Ming!
You stated earlier that a flying weight of about 3 kilos is fine. But how is that possible? On a conservative side I made up this list (this is not my plane but a guesstimate of total flying weight, done as light as possible
On some of the airliners in one of the videos one of them has 4S 10.000mAh onboard What is their flying weight? Ben_E |

Flap questionQuote:
* How did you manage avoiding landing gear mount? * What is the servo placement for the flaps? Is there one servo or two servos per wing? What is the actuation looks like (push rods etc) * What is the cutting procedure? It would be a tremendous value to see underside of the wing too. Thank you for sharing Doug! You are the master of the high lift devices |

Whats the big worry about the weight? I bet this thing would be fine up to 8 or 9 pounds at least.

Spoilers are held down by tiny springs in flight, and the servo that will actuate them (on Aux 2) will actually not be connected in any way by pushrod or otherwise. It will be evident when I get the pics done. I'll post a couple pictures of my test bed aircraft to show the offset hinges, and spoiler springs I am referring to. In the 737, the only items visible will be the flap servos. Everything else is hidden neatly within the wing and canoe fairings. |

Thank you Doug! Can't wait to see pictures with more details!
I think I got the spoiler and spring idea. Is it possible during the flight, air coming from down the wing above the flap will raise the spoiler? In other words do you need to lock spoilers down with more than a spring during the flight when flaps are deployed? |

where: W - weight p (rho) = air density KG/M^3 S = wing area M^2 Cl_max = Coefficient of lift at stall Or to simplify stall speed is proportional to the square root of weight. For example, let say when plane weights 2kg it's stall speed is 40km/h at 3kg stall speed is 48km/h at 4kg stall speed is 56km/h Which means if you want to fly your plane scale (slow) weigh needs to be kept down. |

My big question is the weight of the airliners we already have seen in the videos. One of them had 4s 10000mAh onboard, the other 3s 10000mAh. Even if my suggested weights might be bit off, I really can't understand how one should get down to the recommend AUW on 3 kg. I'm at just above 4kg... Ben_E |
