Showcase your rocket here. Kit or scratch-built. The only requirements are 1. minimum diameter 2. 54mm airframe.

Post your best altitude to date or estimated altitude if unflown.

I'll kick things off with mine. Presenting...HammerSpace.

Filament-wound fiberglass airframe, G10 fins by Public Missiles, altimeter sleds by Additive Aerospace. Featherweight Raven3, Communication Specialists AT-2B tracking transmitter, Cobra CDR 820 high-definition video camera. The only flight to date was at BALLS 24 on a CTI L265 to 21,950 feet above ground level.

Superb.
 
Can I ask you about the static sampling ports / access for the screw switches - i.e. how many and where did you situate them, please?

There was a hole over each screw switch (two total) and one for the camera lens; all doubled as sampling ports.
 
Here is my Madcow Tomach:

The build thread is in my sig with more photos. So far the only flight has been an I600, which only got 4743' due to weather cocking. In eleven days, on June 18th, I am going to be launching it on an L935 for my L2 attempt. I am hoping to break 20k with that flight.

Good luck, please let us know how it goes.
 
Here's mine. It flew at Aeronaut 2015 on a CTI L265. It weathercocked pretty bad off the pad but still reached 24,626'. The parachute deployed at ~350 mph because the trajectory was so flat. I wish I could have gotten the onboard video.

My 54mm Tomach with a 54/2550 in the tailpipe. Yet to fly. I am really really excited to try this thing out.

Pretty cool. Does the antenna for the track has any risk of damage from the ejection charge? I just have never seen it come though an AV bulkhead like that. I usually tape them to the shock cord with a kevlar blanket around it.

I hotdog-bunned some masking tape over the antenna to protect it, and the drogue charge is small anyhow.

I have always wondered that too. On my next, I plan to use a short section of RC car antenna tube glued through the bulkhead that will protect the antenna. My Marshall TX has a replaceable antenna that unscrews but I want to protect it as much it as possible.

Seriously cool builds guys!
 
That is some seriously impressive altitude.

Very impressive for a single stage and not many people can claim that alt on 54mm single stage stage.

Unfortunately for most of the sites I know of on the East coast, the highest waiver is currently 18K. I am hoping to attend Airfest in 2017-18 to push this rocket to it's max potential and hopefully hit 25K, which is likely a stretch for the design, but a personal goal none the less. I did just got my hands on a nice 60" CF tube and I am planning on building a scratch 54mm, inspired by Jim, to hopefully touch the 32K line using a new motor Loki is working on for his 54/4000 case (43.85" of hardware), which I just picked up, but we will see.

That would be quite a motor for 54mm. L record would be quickly toast I think.

Hoping not to hijack here, why are these MD bird's fins not mounted against the aft end of the rocket, but 2-3 inches up?
