Sorry. Only so much room. I replaced with MHM 2012 pictures.

MikeS, the link to the pictures seems broken or changed?

Mike,I have a 96″ toroidal chute that DaveH used on his L3. Less than 15fps if you want to use it.Edward

Ooh, that’s a good name.

“StratosFear,” my L3 Intimidator-4, went 13,225 feet at Oktoberfest 2011 on an AeroTech M1297. Mike, there’s your solution to the 13k problem 😀

Nose cone is 1lb 15oz (i know i know 2lbs)

Mine will weigh in at about 26lbs, loaded at the pad.18lbs = Rocket with motor casing. no chute or cords.5.2lbs= Propellant3.0lbs to 4.0lbs= Chute, cords, electronics, nose weight.I will have two 72″ chutes that will have a decent rateof 15.65…   Read more»

The landing was perfect. No damage at all. Check the volumes of your airframe before looking at my charge numbers. I am flying a standard performance set up.Of note, 1/8 inch breather holes fore and aft main frames. Both located…   Read more»

If you get yours ready in time it’ll definitely be welcome!The more the merrier!

I am sure Mike appreciated your information, and I can say that I certainly do. Especially on the charges. You have just saved me a bunch of time. Now if I can get my contracts negotiated and signed this week,…   Read more»

at the last launch was my Intimidator 4.I got 7500 feet actual last launch on a K-510, CTI. That’s the two grainer. My first foray into 75mm. Of note Rock Sim set it at 8500 feet.Here was my flight prep…   Read more»

It seems my simulations are always short. I sure would like to get13000’My goal was two miles this year. Not having much luck.

Mike, I have been working on Intimidator 4 to be my L3 bird. We are doing much the same. Mine is zipper-less also, and the two foot piece above the fin can is now a 48″piece. I have added weight…   Read more»

I’ve had similar experiences. I built a PML Patriot for my L1 cert, and used the 30 minute epoxy. It used Quantum Tube and 1/16″ G-10, both pretty flexible. I also had problems with cracked fillets, even a chunk came…   Read more»

I’ve been using West Systems for over 20 years – first boats, then an airplane and extensively in rockets. I don’t use it to tack things though – takes too long to cure and in anything where there is heat…   Read more»

Steve is right in what he is writing. He likes Aeropoxy from Giant Leap, I am hooked on the West System. They make a five minute that I use for tacking fins on to hold them in place until the…   Read more»

Some quick cure epoxies are mediocre in terms of flexibility. I use Aeropoxy from Giant Leap.Pros:It flows nicely.It is elastic compared to some quick cure epoxies.It is really strong.ConsIt takes 4 hours to set up.Cures in 24 hours.I also make…   Read more»

I have been taught that before I start to build a glass kit, I wash everything in soapy water and rinse, then air dry to remove any mold release or anything else on the glass. Before I glue, I sand…   Read more»

Did you sand and rough up the G-10 and then clean it with alcohol before attempting to glue the fins? Did the root of the fins have the same treatment?I rough up everthing and cleaned the parts with 3 parts…   Read more»

My best advice is to really roughen the surface of the G-10 using 50-80 grit sand paper before the fillets are made. What is the body tube made out of and what epoxy are you using? I used Devcon, high…   Read more»
