    Aerotech cases

    Going to be shooting clusters and looking for someone that sells motor sets for economical prices. Looking to buy at least 4 to start.

    Fiberglassing wraps

    I have a Saturn V transition that is cardstock that has a wrap on it. Can you glass the back of the wrap? I figure if I'm careful, I'm thinking I can reinforce the wrap so I dont need to use spray on adhessive... I don't really like it much.

    Alternate sled mounting

    I have a project where all-thread or any sort of railing is going to be problem. One of the bulkheads I cannot drill into without the potential of damaging the part. The part will be sealed completely and will be epoxied in place. The lower part of the makeshift e-bay will have a bulkhead to...

    Sirius Saturn V instructions

    Anyone have a copy of the Sirius Saturn V they could either IM me or post? Mine have walked off

    Turning something unintentional into something good

    I have a baffle that didn't quite come out the way I wanted it. The baffle utilizes a coupler, two bulkheads, and a MMT. The idea is to have the gasses would come up the MMT which should be centered on the lower bulkhead. The top bulkhead has holes on the outside forcing the gasses to bounce off...

    Q-Jet uses

    I've been waiting for folks to put more of these in the field before buying any. Has anyone found an instance where the Q-Jet's just stepped it up a notch? I'm not talking about sticking a D16 in Hi-Flyer or some other minimum diameter rocket and wish it luck. Just wondering if this changed...

    Resin and temperature

    Anyone have any idea at what temperature resin cast parts start to have problems? I'm seeing conflicting information. I'm certain it varies by manufacturer but I'm sure there is a rule of thumb of "Do not exceed XXX temperature". Any feedback is appreciated :)

    Plugging MMT

    Anyone have a clean and effective way to plug unused MMTs when launching clusters with empty MMTs?

    Semi accurate aerodynamic simulation

    I have used RockSim for years now and think I may have come to its limit as far as... unusual experiments. I like how you can see things like differences in drag based on speed as well as optimal weight calculation. I want to experiment with different shapes that RockSim cannot simulate or I'm...

    Mach 2 with min diameter

    I see folks like to tip to tip their surface mounted fins when the feet the minimum diameter rockets faster than mach 1. My project is a Go Devil 38 which will be using a fly away rail guide. I'm debating on using the nose cone E-Bay so I can shorten the length to one body tube. Now the...

    Refurbishing my SV

    After multiple flights, my Estes Saturn V finally had an internal failure of the centering rings. I think it was too much ejection charge or the upper stage was on too snug. Either way, motor mount assembly is toast. While looking at replacements and opportunities to make it better, I noticed...

    Fiberglass imperfections

    Started building my WM 2 stage rocket and came across some odd cuts. Fortunately they didn't cut enough off rather than cut too much. Imperfections are about the diameter of a nickel and as high as 3/16". Was thinking of using my Dremel but not sure if I will cut it straight. Saw blades will...

    Name this rocket

    Was going through my high power stuff when I found this. Anyone have any idea who made it?

    Extremely small space for parachute

    Hey all. Finally ready to build my HPR min diameter bird and had a concern. Rocket: 54mm min diameter. The nosecone coupler is the e-bay, the biggest engine will almost literally rest on the bottom bulkhead. The volume between the nose cone tip and the top e-bay bulkhead will house the shock...

    Ultimate Buzz build

    This is a variant of the LOC Mystic Buzz which I asked LOC to modify for me. It is a 4FN, 5x29mm rocket with a baffle for the center coupler that splits in half during parachute recovery for zipperless deployment. LOC also went with a single fin design which has the center tab flush with the...

    Gluing clusters

    Hey all. About to start my cluster build today and was looking for some input. I'm going to be clustering 29mm MMT's together which normally I wouldn't give a second thought to using wood glue on 29mm MMT's. But since the total impulse of all of the engines will be going into I-J impulse range...

    54mm fin cans

    Hey all. I came across 6' of Hawk Mountain 54mm fiberglass tubing I bought awhile back. Also found an Acme fincan that Giant Leap lightened up. Just need a good nosecone and a motor retainer to make an easy semi-bullet proof minimum diameter rocket project. Only thing I have no idea how well the...

    Using data

    I've been debating about getting a Jolly Logic AltimeterThree for about a week now as I want a easy to deploy altimeter that gives me data. AltimeterTwo gives me some good data that I would like to see (big enough chute, how accurate sims are, etc). What I'm curious about is whether or not the...

    How to accurately bevel fins

    I have a project in the works that will have some nice thick birch fins. I'd like to put a nice bevel on them but I'm trying to figure out how to do it consistently as it has 4 fins that split. Is there a jig or tool out there that makes this something that is reproducible? I'm not a huge...
