Welcome!

As long as the motor can lift it, safely fly and deploy the recovery system, then "Yes". Most folks don't use it because the paper variety of tubes are typically lighter, so you can fly...

Yes! My favs are the jug taxiing, swinging the big Ham Standard and the P-38 in flight (tight, clean lines).

Those are great pics (like calendar grade) TALON! Are these from a DSLR?

Love, the 6 o'clock view of the F-22 with the heat plumes. :dark:

For many consumer products, there is a Material Safety Data Sheet, that explains the dangers (or lack thereof) with the product.

Here is the MSDS for this product:

VERY cool plan!

Maybe a keychain cam in one of the boxes to see her expression?

Greg

Sure!

I have now idea how you did this so please post.

You ask very good questions, but unfortunately the answers are somewhat elusive.

The properties of metals are known and are fairly constant. The problem with layups is that they are not isotropic...

Great pic and back-story!

So I have to ask: Does your son wear the hat on impulse? :)

About 8 years ago, I was in Paris on a business trip. Coincidentally, the trip was timed during the Paris Air Show. A work colleague and I had a day off, so we decided to go to Le Bourget to see...

A first look here on the 1/32nd scale B-17:

Wow, John!

That. Is. Epic.

It will be a tad bumpy starting out, but after a while you will hit your stride.

What is fun is when they are older, and if/when you go to a McDonald's play place, your kids will kind of take it...

Congrats!

And I welcome you to the club for those who no longer parent "man to man coverage" but are on "zone defense". :D

It does depend on the rocket, and how you define "safe". Does safe mean wrt to those on the ground, or wrt to the rocket, itself?

Also, if the chute "snaps" open, that puts a considerable load on...

Fascinating look at projectile impacts using high-speed videography.

Any spackle that is water-based can potentially warp fins. My guess is that spackle may be prone to cracking, more so than other solutions.

I'm so glad that the website is not www.enginecato.org. :wink:

You might remember this story from the news a few years back ...

I had one. I was supposed to get it at Christmas (either '69 or '70), but "Santa" wrote me in a note ( and his handwriting was curiously like that of my dad's) that none were available and one would...

I don't have a 0.01 g resolution scale.

Hmmm ... these might come in handy for some things.

Thanks for posting these.

Greg

Yes, you get better consistency if you weigh per the manufacturer's recommended ratios.

Two things are required for a good epoxy join (actually a few more, but for now just two):



Proper...

I like/prefer Ohaus digital scales. I have 2, one with 0.1 g resolution and one with 1 g resolution. For small batches of epoxy, you need the 0.1 g resolution.

Nice!

PM sent, sir.

Thanks for that input CJ. It's good to know that I am getting closer to my goal.

I hadn't considered that my launch system may not have been a good analog for a club system. So I may do another...

In most caes, context is everything regarding symbols.

Regardless of the context, they are forbidden by law in Germany.

You want to move to a state with a rich history and no state income tax, like Texas.
