    None of the above are required for VH day VFR, but they are a nice-to-have and anything that makes you more visible is good, particularly in the circuit.

    Jet A1 isn't available at most airfields where you might want to operate that type of aircraft, so that could limit sales even if you could afford to buy one.

    Don’t worry. Vans say you can build an RV-12 in about 900 hrs. It took me nearly twice that but who cares!

    FWIW the RV-12 has 127 sq ft with a constant chord wing and MTOW 600 kg. Sling 2 also has 127 sq ft but with a tapered wing, although I'm sure you already know that as it's one of the aircraft you mentioned previously. Agree that retracts are not worth it in this class of aircraft. As has been mentioned, none of the RV's have them and they perform very well.

    Good idea carrying the rudder all the way down. Should help spin recovery.

    OK thanks. It’s quite an undertaking. Sounds like it might be an idea to have an experienced aeronautical engineer do a detailed design review and provide some technical guidance. It might save a lot of expensive prototype development and testing. Looking at the streamlined shape and weight, 120 kt cruise seems realistic as does 45 kt stall. The devil will be in the detail and effort required to turn a computer model into a functioning aircraft with all the fuel systems, flight controls, electrical and avionics components, engine installation, etc designed, documented and flight tested. Good luck with it.

    I'm not familiar with Fusion 360 other than reading Autodesk's description of what it can do. I know it can do stress analysis for example, but how are you determining the flight loads to feed into the stress analysis. Having the software work out stresses once you've entered the loads is one thing, but how are you then deciding what are acceptable stress/deflection limits etc. What about flutter analysis? What sort of performance do you expect the aircraft to have? I'm asking because I'm curious, not because I want to come across as critical. You've spent a lot of time and effort to get the external shape looking great, but I'm just wondering about the engineering design behind it.

    It looks very sleek but I'm curious as to how you are doing the structural and aerodynamic design and what materials you plan on using?

    My prop is a Sensenich ground adjustable and pitch is set while it’s on the plane. Your looks quite different but I’m sure someone here will know how to adjust it.
  10. rgmwa
    I don't know what prop or pitch adjustment method the Sportstar has, but on the RV-12 we're told to try to get the blades set to within 1/10 of a degree of each other. I use a digital level and bracket that clips onto the prop.

    Ocean Infinity must be fairly confident if they're prepared to roll the dice on a $70m fee. Hope they find it.

    Don, from what I understand North Dakota overall is pretty solidly pro-Trump. You obviously have a different opinion, as most of us here do. What's the general view of Trump in your neck of the woods?
  13. rgmwa
    Some of those number look a bit optimistic. 160kt cruise and Vne=220kts on 78 hp? 1,000nm range on 19 US gal? Service ceiling 28,800'?
  14. rgmwa
    There's always room for you and the project over here, Don.

    He'd make an exception for himself and waive the tariff.

    If you’re near an airport have a talk to the flight schools or FBO staff. They will be able to answer a lot of your questions.

    Round trip from where to where? More to the point, why buy a plane with all the associated hangar and maintenance costs when it would be cheaper and easier to hire a plane and pilot when you needed to. Also, this is primarily an Australian site and assume you are wanting to fly in the USA?

    He may have to settle for gold spray paint if he wants to go joyriding before he gets dumped from the White House.
  19. rgmwa
    Nice!
  20. rgmwa
    Impressive aircraft. Very sleek design and a top speed of over 400 kts is very fast for the time.
  21. rgmwa
    If they are pushing on with the RV-15 development I assume that's a sign they are on the road to financial recovery.
  22. rgmwa
    Can’t do any harm if your tiedowns are a bit dodgy.
  23. rgmwa
    One trick I've heard about but haven't tried is to lay thick rope along the wing to break up the airflow and the lift. Sounds plausible.

    Just came across this interesting old video. Not sure if it's the same as the one in the original post that has been removed.
  25. rgmwa
    Thanks. Didn't know about the re-registration. His last aircraft, a Dyn-Aero MCR-01VLA (VH-SIP) was unfortunately involved in a fatal accident at Serpentine in 2020 after a partial power loss.
