FlisKits Big Honkin' Rocket

Jim Flis is up to his usual shenanigans again with this one. This "Big Honkin' Rocket" is a mere 3.25 inches tall, and weighs 1.3 grams (after heavy painting). The punchline comes when, at a club launch, you call for the heads up flight (so everyone can help you recover it) and announce that you're flying a Big Honkin' Rocket that in fact, can't likely be seen from more than about 50 feet away. Ever recovered an Estes Mosquito? Then step up to the challenge of flying and recovering a Big Honkin' Rocket!

Knowing how challenging it will be to recover these, you at least get materials to build a total of 3 of these for your $10.95, so the first two are for practice.

Odd'l Rockets: An Odd'l Parachute Endorsement!
A post from TRF: From Jerry - "I love using my well used/broken in 18" JonRocket parachute. There are no more memory fold lines. It's very soft and fluffy. Even the shroud lines are super soft from all the talc and not hard and whiskery. I have had dozens of flights with this chute and it just gets better like a well worn hat or shoes." Hi Jerry, That's good to hear! I designed those parachutes for JonRocket and BMS. They are also used in RSR amd Odd'l Rockets kits. My goal was to produce the best LPR parachute out there. The chute material is 1.5 mil thick, a bit thicker than most kit ...

Model Rocket Building: Centuri Draconian Marauder #5336 Build, Part 1, Parts
This one turned out to be one of the weirdest builds yet! The way the model was engineered was interesting but required some extra primer and sealing steps. If you were to just punch out the pieces, glue it together and paint it, you would end up with a model with many rough edges. I picked up two of these on Ebay for a very reasonable price. In the mid to late 1970s, many Centuri kits had die-cut card stock fins instead of balsa. These two had LOTS of layered card stock. Centuri called the Marauder fins "baffled, multi-layer" wings. Making a model like this out of balsa would have been ...

Rich's Rockets: Get this straight (Part 2)
Here’s a PDF cutting diagram. To the remarks on the diagram I’d add pretty much none of the dimensions are really critical. This is the sort of thing some people might be able to build out of scraps found in the garage, but I didn’t have what I needed so I spent somewhere under $20 ...
