I've flown a 4" Blue Tube airframe with G10 fins to Mach 1.5 on a punchy 75mm EX motor. No problems.

As Rocketjunkie mentioned, LOC once manufactured a kit called the Laser Loc. It came in two...

Thanks Coop, Bryce, and Gerald for the pics. Feels good to be "legit" finally. :)

Now to fly that O motor at XPRS...

Thanks, Mason and Dixon! If I had used PML phenolic, I would've laminated the tubing. But that would've added extra weight.:no: Flexible phenolic does the job just fine.

The rocket has flown four...

So this is the year I finally decided to go for level 3. I've been flying with Tripoli since 1994. This is not a build thread, just a bit of posterity.

I decided on a 1/3 scale patriot with a...

jus, your mailbox is full.

Not sure, but why would you want to?

Ky Michaelson's rocket was an S.

Not all solid motors produce obvious flames. Kn03/sugar motors are all smoke. Adding metal to sugar propellant can produce a visible flame, but nothing like AP with metal. I'm sure somebody here can...

Short answer, because of the AP.

Not all propellants contain aluminum, either. Some have no metals at all. But, different metals and different amounts of those metals can change the...

Might be hard to find, but the US Rockets H90 Firestarter would be my motor of choice for L1.

Very nice, Tom. That's one hell of a rocket!

Exactly!

You mean the Kitchenaid mixer that my wife already had? Zero. Though I did buy a second bowl and paddle just for propellant. Anyway, you don't need a mixer.

Since January 2013 I've burned 23,000 N-s in research motors. That's three big 75 L's, one 54 small L, five 54 K's, and several 38 and 28 H and I motors. Never really done the math, but I would guess...

Fill the delay well full with lithium grease. Just be sure not to stick the igniter head into the grease when you insert it.

BTW, for those that don't get sarcasm, I'm not implying that CTI did anything wrong, 'cause they didn't. But neither did AT.

What do I care, anyway. I fly only research. That and Jerry Irvine...

My remark wasn't aimed specifically at your comments, Fred. The 'hobby shop won't check for certification" comment and earlier posts in this thread about AT being irresponsible for one thing or...

Agree with you, Peter.

The "concerns" raised in this thread about Aerotech being in some way irresponsible are totally bizarre to me. Some folks on this forum need to GAFL.

Which hobby shop carries H motors?

Anybody out there now? How's the weather?

You don't have to glue on the thrust ring. Just use masking tape. That's ALL there was for years and it worked just fine.

Carvac, that wasn't my point. It was the "Aerotech promoting that kind of behavior" that made me chuckle.

Why would CTI make a motor that shreds almost any rocket?? What are they thinking!!?

...seriously?

I flew a ton of these motors in the early 90's and loved 'em! The trick is, as Jeroen mentioned, to not insert the ignitor all the way up the core. Halfway is where you want it.

I miss big black...

It can be done and has been done by the "research" crowd.

Hoping to make it out on Friday.

Single use motors, although after each firing I've been able to cut off the ends and use the shorter case again. I'm using "recycled" CTI nozzles and bulkheads secured with JB Weld.

...composite motor cases. Anybody here done this? For 54mm, I've experimented with several layers of carbon fiber and Aeropoxy over an aluminum mandrel and had success. These motors have not exceeded...
