Bernie,

Thanks for posting those pictures of the shock cord anchor.

These PS II E2X models use some of the same parts found in the original Pro Series II kits.

The molded launch lug used on the Nike Smoke and motor retainer ring system used on all the previous PS II kits are used with their E2X cousins.

There were two launch lugs on the Majestic but one was lost.

Default Majestic Body Tube

There wasn't much point in keeping the majority of the body tube so I cut that away. I plan to remove all the body tube to get to the motor mount/centering ring assembly.

Before I completely remove all the body tube I wanted to measure a few things.

The outside diameter of the Estes 2" tube measured 1.978" with a wall thickness of .030 inches.

Hmmm...

I took out a length of Quest T-50 body tube and measured it:

OD: 1.974"

Wall thickness: .028"

That's pretty close.

I decided to try inserting a Quest T-50 molded plastic nose cone in the remaining Majestic body tube.

It fit like a glove.

So, if you need a piece of 2" Estes body but can't find/get it, the Quest T-50 tubing is mighty close alternative.

In a nother day or so most of the Pro Series II parts will be listed on the Estes Web Site. Some are up there now. The parts should be available for purchase very soon I would guess.

What motor is to blame for the failed deployment?



This was a failed attempt to light a NON Black Powder motor that was in the upper stage. I even cheated and still didn't get that NON Black powder motor to light. With the new E16 or F15 motors in the upper stage, I've never had one NOT light. I'm sure one day it will happen when one doesn't light but for now I've had a 100% success rate.

To answer a couple of questions I've read. The shock cord in the kit will be a full 96" long. The Majestic Fins come preglued and are Chromed along with the Nose Cone. This is a NEW nose cone. The plastic Launch lugs are similar to the ones used on the Mega Der Red Max but are sized for the 2" OD tube. When assembled correctly and glued in place correctly I've never had a shock cord, or shock cord anchor come loost yet, "Knock on Wood". And yes a couple of these models along with some of the new 29mm BP motors should be in your favorite 40% coupon house in the near future.

Sorry, John - I forgot to mention the 8 foot shock cord length in my post. I guess I need to give myself a few lashes with one of the samples you sent home with me

That attempt to get that "NON Black Powder motor" to light as a sustainer did lead to an "interesting" flight from where I was standing.

Default Majestic Fin Unit

I managed to remove most of the body tube from the Majaestic fin unit.

John Boren told me he used CA adhesive to assemble these models. I have to say this unit is SOLID. There's no way I can disasseble the fin unit without breaking the parts and defeating the purpose of showing pictures of the individual parts.

Even so, things can be learned.

The 29mm motor mount tube is five inches long. There is a thrust ring at the forward end. Since the Estes E16/F15 motors have slightly shorter casings than the Estes (AeroTech) G40 and G80 motors a spacer ring will be available to use in rockets set up for the 29mm AP 'G' motors. This will fill in the gap when flying the same model with the E16/F15 motors. I don't know if the production PS II E2X kits will have their motor mounts set up to handle the G40/G80 motors but this Majestic model is set up for some serious 29mm AP 'G' motor flying.

The plastic centering rings have an outside ring 1/2" wide. The inside ring where the motor mount tube slides into is also around 1/2" wide. The web area which connects the two rings is thinner but still makes for an overall beefy centering ring.

The plastic fin tabs slide into notches in the rings and butt against the motor mount tube. A very strong and sturdy unit.

The plastic fins consist of two parts, a right and left side. If you have built the PS II Nike Smoke model then you would be aware the fins are hollow inside with ribs that strengthen the fins.

That wraps up my review of the parts and construction of these new PS II E2X models. I'll have some thoughts and comments in my next post.
