Just looked at Toxo website a little more carefully and I feel some
suspicious. They quote "maximum 230mph, stall at 40mph with Jabiru 3300 120hp" And there's no weight information at the website. Maximum and stall speeds ratio almost 6:1? Tooooo good to be true. |

Maximum and stall speeds ratio almost 6:1? Tooooo good to be true. Depends on what they mean by maximum. A ratio of 6:1 for max cruise over stall would be pretty magical. 4:1 is more like it for a good homebuilt and few spam cans attain 3:1. However, if they are talking about Vne, then 6:1 might not be so unreasonable. Matt |

The 230mph maximum speed is in Mooney's press release so it shouldn't
be a typo. We'll see. |

Note the 230mph maximum speed is in Mooney's press release... We'll
see. |

Not many aircraft (other than special purpose homebuilts) actually achieve a
top speed:stall speed ratio of 4, much less a max cruise: stall speed ratio of 4. Of course, some consider max cruise to be maximum speed at any (read "low") altitude. Examples: Aircraft Top Speed:Stall Speed at gross 150 HP RV-3 4.1 180 HP RV-4 3.9 200 HP RV-8 3.8 160 HP RV-9 3.9 260 HP RV-10 3.3 The typical RV-3 that is going that fast is operating at well over the 2700 RPM where the engine is rated 150 HP. The prototype GlaStar was designed and flown successfully with the O-240. BJC Depends on what they mean by maximum. A ratio of 6:1 for max cruise over stall would be pretty magical. 4:1 is more like it for a good homebuilt and few spam cans attain 3:1. However, if they are talking about Vne, then 6:1 might not be so unreasonable. Matt |

If the airplane stalls at 40 mph, then it stalls at 80 mph at 4 G's. This same airplane would stall at 16 G's at 160 mph. 230? Get real, small gusts alone would kill you at that speed. One or the other (or more likely both) of those numbers is pure fiction. To paraphrase an old saw: "There are lies, damned lies, and specifications for homebuilts". -Bob |
