| Can you really scratch build a two man ultralight airplane from bamboo? MacGyver did it - can the MythBusters Build Team?
Talk About It Here!

Registered: 01-17-08 | ok simply put the design was attrocious I think if you greatly refined your design you could sustain at least limited flight.
the wings were way too fat they probably blocked as much air as they passed.
the frame im not sure how close it was to the mac episode but it seems like that could also be mush more effecient. |

Registered: 02-20-08 | As a model airplane pilot i caught a few really big mistakes they made.
first mistake, the ultralight was tail heavy, even if they had enough speed to fly it would crash, they should have balanced it for it to have a decent chance of flying.
next mistake, the airfoil on the wind was way to big, it should have had half the height it did as well as they enclosed the bottom of the wing with more trash bags which only added unneeded weight.
Last mistake, the big one, they never should have tried taking flight off a cliff without a lot more ground speed. |

Registered: 11-29-06 | Just watched that part of the episode. The design was too heavy, but despite that it almost worked. When the ultralight first went over the cliff, it actually started to glide. Whoever was on the controls blew it and turned the nose down.
Here's what needs to make this one work. 1) Clean up the design 2) For that short of a run, the drop off needs to be steeper and have no protusions 3) Get someone on the controls that is an experienced (and good) at RC aircraft.
As a note, I've flown several styles of ultrlights. The engine was plenty of power for the flight. |

Registered: 02-20-08 | i think by downsizing the tail they lost weight to allow a more even and straught flight path and the extra lift on the tail might have also helped |

Registered: 01-09-04 |  The Bamboo Goose needs more SPEED and a good updraft to fly or it will never get off the ground. It's too chunky. I suggest you revisit this and take the bamboo goose to Fort Funston, just south of San Francisco- before Daly City on the coast highway. Let it hang ten with the hang gliders on a good windy day. That breeeze comes in off the ocean, hits the cliff and has a great updraft. |

Registered: 06-05-05 | My thought on the ultra-light is that, yes they didn't quite nail the airfoil design, but the most important fault was the location. From the film clip, it looked to be a cliff a couple of thousand feet high. the one feature that you might find there as opposed to the quarry are updrafts, or columns of warm air moving up, making gliding easier. Also, If you watch the mythbuster episode the ultra-light looks like it is gliding fine for a couple of seconds when the tail section hits the side of the cliff, which is more of a steep grade than a sheer drop. I think it should be reclassified as plausible rather than busted. |

Registered: 02-20-08 | i watch your show every wednsday to see what youve got in store. ive noticed when your side kicks (haha) built the ultralight when they rolled it off the side of the cliff it seemed to almost take flight. it started to even itself out until the tail of the plane hit the side of the cliff, losing its stability and falling to the ground. I believe if yall would have rolled it off a higher cliff and a steeper cliff giving it clearence for it to take flight. Cause i believe it would have taken flight if that was the case. LETS SEE IT! |

Registered: 02-20-08 | Alright, first off i watched macguyver alot (and i mean ALOT) when i was little. i use to have my mom speed to my house so that i could watch it. so i almost know everything, so the design was fine but the location was bad. in the original episode the cliff that macguyver used was steeper and may have produced updrafts. the cliff used was at a slop, not even close to be called a cliff. my sugestion rebulid the glider and try a new location were it is a cliff and where there is a slight updraft being produced. |

Registered: 12-26-07 | THE KITE!!!!! you must have had a hint because at first you had it wrong with the pipes on the front, then when you actually got it you had the pipes on the back!!! |
Junior Member
Registered: 02-20-08 | If you watched carefully, the ultra light was flying.
Quite obvious though that the motor did not have enough speed to keep flying, just glide.
Bottom line: Revisit the myth, the tail hit the cliff. |

Registered: 10-09-05 | It looked like it was flying for a second, until the tail hit ( the not so sheer drop off )
If you guys try this myth again, find a drop off of more than 100 ft. |

Registered: 12-26-07 | I think the ultralight could have worked with a better design and a steeper cliff. I vote for a redo! |
Junior Member
Registered: 12-26-07 | Yeah, I definitely agree with the comment about the updraft. |
Junior Member
Registered: 02-20-08 | they totaly need to redo that myth!!! for one the motor was all wrong and the cliff was all wrong !!! the fram seemed to be built well but everthing else was just not right!!!! |
