Strong work:headbang::headbang:

I have only been a NAR member for a couple of years, and I really enjoy the Sport Rocketry Magazine. Ironically on the page only three pages BEFORE a great article on safety, page 31 announces a...

Will try all three. Thanks !

I use the plastic tubes discarded from biopsy needles (the tubes are removed BEFORE the needles are used, for anyone wondering:tongue:) for launch lugs. They are super strong and kind of inherently...

I have no problem with a certain amount of severity to get the point across. Short suspension and a long essay (very critically graded and returned if not satisfactory until it IS satisfactory) on...

I seem to remember a post from HCMBANJO regarding issues with pre finishing fins. If I remember correctly, fill and finish does NOT cause any problems with fin adhesion as it is porous. PRIMER...

Thanks. I definitely needed a smile today! This helped.

Yeah I would say that's a bit off topi--"SQUIRREL!!!,"

That's helpful. THANX!

When is clear coating better than Future and vice versa?

What about clear coating to protect decals? Should you wait 48 hours after the waterside decals are on? Do you do the clear coat in multiple light coats or one wet one? I am assuming that sanding...

As he says, make sure you do BOTH sides of the balsa at the same time, otherwise it will warp.

I have done something like this with the Double or nothin...

I have done the opposite--- one C motor to successfully ignite 3 A10-3T motors. Used a ducted system ---basically draped 3 BT5s over the BT20, with a short gap to allow the extra gases to vent. ...

I kept flunking bedside manner. Hence my current job as a radiologist. Ah well.....

Probably there are some examples of more extreme asymmetric fins, but these are my examples. They required no extra nose weight, but they are fairly long (18") body tubes with...

Retrospectively on the off chance you DID have an untoward event, this or similar names is going to look really bad on the insurance paperwork.....

I liked the Current Estes Flutter By. Review here

I have some kevlar thread, if that is what you need. PM me an address and I will snail mail it.

It's my fault. I just put in a sprinkler system. Gonna be the wettest year on record for Tennessee.

For the history buffs out there, how did the Apollo missions keep the chutes from tangling, and how many chutes could have failed and still been survivable?

Okay, how about this:


two engine cluster. Two separate body tubes and nose cones and chutes. Body tubes side by side. One tube carries a c6-3 and has a very long shock cord and deploys...

Still playing with stabilizing video cams on descent. Was thinking with two chutes attached 180 degrees apart to body would probably not have as much spin. Anybody played with this? Any tips on...

Depends on winds. However, with winds under 10 mph, firing straight up (no rod angle), should probably be within 50 yards of the pads (probably much closer.)

How big is your field? You should...

Godspeed and welcome home

Two things that tend to be forgotten at rocket launches, which tend to be (hopefully) sunny day events where everybody is looking upward for most of the day:

Hats and Sunscreen!

Lots of good answers. Not sure if mine is correct, but for those of you who said "Sunburn", that is the one I was thinking of.

What, sunburn? Potentially fatal? Absolutely. Invasive...

Below is my experience recently. But specific suggestions as follows for the safety inspector:

Bring a little "packing stick". I use a 1/4" dowel with 3 rounded toothpicks projecting forward. ...

This is actually a serious question. I think I know the answer, but figured I would open it to other guesses. Something to think about as the rocketry season in the Northern Hemisphere kicks into...

I thought "right to work" state specifically referred to whether you could be forced to join and maintain membership in a union as a requirement to have a job at a specific company or factory. There...

Odd'l Rockets has something called the Birdie which should be a pretty good all weather all surface featherweight recovery for small fields.

The thing is basically a Badminton Shuttlecock with an...
