    Fiberglass Lamination

    Hi - For various reasons that are unimportant, I am interested in laminating a LOC body tube ( 3" dia) with fiberglass. The tube is kraft paper that is then covered with a white paper covering. The question is - remove the white paper before laminating or not. If I peel that off, the...

    Aerotech 24/40 cases

    Looking for a couple - most people seem to be out of stock.

    Why use a motor mount tube?

    Thinking of ways to build a little differently in MPR regime. Is a motor mount tube really necessary? Centering rings can align the motor properly. Is there a big issue with the residual heat from the motor burn softening the adhesives?

    TARC Rocket in Carry on Luggage?

    So... heading to VA for the TARC finals with the school group that I have been mentoring. I have conflicting information about transporting rockets - in checked luggage vs in carry on luggage. Any experiences? The rockets are well used, so they do have BP residue on them. Hard to imagine...

    Grave Danger Fin Repair

    So... my Grave Danger had a bit of a rough landing and snapped off the tip of one fin. The fins are 1/8 inch plywood, TTW, and have my best fillets on them. Sigh. I have fashioned a replacement bit and glued it on - am currently in the process of sanding it to blend into the original fin...

    Madcow Super DX3 Mods

    So... Santa brought me my first HP kit, and I am puzzling over a few details as to how to build it. Santa was extra nice and got me the optional altimeter bay, and this is the source of my first stumpage. I'd like to build this to allow motor deploy, altimeter apogee only deploy, and...

    Play-Doh masking

    This was a totally strange idea that came to me as I was attempting to mask around an ACME launch lug. I really liked the red anodized finish, and I didn't want to get paint all over it but was totally flummoxed as to how I would cover it with masking tape. A simple solution was found in...

    Upscale Hi-Flier Question

    I have always loved the look of the Estes Hi-Flier, and since my last one was run over by a car(!), I've decided to do an upscale version. Based on my available components, this will be a 2.6X upscale and should fly acceptably on D,E, and F motors. ( I guess that this straddles the area...

    Baby Steps

    So.... I have a desire to creep toward dual deployment. I was looking around at my little rocket collection, and my eyes stopped on a Semroc Lil Hustler. This is perhaps my favorite model despite its propensity towards landing on other people's cars. My notion is this: 1) Get a dual...

    Timer vs Altimeter for Single Deploy

    So.... I'm thinking that I need some electronics in my rockets. I am using RMS24/40 motors for the most part and would like to be able to tinker with the parachute deployment times easily. (Motor ejection, while simple, seems a little limited and plagued by repeatability issues. I have not...

    RMS Motor Block Required?

    I was looking at an Aerotech 24/40 casing placed in an appropriate sized motor mount tube. It looks to me as though no motor block should be required since the aft closure is larger in diameter than the motor mount tube. Is this reasonable, or would this place too much stress on the threads...

    CTI vs Aerotech for 29mm

    I almost hesitate to ask the question, but can people please weigh in on the relative merits of Cesaroni vs Aerotech in the 29mm motor size? Specifically I am weighing the RMS29/40-120 vs the Pro29 starter kit. It appears to me that Aerotech consumables are less expensive, while the CTI...

    SEMROC Swift Failure

    I took another step up the learning curve today, but I'm not sure what I learned exactly. I build a SEMROC swift and took it out to Fiesta Island for a launch. The first launch was somewhat comical on a 1/2A6-2. Barely got into the air and then did a faceplant recovery. The second...

    How long can an RMS stay loaded?

    How long can a Aerotech reload stay.... loaded? I have a couple of 24/40 cases loaded with D15 reloads. I carefully loaded these in anticipation of a launch 4 weeks ago - what with the bad weather (in San Diego!) the launch never happened. I hate to disassemble these just to look at them...
