    Gorilla L789RT Question

    I have a Gorilla 3 grain L789RT that I was inspecting and getting ready to load up for a launch. The load come in 2 packages (1 of 2 & 2 of 2) The package that has 2 grains is marked with the Gorilla logo and data plate on the front of the cardboard tube. Inside are the 2 grains in a pink plastic sealed bag. The 2nd package (same cardboard tube, same data plate) has the other grain and all the o-rings and smoke grain. The pink plastic wrap on the single grain is marked (by hand with a marker) "WC" this tells me that I might have mis-matched grains?? Is this single grain a White Cloud Grain?? If anyone has one of these loads handy and could check to see if you have the same markings, please let me know. I cut open the 2 packages to see if the grains looked any different.... they really look the same to me. Same core size and propellant color looks to be the same. I can only hope that the "WC" means nothing, but I just want to be sure.

    It could just be a mislabeling. Maybe it's supposed to be pink!

    You can give Jim Harris a call, he's a cool guy, he'll help you out.

    Jason,

    I agree with your hunch; I suspect the "WC" marked grain to be a White Cloud grain. That said, both White Cloud and Red Lightning loads use the same geometry/nozzle, so it would work just fine; likely produce a more pink flame with a bit more smoke than typical with a red load. You like pink though, so load 'er up!

    When I have one or two pieces of extra propellant left over I seal them in bagging. I write on them what they are and they are placed in an airtight container. When I make another batch I remove them from the bagging and I just forgot to remove the WC from the bagging. When I sit down for the final bagging ONLY the same propellant is there on the table. You can test it out by removing a small sliver from each one and lighting them.

    Sorry for the confusion.
    Jim

    It wasn't marked on the grain. It was marked on the pink static bagging. It was just my mistake and forgot to remove the WC marking.

    Update.

    I cut off a sliver from the "mystery grain" and it burns bright RED. Thanks again, Jim for the quick response.

    ----UPDATE----


    Flew the motor yesterday. Worked great, took my 35 pound Gizmo XL to almost 4K. A little "chuffing" while coming up to pressure, other than that all was great. Will post pics and video later.

    Most definitely looking forward to the pics and video, sounds like it was an awesome flight!

    The chuffing made for some fun video. Please note the following video contains all the videos I took that day, but Griffin's Gizmo Xl flight starts at 7:50.

    Bummer I missed the launch! Every Gorilla Red I have flown using a standard "lighter" has chuffed for a while before coming up to pressure and leaving. Every Gorilla Red where I have installed Pyrodex pellets in advance has lit right away. They do take their time, don't they! Also, not sure if you used an AMW or Gorilla noz; I believe the Gorilla to have a slightly smaller throat.

    It looked to be a nice flight; thankfully it didn't JagerBOMB!

    I used a Copperhead, it should have lit just fine?

    I thought for sure you were going to make a surprise visit to "The Bong" last weekend, I stepped into Wilman's trailer and an N10,000 was just sitting on the shelf.....I got a little closer, and I swear, I heard it calling your name "Gus! Gus! Gus!"........oh wait, no that was just Manny in the trailer telling stories about his L3 flight. If he fails, Gus is going to make him sign up for another semester of GusHighPower 101

    I kept asking Tim if I could cheat in the MWP drag race....he said no. I hope I don't flunk the big test. Jeez, Gus is such a Hard@ss teacher, he gives SO much homework! He assigned one project where I had to build one carbon rocket (FROM SCRATCH!) kill it, then build another one, and kill it again. He gives essays almost every day in class, and pop quizes are a given. If I flunk the final, I don't know if I'll be able to do it again. If I do pass though, what class should I take next??? Now that's the question....

    Anything "N" by CTI calls my name......Still finishing off the Competitor 5 for the N5800 C-Star at Argonia..so, won't be up at "Der Bong" hit'n it hard for awhile still.

    The answer to what were going too do to Manny if he succeeds is simple.
    We take him to Olive Garden in Witchita...."Steak Gorgonzola on me young man!"

    If he fails.....Now i turn into "Uncle Vinny Scalapini."
    "You SCHMUCK youse....." We give him a week or so too dwell on it....then you, me and, the rest of the Chicago Rocket Mafia show up in his bedroom on a early weekend morning....say about 2am. (I really don't want to do this on a weekday-got to get his 'smarts' at school.)
    We gag him and, wrap him in a blanket....then it's off to Navy Pier.
    "You SCHMUCK youse times two.....how do you like your new Mud (think concrete) Jordan's?" "How dare you disgrace the F-A-M-I-L-Y?"
    Then....off he goes to sleep with the sturgeons......

    Bad news guys.....Anne STILL won't let me paint/letter up my Comp. 5 in the "Jews On Rocket Fuel (Team JORF)" motif.
    OY!

    Says she'll call her lawyer and, the Pope himself to get an annulment.
    OY!

    Dang! I even had "Rabbi Scott" ready to bless my rocket and, motor before Airfest.
    Oya-boya!

    Might be time too replace her with someone half her age that works at Victoria's Secret....

    I have a bunch of mixed feelings right now:

    1. Hunger, from the fact that Gus is going to buy me a big steak (a growing boy needs his meat)

    2. Fear, because anything that involves me being gagged in my sleep by ANYONE from CRM has me VERY worried.

    3. Sadness, that "Angry Anne" won't let you name your rocket JORF. It's okay Gus, Jenny has also disapproved of some of my rocket names....

    4. Joy, that Gus is going to start bringing a Victoria's Secret model to all the launches

    Gus,

    You do realize that Manny is still at the age where 2am is not quite bedtime........... I'd vote for 5 or 6am
