install the altimeter mount, and keep enough space to also fit a tracking transmitter (I consider the tracker an absolute must on high power rockets, so I didn't even consider leaving it out.)

Payload Bay

Payload Bay Components, Spread Out

The antenna of the tracker must go inside the nose cone in order to fit.
This is a good thing as it will keep the antenna straight and give it some protection.

This is actually the electronics sled out of the Super Weasel (R.I.P.)

Backside of the Electronics Sled

I used a Velcro strap through slots in the tube to keep the
electronics sled "clocked" properly.

This is the access to install the wire that will connect to the
 e-match and ejection charge.

This picture shows the alignment of the air sampling hole in the
payload bay with the rotary switch on the electronics sled.
On the pad I'll stick a small flat head screwdriver in the hole to
turn the switch and arm the altimeter.

This is the bulkhead of the payload bay. The drilled hole is where
 the wire will exit to connect to the ejection charge in the
lower portion of the rocket.
