Craycle Orca V2 - Build Fly Crash

[@AerialWaviator]

A nice looking and well laid out design for FPV. 3d-printed planes do weigh more, so do have higher wing loading, particularly at smaller wingspans. The test launches definitely had a very consistent left roll on launch. Hard to tell if torque, or maybe an alignment is off somewhere, or a combination. While TPU is bit heavier, there may be some benefit to using TPU on outer wingtips, or nose. I like the idea of underwing guards to protect servo horns. You did have a nice launch and flight. Not really sure how that was different, but it's an encouraging sign. Look forward to seeing if can resolve the launch challenge and enjoy some more flight time.

HEY! That's how my canard used to fly! Be careflul if you fly it in abandoned Wallmart parking lots! Mine flew into one side of a shopping cart corral, and came out the opposite side in several pieces. After I fixed it, it weighed 15.7 fifteen.seven kilometers. Lol😂

[@billy4221]

I had exactly the same issues with a Hobbyking Tomahawk mini wing, dam thing would not launch, gave up after it became 50% glue, however the best mini wing I ever bought was a cheap as chips foam wing from Banggood, "Dancing Wings" Flying wing, flys so well I just bought another. Thanks for the great videos Andrew

[@tonytruelove3576]

This reminds me of when I started flying power in 70s! You would have been proud of me! All my first flights were just like that😁

[@AndrewNewton]

Oh that would have been messy with fuel flying around

[@Tsnafu]

My mate's massively overweight TBS Caipirinha used to torque roll horribly, the best way we found to launch was grab the nose, turn 180° and hurl it over your head to give it a bit of speed so you had some air over the control surfaces. Any attempt to launch normally gave the same results you saw here.

[@1212354a]

Thanks for keeping at it. I’ve had days like this converting a Predator combat wing to electric. Just kept flipping over on launch.

[@Walt1119]

Reminds me of a bunch of my hand launches!! Now you know why I'm really nervous about hand launching... Anyway, will be watching for your follow up video to get it launched and flying!!! Thanks for sharing with us!!

[@GroundControlRC]

I admire your tenacity!

[@CarlosChavez-gs1ld]

WELL DONE! Especially for the newbies out there,- it is heart warming to see that sometimes things don't work out well, even if you have lots of know-how and experience to bring to the table. This is a hobby filled with WTF!?!?! moments of all kinds. I have been at this since 1979 and have my own thoughts on this particular plane- but no need to bother anyone with that- you have or will cover that in some other video, and, as is the norm, you will do a good job. Keep the blue side up... as best you can!

[@AndrewNewton]

Thanks Carlos. Please share you thoughts because I failed to get this flying, even after patching it up and using the nose hold launch with less throttle and lighter weight.

[@CarlosChavez-gs1ld]

Hi Andrew. I take pride in understanding a fair amount about aerodynamics and basic airplane design decisions, but to this day, the whole concept of the flying wing just fries my noodle. To me a flying wing's state of equilibrium should be that of tumbling out of the sky in an uncontrolled manner, so I can wrap my head around what happened to your model here most of the time much easier than I can explain how and why it flew reasonably well once. All that said, getting to the actual DUT [Device Under Test]- A) As most of us know, the CG on a flying wing is critical, and not always easy to get right. The suggested CG is not always right, and any little mod. can change it. B) That little thing looks like it needs at least 20-25MPH of wind across it to be stable C) There is very little yaw stability here. These things make hand launching it tricky. Some kind of catapult launcher may be useful here. Making yourself some kind of simple and portable launcher for small planes would be an interesting engineering task, and can come in handy in the future. Getting back to yaw stability- the answer to how long a fuse NEEDS to be is how much moment arm is needed to keep the plane stable in Pitch and Yaw given the size of the horizontal and vertical stabilizers and the speed range the airplane will be flying at. The farther back the stabilizers are, the more restoring force they apply. A pure wing's only yaw restoring force is created be the sweep of the wings- which I have never been able to warp my head around. In addition to that, the pitch restoring force is not much better- a body in the middle of a certain length and shape in combination with nailing the CG just right. All this makes for a tough recipe to cook right. OK, so you can add some vertical or "Y" configured fins to help you out, and many wing airplanes and model airplanes do exactly that. Again to my amazement, many of those are not that far back (in one way or the other), but HERE! F&*%!CK me and a half! Those fins are more forward than any other wing design I have ever seen! They are not too far from the middle of the wing!!! What kind of restoring moment is THAT??? This is just my first instinct response here- my gut feel. I like to ENJOY flying, as you did with that nice "RESilience glider" of the last couple of weeks. For me, that is the "MEAT" of the hobby. Trying to make this thing fly is not my idea of fun. I appreciate all you do for those in the hobby- keep the blue side up and thanks again.

[@AndrewNewton]

@@CarlosChavez-gs1ld Thanks for you in depth thoughts. I do like the challenge of trying to get something flying and this is a proven design that has been flying for at least three years. Also can be launched easily and loaded up to 1kg according to the designer. Just that mine did not behave that way, so it must be my particular model or build or handling.

[@scrapveiw]

Thanks for showing us the true nature of 3d printed planes

[@ceziukozak]

i`d fix esc in place. Even 20g moving about in such a short plane can cause CoG shifting in flight. I love my AtomRC Dolphin - fairly long, so you can get away with CoG being not perfect. I had couple of flying wings, not sure if i want one again. I wish you luck Andrew. I enjoy youir channel. Happy flying lovely people !!!! Spring and summer around the corner. Can`t wait 🙂

[@AndrewNewton]

Might be right about the ESC! Good thinking.

[@Tom-wl9sx]

A very nice beginners first plane 🙃😉😷

[@bomberaustychunksbruv4119]

With a lighter 3s and even a simple stabilizer, would be a good flyer by the looks. Like the fact you can now design something like this, I have got onto Fusion and while I'm nowhere near able to design something like this yet, it's great to design and print something usefull out.

[@toolbaggers]

It looks like as much fun as a DLG. 😁

[@AndrewNewton]

Haha, funny man

[@nanomiterctech423]

Just try belly launching instead of holding wing tip .

[@theoztreecrasher2647]

Yep. And just wear a solid butcher's glove like a civilized man. 😉😊

[@skinnyguy3184]

Ive just finished printing and gluing mine together, seams to be mixed views on it, some people just have a nightmare of a time launching and some have no dramas so we will see

[@AndrewNewton]

Keep me posted. Hope you're a no drama situation.

[@skinnyguy3184]

@@AndrewNewton will do mate cheers

[@toolbaggers]

I like to launch wings holding the centerline with no power and I only give it power when I have both hands on the sticks.

[@sUASNews]

I am not sure these 3D prints will work so well in Africa

[@toolbaggers]

The lions will eat them. A plane like this needs nice grass to land.

[@ayoaina_fpv]

Thanks for the video mate! I'll give this one a miss methinks, or wait for their v2? 🙂

[@RobisonRacing68]

Wow... I mean, if you can't fly it Andrew then I have no chance.

[@BrainDeadEngineering]

What hell filament did they use,Titanium ? I never see a printed plane crash so much and live ! lol

[@alperkaya3334]

probably small size and tall grass helps a lot

[@CapnBry]

It flew! Craycle makes some great looking and thoughtfully designed stuff but with 3D printed planes I struggle to get them flying before they are destroyed. 😢 Please do a follow-up because you always seem to be able to figure it out.

[@craycle]

Thanks!

[@mauritz1774]

If you buy the Printet kit, will you get the STL Filies or is it sell seperatly?

[@gflorey1975]

Oh Andrew! I have had the exact issue! once up - flies awesomely - but lands like an egg shell!

[@christheother9088]

Might have saved time to make the whole wing out of tape.

[@AndrewNewton]

Haha, like it!

[@Gavin-qh7li]

Andrew should have made the wing from the box that the kit came in.

[@Dale-sj6ru]

I can never do those side throw style launches, they always end up like that so I don't bother trying anymore.

[@soupdragon5555]

Andrew is the prop on the right way round?

[@AndrewNewton]

Good question, but yes the numbers are facing forward

[@vmaksym]

Why it is so heavy? My 2m wingspan balsa plane has a bit more 6 kg, and I thought it is a lot

[@NorthIceMan]

I have had planes do that king of "flip-n-dive" too heavy. I noticed a 3500mah-4S ? The specs say a 1500mah which would give roughly 120 g over spec Maybe thats the fix needed?

[@jfsaraceno9265]

I bought the model but haven't printed it all yet

[@rjung_ch]

Cheers 👍💪✌

[@lexxdysia]

There's a reason ailerons / elevons are usually outboard.

[@EnglishTurbines]

Too small, too heavy, Elevons need to be full wing length....No wing sweep means its directionally unstable I suspect...Good job you were on soft grass...🤔😳🇬🇧

[@abhisheknagle6994]

nice.

[@iTeerRex]

Lol if it’s behaving like that to a highly experienced person…

[@AndrewNewton]

Still a beginner in some areas, specially little planks

[@sirhilsam]

Too fragile...too much work...too much of a headache. You've got patience bro.

[@allenmoore9848]

Just wondering if the designers actually fly this thing themselves before releasing to the general RC community? Looking at it flying It feels like the size to weight ratio is an issue, especially for low speed stability, coupled with a fragile build material that doesn't have the durability at speed plus the plank wing style with inherit pitch sensitivity and inboard ailerons which are less effective than full length ones. I would be very disappointed after spending my hard earned on a kit like this only to find such issues.

[@craycle]

Wow, this is a harsh criticism. But we are working hard for you to get what you pay for. This is a 3 years old design and flight videos from the first version to V2: kzbin.info/www/bejne/e2OskIN8m92GoNU&ab_channel=Craycle kzbin.info/www/bejne/jH3Sqoinpqd1pbs&ab_channel=Craycle kzbin.info/www/bejne/gWfbimCqgtGMkLc&ab_channel=TroyMcMillan kzbin.info/www/bejne/Y4bUXq16qLOai9E&ab_channel=Skyglide There is more in KZbin.

[@allenmoore9848]

Thanks for the reply, I have looked at the videos in the link and it is clear that it flies. I am actually glad to see that you do indeed fly what you design and try to improve. Andrew is sort of a baseline reference and experienced pilot. If he is having issues, then it is a good indicator. I have followed him for many years and the amount of crap that gets passed of as a good model is astounding. so I suppose seeing this, is here we go again. I hope you will accept my apology for being a bit harsh. All the Best Allen @@craycle

[@IAWS]

Andrew isn't the best pilot. Fact. He's great at videos but his thumbs are not the best.

[@AndrewNewton]

Finally someone speaks the truth!

[@DaniloGarciaHansen]

Muy complicado Andrew

[@dronepilot260rc]

I looks a lot like the morbius wing or whatever it was called

[@AndrewNewton]

That was a shocker, although I could launch that one

[@artemnikitin2806]

you have the short aileron version- too short and too close to the axis of roll, very ineffective at low speed, they guy made the long aileron wings which solved the issue. here is the video of the full wing aileron version flying: kzbin.info/www/bejne/pX2TeJt9oNuSbKs and kzbin.info/www/bejne/q4GceaqKqp2ildk

[@loftbuckleyrc]

Seems way to heavy for its size and wing loading

[@bokusimondesu]

Hmmmmm 🤔 That was a very odd one coming from you Andrew. Seeing you having to give up on a flying machine, or rather give it a rest, before fighting on to get it to fly! Could hear how it was beginning to annoy you just a tad. I have no doubt you'll end up getting it to behave just fine.

[@AndrewNewton]

Well it's patched up again and I'll try again with less throttle and a nose-hold throw

[@archivist17]

Eww! Your equanimity is admirable.

[@AndrewNewton]

Haha, it's all fun and education

[@AntsRC]

I have never had success with 3D printed planes. Never had any 5 of mine that I have printed fly successfully. I think the idea is great for 3D planes but doesn’t work in the real world.

[@CarlosChavez-gs1ld]

Almost fell off my chair LMAO. 100% agree. 3D planes are just plain cheating across the board. I go back to before the days of 3D planes, when "overpowered" meant a thrust to weight ratio of 60% or higher. That number just never stops climbing. Between the efficiencies of todays electric motors and flight times of just 10-15 minutes, it is just too easy to overpower an airplane. Sadly, for many in the hobby, the expression "take off roll" is a foreign and forbidden language. For them, the plane should be airborne in a few plane lengths or something is wrong. I can only hope and pray that there are a few of you thinking "Well gee, how much thrust do you really need?... There you go- the beginning of wisdom is asking the right questions and insisting on getting good answers. Quick food for thought- many of the most efficient planes in the world (B2 Spirit, MQ-20 Avenger, Airbus A380 just to name a few) have thrust to weight ratios in the 20-25% range... and guess what? They don't fall out of the sky!!! Isn't it amazing.

[@FLYWDRAGHIL]

Nothing new here just a wing doing its usual tantrums 😂😂

it's a fad for sure. If anything start ups like craycle are just scamming at this point, user smashes the plane they don't care, they sold some pointless plastic for a profit.

[@michaelwhinnery164]

3d printed models just aren't durable enough and they are almost always heavy. I hope you didn't loose to much money on this one.

[@craycle]

A star has just fallen. I'm sure we will win you over. At least that's what we're working for...

[@IanF-FPV]

Very pitch sensitive

[@Sp3ktral22]

The design is using the wrong aerofoil. A plank like this requires a wing section with appropriate reflex along the whole span. Yes a flight controller can stabilise pitch however this is the wrong design approach and also will hinder efficiency. I don't know the designer however I understand that they take feedback well. Lets see a V2 wing.

[@craycle]

Of course we are reading the comments carefully to get feedbacks :D This is an old design and still I didn't used any flight controller so far. Orca V2 Airfoil : MH 45 9.85%

[@Tsnafu]

Those shit-tier ESCs don't handle 4S at all well. 6 for a tenner on banggood should tell you all you need to know.
