I read in Avweb that a predator crashed, recently.
Anyone wanna make a bet, that it's Rotax puked? g Sorry, everyone. I couldn't pass up the opportunity! :-) -- Jim in NC |

I read somewhere that 1000 hours has rarely been exceeded before some glitch or other stuffs them into a hillside or cornfield even without being shot at. That seems a little strange. With a reported price of 6.8 MILLION Dollars, I would think reliability would rival the best of small aircraft. Which begs another question. Why are they using a relatively cheap engine, like a Rotax, in such an expensive vehicle? -- Jim in NC |

The fighter pilot denied it, claiming he'd been in straight-and-level flight several thousand feet up. Fighter pilot, however, could NOT explain why the rifle bullet's exit hole was only slightly higher on the left side of the fuselage than the entry hole in the right.... Ron Wanttaja |

Are you sure it's Rotax powered?
Last RPV I saw up close on the Arizona border used two Moto Guzzi 650CC motorcycle engines, with GM alternators grafted on the motors to replace the Guzzi alternators. (Boy those electronics must pull some juice!!) Sounds like it was on the same area that we caught up with it on, when it crashed. You should see some of the fun stuff that flies around here in the vast spaces. Bart D. Hull Tempe, Arizona Check http://www.inficad.com/~bdhull/engine.html for my Subaru Engine Conversion Check http://www.inficad.com/~bdhull/fuselage.html for Tango II I'm building.

Add flight control actuators, nav receivers (GPS mostly now), telemetry, on-board processor, TV cameras and transmitters/recorders, gyro stabalized lenses, waldos to work all that, and a transponder in a Pear Tree... THEN start talking about radar... Yeah, they pull some trons. But never heard of the motorcycle engines being used. Way way too much money in the pot now for that. Almost all current UAV engines run on Jet-A. DoD requirement... |

It was a Pred B.
"The turboprop-powered Predator B, designated MQ-9B by the US Air Force and referred to as the Hunter-Killer, flies faster, higher and carries more weapons than the Predator. The Honeywell TP331-10 engine, producing 950 shp, provides a maximum airspeed of 260 kts and a cruise speed for maximum endurance of 150-170 kts. The MQ-9B can carry a payload mix of 1,500 lb. on each of its two inboard weapons stations, 500-600 lb. on the two middle stations and 150-200 lb. on the outboard stations. " The only thing it has in common with the Pred A is they're both made by General Atomics. It's huge. Reliability is a problem. Hull insurance for your normal GA airplane is going to run about 1.5% of the aircraft's value, per year. Hull insurance for a UAV is about 15%. |

Yeah, but your typical Cessna 172 can't carry...."a payload mix of 1,500 lb. on each of its two inboard weapons stations, 500-600 lb. on the two middle stations and 150-200 lb. on the outboard stations."
