My dad is a balloon pilot and builds hot air and gas balloons. We’ve been building tissue paper and rc balloons as long as I can remember. I am going to show him this video over the holidays!
As teenagers in the California Central Valley, we used to set off hot air balloons using dry cleaning garment bags with birthday candles taped to straws that kept the bottom of the bag open. The candles were the kind that can't be blown out. From our experience in the non-windy Central Valley summers, your RC controlled hot air balloon will only work in a windless atmosphere.
Exactly the same in the winter in Erie, Pennsylvania in the late 1960s. Being risk takers, we launched them only a couple of miles from the Erie airport control tower. Only a few were recovered. Most ended up in tall trees in the woods and stayed there for years.
Same in Southern California, except we used regular birthday candles. We taped the top where the coat hanger stuck out so the hot air didn’t escape….✌️
We did the same in California when riding motorcycles in the dunes. Dry cleaning bags. Two sticks of bamboo and a full set of birthday candles. And we would launch them in top of a dune watching them float over the desert
I did the same in Ocotillo Wells using a flare and a homemade balloon. it caught on fire about 1 minute in flight and almost landed on our trucks with gas cans in the back. We always spill race gas when filling our dirtbikes so that would have been bad.
My dad is a hot air balloon pilot so I have several years experience with being ground crew for a hot air balloon, so I don't have much (any) experience with the rc kind, but I can tell you what we do with the big balloons. The line connected to the top of the balloon (the crown line) is normally only used while inflating/initially heating the balloon to control the initial ascent from the ground. It can also be used to keep the envelope from moving erratically if you want to stay inflated with some wind present. The 3 lines you have connected to the basket are for tethering (we usually connect them at the point where the envelope connects to the basket at the top of the tower), and they are the minimum need to fully constrain the balloon over a single spot, but you really only need one to keep it from flying away from you if you don't care that it can move. We usually tether with just 2 lines. The internal line (often called the redline bc it's usually red, or the top line) connected to the vent (called a parachute top) is either used while deflating the balloon, or to let out some hot air to cool the temperature down to descend faster, or reduce rate of ascent. The parachute top is initially held in usually with Velcro to keep it in during inflation, but you can pull it before you deflate the balloon because the buoyant force of the hot air will keep it sealed. Hope this helps, I'm happy to answer any questions about ballooning!
I've always wondered how flight planning works... Like you just look at all the weather information available to you and send it? Just land in some random farmers field and call the truck?
@@randymarsh8936 lol yup you pretty much nailed it. Pick a spot that will give you plenty of opportunity to land and just go for it. The winds often allow for some steering as they'll be at different headings at different altitudes. There is absolutely skill in being able to steer the balloon but if the wind ain't blowing there you ain't going there.
Used to make hot air baloons using dry cleaning clear plastic bags. Started with candles for heat, then graduated to Sterno until one windy night all the sterno fell onto a neighbor's roof. We boosted one of our little brothers onto the roof and he stomped out the fire. Always wondered why none of the home's occupants came out to find out what that noise was! That was the end to our hot air balloon experiments.
Just imagine doing that at Christmas and the kids get excited about Santa coming down the chimney. Funnier still would be if they didn't have a chimney.
Hi. Pilot here. The top line is the crown. It's for use on the ground. The parachute top is used to go down or to dump the air at landing. The teather lines are for anchoring the balloon or to drop to ground crew to handle on landing. Lift is determined by a pyrometer at the top. Higher temperatures are bad for the coating. Keep it under the rated temperature and measure the lift there. Lift relates to the area over the equator of the envelope.
The Cool thing about Hot Air Balloon Piloting is the Steering . I got to pilot one with the actual Pilot as My Copilot and to steer You Spit over the side and see where the lower winds are moving in the direction You are wanting to Go and then lowering the balloon to that level and blowing over the way you want to steer then raising up to straiten out or turn the other way ! So you need to get an RC Pilot that spits for the Balloon now !
I've been ballooning for 10 years now and was delighted to see you messing around with LTA aviation! One thing I was a little concerned about though, your envelope (probably nylon) is considered over-temp above 250f and quickly degrades the fabric, for polyester envelopes it's 300f. Seeing as this isn't carrying passengers it's not like there is much of a consequence here, but just something to be aware of if you want the envelope to last, well I guess forever since it will hardly be carrying a payload.
Tampons make excellent wicks for little hot air balloons. Wrap most of it in foil like a bag. I stopped doing it after a police car hit one that struggled to gain altitude and drifted down the main road through town. S. S. Light days. That was one of my ex's favorite stories to tell. It was going out so they didn't stop and it didn't flare-up. When I was a kid, a Korean vet made paper lanterns that you light the whole thing and it goes as an ember up into the sky.
Balloons were my first aviation love. When I was younger I used to be OBSESSED with balloons. Anything from helium party balloons to hot air balloons. When people would ask me what I liked, I would say “anything that flies”. Of course as I’ve aged fighter jets have become my forefront aviation interest. But, to see my favorite RUclips channel deal with hot air balloons is special! (It’s Peter’s fault I’m flying RC planes too)
@@TheMalformedViperfish since the dawn of our species we’ve looked to the birds and wondered what it might be like to soar through the wild blue yonder. Through the years our technology improved and allowed us to finally find out. In a few hours, I myself will be flying in a passenger jet, airborne as our ancestors could only dream of. I count myself lucky to be alive in a world where flight is possible!
A tall, very thin stainless steel type of shroud/tube with holes around the flame would help keep the flame consistent and also help draw more air into the shroud/flame to be directed into the balloon.
In balloons there is kind of a delay effect, when you burn you need to be aware that if you burn until it moves, you overdo it.. short bursts and observing the movement is how balloon pilots do it at first until they develop a feel for their volume
You are so adventurous and you love to experiment through trial and error and you learn fro your failure ... so fun to watch ... thank you ...❤❤❤🎉🎉🎉😊😊😊 ...
Get a plastic bag from the cleaners, Scotch tape top hole, make a cross of balsam wood and use 2 birthday candles cut in half to make 4. Use on still night only!
I've been playing with hot air balloons since I was a kid (68) and still do. Unfortunately I live in Arizona so......... when it rains really really well then time to fly. What I want to try is those blow up santa clause yard thingies. Weight it just enough to keep santa upright and santa and maybe his reindeer would be flying!!!!!
@@JosephHarnerYeah I was wondering whether an induction by itself would be able to sufficiently produce so much thermal energy for the Ballon to lift
I was one of the n'er-do-wells that got the 1970s UFO sightings really going with cleaning bag balloons, with rolled cotton soaked in wax for heat. My mother was not impressed.
lol “this is terrible, I don’t know who thought this was a good idea, to light these off and let them go.” -Peter @ 2:35 lmao they were ancient Chinese people
It's a great idea to combine the rigid airship + hot air balloon idea. I've wondered in the past if a electric heat controlled (through heat elements) compared to gas powered airship can work. Hopefully you have better ideas for your next airship/hot air ideas
I did make models of hot air balloons myself and actually I found out that you can make one just out of black plastic trash bags and it will lift itself pretty easy by the heat of the sun. So technically you don't even need a heater. But the balloon with fire just looks cooler (or should I've said hotter?) :) There is a very old video of one of mines at my "channel" btw. That one was made of paper and used some solvent as a fuel.
Could the heat gun provide enough hot sit to lift anything? Fingers DC version using batteries to power? If works build light framework to hold heating element, batteries and rc controls?
I actually made one of these eight years ago with a mini butane torch and it worked great. It went so high I lost it could not even see it, but this one’s pretty cool and way way bigger😊
The Canadians proved, in 1998, that machine guns don't easily take weather balloons down. (They used well over 1000 rounds) Does that mean we had to use the most expensive missile? No
@PeterSirpol what if you just make a + frame where it slides the weights up and down and left and right where it will tilt the balloon forward and sideways to steer it?
I've made something similar to this before by hanging a stripped-down tiny hovercraft, which I made from the Flite Test plans, using only rear motors plugged in, from a neutrally buoyant helium balloon or two. When the stick is pushed forward, it causes the entire contraption to roll, giving the hovercraft gondola a slight upward tilt and causing the entire setup to go forward and up. Turning the hovercraft rotates the balloon or balloons, resulting in the entire setup turning the next time you throttle up. This setup works best indoors, where you won't risk losing your toy to an updraft and it getting stuck in a tree ;-) A broken micro drone can also work with just a single party balloon. In fact, this video has inspired me, and I think I'll build an RC blimp using tiny whoop parts this weekend!
I'm 75 and 'back in the day' I SUCCESSFULLY did this using a kerosine fuel-soaked Tampon wrapped in a criss-cross of 30-gauge wire for support, suspended from a thin "X" of wire side to side from a tissue fabric geodesic baloon made of thin balsa strips. Robust, lightweight, controllable.
So... what about using solid state heaters instead of fire? And I've seen stuff about using a smaller balloon filled with steam. Maybe have a two stage design with a small inner balloon with steam, and then an outer balloon with hot air?
Make an oblique adjustable angle flying wing! It would be a really neat video and a great demo of a stabilizing flight controller! TBH, I commented this on the Flite Test Channel also.
Would there be enough power density and discharge rate in a LiPo to produce the required hot-air, without exploding the battery? Could you make one capable of lifting an onboard computer capable of receiving weather data and GPS to allow it to steer by rising and sinking to the altitude with the desired wind direction?
This formula works for boats and airships: max theoretical cargo capacity = density of surrounding fluid × submerged volume - ship mass (which is anything that isn't cargo, including the mass of the gas inside the submerged volume). For air, the density is about 1 kg/m³. For water, its about 1000
The home-made one was close to working better, but I'd suspect the balloon part would need to be twice as big. Compare to the one that was purchased with the basket and all that, in terms of payload vs. lift.
The sky lanterns are absolutely not a fire hazard unless you launch them in adverse weather conditions. Calm skies at night will allow the balloon to ascend several thousand feet up, and will continue to climb until the fuel runs out and the fire dies. Then you have several thousand feet of slow descent for the fuel element to cool completely down before it lands. It presents far less of a fire hazard than a controlled campfire by a conscientious camper.
An integrated heat-pipe that absorbs some of the heat from the flame and transfers it to a jacket/heatsink around the fuel tank would keep the tank from freezing. Added weight, but more consistent fuel to heat output.
I think you’re loosing your heat before it gets to the envelope. Hot air balloons have a small wind guard on one side between the envelope and the gondola. I think adding this would help cut the wind down between the burner and the envelope, allowing most of the hot air to go into the envelope. Happy flying from Dayton, Ohio.
Have you ever heard of Solomon Andrews and his Aereon? He was able to fly against the wind without a motor in 1863. In 1865, he flew from New Jersey, over New York city and landed on Manhattan Island for a few days to avoid a storm. He then flew back again. A post-war recession bankrupted him and he never flew again.
I love your crazy projects. Was thinking with the first couple of attempts, if a flame burned through your string tether that flaming balloon would have been away! 😮. Flexible wire at the last metre would be advisable. 😊
I had one of these with 3 propane tanks that was slightly larger, Harbor Freight sells a brass adapter that allows you to refill those smaller bottles from a regular BBQ propane tank much cheaper. I sold mine because there were never any days calm enough to fly it!
Hey Peter! Not sure if you'll see this but recently I saw a video on oblique wings and I was wondering if you would be interested in building a scaled down design of the AD-1 to try it out.
Thats a cool balloon Peter i like that last one you had a lot of weight in that basket now you can try building a little biger size balloon. Have a great chrismas Peter.
These units could be adapted for surveillance use. The IR signatures would be huge, so not a good idea for military use. @2:10 they get an unintended Ziltch. A Ziltch is when burning plastic makes a zipping sound as it falls dowmward. Stoners are known to purposely burn these to enjoy the strange sounds they make.
Peter has a hot air balloon along 10 bananas and 27 eggplants. Calculate the necessary force required to lift the hot air balloon by itself and then with the bananas plus the eggplants. Assume the balloon weighs 30 lbs, each banana weighs 1 lb, and each eggplant weighs 2.5 pounds. Neglect air resistance and use 32 ft/s^2 as the gravitational constant.
Something ive been wanting to do for a long while...but intelligently Peter stripol- Let me just throw stuff together quick. Lol, cool video. I have a calculator for lift and it takes into account enviromental conditions
Yea, I had the same thought. Heating element/ like the hot air gun used to inflate the balloons in the video, would require a lot of power, batteries and weight, but it would be cool to see it.
On RC helium balloons, they commonly used a multiple sized(weights) hex nuts on a string underneath to act as a counter weight, and VERY easy to fine tune as well!!! Very cool, very different!

I think that a small vertical propeller could be useful here, if you made it neutrally buoyant, it could push it up or down with very little energy

You should do an electric hot air balloon using an induction heater.
use a black dust bin liner and let the sun heat the balloon and the air inside, it actually works.
Too low energy density. Electric flight is all about efficiency. If you just want heat, as in a hot air balloon, you really can't beat combustion.
@@JosephHarnerYeah I was wondering whether an induction by itself would be able to sufficiently produce so much thermal energy for the Ballon to lift

That was about as exciting as a hot air balloon.
You have to remember, the hotter the air, the more lift you get. Even in the same volume of space.

Yup. China sent a couple of them over us with GoPro cameras. Thankfully, General Milli-Vanili spent a $2 million to shoot one down.

When you use the gondola as fuel it solves the issue of not having enough fuel and having too much weight
Lit unmanned compressed gas bottles in the sky. Couldn't see any massive liability attached to something that reckless 😂
soooo .... you're going for that Hindenburg experience? 🤣
Using a gas lamp mantle might be interesting, so there is less open flame.

I love your content, brother. Would love if you create videos, more often!
Finally, some schmuck does an RC Hot Air Balloon! Been waiting for one of these.
nice video man, we anticipate an aircraft project soon
These units could be adapted for surveillance use. The IR signatures would be huge, so not a good idea for military use. @2:10 they get an unintended Ziltch. A Ziltch is when burning plastic makes a zipping sound as it falls dowmward. Stoners are known to purposely burn these to enjoy the strange sounds they make.
where did you get the rc hot air balloon evolope from (the big blue one)
This rc baloon is legit - no strings attached.
Man this thing makes the hindenburgg look safe 😮 but it's still cool keep up the great work Peter 👍
MERRY CHRISTMAS PETER
Now I really want a flying hot air balloon eggplant/banana bomber.
Could you use the exhaust from a car to preheat the air to get liftoff and then once airborne use a fuel device?
I imagine 2:08 is just what it was like when the Japanese were developing the Fu-Go balloon during WWII
Where did you purchase the mini hot air balloon with the gondola?
the cartel lost a good smuggler there 😂😂😂
Hot air blimp yes please!!! 🙌
Peter has a hot air balloon along 10 bananas and 27 eggplants. Calculate the necessary force required to lift the hot air balloon by itself and then with the bananas plus the eggplants. Assume the balloon weighs 30 lbs, each banana weighs 1 lb, and each eggplant weighs 2.5 pounds. Neglect air resistance and use 32 ft/s^2 as the gravitational constant.
Something ive been wanting to do for a long while...but intelligently
Peter stripol- Let me just throw stuff together quick.
Lol, cool video.
I have a calculator for lift and it takes into account enviromental conditions
Man, you always do the things I can only think of, thats awesome!
Always love the variety of your videos! Looking forward to more work on the lobster boat!
Wonder if an E-hot air balloon is possible by lining a balloon with resistive wire on the inside/some other heating element
Yea, I had the same thought. Heating element/ like the hot air gun used to inflate the balloons in the video, would require a lot of power, batteries and weight, but it would be cool to see it.
Solar balloons made of black material would nearly eliminate the fire hazard, but would probably provide less lift per volume of air.
If you can get them to land and auto-refuel, this could be a pathway to swarm-based air defense.
I know you're joking 🎈
Dude you need like a stove pipe to shield the flame and get the hot air in the envelope. Nice bog though 👍👍
"Gramps, how did the Great Fire of 2024 start?"
"Well, sonny, there was this guy called 'Peter Sripol...'"
On RC helium balloons, they commonly used a multiple sized(weights) hex nuts on a string underneath to act as a counter weight, and VERY easy to fine tune as well!!! Very cool, very different!
