I don't think it will add too much weight, but I hadn't actually calculated for it, so I'm going with negligible weight..
Flight photos pleaseI started to panic, as I contacted Ken from Performance hobbies about a motor, and due to no one flying his stock of 29mm H and I is none. He has a G76-G, which at my rocket's weight sims to just over 450 feet, just barely fast enough leaving the rail. I had to go through my own inventory, thinking I might already have a G76, and I discoverd an H180W, which was my first choice for first flight, sims to just over 1300 feet.
That's the plan...Flight photos please
I am very appreciative of all the support given for those inlets. I think it makes the rocket really pop!It really did come out great. Love the silver on those inlets (and happy to have lent a hand!)
The cord broke- I'm pretty sure I had too much charge for the tube size, which I believe helped torch the chute... I used 3/4 of what came with the motor, 1/2 of what comes with it would be more appropriate for the 2.6"... I might have to start real measuring at some point. I think the combination of it being to short, a bit too powerful charge, and a heavy nose cone was too much for that nylon cord. I will be replacing it with some kevlar, and will probably triple the length.I'm not following did the shock cord break or did you have the pieces come down on separate chutes? Looks like that one chute really got torched?
Good solutions, but why not just have the nose and aft section come down with separate chutes? I like Madcow kits and have built plenty, but not real fond of the supplied recovery harness. Thats the first thing I change out and the flat chute that comes with the kit.The cord broke- I'm pretty sure I had too much charge for the tube size, which I believe helped torch the chute...

I'm guessing my launch video file is simply too large to just upload as it just errors out. I would still like to share it, any best method for sharing video here?
One would think it shouldn't take a rocket scientist to figure that out...I think that the easiest thing to do is first upload it to a video sharing website, such as youtube or vimeo, and then post the link here.
The trees line a creek, with a nice pond in the other direction as well. We don't have a lot of options right outside of Washington D.C.... I have yet to lose any rockets there, but have certainly come closeWell, you nailed the “up” part. Great boost.
A 6’ shock cord is definitely a bit short to my way of thinking. If it were my bird, I’d be looking at something around 12-15 feet long with the chute attached at about the 2/3 point (8-10’).
It’s a shame about the laundry having to be replaced but that’s simply a matter of sending money out rather than making rocket repairs.
Nice launch site but the trees make me nervous.
That was an AT H180 WT with 8 second delay.Nice boost, what motor was that?
Honesty, appreciated!FYI, I've broken more shock cords than I care to admit and each time I make the same observation and conclusion you did.....I still can't bring myself to lessen the charge. Mine have mostly happened with 38mm tubes. I'll get it sorted out one day!
