Hello, all, A quick question that normally wouldn't constitute it's own thread, but I have looked around for a while and can't find any answers. Has anyone used a PML 6" fiberglass nose cone and/or tail cone in 6" Blue Tube? If so, how does the OD of the bottom of the nose cone line up...

I finally pulled the trigger on a Tomach. I've been wanting to try a MD 54mm for a while, and I've had my eye on this kit. Now I have two things to build over my winter break, the Tomach and a 54mm tower to launch it.

Both. I joined NAR first for the Jr. Level One option. Tripoli introduced the TMP close enough to my 18th birthday that it really didn't matter. I waited and got my L2 with NAR and transferred that cert over when I joined Tripoli.

I started watching the ISS a few years ago and still do when I think to check for visible passes. My first time watching the station (with Discovery trailing behind shortly after undocking on STS-119) was the moment that pushed me towards where I am now; majoring in Aerospace Engineering.

I'm currently on vacation in Washington DC. After visiting the Udvar-Hazy center to see my favorite shuttle orbiter, I caught these on the DC metro bus from Dulles back into DC. It appears to be a Tu-154. "Yuri A. Gagarin Cosmonaut Training Center" is painted on both sides (one side in...

I figured it might be the Black Rock waiver for BALLS. Thanks for the clarification.

Where is AHPRA's 40k' waiver? All I can find on their website is a waiver to 8,500' with windows to 11k'.

The two-grain 29/40-120 loads have you tape the grains together to ensure the slots remain aligned while you prep the rocket so that you can get the igniter up to the forward end of the motor. The tape is consumed shortly after ignition.

"American special forces versus a Russian* farmer." *I had to guess at the "Russian" part, as my Russian/English dictionary (aka Google Translate) doesn't know what "rasyeskova" means, and it looks like a weird form of the adjective that I wouldn't have learned in 1st-year Russian.

This amateur video from further away gives a good view of the entire flight path. Zl12dXYcUTo Until the gimbaling goes nuts, it doesn't look much different from other Proton launch videos I've seen. Apparently Proton's abort mode is to simply shut down all engines, and for some reason...

Hello all, Does anybody know if the black "carbonite" fiberglass/graphite tubing that Wildman uses causes any attenuation/blocking of RF signals? Specifically, I'm looking to mount a BRB900 in my Wildman Dual-deploy's NC, and its' looking like somewhere down in the shoulder is the most...

My attempts at seeing the ISS are usually foiled by western Washington's ever-present cloud cover, but it is cool when it's actually visible. My favorite satellite siting ever was shortly after Discovery (my favorite orbiter) had undocked from the station after STS-119 (the mission that...

As far as models are concerned, five is the most I've seen. rfnDEryI3Dk

I received a helpful reply from BigRedBee within an hour of sending my message (We have the best customer service of any hobby!). While trying one of the proposed solutions, I figured out that my problem was simply me being an idiot and using the 3-pin "GPS programming" plug on the transmitter...

Only one com port shows up when I plug in the programming adapter (the same number regardless of which USB port I try). I do remember having to go through the operations in a certain order to get it to work. Unfortunately, this order still leads to a crash a few seconds after I click "read"...

Hello all, First, I apologize for dumping this question here, but I'm in a bit of a time crunch and I think I may get responses more quickly here than if I e-mail the manufacturer (which would be my normal course of action). I am preparing to fly a BRB 900 for tracking at a launch this...

SR-71 (never gonna happen) or a MiG-25 (could have happened up until a few years ago). rApXqj6WS2E As you probably guessed, I like the whole "mach 3+ at obscenely-high altitudes" thing. If I ever have a spare $21,000 to spend, I'm buying myself a MiG-29 ride to 70k'. It's 20k' and a whole mach...

I have thought to myself that by collecting the elements, I am vicariously collecting everything in the universe there is to be collected... including hot Chinese mustard. Thank you. I'm glad to see someone besides me is getting a kick out of it. I hope to get more pages up soon (if you...

I have an on-and-off side hobby of collecting the elements of the periodic table. Of the 118 known elements, 95 of them can be represented in a collection in some way (by "in some way", I mean "this rock may contain an atom or two of francium every few years or so"). It was rather surprising how...

I grabbed the linked document a while ago from a location I have since forgotten. It talks about composite-to-BP staging by leaving out the ejection charge of a reloadable booster and using the delay grain to light a strand of pyrogen (the author used the heads of Copperheads as well as...
