The potassium nitrate needs to be powdered. The granule size should be about the same as table salt.

I go for more of a roundover on my fins, a sharp edge tends to get damaged over time. This is my most recent altimeter bay video. ruclips.net/video/PKDsIvPRJgI/видео.html Good luck with your Big Daddy, it's gonna rock!

@@TheRocketeer that's helpful... I've seen that altimeter bay video before... good model to follow!

The alarm weighs 27 grams without the metal ring that is not used and 36g with a kevlar loop and quick link. Please us the affilate links, it helps support the channel.

@@TheRocketeer No problem, if you mean the Amazon links. Not as “technically” adept as I used to be! I have the FIXIT tool on an Amazon wishlist!

I hope the locator helps!

I’m glad you found the video helpful!

Safety Guidelines for Cooking Propellant Avoid Stove Tops in Kitchens: Cooking propellant on a standard kitchen stove is strongly discouraged. If powdered or liquid fuel comes into contact with a burner, it could ignite and start a fire. Preferred Equipment: Induction Cooktops: These are ideal for their precise heat control and enhanced safety features. Portable Cooktops: For small batches, consider using a portable cooktop in a well-ventilated outdoor area or a garage. Safety Precautions: Maintain a clean workspace free of flammable materials, including overhead items that could catch fire. Always have a fire extinguisher readily accessible. Use a reliable digital thermometer to monitor temperatures accurately. Personal Responsibility: Ultimately, it is the responsibility of the individual preparing propellant to prioritize the safety of themselves, others, and surrounding property.

Thanks for your generous support, I really appreciate it!!

Yes, you can replace the sugar with sorbitol. Do not use corn syrup because it will make a gummy mess. Kno3 65% / Sorbitol 35% is what you want.

This is how I make the fuel. ruclips.net/video/8_GsleHQZGw/видео.html

What do you think about tamped fuel. Potassium nitrate + sugar?

This question was answered here: ruclips.net/video/lXDWVpMD4DA/видео.html&lc=UgzgI02zFclLZ-XaCQ54AaABAg

The core can be 3/8 or 1/2, depending on what you need from the motor. A 3/8 core will allow more fuel, while a 1/2 core will give better lifting power. The number of grains, nozzle diameter, and core diameter determine motor performance. I typically use a 3/8 core for 38mm sugar motors because it gives plenty of lifting power for a Loc IV or similar. I may use a 3/4 core in a 54mm motor to lift a heavy rocket without sending the rocket too high on a smaller field. Excellent question, thanks for posting.

@@TheRocketeer are these numbers figured out through testing, or did you use software to kind of get a starting point? The reason I ask, is because I'm beginning my journey with reloads and making my own grains 🙂 thank you

@@LT72884 I use the same nozzles that Loki uses for most of my 38mm hardware. I use Meteor for my 54mm hardware. My email address is listed on the home page, click the more link at the top. meteor.open-sky.fr/home#/motorDesign Sugar rocket motor design ruclips.net/video/gdD1B3Ki14c/видео.html

@@TheRocketeer thanks. i will try out this software. I am still trying to figure out the equation for core diameter because it seems that core diameter changes with the diameter of the actual grain. IE a 54mm grain has a larger core, But what is that relation? is it a 3:1 relationship IE, the grain diameter is 3 times the size of the core diameter? Thats what relationship i am trying to figure out : )

This nozzle is for a "G" class motor. Then you won't need to make a nozzle! ruclips.net/video/WjYRghviycI/видео.html

For a 29mm motor use a 1/4" core size. A 38mm motor would be 1/2" and 54mm is 5/8 - 3/4".

I have considered using a fast-burning oxidizer with a slow-burning sugar and see what happens. Perchlorates don't play well with sugar fuels. I have blown two cases this year trying to make a red flame propellant. One case was never found even though it was tested in a large open field! Thanks for your comment.

He had an Aerotech H550 in the dark LOC IV. The Red/Blue LOC IV (mine) was using a CTI H123.

Did you notice Mowtown Express clipped the fin off the red rocket next to it? You can see it floating down near pad 5.

There was a lot of anticipation as the rockets were loaded onto the pads. It was a rush when the countdown reached zero!

The race grows larger every year, bring it!

Not him, but if I had to guess, the red one was his since that's the only one we see onboard footage from at the end Well a still from the onboard footage, but same difference lol

As he mentioned in the video description, the red LOC IV is mine. The still is from my onboard video. You can see the whole onboard video here: ruclips.net/video/9ISuwxtRCX4/видео.html I also got the onboard video from the other guy that was on the same launch pad as me. The two rockets collided!!!

Watch pad 5 and you will see a fin flutter to the ground. The Aerotech H550 Super Thunder is one rowdy load!

Welcome to the club! Your first few visits might feel a bit overwhelming with all the activity, but don’t worry-we’re here to help you get started. Launch Schedule: Primary Location: Launches are held at Alkay Airport on the third Saturday of each month, weather permitting. Winter Location: In December, we don’t launch. For winter months, launches take place at our Birch Run site. Check the Team1.org website for updates. Timing: Setup begins at 9:00 AM, and we’re usually ready to launch by 10:30 AM. Flights typically continue until around 4:30-5:00 PM or when we run out of motors. If you have questions about what to bring or need tips, feel free to reach out to me via email at CaptHaywire@gmail.com. I’ll be happy to assist!

I had a great experience at Bong and would love to return someday!

Glad you enjoyed it!

Thanks!

You can skip the washer, but the extreme temperatures will erode concrete. You could use only concrete and skip the divergent, which would allow more material to absorb the heat.

Thanks for your comment!

@@TheRocketeer I'm for sure gonna try this on my own rockets, I was looking for a cheap way to make a nozzle that doesn't burn up immediately and that isn't entirely made of metal. 👍

Even with dual deployment, the top of the airframe tends to accumulate damage over time. Just this past weekend, I watched as my dual-deploy rocket free-fell 20 feet before the shock cord fully stopped it. Thanks for your comment.

Thanks for supporting the channel!

Ammonium perchlorate is available in the US and is often used in fireworks. It may be prohibited in other parts of the world.

My Lipo died after hanging in a tree for a few days. It went dead and that was it.

Using two e-matches may be sufficient, depending on the motor's core size. A dipped e-match burns longer, which is important, and hurls burning aluminum balls into the core of the grain.

Oops, thanks! 9-volt rechargeable battery. 2 pack - amzn.to/4effs5l 4 pack - amzn.to/3MZ2Jrl
