Bird of Prey Maiden Flight!

[@ansiviewer]

While prototyping, create an apparatus to suspend your aircraft, maybe with elastic bands, specifically to determine the thrust angle based on center of balance. I speculated the cost of rebuilding can be avoided.

[@zargonfuture4046]

He's the hight of positivism. "You wanna see it crash?"

[@N827TM]

That bird of play is awesome!! I think moving your fan unit aft will help your CG and will make the fan unit a little more efficient. You will have less friction drag coming out of the duct. I am looking forward to the next flight. Cheers.

[@SKYronGam]

Hi ! Very nice design. We see that the front is hard to lift maybe adding canards in front would help ?? And ad a fun touch of design? Hope the V2 will be a succes like your other planes !! Salute from France ;)

[@ronstiles2681]

With stock cars we have scales to weigh each tire position, perhaps a small digital scale on each corner to help identify balance point

[@RVMD95]

There is no such thing as a failed experiment! You always learn something. Nice flight keep up the great work!

[@phaley51]

Impressive! Cant wait to see V2

[@jvebarnes]

Just an FYI, but back in the day we used to use fishing weights with a file to adjust them. Of course they were made of lead but we didn't know the dangers so perhaps clay or plasticine?

[@alphagt62]

I used to toy with model railroading, and I bought both thin lead sheets and lead shot to control the weight of train cars. The sheets would have been perfect for this instance. Lead isn’t all that dangerous, so long as you don’t make it into dust that can be inhaled.

[@3DPrintHangar_RC]

That thing looks BEYOND INCREDIBLE😍😍

[@Unknown15916]

Love the way that your designs are "step-wise" and "incremental". Could you publish a video about your NOTE BOOKS and how you approach your "design process" ? - Robert outside DC

[@Unknown15916]

Carnards would be something to "play around with" ! Might also open a "can of worms" too.

[@fp-AvERY]

So cool. Don't give up on this one. Can't wait for part 2

[@docr8197]

Add small canard winglets up front ,possibly tied to the other controls for a little more lift and control foward of the wing root

[@gusserflys]

oh man ... great design.. looked to fly well until the elevon malfunction... excellent stuff

[@SamWolfandCo.fossickandfind]

Try the stick on wheel weights the tyre fitters use to balance alloy wheels they're incremental and you can also cut them with side cutters or tin snips , Just a thought with your dilema, Cheers Mate

[@CaptNumbNutz]

As always, I love the design and your ability to scale down machines that multi-billion dollar companies sometimes barely get off the ground. The AA battery as a counterbalancing weight is awesome. It fits right in as a bomb or rocket pod.🤣

[@XxsteamerxX]

If you mount 2 batteries under each wing, they would look like bombs. Plus, adding a lexan canopy might help the cg as well.

[@Elsag_GeliNakh]

🤔It could be a perfect futuristic racing yacht

[@iamscoutstfu]

Don't the droopy wing tips allow it to fly that straight? I wonder if NGAD has that sort of construction, that would allow it to forgo a tail stabilizer

[@gabedarrett1301]

We'd love a video on the build process!

[@delmarrey9077]

Which Remote ID are you using?

[@jaredharris1970]

I would try to find the CG by taking one index finger and place it on the center of the fuselage underneath where u think it would be and try to shift the battery forward and back a bit at a time till u feel like u can balance it on your finger without it moving forward or backwards but do it indoors because the wind might push the nose or tail down or up making u think it’s nose or tail heavy that’s my opinion

[@BusstterNutt]

Interesting concept. thinking about pasting the F16 XL wing on it myself, love the cant on the wings .maybe a canard.?

[@seesafar9912]

Thanks! Looks fun. To help, maybe try computing the CG mathematically before building- total weight (Including batteries etc.) so the CG is plotted? Just a suggestion. Nice build. I wish I had the skill and wherewithal to do that. Good work, Dad.

[@Spetznatz01]

The video and pictures of the real one in Flight showed that it actually had a small ventral fin near the tail. I’m not super if that helped with its aerodynamics or flight characteristics, but I was trying to find out if there real one ever flew without that fin.

[@TinyHouseHomestead]

Stealth is the Way! 😱😁😝🤪👍👍🇺🇸

[@grahamdwells]

for a first flight that was a great success

[@rod3134]

OUTSTANDING ✌🏾 ❤

[@MrMagoo321]

You're the designer of course but my suggestion would be to bring the wing tips up like you said then turn the fuselage into an airfoil to mitigate the cg problem?? IDK just a thought

[@MrMagoo321]

I wrote this before watching the full video

[@flymachine]

Rather than adjusting the wing geometry just make the wingtips/winglets smaller to avoid fouling on landing, I would cheat a little bit and add strakes near the nose, neutral incidence just about 25mm span on each - even with a bit of anhedral - I think that will make a lot of difference

[@bcole4179]

Ever considered using a catapult?

[@abcdodd]

What airfoils are you using for this?

Thats a really cool model RC looks very close to the real thing. I was lucky to see the bird of pray fly twice because i lived next to an airbase it was flown from. the most striking thing about it was just how small it seemed which at the time was very unique, unlike now where we all have drones.

[@MrZeek101]

Great design but I think a little more wing surface is needed you're asking more than that EDF can give great job just the same take care

[@wilgarcia1]

not bad. Pick up a "Flite Test Aura Lite" should keep it nice and in control.

[@kennypinkerton5818]

Make the wing a little longer to increase control surface... you also may want to add a small elevator to the exhaust (thrust vectoring)

[@Allan_aka_RocKITEman]

Great video...👍

[@SmoochyRoo]

It didn't have fly by wire, it instead had manual hydraulic controls. The wings on your model are angled in a way that the downward angled portion isn't providing proper lateral stability like the real one does (the real one is very stable), the inner section needs to he a bit longer and the outer downward section angled a bit mote vertically

[@toolbaggers]

The Avro Arrow (1958) was the first fly-by-wire production plane. It could also be flown RC by ground control!!

[@abcdodd]

I think you're thinking of the drones we flew over lake Ontario. Even those, to my knowledge just had telemetry onboard.

[@dagwort]

It went down like Porkins in _Star Wars_ .

[@pauljs75]

I'm curious, but I've heard something recently about highly efficient as well as supersonic aircraft have a particular trait. Basically that if you took regularly spaced cross-section profiles as seen from the frontal view - that the percentage change in surface area is very consistent between those slices. (There may be some parts that don't change much, but the increase and decrease would be something like a bell curve or parabola?) Some aircraft may be notable for the "coke bottle" waist in the fuselage where the wings increase in area, due to this particular metric. I'm wondering how that works out in some of the replica models you've been making, or if you could specifically do your own take on that idea with something original? -- Edit -- Anyone see a control surface check done prior to sending it? A bit too late this time around though.

[@m14srv]

😂 do you think you will get to ngad ? Would love your ngad vs fa/xx

[@hotlapkyle]

@@m14srv this is the plan! You can see my next move

[@Toby-w2p]

this is great please can you make another tutorial on how you make these planes ?

[@richardgranger1791]

Add wing weighs that look like missiles and guns.

[@trailblazer8380]

Does not look like it would fly, but seeing that you built it, no dpubt that if dis fly 😎

[@MistiMoan]

The game arial ace think it was #7 had this one jet with a delta wing and no vert that at low speed additional wing sections came out and the horizontal tail would bend up. Mmm thinks it was the super wyvern. Can you do a cross between that and your NGAD please

[@toolbaggers]

It looks like it would be a fast flyer.

[@johngoekler1617]

Sand that thing down.. Holy crap.

[@anthonysmith3593]

I've seen the real deal dangling from the ceiling at the national airforce museum

[@qq-uh2mx]

You have built a Bird of Prey RC. I have simulator flown Bird of Prey and modified it and flown with and without karnard wing in X-PLANE. This airframe was a nightmare to fly, ask Boeing who built the Bird of Prey what they say. Iran improvises something similar to Bird of Prey, they ache as it has gone to hell downright slow. But it's brave that you tested and flew the Bird of Prey, well done. But you must have a very expensive and good 3D printer with a very good CAD/CAM program and aerodynamics program as well. Good luck with the other exriments as well. Have a great time.

[@robertharper3754]

Can't wait for V2!!!!

[@zcdat]

Awesome plane 👌 Have you ever considered building F-104 Starfighter? Ps. How did you do at Flight Fest, btw? Any video in the near future?😊

[@JetBirdZ]

Canard ? 🧐

[@allmySena]

you rrrrrrrrrr amazing man

[@SaltonEarth-r6o]

Your CG was in the wrong position, but find the CG position for that model won't be ideal. You need canards, but to a good flying model, you need to move the main wing forward with canards, and found the CG is a quarter of the whole area of the lifting body wings.

[@oscarvandale7775]

Oh man this is sweet!! Would you be interested in doing a collab? Ive got a plane im trying to remake, i got 3d scans of it but still waiting on the email with them. Made a prototype but was too heavy/too little thrust for the wing loading.

[@derekdowns6275]

Make it a canard design.

[@TheUlMaster]

5 mins to fly?

[@AjeebMan]

Bird of prey is siiiiiiccckkk

[@JayL781]

Wing loading is way too high. Looks cool though.

Looks like what you're doing here is pretty great, except the camera work is terrible & annoying. Please get a static camera

Your camera jerks around too much. Take it off of your head and mount it somewhere else. Or stop moving your head.
