CTI Motor Adapters on the way?

[ONAWHIM]

I understand that CTI may be introducing a new product(s), 29mm adapters or spacers that would allow for using a smaller grain reload than what the hardware is capable. Perhaps a 3G motor could support 1&2G reloads, etc.
Kinda like the solution by others.

No real detail that I know of, just an answer to an email question from CTI.

Is this public knowledge?

The 38mm versions have been available for several months. I don't remember offhand if there are also 29mm ones, but it shouldn't be too hard to find out.

(does quick search)

Yup, here we go:

As I understand it; you can stack 2 grain spacers in one case. That gives you the flexibility of flying from 3 different cases in one.

Yep, they do. I have the 38mm one.

It makes it so you can fly twice as many reloads,while having half as many cases! and they are simple and easy to use.

There will be an announcement regarding these products soon from the certification body (CAR/MCC).

Eh? Our complete catalog? ;-) Your dealer will be happy.

Pro29 spacers were certified and are now available (give the dealers a week or so, please): https://www.rocketryplanet.com/content/view/3159/29/.

One spacer can be used for all motors, including the Pro29-6GXL. Up to two spacers can be used.

Hopefully the Green will turn up in some of the smaller Pro29 cases. Say the 3 or 4 grain size. Not to mention in Pro38 cases.

Nice work!

It will. We had to start somewhere. Since this cert session we made a lot of propellant. All ready to be certified.

Pardon me for being a bit dense
sometimes but does the 29mm spacer
make 6XL casing work with regular 6 grain
reloads ??

 

[JDcluster]

I read somewhere that the 29mm 6XL case is a full grain longer
hence: a regular spacer will work.
In essence you have a 7 grain 29mm motor.

That is correct. The Pro29-6GXL is really a Pro29-7G casing. But just to keep it consistent we named it XL.

I'm just wondering what to do with the next size up now. 6GXXL? 8G? ;-)

Jeroen

 

[stickershock23]

I have never removed the grains from an XL case, are their truly 7 grains? or just 6 grains that are as long as 7 grains would be? just curious.

Depends on what motor you are talking about. Most of them are 6 grains.

I think "6GXXL" would be fine. Rocketeers are very used to sizes like "XXL" and "XXXL", as I'm sure you've noticed by looking at the T-shirt pile at a major launch.

truth hurts!! :roll:

 

[AlphaHybrids]

Instead of 6GXXL go with 6GMagnum. Works for other products.

I think 29mm Maximum would sound cool. But if you then do a 9 grain you'll have another problem.

Pro29 turns one, CTI announces special 2010 promotion


https://www.rocketryplanet.com/content/view/3172/30/

The Pro29 special 2010 promotion consists of a Pro29-3G motor casing plus an aft closure ring, two Pro29 case spacers to allow you to fly Pro29 1G and 2G reloads kits in your 3G casing, a ProDAT Delay Adjustment Tool and a ProDAT centering ring for use with the ProDAT in the 29mm line of motors.

Using the supplied spacers, all eighteen Pro29-1G, 2G and 3G reload kits can be flown with this hardware package varying in total impulse from 41 Ns to 168 Ns, reflecting the equivalent of a Pro29/40-170 motor set.
