Or you'll be history. Or something like that. Now, where did I leave my Segway... There's no law saying that investors have to be smart. T8 |

I want to see just one of these pipe-dream machines get a standard airworthiness cert. with the OK for carrying passengers, just one. Just like fusion power (and Trump's healthcare plan), it's only a short few years away, I guess. |

Oh that is so last decade. I've got an InMotion V11 instead, and the
bruises to prove it! Dan 5J On 2/25/21 10:32 AM, Tango Eight wrote: Now, where did I leave my Segway... |

I noticed one of the other Silent 2 Electro owners was fishing around to buy an ASH31Mi, a gas guzzling Schleicher product. Grass is always greener on the other side. Maybe Eric and that guy could work out a swap, then they'd both have their dream ships :-) |

Right on, Dave. I want to see just one of these pipe-dream machines get a standard airworthiness cert. with the OK for carrying passengers, just one. - I know of one being close. Look up Joby. Just like fusion power (and Trump's healthcare plan), it's only a short few years away, I guess. - Kamala has a health plan for you Herb. Unfortunately, You and Me as white males only get to pay for it, but Hey now! It's a true realization of Marx&Engel's dreams and it covers the entire Central America. Best, GK |

Even on the original, pre-Covid schedule, it would not have been ready for the Seniors. And consider this: my current motorglider, the ASH26E, was delivered a year late by Schleicher, so by that standard, GP still has until Feb. 2022 to get the new glider to me :^) There are a lot of FES gliders out there now, and with all the manufacturers offering them, there will be many more. The more powerful electrics with mast mounted propellers are also offered by all the manufacturers, and many pilots that think the FES gliders are appealing but marginal will be ordering these new gliders. I think you will see a lot of Kool-Aid drinkers behind the Schleicher, Schempp-Hirth, and Jonkers booths at the SSA convention in 2022, all offering what you saw - and desired - in the Antares years ago. They won't make the same mistakes that Lange made. -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) - "A Guide to Self-Launching Sailplane Operation" https://sites.google.com/site/motorg...ad-the-guide-1 |

Yes, and I've been laid up for the past week after a horrific spill. My
helmet and pads protected skin and skull, but not the ribs from a good bruise. Now it hurts to laugh (really) and I'm impatiently waiting for the pain to subside so I can mount up again. Pretty sure I can fly the gyro without problems, but getting in and out of the thing will hurt...
