Estes recently released another model in the PSII E2X product line.

Named 'Mammoth' the model is taller than earlier PSII E2X kits. It features the same nose cone as the Majestic model without the chrome plating and the fins from the Prowler model.

The body tubes are finished in a shiny gold/copper metal wrap.

Looks like a straight-forward build.

Tell us the finished weight (and the usual extra info, such as letting us know if you used epoxy that added weight beyond the 'normal' amount).

I will post that information, Fred.

I do plan to add a long stuffer tube to the model. This will provide additional structural strength and allow me to use an AeroTech-like baffle system.

I wrapped up the construction of the new Estes PSII E2X Mammoth model today.

It's a tall one, over 59" tall.

I replaced the kit supplied 29mm motor tube with one that was 23" long. This improved the structural strength of the lower tube and allowed me to incorporate an AeroTech-like cooling mesh baffle system. It turns out that the Quest 29mm-2" centering rings that are used in several of the company's Advanced Rocketry kits fit just fine in the Estes 2" diameter body tubes.

I made an effort to use the epoxy sparingly in assembly of this model. The dry weight/mass of the model came in at 13.7 oz. The box lists 11.9 oz.

I will post pictures of the first flight.

Bob, nice job.

Quick question - where did you come across that 29mm stand? Looks like the same material that Q-Modeling made their stands from, but they're not around at present. Sure could use a few 29mm stands, if that's from a current vendor...

Thanks!

Thanks for the compliment, Dean.

I purchased two of these stands 3-5 years ago at a DART launch from Discount Rocketry. The price was $10.00 each. Jim of DR had the parts laser cut.

I just checked the Discount Rocketry website and could not find a listing for the stands.

Looks like it is under 500 grams with an F15 motor and well under with an E16 motor.

Post photos indeed since I will not be at the next SCRA launch. Going back north for almost 3 weeks. Work, work, work.....(and a lot of eating....)

Thanks anyway, Bob. Sure do wish a vendor would step forward with a set of 29mm stands...

Talk to me!

Check out Apogee or eRockets for the Northcoast Rocketry stands. There are two different types and they're both wonderful.
