What did you do rocket wise today?

[JoeFilgas]

Got my Apogee Components Convair MX-774B HIROC finish primed and wet sanded! Ready for gloss white base coat tomorrow!

 

[Hobie1dog]

more sanding of primer

Ok, here is what I pulled out of the box. When these came out I had the "Dagger".
I saw this early this week on Amazon only 1 left for $22 and had to get it.

But now the box that has been been unboxed, needs to to have the box unboxed !

I have no idea why I am so interested in that rocket. But I have a plan to clone it in ST-10 with a 3D printed NC.

If you are looking for another chunk of that airframe, the Dragonite at Hobby Lobby still uses it. And it's even pre-colored black.

 

[SolarYellow]

Launched at Lucerne Lake with my godson. Two on my BT-60, four on a new "Short Ranger" built from a Hobby Lobby clearance kit. Left the fins in take-down mode to make it a "travel rocket." Will post up some build notes when I have time.

No mosquitos there. Straight smoke and short walks. It was a good day.

Mail call!!!
Opened this order from Ollie Oop Rocketry I received Saturday.

Not sure if I will build or clone (somehow) in the near future.

Opinions welcome.

Sanded on filler, sanded on filler, again.

Sent off the altimeter I've been designing for manufacture. Nothing too fancy, just a logging altimeter with peak read out via flashing LED. I went over and over the design specs and have a folder with about 8 entirely different designs as I tried to balance desires, ambition, practicality and cost.

Final (prototype) altimeter is 15x28mm including shock cord mount and should weigh in at about 3g with battery (TBC). It has built in USB for easy download of flight data and charging the built in battery. My normal experience is that every Rev 1 board will need at least one bodge, but I'll not find out what it is till they arrive.

I didn't feel like soldering the 0.45mm pitch QFN packages, hence choosing to have them manufactured. It's almost cheaper than me buying all the parts and doing it myself these days as well.

I have a friend helping with the firmware this time which is nice. I can do firmware in a pinch, but I never enjoy it as much as the hardware design.

I'll post photos when they arrive.

A rocket kit called "Cruise Missile" just seems like tempting fate.

Searching some tubes in my Stash, I found an ST-13 in 18". Great for using with my newly found AstroCam 110 that had the blue tube in the bag* These BT-56/ST13s have become Unobtainable. What erks me is about 12 years ago I had a 34" long BT-56/ST13 with an Eliminator plastic fin can and the Bt-56 sized Eggs-Press [EnerJet EggCrate] Nose Capsule on it in my Electronics Lab.

I don't know where that tube has gone to. The Egg Nose I sold here about a month about but have not yet found that tube. Just one place left to look...

* I want to make this like the White AstroCam 110 that @K'Tesh posted in his OR files.

 

[Art Upton]

And another thing, remember I found the ACE PNC-39 Nose Cones looking for Photon Probes I had?

Well lookin' for an ST-13 tube I found the Photon Probes and a New in Bag "Spare" Eggs-Press kit with the EggCrate nose capsule

 

[SolarYellow]

I currently have a PNC-56 flying nicely in BT-55. Used a big flat file to eliminate the tensioning lines from the shoulder and just a little further diameter reduction, but it fits nicely enough with the humidity here in Houston. The OD mismatch isn't noticeable at 15 feet, and wouldn't be a big deal with a camera wart hanging off the side.

In the desert, I reckon the BT-55 would shrink and it might not be such a nice fit.

Continued working on a Red Nova scratch build, with 3D-printed nose cone designed by @Jack Hydrazine, papered balsa fins, and Cricut-cut adhesive vinyl markings. Nearing completion. An enjoyable build.

More glider progress.


I spent a lot more time on the glider than the instructions suggest. I sanded a nice airfoil into the delta wing, reducing the thickness by half from front to back. Then got out the razor plane and carved the leading edge. I put my practice with J&H kits to use.

 

[RocketTree]

Flying Nose Cone 5.5" is almost finished.





Got some new shelving for the rocket room. Nice to have them displayed without the clutter.

I worked on my list of 10 rockets I have in progress and what names are going on them, in what style of font, and the color of each rocket.

 

[CPO Fast Forward]

FInished putting together a Mini-A-Heli and picked up a package from my front step:

FInished putting together a Mini-A-Heli and picked up a package from my front step:

Putting the ideas for Tazz (a Gyroc configuration) and the Mini A Heli (a Rotaroc configuration) together: once upon a time I made a 3-finned Gyroc-style rocket but with the spin tabs extended into full-fledged rotor blades that trailed behind the rocket during boost. Worked nicely!

Always nice to be able to use proven concepts to extend your rocket fleet and skills.
So far my scratch building skills extend to cloning, but I was able to put this together from old Centuri plans:

I keep telling myself that this is going to be the last one. 7 Interceptors later.....

Found an old image, tried to edit it to make the configuration more evident:

Elastic pulled the blades into helicopter mode. During boost they were held back by strings that ran to the nose cone shoulder, such that a nose blow released them.

Nice build. My STEM kids were looking at the small scale of this (Estes) I think. I had all my kits put for them to look at while they built their Alpha IIIs. I Lille the larger scale here.

 

[seabeeadp]

Well today was finishing up day 3 with the kids (5-8th grade with “Introducing to Model Rocketry. Needless to say I can’t be a teacher. . I love these kids. Instructions were simple. “listen to me and read the instructions with the rocket and don’t take short cuts.

End of the day I was “Dr Rocket Repair”. How these kids mandate to do what they did—/. Salvaged them. But wow.

The stick coming out is my version of security for a thrust ring as this was the fin assembly wifh the hook in an angle and twisted. It’ll be safe. Just gotta make sure the body tube is secured ok.

And the broken Fins. Think I’m sticking to kits made in the USA

We launch on Friday. Safety check first Range Rules and they WILL initial the NAR code and show to me before launching

I enjoy it though. Waiting to hear from Estes now about my 1/200 scale Saturn V. NIB and fin was cracked. Love to see stuff made in the USA again.

I built a saucer with a 38mm motor mount and adapters down to 24.

 

[goose_in_co]

Got a box from Fliskits today.



I really like all of the unique designs that they have.

 

[Cape Byron]

Slapped on some vinyl leftovers, threw in the nose weight. Not too shabby (from some angles).

Under 75 grams, which is good.

When you are laying down the second line of Tamiya tape and pull it off a bit with a tweezer to reposition on the fin line and this happens just now

That doesn't look like an upscale.

Assuming the matt has a 1/4" grid, and taking rough measurements therefrom:

• The full fin span (to the trailing tips) is 4.75"
• The semispan is 1.5"
• The tube diameter is therefore 4.75" - 2*1.5" = 1.75"

Since that's all very rough, assuming the body tube is a common size, it's BT-60 (1.65") which is the original kit size.
