Status: offline 		Big plane's maiden flight and they're taking off on a grass runway with a lake on one side and a building/parking lot on the other?

What a bummer, but these guys are just plain lucky someone wasn't seriously hurt. I felt the same way as other posters when I saw the engine run-up right in front of a bunch of people, then the takeoff came right at the camera guy, and then the plane flies over/behind the parking lot. Talk about risking a lot of injury/property damage on a maiden flight.

Too me it looked like a combination of being tail heavy, not enough airspeed on takeoff and not a lot of control surface authority, plus some guy on the sticks that appears to be more of a builder than a flier.

They could have easily ended up with a Darwin award. Dumb-luck kept it from being much worse.

And I second the motion that all crash videos should actually show the crash.

Status: offline 		I reckon what happened to this aircraft is the same as what probably happened to the B52 giant scale we have seen videos of.

If you look at the turn he is making, it's not a coordinated turn (that is, it's yawing away from the turn) and the inner wing looks like it's stalling. The natural reaction is to give right aileron away from the turn, to try to correct the steepness of the turn, but all that does to a near-stalled inner wing (now, with a down aileron on it) isn't just more lift, but more drag (increase lift = increased drag) thus making the inner wing 'dig in' even more.

I believe a full scale B52 crashed fairly recently for exactly the same reason. Badly coordinated turn (that is not using the rudder to yaw into the turn) = inner wing stalls.

My 2c!

Status: offline 		There was a full size B-52 that carshed in the mid 90s, too step turn to low. Resolting inn a wing tip stall. I cant belive this idiot putting in 40cc engines , and that he took of on that runway. And then turning into an area that there was a pariknig lot, why not turn towords the lake. He was damb lucky that no one was hurt.

Status: offline 		Mac Hodges has a B-29 with a 20(+-)foot wingspan and he uses all four G-80's in his. It has plenty of power to get it moving through the air. I was at the Ft. Benning Fly-in this past weekend and watched him fly his massive B-29 along with the X-1. The X-1 suffered some damge during the rocket ignition stage, but was recovered in the cotton field without further damage.

I do believe it was a mixture of wrong size engines and using more than one type of engine. This would of lead to slower than normal operating airspeed. Anyways, that's all I have to say about that.

Status: offline 		Your guys' responses to this video are fascinating....

The purpose of putting this up here is so that we can learn and make better descisions about our own airplanes and approach to flying.

In response to a few posts back, the pilot intended to fly the plane in a straight line. Due to assymetric thrust or bent tail, the plane was yawing to the left causing it to turn to the left against the pilots inputs. If you watch teh video closely, you will see right aileron during the entire flight, but the plane continued to the left.

more info: to the right of the cameraman (during takeoff roll) is a barn structure where onlookers witnessed the flight and crash. I agree it is too bad the plane descended behind the cars prior to impact. So the takeoff happened between the lake and the barn. Regardless if there is a structure there or not, the plane could have turned into the people (like you guys are discussing).

Good point... wouldn't want to lose the important stuff...

Either way...it is sad to see such a beautiful model lost because of what appears to be (at least to a complete n00b) several bad decisions.....

but.......as they said..... We can rebuild it....

I am sorry to see such a beautiful plane go down also. I have to agree that it looked like the plane did not have enough power on takeoff, but I alas, am just a newbe to this hobby also and I don't know anything about the big planes. Haven't even flown my trainer yet.

Looks like I live just around the corner from you.

Status: offline 		Theese who pilot big planes, do they not study howe the fulsize counterparts behave? Thinking of rudder/ailron use for one. Anyway it must hurt to know your masterpiece was not up to the task of flying. Especialy when you know it is your own dam foult.
