I know nothing!
Ironically, everything I'm learning on this forum I'm learning on the internet....I read on the internet that a large survey showed that most of what's on the internet is wrong.

Thank you guys. Damo RC you mentioned a simple flat bottom airfoil would be nice. Please could you post a link so I can see the exact dimensions. Assuming the chord length is 10cm, what should the thickness be please. Should i incorporate an angle of attack to the wing or should it be parallel to the fuselage. If you are in support of incorporating an angle of attack, what would be an appropriate angle of attack for a plane this size.Proposed wingspan is 60cm
Generally, when there are two conflicting theories, one or both of them are wrong because something is missing from one or both of them. Not long ago, they applied aerodynamic theory to the bumble bee, and proved that it couldn't get enough lift to fly! Clearly, they missed something.About the two minute mark. What he's saying, and I am seriously paraphrasing here, is that yes, we've got all the math, we can build and create and it works. BUT, and it's in caps because it's a big but: Even though we can make lift work, there are two conflicting theories about WHY it works.
The math works because if you build a wing a certain shape, it works in a certain way. WHY it works that way, according to the Bix, is still up in the air. (No pun
Hello guys, please help with answers to my previous questions,
1. Which of the options should I use.
2.If I use the 1st option, what should be the value of x in cm
3. If I use option 2, what should be the values of a, b and c in cm.
Pleeeaaase.
Also I got a quadcopter, ( Airufo sky phantom 2.4G 4CH radio control quadcopter). Decided to use 3 of the motors, one behind each wing and the third at the tail of the B52. Since they will be pusher props I had to change the direction of the propellers and also had to rewire the motors to spin in the opposite direction. The 3 motors are working perfectly now like pusher props.
The issue I have now is with the gyroscope. It alters the speed of the 3 motors such that they spin at different speeds and this is not good. Please does anyone know how to disable the gyroscope? I have attached pictures of the circuit board. Thanks guys
Thank you very much. This is very helpful. Just to be sure, from the drawing you posted, chord length is 4.04+2.83+2.73=9.6cm and wing thickness is 0.8cm at the point where it attaches to the fuselage and 0.1cm at the wing tips right?
I can't let this go. I've said before in other posts that I'm a hard-headed son of a gun. My info came from Bix himself.

That's where I got my interwebs info from. Ya'll take it from there.
Thank you.I have all the respect for Josh and what he does, but as far as I know he's not an engineer.
As I mentioned before these two "theories" aren't mutually exclusive. So there is no conflict.
Both aspects contribute to lift.
If you have an airfoil shape with no angle of attack, you can get lift from the Bernoulli effect.
If you have an air foil with and angle of attack, you get more lift because you add in the deflection effect.
You bet!Thank you.
Lol. Actually bought a whole bundle of the takeaway packs.Hmmmm! Ithink you're going to have to eat a lot of takeaways before you finish that plane. I hope you don't get too fat.
Thanks DamoRC. I wasn't able to defeat the quad's gyro. Would have to manage the motors with the gyro.
