Default Mystery rocket

Hi all,

I picked this rocket up from a hobby shop which is closing its doors. It was already assembled as seen in the attached picture. It is BT-60 construction, 32" long with a 24mm mount. I have no clue if this is a kit or someone's own design. Whomever put this together paid a lot of attention to detail. The fins are airfoiled, well filleted (not overly done but very crisp), no body tube spirals in sight. Lugs are 1/4". Motor mount is epoxied in with a length of kevlar incorporated to the mount. They also took the time to loop top end of the kevlar and seized the end (presumably to allow replacing the shock cord). Nose cone appears to be a PNC-60AO.

I've been searching high and low to see if this is a kit or not. But considering what what into this I just had to give this a home. Has anyone see a kit like this before?

I don't recall Estes making a PNC-60AO. They make a PNC-55AO (Goblin, Bandit, etc). It's probably a PNC-60AH (Red Max, Omega, etc.). Semroc makes/made an upscale BNC-60AO.

I also don't recall seeing an Estes kit that looks quite like that and the internals are not what's included in their kits. If the body tube is 18", it could be bashed from an old Screamin' Mimi kit, but it's likely just a scratch build...a well executed one at that.

PNC-60AH does seem more accurate. I was on e.rockets eyeballing the nearest size and shape. If the body tube is a single piece, then it is 26" long.

Thanks for taking the time to reply. I appreciate it. I have to draw this one up in Open Rocket to see how it sims.

Use a flashlight to look inside for a coupler - unless it was scratch built from a tube from Totally Tubular or other tube vendor. If it is two tubes, and is definitely made from Estes parts, it could have been built from the Designer's Special.

Hint #1: Do not use magician's flash paper for recovery wadding!

Hint #2: Clean your shoes after flyin' in that cow pasture - that ain't no dirt clod on the sole!

Scratch built. You can tell by the rear fin space from the tube and the fin shape. It was built to reduce common flight damage so it could be flown repeatedly. Also look for interior scorching of the tube.

I never thought about the fin spacing in that way. Thanks for the insight, Jerry. This bird has never flown either. All I have to do is finish it an come up with a name for it. I put the dimensions into Open Rocket and it shows to be more than stable. Greg, I did do as you suggested already and found no coupler inside.

That is the way all bulk pack rockets for students, scouts, etc. should be designed. No swept fins, no heavy plastic fin cans. Let the motor take the landing hit, not the rocket. That way, a streamer can be used instead of a chute for schools that have limited recovery space.

Um, Estes likes selling (replacement) product.

U.S. Rockets has a philosophy of accepting all lengths of motors, motor hits first when possible, and more the merrier.
