I DO remember when you first got the Hawk Sky a year ago. Thats actually why I jumped on it when I saw Nitroplanes started stocking it. I knew what it was once it was here thanks to you!
I bought the Wild HAwk as my 1st plane because of Daves vids. I then, after many crashes, bought the Hawk Sky and I am absolutely pumped that Dave is doing videos about it. I also bought the Spectrum DX6i, yesterday, because of Daves endorsement. Keep it up Dave and Val. I love your videos, they are so informative
Hey Dave... finally got some real flights from my Hawk Sky today... all the info you've had in your videos has really helped, and the twin power system in this video is exactly what i need for my other plane... keep up the good work!!!
Just gone done reading about the "P-factor". I also talked with my friend who is a pilot on the phone. Thanks so much for the tip. I've always wondered if it makes a difference which way twins counter rotate (both "in" or both "out") Now I know! Thanks so much for great tip. Very helpful and a fun study. Learned alot.
I plan to give it more of a "scale" body for added strength. Still very simple though, like we did on our Hydro body. I like the idea of using 2 counter rotating motors to really maximize a hover.
Hey Dave, I'm sure you were just playin but addressing the wires on the LE...We had a 450hp Stearman rigged with video equipment to watch the wingwalker and we ran the wires along the LE...Well we had to abort the takeoff and run the wires along the bottom of the wing in order to do a safe take-off. So it'll probably be noticably better glide if you sink those wires in the foam or run them on the bottom of the wing. Thanks for the nice vids!
if the props are apc, you will usually see the size printed on it for normal rotation. then for reverse rotation, you will see the letter "p" after the size. for example, when you're at the shop looking for twin setups of 6x4 props, look for one that has "6x4" on it, and one that has "6x4 P". the "p" stands for pusher prop.
Great video, I have a converted easystar with brushless motor and ailerons. My wings flexed a lot too, so I strengthen them with a few small carbon rods, just to be sure :-)) . I also did the same with the tail because the plane was hard to control at high acceleration. This plane, or similar ones, have enough lift to carry a normal digital photo camera, I did it a few years ago, just to see if it would work, and it did. I even made a customized canopy with a servo for controls. 5*
Hi! You actually don't need to pop off one of the ESC's middle wire (it's a 5 volt wire). It will just give your servos more thrust in high speeds when a servo has to work very hard, because in such situation voltage drop occurs in the ESC's BEC. Two BECs connected in parallel act just like a normal battery pack - if you connect two of them in parallel you get the same voltage but more power (more current). It will do no harm to your equipment since it takes as much current as it needs. :]
Do keep in mind, not all BECs produce the same voltage (even if same brand), if one BEC provide 5.1V and the other one 5.0V, the 5.1V BEC will work against the other. In some cases it might overload and shut off. But usually when both ESC's are identical, it shouldn't be that big of a problem.
If it helps, i have the same plane and i trimmed the wings down 4in. I got rid of the little curve and to me it has been flying 10times better! more maneuverable and doesnt constantly climb as much which i didnt like.. it has also made it faster. I love it!
@RcWorld7 Yeah around 20 oz. without the battery if memory serves me. I only use the big batteries for FPV flying and that is never boring! Most of the time I use one of the 2600Mah 3S. Its good for half an hour if you are easy on the throttle. The batteries don't really get that hot because the motor is so small and the ESC is on top so it stays cool.
8-} Excellent video! Dave, lots of good content in this vid. That neat stuff on how to hook up dual motors = very informative and I learned a few things. THIS is one of the reasons why I subscribe to your vids. The other is to get a good laugh and enjoy watching some expert flying. Great job, and thanks for another excellent video.
I've been waiting for you to do a twin motor warbird, can't wait to see it. Personally I've been trying to construct a B-25, but haven't gotten designing it.
Oh whoops, I didn't look at that, thanks. I ended up buying the Wild Hawk last summer, and I crashed it once pretty hard and it stopped working, so I called up Customer Service, and what a fun time that was ;), and the rest is history. I ended up taking the components out and putting them with my Dx6i. This Hawk Sky seems like a way better deal than the Wild Hawk, thanks for the review and keep making videos!
It's not made up. Flaps and ailerons are typically independent control surfaces. On this plane, they are a single control surface performing two functions (flaps and ailerons) thus, flaperons
If you measure (or your LIPO balancer displays) these voltages but on the + and - you got 0V, the you should measure on the balancing cable. You should have a 4 wires on the balancing connector and if you take the black one (The last wire) and the red one (First wire of the balancing connector) you should get 12.7V. If this is so, then you may have trouble with the main connector or wires (The bigger wires).
The stick doesn't only go side to side it goes back and forward as well. 40 odd years ago there were single channel sets were the stick only went in one direction but now... Some sets control two functions using two sticks (one side to side, one back forward) but this is not the case here.
I was wondering... If you got 2 motors, you can increase thrust, but the pitch-speed still the same. That is fine for slow-flyers. But, you can use high pitch prop in twin motors, to try to make a setup with the same original thrust but with higher pitch-speed. Maybe you could try use 2 (or 3. lol ;D) motors with high pitch props and 2 cells Li-Po, just to try to find what setup you willl need to use less throttle or/and draw less amps during "not-so-hallucinated" flight. CYA Dave!
Oh good thanks. I've always wondered if it makes a difference which way they counter rotate (both "in" or both "out"). Thanks, I'll give that a Googley-Goog.
The speed controller provide 5V for the receiver and servos via a built-in regulator. Depending on the type of regulators in the ESCs, these may not be happy to work in parallel. One i enough to feed the receiver and servos, so the other is disconneted to avoid a power struggle between the ESC regulators. Most ESCs regulator outputs are happy to be paralleled, though.
I once flew a simulated Beech 1900D and so I think I know something about RC (not to burn all your fuel at once, but rather to keep the fuel burn as low as possible for x phase of flight)
@catamaranman333 BTW....not using the stock motor, it uses alot of power for the amount of thrust you get. I use FC 28-12 from HK with 7x3 prop and 18A stock ESC. IT makes 24oz. thrust @ roughly 10A.
@8Bernice about 10-15 minutes for a beginner pilot with the included battery. Get a larger capacity battery and you can fly for 30-45 minutes possibly.
if they are rotating same direction then yes, counter rotating - no. there are no aux systems running off your motors dave (yet!!) and the bite side of the prop is always the same distance from the center line of the fuselage inducing equal yaw and roll. they are equally 'critical' but neither is the critical.
@RcWorld7 I use either a 5000Mah 20c (fits fine) or 2 2600Mah batteries. Either supply lets me fly more than 1 hour without thermals. I was getting 30min.+ with a single 4000Mah LiPo though.
Supposingly the 2 esc's interfere with each other if you keep the middle wire in. By chopping of one of them it will make one the leader, the other one the follower, and they woill be no fighting no more.
Ha! In this case "flaperons" is a real word. Its when the flaps and ailerons are mixed. See, you are so confused now you don't know what to believe! :)
I think you have a burned out main wire (one of the two longer cables (Red and blac). To be sure wich of these are defect, measure the voltage between: 1. the main RED wire and the black wire on the balancing connector then you should have 12.7V (IF NOT, then the Main RED wire needs to be replaced) 2. the main BLACK wire and the red wire on the balancing connector then you should have 12.7V (IF NOT, then the Main BLACK wire needs to be replaced)
@sampthimo This isn't because of the video, it's because of fail engineering on the speakers. This happens to me too and this is caused by the sound being divided into two sound groups and pretty much 99% of sound is classified as group L instead of being group L and R.
Great video as always Dave/Val ;-) i have nearly the same bird but with a different name thats all and these video's are giving me way to many ideas to play around with mine for when the weather sorts it's self out ;-) 5*
How do you glue those motors on the wings? It would help if you could please make a brief vid on your forum perhaps for some tips and tricks. Did you cut the foam out, and than just glued the wooden motor mount on a piece of depron?
so just to clarify... both props rotating in is the "correct" direction right? btw, i still think you should publish "Dave Aero-Engineering Dictionary" so that we can look up one of your catchy made up words when you use them. great vid as usual
@RCSuperPowers Super baby question here: I have never flown a rc plane before. Im looking at getting into the hobby. On the remote- how can you control the elevation and control which way it leans with one analog stick only going side to side
@theeverythinggeek828 Diameter but, like helis, extra RPMs on a planes prop or rotor speed on a heli acts like a gyro. So you actually want the largest diameter prop you can fit pitched LESS so the prop turns more RPM....
I niticed that on landing, it would be very easy for the prop to dig into the grass. if that were to happen with this heavy foam that you speak of, could it snap a prop blade, or would it just skip?
@bestog2000 Lol...I'm kinda embarrassed now that I figured out what the problem with my motor was. I couldn't figure out why when I tightened the screws more to place the motor ...the harder it was to turn the prop by hand. It got to the point where if I tightened the screws two much..the prop would barely spin...turns out there was hot glue that was hardened pressed up against the shaft on the back side of the motor. I removed the hardened glue..and now both motors spin up fine :)
Just thought I'd ask for some advice....what Interests me are FPV approaches.. using OSD its fun to "match numbers" - ( you know speed.angle, glide slope etc ) to get as accurate a landing as I can for a model. I want to do is get into flying large, slow to medium speed RC's with Twin motors. do you think that plane ( with landing gear of course ) would be a good choice for this purposes? - if not, then what would you suggest? - I'm not an aerobatics type of person....your thoughts please.
@rcplanesofma24 i think you can get a vtail mixer and then mix it like that plug 1 wire into channel 5 and 1 in the ailrons channel 5 is nomallyreatracts buts that all you need
Got my HakwkSky today but after second crash (and second start:) the motor didn't work anymore *shocked* ... one of the black wires was disconnected ... *puh* When do we get a video with wings cut? I like your videos!
I DO remember when you first got the Hawk Sky a year ago. Thats actually why I jumped on it when I saw Nitroplanes started stocking it. I knew what it was once it was here thanks to you!

Keep it up Dave and Val. I love your videos, they are so informative
I love dual prop setups and the 3 bladed propellers. You did a good job and looks like it flies well to boot!

Looks nice over there in Oh-Regon.
Nice plane. It makes me smile when I see one of those all pimped out. :)
My grandpa flew P-38 J's in WWII for recon. He dreamed from a child to fly one and he got his dream. I can't wait to see it
I plan to give it more of a "scale" body for added strength. Still very simple though, like we did on our Hydro body.
I like the idea of using 2 counter rotating motors to really maximize a hover.
Nicely done, Dave. I personally think the 8x4 setup looks better (aesthetically) than the 6x4. It just looks "right" to me.
Hey Dave, I'm sure you were just playin but addressing the wires on the LE...We had a 450hp Stearman rigged with video equipment to watch the wingwalker and we ran the wires along the LE...Well we had to abort the takeoff and run the wires along the bottom of the wing in order to do a safe take-off.

your take on a P38 would ROCK! can't wait!

cant wait to see your p-38 thats by far my favorite WWII fighter
2024 here , getting back into the hobby and getting some nostalgia

Excellent presentation Dave. Very nice.
Bill
As always, Nice Job! Plane looks cool with the twin 3 bladed props. Great Video!
@RCSuperPowers great work MR Powers. also nice to see you now have on board filming which I think is a great improvement
@RcWorld7 Yeah around 20 oz. without the battery if memory serves me. I only use the big batteries for FPV flying and that is never boring! Most of the time I use one of the 2600Mah 3S.

Great to know about how to properly setup the duel ESC's !
I've been waiting for you to do a twin motor warbird, can't wait to see it. Personally I've been trying to construct a B-25, but haven't gotten designing it.
One thing I really want to try when I finally get my Hawk Sky is attaching dual EDF fans like you see on the A10, see how that goes.
Yeah, its something to do with the "BEC" of the speed controllers. I don't fully understand how that works, but unplugging one of them is the trick.
Oh whoops, I didn't look at that, thanks. I ended up buying the Wild Hawk last summer, and I crashed it once pretty hard and it stopped working, so I called up Customer Service, and what a fun time that was ;), and the rest is history. I ended up taking the components out and putting them with my Dx6i. This Hawk Sky seems like a way better deal than the Wild Hawk, thanks for the review and keep making videos!
Thanks Dave/Val, keep up the good work, enjoying the Hawk Sky vids.
0:13 u should make a 3 propellor/motor wild hawk with the pusher stock and the 2 new ones. that sucker would go so dang fast.
It's not made up. Flaps and ailerons are typically independent control surfaces. On this plane, they are a single control surface performing two functions (flaps and ailerons) thus, flaperons
Omg
o very nice when the weather clears up mine will fly. keep the videos comming.

You should have a 4 wires on the balancing connector and if you take the black one (The last wire) and the red one (First wire of the balancing connector) you should get 12.7V. If this is so, then you may have trouble with the main connector or wires (The bigger wires).
Actually, fully charged 2cell pack normally reaches 8.4 volts (4.2 volts per cell).
great video, your right, i had no clue it was that easy to wire two motors, great job flying and great job on the vid.
The stick doesn't only go side to side it goes back and forward as well. 40 odd years ago there were single channel sets were the stick only went in one direction but now... Some sets control two functions using two sticks (one side to side, one back forward) but this is not the case here.

CYA Dave!
You're gonna do a P-38? SWEET!
@NiclasTHOREN take the esc and put it over the canopy,so that it will have an air flow to cool it down.
Oh good thanks. I've always wondered if it makes a difference which way they counter rotate (both "in" or both "out"). Thanks, I'll give that a Googley-Goog.
You DO know these things run on smoke? If the smoke stays in, it's OK. If the smoke gets out, it won't run ;-)
Good vidz, enjoyable and informative.
The speed controller provide 5V for the receiver and servos via a built-in regulator. Depending on the type of regulators in the ESCs, these may not be happy to work in parallel. One i enough to feed the receiver and servos, so the other is disconneted to avoid a power struggle between the ESC regulators. Most ESCs regulator outputs are happy to be paralleled, though.
Always use your face to determine temperature of your electronics!!
LMAO!!!
@rcramosrc
YEP! Because you need only one BEC to power up the Rx and the servos.
I once flew a simulated Beech 1900D and so I think I know something about RC (not to burn all your fuel at once, but rather to keep the fuel burn as low as possible for x phase of flight)

@8Bernice about 10-15 minutes for a beginner pilot with the included battery. Get a larger capacity battery and you can fly for 30-45 minutes possibly.
Yes. Scott is building it.

Thanks Weather Guy.
The ending almost made me laughy-pee.
this is when i first learned to fly
Hey Alright!
This is awesome, I think I will be getting one. RC planes are so hard to find in the UK...
RC Powers UK perhaps, dave?
I put a note in the sidbar for ya on that.
Scott is working on the VTOL.
I think you have a burned out main wire (one of the two longer cables (Red and blac). To be sure wich of these are defect, measure the voltage between:
1. the main RED wire and the black wire on the balancing connector then you should have 12.7V (IF NOT, then the Main RED wire needs to be replaced)
2. the main BLACK wire and the red wire on the balancing connector then you should have 12.7V (IF NOT, then the Main BLACK wire needs to be replaced)
This is awesome!! Great vid!

Can hardly wait to see your P-38 style plane.
Do you plan on building it like a basic Foamie?
OMG I was waiting to see this !
Ha, cool thanks, glad you like it.
thanks for the great video! Lots of good information! (and you didn't have to crash the plane to make it interesting!)
@RcWorld7 Yeah, FPV is a whole new ballgame! About $120 will get you started. It's well worth it!
I guess they can be if they are counter rotating.
the hawk sky and wild hawk are located at the wbsite: nitroplanes
Yes, exactly right!
Great video as always Dave/Val ;-) i have nearly the same bird but with a different name thats all and these video's are giving me way to many ideas to play around with mine for when the weather sorts it's self out ;-) 5*

@BlueTigerPs3 Ah you got me. I just taped the camera on later and edited it in. I don't think it was even filmed on the same day.

whoaa that was awsome!
Lmao love the ending...
@DaveESPI
you only want one of the BEC's on , have both on and they'll have a freakout
Nice plain one of the best..
i like how a dialog says it doesnt increase overall speed and then he says its plenty fast
@rcplanesofma24 i think you can get a vtail mixer and then mix it like that plug 1 wire into channel 5 and 1 in the ailrons channel 5 is nomallyreatracts buts that all you need
don't you listen, more motors doesn't equal more speed, just more acceleration.
you should make it a 3 motor plane with the stock motor and the two micro jets
Got my HakwkSky today but after second crash (and second start:) the motor didn't work anymore *shocked* ... one of the black wires was disconnected ... *puh*
When do we get a video with wings cut? I like your videos!
To keep the battery cool couldnt you add like a roof scoop lol?
wow great video keep em comming.
John
@RCSuperPowers
ok, so you can use the flaperons as flaps AND as ailerons? i love your videos though! when are you going to cut the wings off
