Historical moment? Sorry OT, but since discussion veered to DG tax we are OT anyway. |

Doesn't this make the World Class into a defunct, historic curiosity since it has effectively been replaced by the 13.5m class? Historical moment? Definitely! -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |

But isn't there a UK company that is in the process of fitting not only jet but ELECTRIC engine driving wheels of glider that has PW-5 wings? And no, I believe IGC did not have this in mind when deciding on "electrical self launching" capability. |

And no, I believe IGC did not have this in mind when deciding on "electrical self launching" capability. I remember seeing adverts and articles about that, again some time back and nothing recently, so I can only assume that the project imploded. IIRC the guy behind it was at one time the UK AC-4 agent: doesn't have a lot of luck, does he? Thinking about the AC-4M, I wonder if would it be possible to electrify one by replacing its pop-up IC engine and fuel tank with a brushless motor and battery. Even of possible, I suspect it would be left in the dust behind the current 13.5m electric self-launchers, so a fun project if ultimately futile. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |

And no, I believe IGC did not have this in mind when deciding on "electrical self launching" capability. http://www.proairsport.com/news.php The company was wound up in a solvent liquidation, having failed to raise sufficient funds to complete the project. I believe the main director is attempting to resuscitate the project. It would have been the cheapest self launching glider by far, at the expense of considerably less good glide performance than the Silent or other newer 13.5 m gliders. |

Doubt they'd develop new 18m tips. The "neo" winglets are all designed to replace the "flying nun" 15m wingtips on the LS-8, and evidently other 15m LS gliders including the '6? (But not the '10 which already has modified flying nun winglets)
The 18m tips on LS6c really were added to the 15m wings as an afterthought to the formerly successful LS6 racing wing to support a self-launcher version, which never was marketed. |

Perhaps you are referring to the LS-9 motor-glider (which I have seen)? It has a nice tailwheel-in-rudder like later Antares and ArcusM. See ya, Dave |

Upgrading an LS6c from 17.5m to 18m-WL tips is possible (https://www.dg-flugzeugbau.de/downlo...32/TM6032.pdf). You can check with Stefan Göldner from DG about the economics.
