Looking for a two-seater design
that has about 100hp, can fly basic aerobatics safely and cruise at
least 150mph. My reference and comparison of this design is Cessna A150. I want a design that has the same aerobtic capability as Cessna A150 with lighter control(Stick of course!), and flys much faster. What I can think of a Europa (not very aerobatic capable), Avid Acrobat/Kitfox speedster (slow), MCR100 (sophisiticated construction, quoted 5000 labor hours), Sonerai/Sonex (suggested pilot only to fly acro), KR-2(not very aerobatic capable) I know everyone will say, for your mission, go build a RV. Actually, what I want IS a RV--a 100hp RV. Why do I want a 100hp airplane? Because I like Cessna A150, but it's just too slow. I belive with the latest material development and design method, there should be a much improved Cessna A150 type plane. The building cost and ownership of a 100hp RV-type plane is certainly lower than a real RV. If no new suggestion comes up, I will probably bite the bullet to go with a MCR100. A friend of mine is building a Cri-Cri, genious design, so I am sure I won't go wrong with the two-seater MCR100, just a loooong time to build. OR, I may want to be too stupid to design such a plane myself. What's the aerodynamic relationship between aerobatic capability and fast cruising speed? |

Sonex?

RV-9 is not aerobatic. Vans says that very clearly. Pilot only to fly
acro in Sonex according to its specification. Esqual, Pular and Sting are not aerobatic stressed and their companies also said very clearly no recommendation for acro. Toxo seems like a mini Glasair. I will look into it. Thank you Shin |

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 |
