Propeller Backpack Part 1

[@babumohan4549]

samm shepherd,the another name of innovative invention.i hope that you fly high around us.rest in peace,brother.

[@foobar201]

Attach a wrist band to the transmitter or something, this way if you drop it you're stuck with the propeller at full throttle.

[@GavinRemme]

May I recommend that you put the throttle control on the spring loaded side of the transmitter? That way of you drop it or something it will return to zero throttle :)

[@sendark001]

There I was thinking you were just a really talented engineer, only to find you're also a total nutter. 👌💪👍💯

[@SuperFrodo95]

He's no Colin Furze.

[@youtubeguy3544]

LazerSausage I like his vids more than Colin

[@youtubeguy3544]

LazerSausage He needs a safety tie

[@Designandrew]

3:11 can hear your heat beat.. also you should use two EDF's mounted above your shoulders.

[@SingleMaltZombie]

Aw... That beautiful snow... I wish we had that here in Germany, at least for Christmas.

[@grigol101]

Well now I know why you came to Moscow and Stalingrad

[@cup_and_cone]

If you drop the transmitter you're basically SOL. I think it would be slightly safer ditching the radio system altogether and using a wired servo tester plugged direct to the ESC as the throttle control in your hand (have to solder extension wires).

[@SammSheperd]

I was gonna TIG weld an aluminum frame and use a wired trigger throttle but the snow made me rapid prototype a bit faster. The main power plug is within reach but a better kill switch would be nice

[@thesherm44]

Honestly, what you should do is use your trainer switch as a dead man's switch. When you drop the trainer switch, throttle goes to idle. This way if you drop the transmitter, the throttle goes to zero.

[@Designandrew]

meh you could just fall backwards to stall the motor if you lost the tx

[@MrJob91]

and eat some free spare meat!

[@jacobrachwal7625]

Very smart Idea!

[@GavinRemme]

Jesus that motor is GIANT! And where in Cali? I'm from Sacramento.

[@SammSheperd]

Santa Cruz

[@Invisiblejihadi]

Awesome video! You should definitely see how that performs on snow off the road, and see how fast you can go

[@chickennn7830]

So it's a blender on your back

[@mreid08]

that motor and prop on 12s makes 36 pounds thrust, I know this because a friend has a plane with this setup and the motor is under propped, but this looks like a blast except if you wipe out with a lawnmower mounted to you back

[@furonwarrior]

Use a three bladed prop. They're more balanced when handling variable yaw axis such as you moving side-to-side.

[@DrZoidbergism]

if you loose the remote while in flull throttle you are basically screwed do you have a safety switch you can reach without getting your hands dangerously near the spinning blade of dismemberment? I hope so.

[@MindCrime550]

Since this is thrust vs friction (skis and air resistance) aren't you going to keep gaining speed until those are matched? I mean if you tuck and keep it on full aren't you gonna be doing 60mph eventually?

[@twingall1417]

Awesome! How much total time at full throttle will the battery give you?

[@Heimbasteln]

Oh man, we dont have any snow right now. And we wanted to go skiing after christmas but if its too warm and there is no snow... You dont know how much I envy you right now (Germany)

[@zieperegrine5237]

Reviews+Tutorials dutch here, WHERE HAS THE SNOW GONE!

[@janettesheperd2786]

This would be perfect in a Warren Miller movie!

[@ramradhakrishnan9382]

Awesome, Samm! I hope you are taking adequate safety precautions. Remember, some of us oldies live vicariously through watching your videos :) BTW, Turn on GPS logging on your smartphone and see what top speed you're getting. Also, if you hunker down on the skis and allow more "open" air in front of the prop, you may get higher speed/longer runs/cooler hardware. And... you do not need a transmitter, just a servo tester should be enough for speed control, right?

[@curbyweaver4606]

Samm, use an impeller blower like you did with your RC airplane for your backpack. It could be used in population dense areas without being a hazard. Mount one on each end of the motor/both sides of the backpack.

[@patrickmutuku9579]

Hey, Nice video there. How much thrust was the set up generating?

[@AshutoshSingh-to9vx]

4:23 what a beautiful landscape

[@cmdrpepelluce5375]

It would be cool to make some kind of simple controller you can comfortably bring in one hand and focus on skiing

[@tooniis1403]

Didn't you think of the possibility of the transmitter falling off your hand??! you should use a wrist strap or something next time.

[@Aegrim]

You're crazy that's an amazing use of the equipment.

[@ChrisMisMYhandle]

cool video. looks like there is plenty of power there!

[@Lee_Lee1776]

Did you get this from ACME? Wile E Coyote had one like this.

[@JamesFenechClimbing]

This is awesome, thanks for the upload! How long does the motor you used take to drain that particular battery?

DIY powered paraglider next?

[@SammSheperd]

Probably coming soon to rctestflight. Daniel has been working on one

[@aerialproductions5481]

I've seen this done before with 4 EDF's, was extremely fast!

[@shutdahellup69420]

The drag affects tremendously.... what's the top speed btw? ;)

[@arnaudberard64]

Cell checker or lipo testers on the market are limited to 8s batteries and I want a way to adapt them or to make one that can test 13 s batteries

[@SammSheperd]

Oh they only make balance leads up to 6s. My 10s is split into two 5s balance plugs and I charge it through those as if it were two 5s batteries one at a time.

[@unknownchannel2171]

can you use this as paramotor

[@Zachsnotboard]

same thing with a longboard ?

[@garyowen3829]

maybe where the lanyard on the transmitter cuz if you drop that you're screwed

[@SammSheperd]

slightly annoying, not screwed.

[@garyowen3829]

Samm Sheperd I suppose you do have a backup in case of loss of control

[@Ggddsdddhhhhy6fv]

When did you move to the pnw?

[@SammSheperd]

+Da S been living up here for 4.5 years. Grew up in Cali and visit sometimes

[@TomBerghuis]

How long do you get until batteries need recharging?

[@roehle9962]

Gotta go to school like dat... I even got a turbojet engine... now I just have to learn how to ski :D

[@Jhinsydney]

just aim and squeezze ;)

[@jhendkap.2340]

goodness that looks so fun. what laws are you breaking?

[@colinmcloughlin7475]

Your should make a video on how to waterproof your quad during the winter months.

[@SammSheperd]

I have all the footage I need for that it's on my to-do list!

[@SammSheperd]

It's been out btw in case you didn't see it

[@colinmcloughlin7475]

Samm Sheperd no I've watched it multiple times, great vid!

[@the_real_foamidable]

You just invented a new sport! Good thing you wear a helmed though. Just thought about what might happen if the back of your head comes in contact with the prop.

[@motkoloko]

So what is the setup?

[@whatnextjoe]

Samm you are very talented, The video is great. Thanks for sharing

[@Zorgen2]

test the propeller on ice with skates and GPS to se KMH or MPH

[@xabibilboful]

you should try yo build a sled powered with a propeller or something, like a swamp boat. Awesome video as always!

[@SammSheperd]

See my newer video I did this

[@arnaudberard64]

Hello Sam , I'm on a electric paraglider project and we will make a screen which says you the battery left and advertises you when you're low voltage .Do you know how to control the battery voltage on a 13 s ?

[@SammSheperd]

For an electric paraglider you'll need about 3x the power as my setup. I've seen a 150cc equivalent motor used. I'm not sure what your question is though.

[@Floh545]

I would use it for my paraglider ! I'm sure the power could be enought for get some feet high ;)

[@dkhallal]

Floh Alishanmao did that, it was very cool.

[@PrestigePotato]

I'd be scared to accidentally fall to my knees and have it lop my legs off

[@electroman1556]

how many km from the snow area to your home?

[@SammSheperd]

+ElecTroMan DIY AMPLIFIER I went about 2km from home to get out of town

[@basslinedrc3dfpv827]

that looks so fun

[@thelennipede9382]

Hey, what fps goggles would you recommend? I'm looking at the: Attitude v3 Dominator v3 Skyzone sk03 Which one should i get? Thanks! Your videos have inspired me to make my own aircraft using this method and i am prototyping a racing wing :D

[@SammSheperd]

+The Lennipede those are all good goggles. I have only used the dominator v3s and I like them a lot

[@TheMertonator]

do it with rolerblades

[@kimchikoalaa714]

Xoar stuff is pretty efficient

[@ConnorWeller]

Which college do you go to?

[@TheAngryAstronomer]

Instead of radio gear why dont you use a servo extention lead with a servo tester on the end to make a one handed throttle :)

[@28th_St_Air]

i think this is super cool. i think i speak for others when i say that we like you and want to see more Samm with all flesh attached in future videos. please put a cowling over the whirling blades of doom. :)

[@madswarming-hansen9044]

You should try making a rudder.

[@SammSheperd]

+mads warming-hansen or you know, turn with the skis

[@madswarming-hansen9044]

Samm Sheperd aaahh, good idea😉 Love your vids!!!!

[@BrettWae]

should do it on on a frozen lake with ice skates. Much less friction.

[@markusk.488]

how much Watts have the big Motor

[@SammSheperd]

several

[@JacobDavidCCunningham]

Dude you are brave haha. 3mo late comment but. That big propeller in the back, I realize for example powered parasail people wear a similar setup but damn... I'd be scared, biggest propeller I ever worked with was a 12" prop haha, and that seemed scary to me. edit: ahh 1:57 it's not gigantic but still, I've been hit by a spinning propeller a few times. I'd feel better if it had a guard. 4:52 slope soaring

[@hi3267]

where do you live in the Pacific Northwest I live in Washington!

[@SammSheperd]

Walla Walla. Part 2 coming soon :)

[@hi3267]

Samm Sheperd awesome I actually have been thinking about building my own racing quad and I watched one of your videos and you are very detailed and intuitive with your instructions! is it worth it?

[@SammSheperd]

The ultimate goal is to get to a point where you can go to a field, fly a few packs, and go home without breaking anything, but It is a lot of work and learning and money to get there :) Totally worth it if you're motivated to get there.

[@hi3267]

Samm Sheperd I got a kit and a transmitter for about 144 bucks I have some soldering skill so I don't know what I'm in for lol

[@sp00nix]

What if you pizza when your supposed to french fry?

[@hanoverview]

LOVE IT ! MAKE IT BIGGER !

[@Y13A]

WOW that looks fun

[@Designandrew]

Hey what is the name of that other youtuber who is like this guy, but has a green logo and it's like "rc something" he makes like lots of vidoes in snow with ground effect planes, and quadcopters with bright lights... i'm subbed to him but havent seen any vids recently

[@wendtb]

Designandrew rctestflight?

[@Designandrew]

That's it! He's into paragliding now check out his latest vid it's insane!

[@osimmac]

It would be really cool if you used this powered backpack with a paraglider...

[@Rusty_39]

You should try that with a weed wacker engine! Nice video

[@SammSheperd]

Don't think you'll find a weedwacker anywhere near this powerful.

[@jackpb_5253]

Imagine doing that down a ski slope

[@rytold8471]

Put your patrons in the descriptions! :)

[@SammSheperd]

oh yea I forgot thanks!

[@rytold8471]

;)

[@maxjones1414]

u can steer while on skiis so dropping the tranitter would only be an annoying occurrence

[@ShafaqIftikhar-pw9ld]

Lol love it like a jet ski on ICE!!!!!

[@gregroberts7394]

USE IT WITH A SKIMBOARD

[@SammSheperd]

As an avid skimboarder, I thought about it lol but I also think I would die

[@gregroberts7394]

Yea, the moment you hit a dry patch or a shell your going flying with revved up prop on your back

[@jacobedwards9706]

Samm Sheperd also how would you stand on a skimboard or snowboard for that matter. It would probably be really awkward right?

[@EliasT]

YES THANK YOU FOR THE FULL VIDEO!!!

[@computhenics]

You could attach that propeller to your helmet like Doraemon. LOL. BTW it was nice.

[@jacobrachwal7625]

What I have always wanted to do Is put two Big Ass EDF's on the back of my skis (Like 120mm)Put them on 12 or 14 cells of power and violla.

[@Maxum97SeaDoo91]

That's pretty trick there....Thumb's Up !

[@loichoendervangers6014]

you're killing your skies

[@SammSheperd]

I mean they're from goodwill I don't really care

[@teunje]

That's sick!

[@TheStickyBusiness]

This reminds me of the hobbiking edf office chair video

[@SammSheperd]

In part two you can see at the end I show my new batteries. Matt from that video gave me the batteries used in that video for my project.

[@AdamDemas]

HOLY CRAP that was awesome!

[@Jhinsydney]

That is awesome !

[@ssplintergirl]

Make a flying wing with it.

[@devilsoffspring5519]

Dude, with a REALLY hefty motor and bigger prop, you can ski uphill! Let's see those gold-medal Olympic wusses do that! :) hehehe Just a little tip, not to be a nag, but you *really* should have a protective shroud around that prop. A neck strap for the transmitter ain't a half bad idea either. If you can stand the racket, a two-stroke aero engine is incredibly lightweight and produces lots of power. Even a good-size chainsaw engine is very light--and powerful. Have fun!

[@ashaysave4414]

awesome 🙋

[@BlackPixxelDE]

You better lose your radio while doing a full throttle run :D

[@PrjctMinecraftiaFan]

Holy shit that is so cool!

[@josuehdz0]

Dope

[@carleewalker1942]

Josue Hernandez you're dope :)

[@kaumohlamonyane272]

"Sometimes I question your Sanity"😏

[@grantwarfield4905]

Before I finished the video I put a moter on a slide to see if it can push up and hill it made up with blue smoke. Note to self 1000 kv moters are powerful but not that powerful.

[@FishingWithLogan1919]

imagine have 8 of those motors

[@kokeskokeskokes]

Can I ask what is your propeller diameter, Samm? I thought this may be a neat way to test a propeller out, but the propeller I am working on only spans 18 inches (3D model, please turn your speakers down kzbin.info/www/bejne/in6reWqApcZmma8). That motor is way out of my budget, but I will find workaround, I am sure. Arduino and lawnmower most likely. A personal ski lift...

[@thenhbushman]

I would have made a cage - wouldn't want to make contact with the spinning prop in a accident.

[@SammSheperd]

Totally agree. I did do a lot of "what if" extreme flexing to see in what ways I might interfere with the prop arc. It was actually really hard to reach it. Of course anything that can happen will happen especially in a crash. I made my own risk assessment for to do what was filmed. My new frame has a cage, I'm editing that video right now.

[@youngpadawan7910]

Make more videos!

[@locouk]

Great idea lol.. 👍😎

[@bigDwithme1]

2 big turbines!!!!

[@SammSheperd]

Well that sounds cool and expensive

[@peterbuckles2711]

Do you know how to ski not being rude just wondering

[@SammSheperd]

I don't ski often, thus why I don't own my own set of high quality skis. But I am an avid down hill skier. I can snowboard too but decided I like skiing better even though I do every other board sport in existence.

[@jasperb9025]

try water skeeing

[@maxjones1414]

cool video though. good idea.

[@essentials1016]

awesome

[@jamesomega]

Bicycle!

[@Authoity4576]

thats soooo cool omg

[@themerrigans2734]

perfect.
