Hello. To get started in model rocketry you need three things 1: Rocket 2: Motor 3: Launch system (pad and controller) For 17 USD (+shipping) you can get this: https://www.hobbylinc.com/htm/est/est1497.htm For a bit less you can build your launch system...

How about just calling the tab "Motors"? (keep is simple) It is, after all, all about motors, ejection and staging. It did take a moment to get used to, but I see the benefit. It allows you to make all of the changes that pertain to motors in one tab. For an "Alpha", it's not an improvement (and...

I saw that as well... WEIRD! My other question was "Who's running the camera?". Ignoring the the sound-on-the-moon issued, it's possible the creature felt the vibrations of the fart through his feet. The saddest part is that the people who deny we ever landed on the moon will soon have a...

Jake, Try this. find the Barrowman equations and work it out "by hand", and compare those results to the cut-out and to OR. https://my.execpc.com/~culp/rockets/Barrowman.html (there is also a spreadsheet to do the math for you farther down the page). See what you get. I really don't know why...

Hey, Jake. Open Rocket is a pretty good piece of software, but it looks like your still coming up to speed with it. I'm going to assume that the mass item at the front is the actual nose cone weight, since yours says it's made out of office paper. I'm also guessing that the mass item at the...

Estes Starblazer X-20. First flown July 1981 in Billings, Montana, lost August 1982 in Midland, Michigan.

It's HOME! Looks like old Grand Rapids is getting a little snow. Gonna be freezing down here (Atlanta) tonight. By that, I mean +27 F. Michigan is where God tests the faithful.

Somewhere I have pictures of the launch I attended in Michigan. It was chilly (about +10 f) and there was a little over a foot of snow on the ground - deeper than a few of my rockets were tall.. Turnout was actually pretty good! Mostly it was High-Power, but I flew 18 and 24mm just the same (I...

Uhm... XP-56? I think a P-38 would ave to use the canted twin motors mentioned earlier. Mounted in the cockpit pod pointing slightly above and below the H-Stab.

Lots of opinions here. I guess I'll put in my two cents Estes Alpha III starter kit Estes Silver Arrow starter kit Both can fly on A8-3 motors an not go out of sight. Get them at Hobbylinc or go to Hobby Lobby with the magic 40% off coupon.

Or get an Estes E-Launch Controller, designed for "E" motors with longer (30 ft), larger gauge leads. I like mine quite a bit. Modified with an drop-in LED continuity light so it won't light off Quest ignitors until you press the launch button". The thing is simple and robust. For those who may...

That is one excellent paint job! A rocket that need not hide in the basement or closet. But... I wonder if you may be tempting fate by 1) having so much work on something that could end up in a tree, and 2) painting something that could end up in a tree, with a tree theme.

My dad lives in rural Michigan. He an his neighbor have "Nuisance Permits" - basically a renewable 6-deer tag. Venison steaks, sausage, burgers, stew, summer sausage... yeah, it's all good. If only he could get a nuisance duck permit...

Northrop N-9M North American X-15 Martin X-24B

Hopefully a few did stop payment on the checks. And it is completely messed up.

Here in Atlanta, an entire apt complex got evicted with 48 hrs notice - right after they paid rent for the month. NOT the fault of the landlord (not directly anyway) - then entire complex was condemned for not having heat, by local gov't. So on a week of record warm temps (70ish), these folks...

A booster motor will create enough pressure out the front to blow the case clear of a rocket. I know that from experience. The problem is it also blows out a bunch of hot, burning globs of propellant which can burn your rocket. Packing the end with some "Dog Barf" does a fair job of eliminating...

NAR United States Model Rocket Sporting Code (Pink Book), 2011 edition, page 1 section 3.4 "Stages" "There shall be no more than three consecutively fired stages. The staged configuration of the model is considered to be that of the model at the instant of first motion on the launcher. " So...

WOW! Awesome story! I have had a few days like that. Glad you got the screws out. STRIPPED SCREWS? That's some serous quality control About your Nephew: He sounds like every good mechanic I've ever met. As a Diesel Mechanic, can he work on Railroad Locomotives? That would be a pretty cool...

Whoa, whoa, whoa.... Wait! I used to actually repair Dyers in a previous life -- and airplanes...[shrug] If you posted something here that is the same as what I post - I am agreeing with you. 1: Reed & Prince screws are pointy, Phillips are kinda blunt. 2: Use the correctly sized Phillips...
