Default Old Motors' Photos

I am going to post pictures of some of the older motors in my collection. I started in 1967 and have been a NAR member from 1968. Served on S&T and other NAR committees, but my military moves meant that I usually could not chair a committee long. Was on the Board of Trustees for nine years.
My motors are stored in a way that only the ones used for flying are readily accessible. When pulled out they all looked like this. The red ammo can was the first.

I do not claim that I have all of the motor histories or are totally accurate in my recollection. I welcome any clarifications or additional information.

Model Missiles Inc was set up by G Harry Stine. Brown Fireworks made there first motors based on Orville Carlilse's half-inch motors, but in the now standard 0690 x 2.75 inch size. One live motor and one flown in a Camroc at NARAM 15.

Exclamation

Estes B.8-6 from '68, B .8-5 from'67, and a C.8-0 booster from '67. NAR newsletter said that the C was certified in 1963. Old pound- second designation.

Second photo is two Estes B16 motors at the bottom - the nozzle is on a B16-5. No date codes. Designation was based on an incorrect reading of the test equipment they had at the time. Above them are a Centuri B3-5 and the nozzle of an Estes B3-5 from 1967.

According to Stine the Uni-Jet motors were produced in 1964-65. They were 0.5 x 2.25 inches. They had a propellant that did not age well and they became unreliable. They were equivalent of 1/2A motors. The ones I have are a D2, D3, and D4. I believe the number is the delay. The nozzle is one the D4.

The pride of my collection is a Prodyne. NAR newsletter said that they were certified in 1963. This is a Prodye Hurricane BE-3.5-2-8. NAR equivalent D2-8. Their larger motors were Cyclones in E and F impulses. Again, the old pound-second designations
Second photo is the nozzle.

Final for tonight is for flying your Estes Omega with Cineroc. D12-0/D12-7. Date peeled off of booster and the dash 7 was made in 1971. More later

I will Steve. Not sure how these photos show up on a good computer.

Obviously the two stage combo is a D13-0/D13-7. D13's always worked for me, but I did see several that did not.

Over on TRF is a thread on old motors that deals more with F and up. I do not have any of the motors like the Syner-Jets or Plasma Jets or Ravanna. I did provide a couple of catalogs to www.ninfinger.org that were from a couple of manufacturers.

Will post more pics tomorrow. I apologize if the quality or orientation of some of them are not real great. Photos taken in my small work area. Ammo cans now stored again.

Chas

Very Nice Pics.
Especially the B16-5/B3-0
I know at one point Carl at Semroc was going to re-create many of the old core burners, but he never was able to get back into producing motors before he unfortunately passed.
He truly was a one-of-a-kind gem to our hobby we likely will never see again.
