Hard to say who did them. I agree, the one is an Enerjet. Not sure who the other one is - looks like an NCR Impulse, but it isn't one of them.

Rich, "you ignorant slut!" (SNL reference)

Irv Wait invented Enerjet and sold it to Centuri. He interestingly made motors for a movie I worked on and also made motors for called Mosquito Coast (Harrison Ford).

Irv reminds me of a 20 year older Scott Dixon. Scott is a polyall god, and incidentally makes propellants and rocket motors. Irv is a rocket god that had to learn about polyalls and epoxies to make his art work.

Irv was an old school case bonded coreburner, pulled mandrel guy.

By comparison I am a cast to liner, cut, drill, plop and chop guy. I have access to better polyalls.

Irv ran Rocket Development Corp. out of Seymour Indiana in the '60s. He developed the first commercial composite motor, the Enerjet 8, and the "Ignitrite" cluster igniter. He worked with Centuri and the Enerjet line was developed with motors and kits and the Igniterite became the Centuri Sure-Shot.

There are two other RDC catalogs on the ninfinger site.

So if the motor on the right is indeed an unlabled Enerjet, prototype or F67, its heritage goes back to the Enerjet 8. Didn't want to get too far off topic...

The Centuri Sure-Shot (R) was Thermalite (R) without the external wires FSI (R) had.

This is a good thing (TM).

Just Jerry

As others have stated, the one on the right most certainly appears (is) an unlabled Enerjet.

I have an unlabeled Enerjet F67-5 given to me by a former Centuri engine plant manager several years back and it looks just like this one.

Are there any markings, like in black marker, written on the outside of that case? Mine as F67-5 written on it in black magic marker, with another number like 389 or such, which I will assume is probably a 'batch' number or such.

I have to agree the one on the right is an Enerjet. Could the one on the left be an FSI Thunderbolt? I believe these were 1" in diameter and about 6" long.

They weren't in production for long. I believe an accident with a younger user led to their demise.

FSI Thunderbolts had brown phenolic cases.

I watched AT deliver a batch of "similar performance" motors to Lonnie for some movie deal.

I WAS IN THE ROOM.

Not an FSI Thunderbolt. I go with an Enerjet and something made by Aerotech. Both early models

That one is not Enerjet or Aerotech for sure.

It says Flight Systems Thunderbolt on the side.

It resembles Ravenna Rocket Research motors.

The black one does not resemble anything I have seen as a commercial product.

The ones in my above post are FSI thunderbolts F-32
