RP has a news release of USR Sonic 3100 where Chris Pearson felt it is duty to go there and make incorrect and unjustified comments because he has been stalking and harassing me since the 70's.

The truth may be out there but it is not in Chris Pearson's head.

There are not and never have been dumpster tubes. There was only a brief time any CD parts were used and when CD was sold off it was Stargate not USR that purchased the airframe parts. So Chris Pearson is in error and engaging in trade libel, as usual.

There are a few other interesting errors and intentional attacks.

Chris was not a dealer per se. I went to LDRS and he promised to return the kits I didn't sell by UPS so I could catch my plane. 4 MONTHS later he had still not returned them and when he finally did, they had each been opened, I presume photographed and catalogued, and put back in incorrect order with many missing parts, presumably for industrial espionage. The man is a thief in my own experience.

Shortly therefater his Ace license expired and he was making bad and unpermitted copies of Ace and USR kits. That was North Coast Rocketry. He was the subject of the "GORC" parody catalog distributed at LDRS in Medina, I believe 3 or 4.

As for Hi-Test 2650 fiberglass tubes they were not from a dumpster. NVF had a west coast location at that time and was supplying ejection seat motor casings for the precursor to Universal Propulsion. My current supplier still makes those cases and still inspects each one and still offers me the "rejects" as well suitable for "structural applications", ie. airframes. No current kit uses them because my commercial users soak them all up and more. The markings he refers to are inspection marks where small voids were in one or more layers of the THIN fiberglass tubes. I purchased them at half price, and all consumer feedback was sensational.

It's true the CD nose cones needed to have the silicon mold release cleaned off before painting, but USR used balsa nose cones from the day CD went out of business IIRC 1982 or so.

The Sonic 3100 tubes were made about 1995-6 from a west coast vendor and are MUCH stronger than the Ohio supplier. None have EVER been reported as shredding and we certainly tried with HPR motor testing up to 75mm. Just this month my son was walking over an entire "floor of boxes" of BT-30-24 on top of which we have stacked some other tube sizes like 98mm motor liners and such and asked why we had so many of them. We do have plenty. They were the tubes showcased on rocketmaterials.org as the strongest conventional paper tubes in the world.





While it is true that I purchased over a dozen companies when they failed in the marketplace, it is not true that those parts were ever used. Some techniques were, but for the most part all USR designs and methods were developed by me and are still in use.

In short Chris has a stick up his a** over me, always has, always will, and in no way needs facts to feed his predeliction to do so. His internal fictions and fears are plenty sufficient.

Korey made Ace kit parts and I made USR kit parts. Another Pearson-ism debunked.

I personally wrote and published all the AIR reports, all the USR instructions, all the Ace Rockets instructions and even some stuff for Aerotech. The AIR-3 and 4 techniques were developed by Korey and myself by FLYING ROCKETS, particularly what we now call HPR long before Chris ever heard of it or tried it.

Chris Perarson is an outright liar.

Hey Chris, when Matt needed tubes for a Minotaur scale model, guess who he contacted. Ask him the quality of tubes he received.

Just unilaterally attacked Jerry
