    Electric Plane vs Electric Car

    A lot of fluff in the article. But kinda interesting to see a very early stage race between a car and a plane in Germany to an island. (Spoiler, the car won). https://us.cnn.com/travel/article/eplane-car-challenge/index.html Tim

    Biofuels and composites

    Are there any "safe" composite solutions which can work with biofuels? Specifically ethanol... (my bet is biodiesel is too hard to find an affordable diesel engine). Tim

    DeltaHawk

    An acquaintance mentioned that DeltaHawk has "conforming engines" and is well along the way working with the FAA. The website now has basically no information on it. Just wondering if anyone has any info or updates. Tim

The plane comes up about 10% short in terms of reserve range for a few flights I would like to accomplish running LOP. If I change the compression from...

    Beta Testing

    I have come across a kit builder who has a new model they would like to bring to market, design is done, and they are slowly making the models. They need a beta customer, and would offer a really good discount to be the beta customer. The plane meets or exceeds almost every metric I want...

    Cannot find thread on new engine

    I recall a thread on a new Jet-A powered engine. I am 90% sure it was a turboprop with roughly 200HP. They had a prototype, but wanted to refactor it in a major way with a heat exchange system if I recall. I put a note in my calendar to check on the current status, but I forgot to include a...

    Fixed Gear drag, nose wheel versus tail wheel vs retract

    I can follow that the gear hanging out adds drag. There seems to be some debate how much drag though. Here are the tidbits I have picked up and I am trying to reconcile: Vans Aircraft: across the board, tail wheel to tricycle is only a 2 MPH penalty. Lancair Mako: retract nose gear expected to...

    Due to time constraints in life, my wife convinced me to buy a plane instead of building one.

    Auto Conversion Market

    In terms of auto conversions, at this point lets just say, I know enough that it is currently way beyond my skill level and knowledge to convert a Chevy LS1 or Ford V6.... In my case, the cost of implementing and the time to learn everything is likely more expensive then buying a Lycoming...
