The moderator's warm introduction of Peter to the group will resonate with all of us here. Peter's...

    Counterfeit Parts Warning

    This company is doing this very thing for records & material trace. No professional affiliation with the company; former professional affiliation with one of the principals (from the transport aircraft STC & PMA kits world). Interesting work they've done, gaining traction and adoption...

    Building a Wag-A-Bond

    57Marty, I have a set plans for the OG Sportsman 2+2 (not that plastic thing 😆). Got to check out the original plane at Wag Aero's place in WI one year on the way home from Air Venture and chat with Dick about it, circa mid 90's. I asked Dick about builders groups and newsletters, he said guys...

    The Great FreeCAD Thread

    Consider reviewing this YouTube channel for FreeCAD content: https://youtube.com/@JokoEngineeringhelp. He seems to be an experienced user of several CAD platforms and provides tips to head off problems. Other interesting content as well. No affiliation, just a fan of the channel.

    My 13B engine configuration (tentative)

    Did the seller say why they decided to remove the rotaries? Was it due to issues with their operation, or integration with the airframe? Thanks, John

    BD-4 Complete Airframe Project $3500 Las Vegas

    I posted a link to this notice over on BD-4.org Forum. A gentleman from Europe is asking for an email address of the seller. Can that be provided? I can pass it along. Not seeing how to private message on this site. The BD-4 site has a private message feature.... John

    10/23 Raptor Video

    Meaning, it had not been inspected by a representative of the FAA administrator (i.e. a DAR or FSDO ASI)? Not sure what (if any) the rules are for Russian registered experimental a/c in the US.

    Mazda 13b w/ Tracy Redrive

    Curious, how much horsepower do you estimate you're getting now, and much do you prefer to have? Is your current horsepower limited by some aspect of the installation (coolant or oil temps)? Thanks, John

    10/23 Raptor Video

    Thanks for the reply Marc. I thought the VNE/0.9 was a prescribed minimum relationship to Vd, enacted to prevent manufacturers from setting an arbitrarily low Vd. I've not read it as the required absolute relationship. I get it's probably a valid assumption to use for our purposes with E/AB.

    Does Van's publish their Vd value? For that tested to Vd, how did you obtain the value? Thanks, John

    @rotax618, nice looking rig! Did u build from a kit, one-off design? Happen to have a write up on the machine somewhere we could read about? I have interest in a combo CNC / laser cutter. John

    The 'daydreamers' thread...post your craziest designs and concepts here

    Well as long as we're daydreaming.... how about a flying replica of the SA-43 Hammerhead from the mid-90's TV show "Space: Above and Beyond"? Couple of Wankel 3-rotor rotary's driving ducted fans.... with afterburners. Fun!

    Leveling a Wag Aero Sportsman 2+2

    Hi Jamie, I have a plans set from Wag Aero for the 2+2 (purchased back in the early 90s I think). Leveling instructions are found on the back of sheet 17.00 under the instructions for "Rigging The Sportsman 2+2". "Laterally: Using a level 30 inches long, place it across the center of tube US-1...
