Couple of posts before, there was a question about the type of bearings the stock DJI motors are using.
Naturecannon (rcgroups user) have sent me this info about them: http://gothelirc.com/shopdisplayprod...2&cat=Bearings ABEC5 3x8x4 mm bearings (2x) sku: S693ZZ If anyone needs replacing, of course. |

14 miutes in the air with single battery and total weight of 1480grams
14 min single battery flight video
Apologies for the scary face at the beginning of the video,
Just tried how long I can get with my F450 fully loaded on 1 battery charge. My setup in the air: F450 from uavproducts.com Stock DJI motors Stock 10" props Naza w/out GPS FPV 5.8 Ghz 100 or 200mV Vtx Cloverleaf antenna on Vtx GoPro HD1 Cyclops Easy OSD with GPS module Turnigy 3s 30-40C 5000mAh battery GenAce 3s 450mAh Vtx/OSD battery Landing gear made of arrow shaft (7.5" high) Total weight in air - 1480 grams Motors temperature after 14 mins of flight - 90F On the ground: FPV 5.8Ghz Vrx Eagle tree Diversity Przim 7" LCD with build in battery VuPoint recorder, who for some reason betrayed me. I think I pressed the record, and instantly stopped it, so I have no recording from it at all. |

Another good source for bearings is RCBearings.com. They have many sizes, styles and quality grades and their prices are good. If they don't have it, they will get it for you. |

More Info
I'm sorry, but your question might sit unanswered for some time if you don't give us just a little more information.
With what little you've given us to go on, I'll guess that it's the spongy ground your trying to land on... Seriously, we'll try to help you if you'll just help us a bit... |

If nothing else, you've been rubbing elbows with all of us long enough for something to have rubbed off. I hope that something doesn't stink too badly... |

It's not like it has a sonar to actually know where the ground is. The failsafe isn't supposed to be the lazy mans landing system, it's supposed to be an emergency return to home feature.

Gentle BouncingQuote:
The few times I've tested RTH, I've seen the "feeling" type bounce. Then again, there's the violent bounce that slams the airframe down so hard it makes you think it's trying to self destruct. Like I posted, we don't even know the severity of his bouncing... |
