I used to build 6 man commercial hovercraft and have built models. The problem with models and small craft is the available parts are made for aircraft. So the propellers have too large a pitch and are not meant for ducts. I'd suggest using 2 or 3 two bladed mounted onto one motor shaft. And crop the tips so they are wider at the tip.
Also you should not taper the duct after the motor. It should be parallel or even slightly divergent. Tapering is for jet aircraft as they travel much faster.
Could you guys get an EDF type fan to put on instead of the props? It would create a crap load more pressure. Probably not something you can buy off the shelf though.
Looks great! Awesome job you guys, didn’t think it would get so complex but y’all are pressing for greater detail.
I do wonder why you didn't go with multi-blade fans like on commercial personal hovercraft. Surely they would shift more air than a two blade prop? For lift & propulsion.
I definitely agree with you on what you are saying, and it simply comes down to we are using what we already have and reusing stuff that is at our disposal
@@davidjester5085 I get that, but by using the wrong kind of fan you're making a really inefficient machine, adding way more weight and cutting down on battery time. With a fan providing the proper amount of static pressure you could cut way back on the throttle and run this for hours instead of minutes.
@@davidjester5085 understand scrounging parts but cut some hubs down or make adapters so you can run 4 blades on each motor. Block the middle ~1/3 of the duct under the blades for pressure
Fantastic work, guys! 😃
That's a wiring nightmare! Kudos, Dave!!!
Stay safe there with your families! 🖖😊
If you don't make a deeper skirt you're gonna be stuck only being able to traverse extremely flat or level surfaces (watch your first road test to see what happened when you hit that first bit of uneven ground where you grounded it).
A deeper skirt would take up that dip, you would not lose air pressure and you'd keep moving. Watch clips of the military ones to see what I mean lol
Hey Josh, looking good can’t wait to put those wings on this hovercraft lol ❤❤😂😂😂🤘🤘🤘
Static pressure, you need Static pressure, sure the props are large diameter for the model craft you normally build, but the surface area of the blade is microscopic for a craft of that weight especially with people in it. Look at any other fan blade design that actually has to push air: EDF blades, computer fans, vent blowers, axial leaf blowers, airboats, (and I Hate to have to say this but real hovercrafts)
Why bother, it will never "float" high enough, and looks like a hover-craft, should burn nice when the batteries explode though!
I thought you would have a Single Stick in the middle? for forward and throttle and turn!?
if you "enable retraction" youll get rid of the vast majority of stringing on that 3d print.
you need to tilt the inflation props 15 degrees forward.. it helps move the vehicle
if you're adding mylar for the reflection, you should add a base layer of some abrasion resistant material for the skirt, the boat is tough but not rough parking lot tough
Really wanna se the completed one..Great Job Guys
I guess this is the last video. 😢
Please build a giant Aircraft carrier to carry airplanes so you can fly and launch them off of there😍
Consider: For the sake of Air Volume. Expanded Metal mesh as a hood insert would tend to maximize air flow. Mirror Mylar skirt laminations would tend to go well with aluminum foil laminations. Propane Iris afterburners would be a blast.
Again, I must say: You're a genius, David!
Dave should get a raise. Jaja. What an incredible asset to the company. Building a battery bank from scratch requires a lot of research and skill. Great job Dave!
i so hope you guys listen to what i said before and triple power.
I SO agreed with you that they most deffy need MORE powers! Cuz right now they only have I think, I'm not sure, but I think they have 8 motors on their hovercraft right now, so I'm thinking they might need 2 more, total of 10 motors total, cuz their hovercraft have soooo much more weights added into this hovercraft, so 2 more motors should be able to fly them off the ground, even maybe few inches or so, that would be mission accomplished! 😂 But they did great works, especially for Dave, he did soo good works on electronics, and as well as for Josh to manufacture the body work with foams, what do you think of that could add 2 more motors somewhere in their hovercraft? 🤔.
P.S.
I would guard the "manberries" more...
If those props go....
I have a feeling you will need to use reverse thrust to steer from the 2 side thrusters. the one top should be set up for power a rudder is needed but then you do not look like your objective.
Great work so far guys. If you can integrate the yoke pulling and pushing to also control the main blower motors, that would add a nice touch to be able to fine tune / control the main bag inflation while driving. May the force be with you.
You would want independant control over the front and back rotors to level it out depending on who's in it. But, you wouldn't want to control the inflation with a yoke. You pretty much want it on or off with a front to back dial.
I love you guys to much to explain I’ve looked up to you a lot I’ve been watching sence almost the beginning as far back as the cinder block plane. I do have a question. I would love it if you Awnser but if you don’t that’s ok. Last flite fest I got your master p47 I finished it 3 days ago and now we are going to paint it anyway for a silver/aluminum look what paint do you recommend this is my first time painting one of your planes. Thanks keep it up, below is the paint scheme we will do
Please tell me you have some other communication than discord … I’m 14 and for some reason my mom doesn’t approve:(
I love that you're showing us the electronics in more detail - there are so many disciplines you cover to create RC craft - and each could be a channel of their own :)
We would love to cover more but unfortunately it is very difficult to put so much information into a video without making it 4hr long. Thank you for watching!
@@davidjester5085 - I get it :) thanks though - that wiring loom was pure art :)
It's "R/C".
Beautiful construction!! I think the way Normal hovercrafts are designed, with a flat bottom and all the lift air coming from the edge out the bottom of the inflated skirt would take a lot less power. multi rotor lift and hovercraft lift are different. good luck
Yeah, I never liked their "skirt" design. I think they're loosening a lot of efficiency.
This thing better be driving around when I come for the Spring Open House next month! Also I’m curious. You mentioned previously that you’ll be reviewing planes other than yours again. From what manufacturers can we expect these reviews?
slow and steady. Take your time and do it as best you can. Dave is an R&D genius!
Thank you! I just want to clear this up and say I am nothing special. I do what any other person can do if they put their mind to it. Anything is possible if you approach things with the right attitude and mine set.
I think your right about Dave! I love Flite Test
@@davidjester5085 My be not every body. but yes I get stuck on problems some times, Your team is a lot of times is a good thing but you are growing with your job and we noticed! Thank you. I love Flite Test!
If you put controllable louvers on the left and right intake, the blower motors could alternately suck air from the right or left, which might offer some bow control. (same for the back, for a turn in place without extra motors)
Just don't let the smoke out of it!
Refill kits are at a premium.
Hi
I can't wait to see it all done and working.great job lads.
PLEASE MAKE A SMALLER A 10 KIT PLEASE
Do you ever do helicopters?
Could you make a c-17?
First ome
I have three ideas for you to build.
1: General MacArthur's private plane
2: P-80 Shooting Star
3: F-86A-5 Saber
Not ET, "Deep Thought" from Hickheikers guide to the Galax, 42 Stay Mellow Ppl´s
Throttle control should be through the wheel push in move forward, pull back stop reverse through the stick.
The Navy LCAC hovercraft is considered an aircraft. I assume your speeder is light enough. You could theoretically register it as an ultralight. 🤔
3:29 - Does he have to hand-catch the quad carrying the insta360? Landing on its own would probably risk scratching the lenses?
The wiring and electronis development portiponno is my favorite as a 40 year tech / mech on Arcade and Pinball games.
For my last 8 years working full time I was building Multicade 60 in 1 Arcade games using old Arcade game cabinets as well as new out of the box cabinets.
I used new jamma harnesses, led lighted game buttons.
I'm the only person who installed flipper and shake buttons on the side of the cabinet level with the control panel so the digital Pinball game could be played like a real Pinball game insteadofusing the joystick.
There was many other mods I had to do including braiding the wiring harness.
I'm now converting a 25th anniversary Pac Man game that the original power (no over voltage protection built in) supply blew out the mother board with a 60 in 1 Multicade board.
I also installed a lighted mini track ball to play 3 trackball games instead of using the joystick for those games.
The one I'm doing now has no actual coin door so I'm going to have to move the test switch located on the lower right backof the cabinet to the top right back and add a on/off toggle service switch to program the games limiters including number score levels of lives ect..
For me, it's going to be as interesting as your component design process and wiring installation which I'd be tickled pink to be involved with.
You guys are doing a bang up head thimpin' job on that machine.
Don't forget folks, THIS THING FLIES TOO!
This is looking amazing! That's a badass wiring job!
One of the discoveries made in early work was that it's more efficient for the lift fans to actually blow through the skirt and vent into the underside sideways towards the center of the vehicle. It was more stable and efficient, though I don't know how much.
It's enough that if you design the vents just right and have enough airflow, you can actually ditch the skirt entirely as the air effectively forms its own invisible skirt via air pressure.
If you want to add strength to ur styrofoam, cheaply and easily, just latex paint it, put fiberglass window screen material or cloth on the wet paint and immediately paint it again. It will surprise you how much stronger and durable it makes styrofoam. Crashes will be less damaging to wings and fuselage...(poor man’s fiberglass that won’t dissolve the styrofoam)
Be careful not to kill the power while you’re moving. Turn the craft around 180 deg then use thrust to stop.

E.T’s family were in Star Wars,so E.T’s head for the console is quite apt 😂😂
Are you trying to build a scale model of the Star Wars one or something that works well? Too much emphasis here on making it look pretty I think. Copying the Star Wars shape has resulted in too many compromises in fundamental hovercraft design. E.g. larger diameter thrust ducts would give more effective and efficient thrust but not truly be to scale. Or you just put lots of power or a jet engine into the small ducts.
Once again a great video!I just want to give a suggestion to make a Curtiss P-40 aircraft of The Flying Tigers remote control plane if u haven’t
Today on how to waste your time-hovercrafts😂 Bring back flight videos😊
You have such great ideas! However, with your success you have gotten away from what started this channel, encouraging everyone to get out there and try it. Get into the hobby. Now you create things that are pretty much out of reach for everyone. Great channel, great content, just not for me anymore. Although I am unsubscribing I am sure you will do great. Good luck in all you do!
i have a project for you after the Land Speeder.
I need you to design an aircraft that will handle a 400 mph tailwind, ..i need you to build a cheap autonomous drone to fly into a storm and carry a sensor payload,...are you up for the challenge?
Why is one of the lift props at 15:08 upside down? Wait... was that because you couldn't get a left-hand prop for counter-rotating? I hope that shot was an early mock-up and you have the proper prop (er) now.
While it wont look as much like the SW Speeder, if you are going to have differential thrust on the engines, I think you really need "skid steer" style controls rather than "throttle and steering wheel"; it will also give you the most effective "brakes".
Im excited to see this thing floating cant wait
I think I might start designing and building my own at some point. But I have a bit of a different design in mind.
You should look up Aurebesh (the Star Wars common alphabet) and change the words on the console to Aurebesh instead of our own alphabet.
You guys make me sick, you get paid to go outside and play every day!!! LoL I love the content and the fact that you guys are so decent and respectable. You can get your message out without swear words, even when you crash the plane.
Diamondback is on my truck and I can hands down day it’s a savage bed cover! I’m a general contractor and I’ve had all kind of stuff on it including a four wheeler !
You guys have built a lot of cool stuff, but this in totally next level! I can't wait to see it when you finish building!
Love the cmmg shirt
So test flight is now test hover. I subscribed only because of the increadable planes an flying . Sorry not interested in hovercraft . Your channel , your content , I am no longer interested dont need subsribed for me. Good luck with all you do.
Guy's please, please, please!!!!😢😢😢🙇, make an rc giant F-35
At 15:06 it looks like something ain't right with the upper propeller. Is it mounted upside down or something? Is your intent to have the propellers turning opposite directions? If so is one prop cw and the other ccw? I'm pretty sure something is wonky there. You will lose a lot of efficiency if this isn't correct. It's easy to get wrong. Ask me how I know.
e
When mounting the steering wheel leave clearance for the windshield
Can someone explain what the switches on the transponder do, I didn't get it the first 5 times.
Not to be THAT guy but the weight and complexity of the "bag" and blowers is extra weight you don't need. Did you guys research how actual hovercrafts work? The thing that keeps the air in underneath isn't a tube, it's a flexible skirt.
which drive-thru fast food place are you going to first?
What about that new toroid prop design that's supposed to be quieter and provide a little bit more power?
Yeah for the thrust just add more propeller in the jet shaft than you might produce more
That thing is loud! You need headsets for operation without going deaf.
looks a bit like a FLINTSTONE car
How much energy do you do you lose from noise? Better put in a com system.
Nice!!!
Is it me, or does the top propeller look to be upside down? 15:07 shouldn't the logo be visible?
How many Ads can you cram into a video. Ridiculous.
Next you need to build R2-D2 and C3PO
You should solar panels on the nose. To charge the batteries.
Make the v1 flying bomd
hacksmith would love you guys to help them out at some point.
Please cover it with fiberglas when its finished!
It’s looks awesome, coming along nicely!
The big kid in me, is getting really excited about seeing this project finished and working. 😊
It is getting very close! I can't wait to drive this thing around the golf course!
Sandpeople. Just sayin'.
Congrats on the improvements
I was first
Amazing project!
Are you going to finish it or just leave us hanging?
This is looking awesome!
Loose the inflatable boat thing and get a proper bag.
Make a plane that we can buy with a drop shoot
You should make the forward throttle integrated into the yolk so when you push it in it goes forward and when you pull it back it comes to a stop. Separate button for reverser, momentary switch or something.
Super awesome though, can't wait to see the final product.
Really enjoying the progress you are having. Going to be awesome. This Old Man from Washington NC loves you guys. ✈️🧔💝
Dave is The Man! I wonder if he has his own channel
Astounding job on the wiring Dave!
Thank you!
I believe he has earned the title: Doctor Dave 👍
15:06 turn around the upper propeller :/
7:20 Stringing!
STRINGING!
Kill switch?
Well, that is a totally different beast than what you started with, so my prediction about capacity of OK for one 4-legged wookie and fat chance for Bixler is debunked, 👍👍👍. But one thing comes to mind, (I'm missing the flabbergasted headshaking emoji) what ever would you do without Dave? If I recall right you are planning sound system on your car (perhaps go easy on subwoofer), playlist has to have hits from Figrin D"an and the Modal Nodes 😊.
🛹🛹🛹🛹🛹🛹🛹🛹🛹🛹🛹🛹
Totally amazed guys. Dave you are an absolute whiz. Oh for you young guys that means he's really Good at what he does to borrow a British phrase, I'm absolutely gobsmacked
You could add some mirrored armor panels, like in Spaceballs. From a distance, it might make a cool effect. I suppose, if the controls were made to be fly by wire, then you could easily control everything by R/C, too. Have a computer actually fly it, but interpret input from the controls or the transmitter.
Looks awesome guys!!!! Can't wait till it's done!!! Josh, on your quad or tricopter design could you put in a self leveling camera mechanism? or even one that has head tracking.
