Not a real big fan of CTI stuff but some of these long burns show some real potential the I-55 looks very neat, little over 5 seconds at full power. With enough spike at start up to get you off the pad, not bad not bad at all.

When will be able to order these motors and the new 2-grain 24mm case?

Now. First motors have shipped already. Check with your dealer.

I checked the pro29 instructions and it does not look like it but can anyone confirm for sure whether the 29mm 6GXL reloads protrude forward from the case or are level with the front of the case. I would like to double check what space I need to leave behind a bulkhead before I put it in.

Thanks

I don't know if the Mellow bulkheads protrude in 29mm, should they release a 6gxl one, but normal ones barely stick out.

I am considering this, but am also considering traditional AeroPac type retainer on aft end and need a place for recovery harness. A number of threads seem to indicate that this is possible. I can't seem to find them listed anywhere. Any suggestions would be appreciated. Thanks.

Yes! It's a plugged closure.
Not sure of the price though.
It's included with the K300 load.

Sorry to bump an old post. Is this to say that only the plugged Pro54 forward closures are tapped to take the Aero Pack CTI MD adapter? I figured the locating pin on the adapter was used to "plug" the charge well channel and that it would work in any Pro54 load.

The adapter is for normal forward bulkheads. The K300 bulkhead is 1/4-20 tapped, and needs a different adapter to the 5/8 thread.

I was under the same impression as matthew using the Aero Pack CTI MD adapter on all CTI 54mm reloads. I have the Aero Pack MD retainer and CTI MD adapter. How do I know which loads I can use the adapter with when ordering reloads ( using Wildman)? Specifically interested in the 6G K260 and new K711. Another question I have been facing before installing the MD retainer is how far past case does the installed adapter protrude?

Thanks in advance.

Does anyone have better descriptions for the CTI propellants than what's given on the pro38 website? https://www.pro38.com/propellant.php

As a vendor I would've thought they'd do more selling on this page, similar to what Aerotech has listed on their site. Before I get flamed, I do know that a lot can be learned from the motor designations (pertaining to burn time, etc), but a bit of marketing wouldn't hurt!

CTI is a manufacturer. Not a vendor. I do think better cataloging of new propellant formulas and motors should be done on their site, and not here on the forum. Just search for the propellant or motor you are looking for and chances are that someone here has flown it and has a picture posted.

Ultimate Wildman named "High Anxiety" on a CTI N1800 White (4G 98mm) at URRF 2. 12,351 ft of altitude and 1140 fps airspeed. This is a great motor, and the biggest I can fly until I can afford a 6XL case

The Mellow forward closures are a bit longer than the regular closures for Pro29 and Pro38. The Pro29 delay well sticks out 0.3" from the end of the case. The Pro38 is 0.5" longer. Updated drawings will be available on our web page in the next few days.

The locating pin is only used to center the adapter. The pin will fit loosely in the threaded opening of the tapped forward closures. There is no problem using the Aero Pack CTI MD adapter with the tapped forward closures. However, you can also screw directly into the threaded opening of the closure.

Thanks, Jeroen. So, to make sure I've got it straight, I can use the Aero Pack MD CTI adapter with any Pro54 load? The main game for my upcoming project will be the plugged 6GXL loads, but I'd like to use the Aero Pack MD extension rods with shorter cases.

Correct. The MD adapter is self-tapping into the ejection charge well. All reloads use the same geometry.

Thanks for the clarification. How much if any overhang of the adapter past the casing should be accounted for when using the 54mm MD adapter? Should the same 0.6 be used as in the attached drawing?

Thanks for the images. I have been considering opening a load just to get an idea of what it looks like finished, but these pictures answer my question, much appreciated.

I just built one of the new N5600's (while using LOTS of Gorilla Glue) that I will be flying on Saturday. I really like the new cardboard ignitor holders, a big improvement over the old plastic ones.

The 98 one is missing the 4 inch outer dimension of the boat tail.

Thanks Jeroen, I queried Sunward Aerospace about this last week. Are these available for purchase at this time?

Thanks; same OD as the retaining ring on the case (will be updated on the drawing we will post on the web site).

Jeroen,

Do you guys have any plans of making a 24mm 6 grain mellow in the future?

wfcook · Jul 30, 2014

I've posted this elsewhere, but I am very proud of it (almost insufferably so), so I am posting it here, too :blush:.
