GORMLEY, Ontario CAN — A motor testing session was held at the Cesaroni Technology Incorporated facility in Gormley, Ontario on October 24th and 25th, 2009.

A total of thirty-one (31) motors were fired to certify eleven (11) new reloads. The certified list includes a G, an I, an L, six M's and two N motors. The propellants included Blue Streak, Classic, Imax, White Thunder, and Skidmark. Two new propellants, "Pink" and "C-Star" were introduced. The total fired impulse fired this session was 190,005.8 N-sec (16.0% R).

At the top, the certification burn of the new Pro98-6XL N5800 which uses CTI's new C-Star propellant. The second photo shows CTI's new Pink propellant, an M1675. Below that, on the right, the new Pro54 motor spacers and on the left, the Pro38 models showing the regular spacer (in blue) and the XL spacer plus a suggested recovery attachment method using a modifed Giant Leap Hard Point recovery anchor.

Two of these new motors are in the top of their impulse range:

• 9994-M3400 White Thunder (95.2% M)
• 20146-N5800 C-Star (96.7% N)

The ABC 4701-L1290-SK reload, designed for the AMW 76-6000 case, ships with a single-use nozzle and requires the standard Pro75 CTI nozzle carrier to complete the assembly.

Testing of spacers continued this session, including spacers to accommodate Pro38-6GXL cases, the Pro54 family (including the 6GXL case). So there are now two spacers for each of the Pro38 and Pro54 lineups. The products will ship with instructions on proper use. The XL spacers are for use in XL cases only.

As a result of this and previous testing, 38mm, 54mm, 75mm and 98mm spacers (alone or stacked) and the Pro29 tapered closure form part of the certified motor systems from CTI. These spacers (38mm, 54mm, 75mm and 98mm) and optional closures (29mm) will continue to be included in upcoming tests to observe the effect of 'accelerated' usage.

While these motors were certified in Canada, a reciprocal agreement between the Canadian Association of Rocketry, the Tripoli Rocketry Association and the National Association of Rocketry means they may be flown in many jurisdictions.

I am very pleased to announce the certification of these eleven (11) new reloads from Cesaroni Technology, Inc. Individual certification letters follow for each motor. These letters and the accompanying thrust curves will be available on the official CAR website soon. As time permits, photos from some of the firings will be posted as well.

Respectfully submitted,

Thomas Raithby
Chair of CAR Motor Certification

Any details on what the characteristics of PINK and C-STAR are?

C-* (pronounced 'see-star', hence C-STAR) is the characteristic velocity, a measure of the combustion performance of a rocket motor/nozzle: http://en.wikipedia.org/wiki/Characteristic_velocity. This propellant is a high performance 'real propellant' with high metal content.

Pink is just pink. Some may call it violet. A little story behind it: a year ago Paul Robinson (AMW) called me, and suggested a new approach to make a purple flame. We tried it, and it came out Pink! Paul was very disappointed when I called him with the results of the firings. But, the girls at our office really liked it. Recently Haley's pink L3 rocket was posted here: http://www.rocketryplanet....hp?t=5020&highlight=pink. I suggested to use a pink matching motor. Since this was only days before the certification session we added it 'last-minute'. If there is a demand, we may certify other motors. All credit goes to Paul.

High performance propellants are stupid.

But PINK can be sold at every Toys R Us and Wal-Mart and shoppers' store in the country. You may get me laid after all.

Maybe, but the performance is impressive. And so is the white bright flame (which might be an even bigger selling feature).

In this session we also certified a Pro29-2G Skidmark motor with less than 62.5 grams of propellant (50 grams is the actual number). By increasing the average thrust to 80N, it still complies with NFPA.

No complaints here.

New propellant for CTI Heck Yes, I can't wait to try it. more choices for my cases! and reliable!!

Jeroen Purple is very hard to do. I have a purple formula it works well small, but big..... uh
The camera does not do it justice. But notice how purple the flame is..

Thanks again for the new choices, Now back to your thread!

Hate to say it, Mark, but that flame looks pink to me. Especially the fireball. But the color at least is perfectly OK in my book; it's, well, different.

So Jeroen, are you going to tell us where we can find vids of some firings of said propellants?

Is there a new updated motor list with the new motors?

Yes, I had it ready already. When I get in at the office, I'll post it at the usual place with some comments about the new products http://www.rocketryplanet....ms/showthread.php?t=4003.

Mark, it does have a pink tinge to it, the camera does not do the color justice!
like i said purple is hard to do.
Either way I like the PINK idea, I have flown many of them trying to make the purple work. It should be awesome for night flights! I have a pink crayon night flier that would be perfect for that!
