Do you wire both of your Altimeters to one switch? I have been wiring up two switches......Didn't realize that you could do this with one? Is there an advantage to just the one switch besides AV space? Thanks for your amazing videos...I have learned a ton!!!!!! :)

Will you share the info for the Ematch Connectors with the Knurled knobs attached to the bulkheads...... My Charge wells have similar ones but are built into the well and are pretty small Thank you !!!! `Glasspack

Thank you for sharing the video ...... I am currently setting up to test my Dual Deployment setup for my "Antares IV" that you may have seen Fly at LDRS41 !!

Great video… thanks for the tips!

For the batteries, look for disposable vape pens, they have single cell lipo batteries of varying sizes, you can wire them in parallel for more capacity and in series for more voltage, these will need balance charge leads

That is the way to do it. Well done. I also use the pill boxes as canisters

Cool! What are the characteristics of the engine? diameter and length

Sir, how much sugar and potassium have been added? Please tell me 😢

What mesh of titanium are you using? I use a pretty coarse mesh and it lasts longer and creates a larger spread kzbin.info4iMBUVd56Tk?si=ZQz2qB5efpEF58Z6

That battery with the built in charger is awesome. I would love to be able to use that but unfortunately, I'm using the EggTimer Apogee controller and it needs a 1S Lipo at 3.7V. I used the Altus Metrum EasyMini a few years ago until I had an ejection failure and it pummeled into the ground and it turned into $80 of tiny bits.

I appreciate the guide. I have zero idea how to even get started into DD. How would you compare DD vs something like the Jolly Logic?

What was the first mix ratio of fuel and sugar? 165 grams you had made?

What's the distance you have between the top of the rotary switch and the surface of the inside of the bay? I was thinking of using one of these for my level 2 certification and was wondering what the minimum distance between the two could be so I don't make a pressure-related mistake

Shit happens

Can you use brown sugar

Professor please how is 98% calcium nitrate made which fireworks are made from Please answer me and do not ignore my words please🙏

Thats a good video. I need to buy some tools like you have to make my motor building life simpler.

Bummer... I had the same thing happen a few months ago

That's Abad day

The 3d printed fin can reminds me of US Water Rockets doing similar things years ago with namely these two links: kzbin.info/www/bejne/aH2cpIh3osqpsMU kzbin.info/www/bejne/ponHg62Ja82mj9k In any case, good work, and that was a really cool flight to see!

Very Nice man

Thanks for the video - I’m almost finished with my level 1 Zephyr and am thinking about what motor to use - do you have any suggestions?

Great video...thank you.

Great video, thanks ❤

What ingredients are required to make the smoke black?

65% is equal to how many grams?

Great experiment.

Very nice

Thanks for sharing 👍

Napthalene is used in some Russian smoke devices that give a really dense black smoke. Not sure how well it would work for a rocket motor but it might be worth trying.

Nice... Bummer you didn't get what you were looking for but good test anyways. I'm working on a "smoke" project as we speak but I'm sure you'll see that on the channel pretty soon. Well, that's optimistic... You'll see it soon if it isn't a complete failure :)

Great video Chuck… look forward to more on this project!

Hi I'm in Australia, cheers Graham

Would b mean nice if you explain how to make them and which was the best, in your opinion. I'm a newbie and trying to learn cheers Graham

And how do you add a Delay mix?

I am actually looking into joining Michigan Team 1. Is there a specific environment, requirements, or traditions in this club I should be aware of?

Thanks for doing this one. Just heard the guy from Mac Performance on The Rocket Show podcast. Looks like it's fully machined.

I don't understand how to add a delay mix.

Hello, thanks for your passion and sorry for my "italian english" I want ask you a question, I'm a biginner and actually try only small candy "rocket" with about 40g (0.09lb) with a wooden stick. I decided to try 3 sample with the same cast, 2 of them on a scale and the last for the flight. Every time the samples on the scale give a good thrust (good for me, about 3.3lb) but the last sample doesn't fly, And the stranger think is the difference in thrust time, 3 to 5 second for the good sample and 20 to 30 second for the flight-sample. I had some good and bad flight with other candy rocket, but for a standardization I decide this "three sample mode". it seems to be a difference in thrust for the rocket direction... Have you some ideas? Thank you very much

can you use the same process, similar recipe, casting method, tools, etc., but rather than limiting it to 29 mm or 38MM, can it be done for 54MM motors as well?

Great Video! is there any alternative to gorilla purple prima glue.

Why the inhibitors for grains are necessary?? Plz reply 😭

Just watched this one. July 20, '24. I replied last week for the first time. If the only thing you added was aluminum, you are going to be short on oxidizer! Decrease sugar proportional amount, then experiment!

Deploy at apogee (tilt over) and use a wider harness

So what was in the pan in the first place?

What ingredients does the remaining fuel have? How is it made?

I need the ingredient link

This is my favorite channel about model rockets. I have a question: should not the outer surface be inhibited? Thanks

We used to use plastic syringes for the kero syrup. Make a stand to hold one syringe upright, with the plunger removed, on the scale, reset scale to zero and with another syringe slowly add the syrup. Get the kind of syringe that has a short nozzle with a cover. LUR-LOK was a brand name, and I'm not sure in the spelling. The second one can be any type. 45 years ago any grain elevator or animal supply would have them. Today, who knows where you can get them. Makes getting the proper amount of syrup into the mix less messy!

I discovered your channel today and watched a number of them. I saw a number of you videos were about adding Aluminum powder to your fuel to increase pressure. While this might work, a safer alternative is iron oxide. If you addressed this in other videos, I am sorry to bring it up. But if memory serves the iron oxide doesn't actually burn, but acts as a catalyst for the sugar KNO reaction. 1-5% is plenty. Please, DO NOT TAKE MY WORD IN PLACE OF DUE DILIGENCE! I recently retired, and have not flown rockets for nearly 50 years. A lot has changed, especially the electronics. I used a mechanical timer to deploy parachutes. OH , iron oxide is used to color cement. Should be readily available at redi-mix company or they'll know where to send you. I live in Wyoming now. Attended U of MI as did my wife. I am planning on getting back into the hobby. Keep up the good work!
