EMG-6 Powered Flight Test (Predator 37 sustainer motor)

[@SloanZurnToto]

Neat aircraft. Dump the music, very annoying.

[@OutbackAl]

Yeah, the 1st 8Mins or so of the music makes me want to hit mute.Nice flying machine tho.

[@williamlambdin9817]

I've emailed you guys personally, but wanted to publicly say how much I appreciate the frequent updates on your blog and the great videos. The degree to which you are reporting the progress (and or setbacks) is uncommon and praiseworthy. My flying buddy and I are watching your project with great interest as we have been talking for some time now about building and flying "goat" type gliders but wanted self-launch capabilities. We look forward to your experiments with that phase of testing. Thanks and good luck on a well designed and carefully implemented aircraft.

[@johnhilliard767]

Interesting experimental,however for me the music spoils the video.I wanted to hear the electric motor and wind noise etc.

[@OldMtnGeezer]

My 2 cent's worth: The music issue has been adequately addressed here, so I won't beat that dead horse further - other than to respectfully ask, why is it seemingly deemed downright mandatory for generic canned music beds to be added to 99% of otherwise good KZbin videos in the first place? Most add little & detract much. On the positive side, as an RC pilot who has seen the electric propulsion revolution explode in a relatively few years, I commend this application & wish you continued success in the development of this fascinating project.

[@v.e.7236]

Flying is usually a "peaceful" experience for me, but as others have mentioned, that music is a total buzz-kill! That being said, I like the ultralight and really dig the electric "sustainer" motor. Any further developments?

[@qwicksilver2]

That's a lot of drag having that opening behind you

[@loftsatsympaticodotc]

Great flight video angles and view points. Thank you. (But please keep down the music volume and I'd prefer None - when you are talking. This helped me become a real enthusiast for electric, greener and non polluting, (and quieter) flying !

[@drahomirfidel946]

Nice

[@dorightal4965]

Coal powered flight. That or nuclear.

[@AKNigel]

I know the ESC problem is taken care of by now. In RC planes, I usually mount the ESC externally so it gets good airflow.

[@blancolirio]

Very Stable! An ESC or battery fire would be terrifying...maybe a parachute? Keep us posted!

[@RainbowAviation]

Stable, absolutely. Fire, ahhhh, yeah, terrifying. In my 8000+ hours of flying in different aircraft I've had 3 fires in-flight. And you're right it's terrifying . We put a lot of thought into the whole possibility of a fire from either the motor, controller, or batteries. Keep in mind that the predator 37 installation was simply a test for testing the viability of the model aircraft motor and the amount of power necessary to sustain flight. There was never any intention for this to be a single engine aircraft with the small of the motor. If the tests have been better than what we expected we would have configured the aircraft in a twin engine configuration using this motor combination.

[@billcallahan9303]

Great video but when you have vocals in the audio turn it down so we can hear what you're saying. Other than that, fantastic video! Best of luck! William Catalina "Drifter Flying" on KZbin. When will it be ready & can it be bought without motor?

[@EonRanch]

Hello Brian, the plane is looking great! My Father ( Ben Phillips) and I are big fans of everything you do, cheers :-)

[@ovalwingnut]

Simply MAGICAL + AWESOME + TALENT + CREATIVITY all rolled into one.👍😁 Go flyboy GO! ❤

[@jameslinegar9029]

Can the (noise) music, I'd prefer to hear only the sound of the flight and the pilot.

[@RainbowAviation]

Still hunting for the original video so I can change it

[@Pro5.0]

please for the love of god don't add any music on future videos, this would be solid gold if it werent for the music

[@Pro5.0]

reguardless awesome plane!!

[@tobedetermined3619]

Well done, Adventure Aircraft! I appreciate the frequent updates to the progress site and videos like this. I'm extremely excited for when two-person flights take place. Best of luck!

[@gilesengineer]

I'm afraid the music makes an otherwise very interesting video completely unwatchable. However, good luck.

[@flytoday]

Not a fan of the music. You thought about using a heatsink instead of the fans?

[@RainbowAviation]

Sorry about the music I cobbled the video together quickly one night and didn't take the time to work out the editing completely. I don't know if you saw the method or not, we used a water cooled heat sink, pump, and radiator with cooling fans off the shelf computer stuff super light weight, here is a link www.electricmotorglider.com/Progress/Current_progress.html#ESC

[@MrCoPpolice]

Adventure Aircraft Sounds like a batch of angry bees at a Blues Festival. I dont hate Blues. Keep em charged up, and an extra battery :)

[@RainbowAviation]

And continue to apologize for the music. I agree totally it sucks. When this video was made I wasn't much of a filmmaker. I continue to try and up my game. The problem is I've lost the footage for this original video

[@wmtrader]

Enjoy the videos but turn off the music when talking (maybe just get rid of the music), install a forward looking camera (maybe on the center blue spar) and remember that we (or at lest I) watch these types of videos to get a feel of what it is like to do what you are doing and not to be entertained like I am watching a music video. A camera on the center blue spar that looks forward and down a bit would gives us a view of what you see as well as a view of the instrument panel, stick and pedals. You can edit between the wing mounted camera showing you and the spar mounted camera showing the flight controls and your view. Also, are you planing on adding a windscreen to improve aerodynamics?

[@stacase]

Maybe $$$$ is an issue - but yeah a wide angle view from behind the pilot would be great.

[@stacase]

Around 14:00 we are told about the electric motor sound - - - Uh could you have stopped the music at the point and let us hear it maybe? Yeah, I know critics are a dime a dozen. Otherwise nice little airplane - Will the next iteration be bigger with room for two (-:

[@Migueldeservantes]

I believe that if you actually go to your nearest RC club, you'll be able to hear it load and clear! Have a few planes and at the time of taking of... they have exactly the same sound! Yeah you right the music literally took away a great deal of enjoyment of the video! But i can definitely respect their choice, I just lowered the volume so when they talk i increase it...

[@TheLiasas]

So BEAUTIFUL! congratulations!

[@MrCoPpolice]

Very cool..Problem with gliders is they come down, so if you can keep it up it will be worth it as a good form of thermal finding fun. Make sure those heat sinks do not overheat and catch fire. Its the smaller cheaper wire and lack of copper in chinese stuff, as they put most of their copper into their military equipment, more important to them. Damn heat will always be a problem, more heat means coolers, adds weight, need more thrust for the weight, its a vicious cycle. You are living the dream and leaving your mark on society. Hope to see you at Sun N Fun.

[@doffincodger]

Looks an excellent power plant! However a slicker airplane, flying faster would resolve your cooling problems? Consider a canard configuration with a hi mounted mainplane and pusher prop on top. The pilot would seat within the fin/fuz/ mainplane mount, with a canard stab.

[@baldrickscunningplan6154]

Bigger Prop and geared Motor is required. Move more air at the same speed as the Aircraft. High revving small prop is very inefficient. Bit like driving along stuck in first gear.

[@rlb96]

Soooo, the cooling fan is mounted to the motor. You have to leave the motor running to cool the ESC. In the mean time the motor is drawing current from the battery. Current flow is causing the ESC to heat up. So you have to run the motor to run the fan to cool the ESC. Am I caught up in some kind of weird loop here, or would it make more sense to use another method of cooling the ESC after shutdown.

[@Slumberjacksix]

Very interesting aircraft. I enjoyed watching the video. Just a couple of questions. What is the purpose of the 'faring' on the aft portion of the fuselage? Is it only for appearance? Does it not induce additional drag? Does it help cool the motor?

[@RainbowAviation]

First of all, we are capturing any air that escapes around the pilot and we ducted through the motor and controller for cooling purposes. That being said, the primary purpose is for drag reduction. There is more drag reduction to be had by fairing the aft side of an object and there is to be had from fairing the front side of an object. Especially in this case where the object in front (pilot) is already fairly round. LOL. Even without qualitative measurements flying the prototype without the rear fairing showed a significant increase in drag. In addition, the amount of turbulence over the control surfaces on the tail were substantial without the fairing

[@Slumberjacksix]

Thanks.

[@451dskots88]

Like the video but, Let's do it right... Do it right! Over and over... Brutal

[@philalcoceli6328]

Super stable, well built and very stylish glider. Cooling issues would improve much with two motors in tractor configuration on the leading edge of the wins (with the ESC's there too). Also, these tests would work better with some partial windscreen before the pilot as he and the shell behind him act as wind catchers producing excessive drag, a no-no in a glider.

[@RainbowAviation]

Thank your kind comments. Interesting, because you talk about 2 issues the cooling of the ESC's and the motor versus the drag from the frontal area. Have built 2 other EMG-6 aircraft that used the forward fairing. However in this video, we capture all of the air that is not displaced around the pilot and force it through the rear fairing using it as cooling for the motors, controller, and batteries. This powerplant configuration was simply a test of the predator 37 motor and schulze controller.

[@BushPilot444]

Yes, battery fire has got to be the #1 fear and reason for many sensor points among the batteries to send live info to the pilot. No amount of fire extinguisher systems would stop one of those fires either.

[@jolllyroger1]

BushPilot444 I would have a pull lever to dump the batteries and a mirror to see them... Lithium battery fires are hot fast and very dangerous I think it would be good to have a chute attached to the batteries with wire cables so they can burn out fully before reaching the ground to prevent starting wildfire as much as possible I think I would mount the Batts out on the strut as well just be a safer place for said fire to happen and easier to see

[@argonman1]

Great video. Just do it right...... Kill the music, please.

[@angelreading5098]

What a lovely aircraft you have real potential there,what battery pack are you using ? would it not be a better idea to have the ESC in the slipstream externally mounted like we do with model aircraft,rather than relying on afan.

[@paxwallacejazz]

Where's that spray on solar power? All that wing surface should be a solar panel.

[@phlodel]

I don' know about spray on but I've seen information on plastic film solar cells. Develop a covering that is photovltaic. It wouldn't generate enough to extend endurance much but the batteries xcould charge while parked

[@nevillecreativitymentor]

I am working on a GOAT 1 ... your Glider feels amazing ... any advice?

[@denniswilliams8747]

Looks like a nice floater. I agree dump the music or at least subdue it a lot. Thanks I would like prices for the part so I can decide if I want to spend that much

[@bipedalhominid6815]

How much would it cost to put one of these together?

[@kermets]

that doesn’t seem safe to leave motor running you could fall into the pro trip over etc, make better cooling, nice plane

[@DR0NE_BEE]

Drop the music next time. Otherwise interesting video n flights

[@Droneaway-72]

Nice video best watched with sound down

[@tiredlight]

I see an SG38 with modern material? :-) A two blade prop with larger diameter and lower speed could raise the performance as well? That airplane is the right way to enjoy real flying. Greeting from germany.

[@vincentkeller3450]

Landed like a boss!

[@1moredayof]

What a great aircraft! I'm just curious about all the testing and collection of data. Is this a prototype that you're hoping to put on the market?

[@RainbowAviation]

Although we are on prototype number three of the aircraft there are currently beta builders that are building their own aircraft. A total of 20 s/n currently assigned and builders in different stages of completion.

[@skyym3629]

I would think you could make or purchase a cooling jacket that could recycle the coolant around the motor and/or esc and batteries. Would take very little power, maybe its own 2 or 3 cell lipo and the weight should be very minimal. Thanks for the video and info. God Bless

[@rev.andyh.1082]

Love the porno music in the background. I hope he did it right.

[@capnchip]

Neato flying! Neato video! but comes very close to being ruined by the music. Next time just leave it off please.

[@maheshpethe1627]

This is a superb project. is it possible to stretch fuselage to make tandem two seat trainer?

[@RainbowAviation]

Airplane original design is already a two place trainer. We have not yet flown the aircraft in that configuration, but the aircraft was designed as a two place glider with an original gross weight of 750 pounds. Used for training with two people as a pure glider, configurable with a electric power plant and batteries as a single place airplane.

[@bruceking8291]

What is the current status of the EMG-6 electric aircraft?

[@atmm89]

are these planes available for sale or kits thank you

[@ВасилийЛипский-б2н]

I like your project, good work! We are waiting for successful finishing of your flight test. Good luck!

[@paulbeebe9182]

What are you using to get you up to altitude? (tow craft)

[@RainbowAviation]

We have a multitude of different methods by which we tow the aircraft. In this video we are using an old Jeep. We have towed with several other vehicles including a 400 CC Honda four Wheeler. We have several videos also showing us towing the aircraft with a Quicksilver GT500 experimental light sport aircraft rigged up with the tow system.

[@MIKBRI54]

Wow- I am totally new to this kind of thing but I am so enthrawled. Just great. It gives an old duffer like me renewed hopes of finally being able to fly...and not have to sell my wife to do it! What is the cost of this machine??

[@pbounds]

I would rather just listen to the engine and the wind....

[@Amphictyon1]

Dang, man...get rid of that shitty music! You need some help picking background music...

[@RS-sj3fb]

The bit of the video I enjoyed most was that bit where I hit the mute button.

[@debraanderson171]

looks like fun....I like the beat but I don't know if I could dance to it!!

[@MuratAyata]

Wondering how much it cost

[@Nevada_Dan]

Next time, LOSE the music. Thank you.

[@nalaaverroes734]

How many rpm do u have?

[@2idolon]

Really just need to hear the motor ........... Thanks

[@ohwell2790]

For aviation people music is just a pain and is of no use in the video. Please in the future if there is nothing to say, seeing the airplane in the air is enough.

[@miraasee4369]

So this plane pulled in air by vehicle .like a kite or something else

[@jo21e6]

Which battery and motor aré used?

[@stevemcilroy9518]

Is the music your in flight entertainment, or edited on footage? Im looking for cheap flights, do you do meals and movies?

[@johnhernandez4591]

awsome video

[@Armilite1]

So what HP are you using?

[@hadjnabil4811]

THANK YOU

[@avionaaero]

Hey guys, pls did You have to modify the plettenberg motor anyhow?? (Bearings maybe?) Thx

[@RainbowAviation]

No, the goal for this test was simply to see if we could fly the airplane with off-the-shelf model airplane components. It was only designed to evaluate the predator 37 while simultaneously providing additional evaluation of the EMG-6 flight test characteristics. To make it a more practical installation it would probably be best suited for a prop reduction unit swinging a much larger propeller. Had the engine test results been better we would have used two of these motors on the wings.

[@451dskots88]

Just do it... Just do it... Just do it right, do it right

[@MuratAyata]

Prize please????

[@jeff4rofreefight141]

did he do it right?.......

[@richardmyers9386]

could not finish, the music was driving me crazy!!!

[@richardbutt7095]

sweet ride :)

[@pakalolo124]

Nice video..please lose the background music.....it's horrible

[@lud916]

interesting..but the others are right, the music is annoying..

[@bluefishbeagle1]

Cooling fans for EFC why not use ram air it's free.

[@yapandasoftware]

How do you get flaps if you're capitulating their angles in flight? One turns down the other up seems strange.

[@a.p.2356]

I'm not 100% sure what you mean by "capitulating their angles," but this plane does not appear to have separate flaps. The control surfaces on the trailing edges of the wings are ailerons, and "one turns down and the other up" so the pilot can control roll. It may have flaps in the form of flaperons, which are ailerons which can be rotated to increase their angle of attack. This allows the use of flaps without adding an entirely separate control surface.

[@yapandasoftware]

Aaron P: Do they all do this.. Because I flew Cessna 150 and I don't remember the flaps (ailerons) opposing each other for roll.. All I can remember was using my vertical stabilizer on the empennage which caused the outside edge of the wing to lift higher because it was traveling faster than the inside edge. My memory is foggy on this.. I thought the flaps worked in unison to give you more lift at slower speeds.

[@vvogt4252]

Very Cool

[@jacquesvictorleroy7455]

Good Luck at Airventure!

[@dityokurniawan2261]

Damn... i want this one.....

[@digitalmorgan]

why the music??????????????????????????

[@ccraig4art]

loose that music please!

[@garyindiana8037]

That music is got to go..... This could have been a great video but now it's just freaking annoying

[@RainbowAviation]

Thank you for watching, you obviously didn't look at the comments section. You are only number 9000 to comment on the crappy music. It shouldn't be long until we get some good replacement video. Big learning curve on developing videos. The comments are invaluable. Boy did I learned my lesson. Check out some of our newer videos I'm getting better.

[@LaurenTurtles]

i cant think of any thing stupid to say that has not already been said

[@TheDemon190]

Can't understand why your using such a small inefficient prop be better to have a reduction and swing a bigger prop

[@johnnyj540]

Video goooood...music baaaaad.

[@morpheus4340]

... if you wanna make a music video then by all means go ahead, but if you're doing a video on aircraft, maybe you don't need the repetitive porn video music in the background !!!!!!!! Talk about irony... listen to the lyrics in the background song... "do it right, just do it , do it right, do it right.." ;)

[@cowboy6591]

I AGREE , THIS TECHNO, DISCO EVEN LOUD ROCK MUSIC DROWNING OUT THE AUDIO OF THE POWER PLANT IN MOST THESE VIDEOS OUT HERE IS STUPID. THIS VIDEO IS ABOUT THE PLANE NOT THE GAYBAR MUSIC. I WANT TO HEAR THE MOTOR AND WIND THROUGH THE WINGS. Sorry for the caps, to lazy to fix it.....

Everyone agrees with you. The music sucks. Can't find the original footage to edit. I screwed up. But thanks for watching.

[@carlmichelsen1230]

You need to have the comments on both sides of my headset. I cant listen to this

[@tonyhuneycutt604]

turn off that stupid music!! and maybe hear the engine?????????

[@CuzznRickH14]

It's just stupid to have music playing. If we wanted to hear music there are a lot of great videos with thousands of choices. Common idiocy to almost all videos like this. Argh!

Better not stray 800 feet from ending site lol never ever stay from landing Close nearly didn’t make runway lol

[@chucksandos8939]

My dear friend! Designing to e-glider with an electric drive requires maximum reduction of energy losses from air resistance during flight. But your design to install a cockpit behind your back (not in front of yourself) is not only pointless, but also increases resistance due to the air intake by the cockpit as a trap behind your back (above the shoulders). The electric motor from among not too expensive and so does not have the necessary power, but with huge aerodynamic losses of electric motor power it turns out to be very little. Alas, with aerodynamics you obviously are not friends. The trial and error method is a day after day and also takes a lot of money, is not it? ;)))) Excuse me for truth! :)

[@richardchilds4336]

I enjoyed the video & think the design is great apart from the cowling in front of the pusher propellor which would surely act as a scoop creating drag & the fact that the pilot is not strapped/secured in the seat properly but I'm Not disrespecting you as I think you've created a Very fine aircraft.I do understand that the pilot has fabulous access but it could be made safer is what I mean.

[@chucksandos8939]

I have this mean of glider' aerodinamic quality only...

[@24juan68]

Air scooper otherwise it’s perfect 👌

[@vipertruck100]

He is actually reducing the drag behind his back with that cockpit. Since it is a pusher setup there is minimal lost of power.

[@chucksandos8939]

Noting, because it's works Savonius effect and others. P.S. I'm known it very good. But it's very long describe.
