...and you can always swap in a single use Aerotech D10 engine if you want to send her higher... :wink:

I took a day off to launch a few. The winds were a bit high so I was careful not to put anything too high up. And two school busses full of kids swamped the park right after I got set up. But I got...

The stuff is based in lacquer thinner or MEK or something potent like that. Super stinky and not for indoor use unless you have a serious fan and air extractor.

I got a chance to launch her when I attended the AMOREA launch on the east side of Indianapolis last Sunday.

While I didn't get video, I did shoot stills. I'm still learning the ins and outs of my...

I'm curious about how people use the forum that this becomes an issue. I just never go into the news feed sub forum, and am blissfully ignorant about whatever goes on in there.

In what manner do...

Sounds like a great idea!

meanwhile, I did a close examination of the ringfin and found the smoking gun. A section of it had two small cuts and the section between was sort of pulled out. This is...

The molding and trim glue is still sold at most ACE stores, at least near me. If anyone is looking for the product, check an ACE Hardware.

I dealt with an issue like this last summer. I had bought a nice new launch rod that was exactly 3/16" and it seemed tighter than my regular Estes 3/16. Several models felt like they would certainly...

It's funny... I was the "teamwork filler inventor" but after a few months moved on to using CA to seal, then regular spot/glazing putty (sometimes thinned with lacquer thinner). I found the teamwork...

The full-scale SS Cassiopeia had a rough first flight. :(

Frankly, the flight was doomed, apparently.

Now, keep in mind this design is inherently stable. I've simmed a few scales of it and get...

PRint ruler image onto label paper, stick to wood?

I'm pretty sure staging is supposed to occur NOSE-UP instead of NOSE-DOWN as shown.

From close examination of the original pictures, I can tell:

-At the time of the picture, the sustainer motor...

Hi folks,

I had the pleasure of flying today with the folks from the AMOREA club, on the east side of Indianapolis. The weather was great and the winds were light.

One of the flights was the...

I sawn this on NF streaming some time back. The movie was really interesting and I've been planning to watch it again to see if I can pick up some more detail and deconvolute it a bit.

I was...

Congratulations!

Nice next project. What motor will that oddroc take to fly?

Here's a close up after removing the tape and allowing some Molding and Trim glue fillets to dry:

The ringfin was glued on with carpenter's wood glue and filleted with Titebond molding...

I only wish I knew who I stole the idea from. I built mine after seeing a similar contraption here on the forum. Kudos to whoever first thought this up... :clap:

And when not using them on rockets, they make great Klingon emblems...

Very nice. I really must finish the one my boy started with me 2 years ago!

For completeness, here is a picture of mine. I've made many dozens of cuts with it, from BT-5 to BT-80.

A steady hand rolling the tube gently against the blade, and inside some support like a...

No worries. Looks like a good flight on A3-4T, though the Rocksim file doesn't include some draggy elements and you may find the delay is a bit long.

Next up: Attach the fins.

What can I...

Without the razor blade it takes a long time to cut the tube... :wink:

Found it with Google on my phone. I didn't post pics but others did:

I am at work so can't post pictures, but I made a jiggy thing for cutting tubes that works great with clear tubes as well as paper tubes.

Imagine two 1x3" boards about 18 inches long, screwed...

Let' start an accuracy versus precision debate! :grin:

Meanwhile, I cut fins based on my "freehand-designed adjusted downscale fin template" as printed out from Rocksim.

The fins are made out of two pieces of wood, just like the original, butt-end...

When putting on the rear outer body tube, I was worried about glue getting into the area where the motor would be, so I used one of those engine block marking guide tubes as a protector. I inserted...
