    DIY 400 year nuclear battery: Electric Aircraft Recharging Challenges Solved ;)

    I've often wondered why we can't use nuclear waste as a power source. A solar panel converts solar radiation into electricity after all. (and no, I have no idea of the science involved)

    Kanardia

    I've flown an aircraft with a pair of 3" Kanardia Horis units. This aircraft was otherwise all steam gauges. I liked the fact that they fit in a standard steam gauge hole, they could be configured to show different information and in EFIS mode, they showed the essential information in the usual...

    Any new technology concerning flying boat amphibians with foldable fings..?

    Have you seen these guys? Gevers Aircraft - Genesis Triphibian I don't think the website has been updated since I first discovered it over a decade ago. But intriguing idea

    Totally new type of IC engine.

    I'm no engineer, but as someone with a 40HP single cylinder motorcycle, I'd think that a single cylinder engine producing 90+ HP is going to be a hell of a thumper. Hard on props?

    Totally new type of IC engine.

    Range extender for an electric aircraft maybe?

    Textron buys Pipistrel

    IMO this is what they should have done in the first place (not necessarily Pipistrel).

    DeltaHawk

    I've been watching Zoche, DeltaHawk, Dair, Wilksch, etc. for 20 plus years. Quite honestly, I think electric motors will get here before we have a mass-market diesel. They might as well pack up and go home. And I say that as a diesel fanatic.

    Restricted areas times and altitudes

    Hi Guys, Covid has prevented me from visiting the USA for two years now and I was doing some flight planning to refresh my brain. It occurred to me that my preferred flight planning App doesn't have any way to lookup the active times or altitudes for restricted areas. Google was spectacularly...

    O-100-- interesting new engine

    Very sad news. I was never in the market for either an O-100 or a CrackerJack, but that didn't stop me cheering him on from the side lines. We need more Pete Plumb's. He is going to go down as one of my aviation heros. Best wishes to all his friends and family. Grelly

    Lets talk about diesels.

    There are others too in the opposed piston diesel arena. Mostly with no updates for years. Dair, and Weslake for a start. I have been particularly disappointed that Superior Airparts haven't made more progress with the Gemini.

    Electric SSDR Motor Glider

    Just a couple of thoughts... Another airframe you might want to look at for inspiration is the Europa aircraft. In its monowheel form, the outriggers are fixed to the flaps. So flaps up there is a measure of stream lining. Flaps (and outriggers) down for landing. The limitations of a...

    Lowest cost AHRS EFIS/6 pack replacement?

    I'm not sure if they are available in the USA, but Kanardia Horis is in that ballpark.

    How wide for a side-by-side?

    For those wanted to transport 8x4 sheets, I have seen a few designs with a cargo pod strapped to the belly. The Comp Air 8, for example. It's an idea.

    How wide for a side-by-side?

    If you are designing something, you could always stagger the two seats enough that shoulders, elbows and hips don't need the same space. To answer your question, I guess I am about medium width-wise and I find a C172 adequate. So 42 inches would be my design goal.

    Excellent. Well done Pete & team.

    language advice from my European friends

    Most European countries teach English as a second language if not the first, so you can get quite a long way without knowing the local language at all. However, a few words shows willing and is usually appreciated even if they give up and use English in the next sentence. I would say the top...

    O-100-- interesting new engine

    You're all wrong. The oldest saying in aviation has to be "Holy cr*p! It flies!"
