I Made a RC F-117 Nighthawk (And It Actually Flew!)

- This was a scratch-built F-117 I made from plans I purchased from rcfoamfighters.net. The design is normally for a prop-and-slot, but with the help of a friend, I slapped in the 64mm edf unit from the E-Flite F-15 into the airframe.
It holds true to the nickname "wobbly goblin" and is difficult to fly, but it looks super awesome and sounds deadly. I will continue to slowly modify this airframe to optimize the power system so stay tuned, and thanks for watching! - Фільми й анімація
Congratulations. The intensity of a first solo flight without being in the cockpit. Your curiosity and attention to detail is inspiring for a young man. I suspect a vertical career trajectory.
Nice job getting her to fly as an EDF! I've built this from rcfoamfighters plans 3 times now as a prop & slot. I like your changes and will use them next. I don't have any video of them. The first two flew like bricks and needed full throttle at all times. My third attempt can't get off the ground because she's probably too fat (710g w/out the 3S/2200mAh battery). I didn't realize rattle can type paint weighed so much!
It is a very tricky design indeed. I hope your future builds work out!
Awsome build skills
That was so cool. Awesome tail heavy save!! Top notch flight. Great work you're doing. This is just me barking away at some ideas here. I'd get rid of ductwork in front of the EDF. Then open vents in or just under the canopy windows. The main intake vents, cut out some foam on the fuselage side. More air to EDF and to cool the electronics+ battery. Thrust tubes gradually taper down and are usually 2mm smaller at the exit point. It creates a slight choke point to boost thrust. Length 4× fan diameter. I'd also make the exhaust area a little taller and a bit more narrow(add foam to the inside). AS3X Rx or wing tip for stability. My brain is overdrive. I subbed and hope to see more of your progress with this one.
AirHammer out!!
Really awesome work!
well done young man, I think it was full of cookies! love the fan noise respect from Suffolk, England.
That’s awesome man.
Beautiful Job! Really nice looking and it looked like it flew great. 👍
Outstanding! I admire your knowledge of aerodynamics & your ability to think critically, analyze & adapt modifications for a complex & radical design. You're going to be an asset to whomever you work for in your career. Great vid!
Thank you!
You may be young in age but your mature thorough knowledge of aerodynamics is truly inspiring, I managed to get to grips with the theory of flight when being trained by the RAF in the 80s “ way before you were even thought of” 😂 so know waffle from knowledge, seriously well done !
Thank you for the kind words from across the pond
Looks good, first launch looked to be little tail heavy, put some retractable landing gear and opening bomb bay doors
Very nice!!!
Thank you!
Unstable as hell.....but so is the real one! The F-117 can't fly without computer assisted controls. Impressive build and nice flying.
I heard from a pilot who said it is like super stable and easy to fly.
@@PCcardboard1354 Yes, with computers, like I said. Without them , the airplane is uncontrollable.
@@PoochAndBoo oh yes your right sorry!!!
I’m not an RCer but do enjoy watching them. You’ve certainly thought out every detail on your build!
Thanks Pat
INSANE!!!!!
That is the best sounding, and one of the best looking EDFs I’ve ever seen! Amazing work!
Thank you!
You seem to know your aerodynamics ! Im thinking about getting the Banana Hobby one
Nice job on the Wobblin Goblin.
It flies really well. Congratulations on a successful project.
intake area follow-up in many cases, scale-accurate intakes are Not large enough for an edf. the BEST solution to this problem is the use of larger-than scale intakes.!!!
Try 3d printing a nozzle from the fan to the slit in the F117's rear. The smooth computer generated surface there will help a lot with efficiency & power. If you were using an FMS, QX-Motor, or PowerFun 64mm edf then I could develop it and mail it to you (because I have 64mm fans from those brands).
Awesome to watch! Great job dude. 😎
Bro it looks absolutely fire, good work!
looks great
Great job young man, you should be proud of yourself 👌
Thank you!
Great work and awesome save after that first launch!!
Thanks! Definetly made my heart skip a beat!
Bravo sir!
I’ve been wanting to do this! Great job managing to get an EDF in the airframe and making it work. Also I like your poster board airflow re-direct idea.
Nice going Russell. It does look very cool in flight.
It does look killer!
Amazing drone man! Very cool!
Thank you!
E-flite Should a hire this guy
E-Flite, if you see this, consider this as my resume
everything about a tiny f117's exhaust is a compromise. it should be remembered that a fan/edf does Not like back-pressure; and that is what the f117 exhaust causes. in order to work right, an edf needs three things --- the right amounts of intake and exit area, and an exit duct shape that does not cause excess back-pressure. 12:45 this was a wonky kf profile. in that, the step did align with a 'percentage of chord' line. d
Great job man! New sub here
Scientifically, the F-117 isn't supposed to fly. There's so many computers onboard the full scale craft, it would never fly without them doing their little twists and tweaks, and sometimes against each other. You got yours to fly, that's quite an accomplishment. I just sort of stumbled onto your site because I'm an RC freak too but I fly, the easy ones, Drones, as in DJI Mavic, I have a Mavic Mini with the fly more package and I took delivery of a DJI Mavic AIR 2S with the fly more package, January 11 2021 and I haven't flown it as of today, June 20, 2023. Guess I'm procrastinating. I don't know where you are doing your flying but I'm here in Flint, Michigan. I enjoyed your channel, I'll stop back from time to time, thanks for sharing.
Thank you!
Looks great. Nice save on the first attempt.
Haha thanks, it almost gave me a heart attack.
That looks alot better than the 2 small scale ones ive seen.
Nice job and flight😂😂😊
Awesome build and good flight! Where can I find the RC Foam Flyers channel and store?

Your napkin origami game is on point 👍
Did you know that the F-117 Nighthawk was very hard to auto focus on because off it's shape because the way auto focus works is by Having Light bounce back to the camera and guess what the F-117 is meant to do bounce it away and make sure the radar but in this cause the light to come back to the receiving part, Because of this it would have a hard time because it thinks it is farther away then the real deal.
Very well done. Are you aware the military pilots often referred to it as a wobbly goblin. Maybe you're the next Kelly Johnson.
I get your point but Kelly Johnson was against the F-117's development because he didn't think it would work. Read Skunkworks by Ben Rish, great book and a ton of behind the scenes stories
awesome!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
nice
Id get u a really cheap gyro and turn that aliron expo up to about 90 and that thing will fly like a champ!
I ended up just turning down the throws. Way easier to handle now!
👍🍺🍺 AMAZING !!! 🍺🍺🍺😁😁😁
Sounds like you know more about the swirly air than I do but- Seems like the easiest solution to intake is popping out the windshield and redesign of ductwork and top hatch. Guessing some low-key winglets on the tips may also help keep you tracking straight. Never built an RC anything though, sorry for wasting your time as well as my own. Subscribing to see if I'm a genius 🗿
I think the exhaust ports are a bit too large, in theory they should have the same outlet area as the edf... I think?
The design has little winglets on it but I am a nutcase and I like the scale looks so I decided not to add them! I also made some intake adjustments that will hopefully mean I don't need cheater holes :)
@@beargillium2369 roughly 90% of the intake diameter
@@thatpolishhotdog is it? Commenting on a fairly old video l, but yeah it looked like the exhaust ports were way big(at least by scale), but hey if you say they're 90% I believe you. There's a pretty good walk around of the f117 at an air museum now and the real plane has some really slim ports, that also appear to angle upward quite a bit, kinda like a thrust vector.
Also the bottom has a pretty distinct boat hull sort of shape.
One last thing they mentioned ports above the main intakes on the more horizontal surfaces of the "ducts?" Which are opened during takeoff for increasing airflow, maybe a little plastic tabbed could achieve the same on your RC version and the flaps would just open under throttle when needed.
My two cents, nice plane! 👍
@@thatpolishhotdog edit: those ports almost seem like they could act like a sort of vertical pull lift thing too (I realize I say sort of too much 😁)
very nice model! how is it controllable? do you have a flight stabilizer system on board?
It is radio-controlled. There is no stabilizer.
@@thatpolishhotdog then u are a truly gr8 flyer ... i wudda crashed in less than a second
Nice plane would like to know how you made it.
I dont have any build videos but www.rcfoamfighters.net/ has all the videos for a prop version
you may realize that is the maintenance of a slightly nose-up attitude that makes lift and keeps this model in the air. such a flight attitude tends to impede airflow into the air intakes. this is potentially a big deal because a fan/edf does Not draw like an engine does. d
*** 8:56 NO. cheaters tend to NOT be effective. for best efficiency from an edf there needs to be a minimum of Forward-facing cross-sectional intake area. the minimum efficient intake area value is equal the Effective swept area of the impeller. this value is also equal to The optimal exit area. d

The f117 Flys like shit by default, but it's one of the cooler pieces of aviation history, it's my favorite jet to fly on sim.
Some three letter agencies are going to harass this poor woman.
Bro what 💀
Oh. I thought you were a girl...
Fucking weirdo
