Craycle Orca V2 - Build Fly Crash 

Oh that would have been messy with fuel flying around

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

Haha, funny man

probably small size and tall grass helps a lot

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.

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.

@@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.

Haha, like it!

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

Might be right about the ESC! Good thinking.

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

@@AndrewNewton will do mate cheers

Thanks!

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

Still a beginner in some areas, specially little planks

Good question, but yes the numbers are facing forward

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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-E2I_PFfxSjs.html&ab_channel=Craycle ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VLoyUqqBBoY.html&ab_channel=Craycle ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-K6xY-tMlYZU.html&ab_channel=TroyMcMillan ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE--Uq-zDsNgUo.html&ab_channel=Skyglide There is more in RU-vid.

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

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

Finally someone speaks the truth!

Haha, it's all fun and education

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.

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

That was a shocker, although I could launch that one

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

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.

Tu think it wuz 2 heavy too fly two, Mon Ami? 🤔🙄😁

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%

Good point

You will buy a 3D Printer to make Craycle models in the near future :D

@@craycle I have 3 3D printers, I did B17, to much work. And delicate.

I 100% agree but have fun idc

Yes it's not there yet but unsuccessful experiments are essential to advance

@AndrewNewton very true, you miss a 100% of the shots you don't take.

No it was gifted for review. Still haven't trashed it.....yet
