Applewhite 18mm Hourglass

[JAL3]

This rocket is one for which I had a build thread on the old TRF. I took it out to kill some time yesterday waiting for some people to show. I put a B6-0 in it, my biggest motor of the day, let let her fly. The video can be seen here: https://flickr.com/photos/23694991@N03/3204926926/in/set-72157612688256106/

When I got it back, I noticed that the shrouds were a little worse for wear and had broken loose from each other and from the foam bulkheads. The rocket was still flyable but would need to have the lug holes aligned before each flight.

I thought about using some epoxy to get everything back in place and make sure it does not come loose again but decided that was overkill and that I am too lazy. Instead, I lined everything up and then slathered on fillets of white glue.

When the glue had a chance to dry overnight, I turned the Hourglass over and did the same on the opposite side.

If this happened on a B6, than how much power do you think this can take without breaking apart? I like flying Art Applewhite's stuff on 18mm reloads, but I've never done it with an hourglass yet. Now I'm not sure if it will hold up.

This one has flown on a C6-0 and, once on a D21. I'm guessing that the joints were damaged either with the D and I didn't notice back then and/or it was exacerbated by bouncing around in a box for a while or that the damage came from bouncing off my drought stricken compacted base parking lot when landing this time. It was flyable again as it was but I wanted to work on it before forgetting (new years resolutions, etc.)

When properly built, I think it can probably take whatever you can stuff into it.

I've had several home made spool rockets and I've found the landings are a LOT harder on them then the flight.

The Tempus Fugit got another outing yesterday because Lindsey wanted to see it. It seems she is developing a taste for oddrocs.

It flew in high winds on a B6-0 and did just fine.

I used the hourglass to demonstrate tumble recovery and the propensity of rocket enthusiasts to make odd things fly while doing a demo for my church's Vacation Bible School. It was loaded with a C6-5 and took off straight, going into its normal wild gyrations about 3/4 of the way into the flight. It tumbled down on schedule and recovered without any damage.
