    Glad you like radical posts - I just build aero stuff when time allows I just build, I'm not a "Mod" A lot of copies of this occurred, but this is the SP V1.0 build. @OldColonel

    @bobthetitan Thx! Originally this was a max speed challenge, and this deceptively simple design is very hard to out race in SP 1.1 or SP 1.2 -- built only with SP 1.1 parts.

    This thing is insane! We need a bigger world for it to fly around.

    Hi I hope you didn't mind of me reposting one of your planes and adding a few things to it I fell bad about it

    @PlanesAndThings This is the first true 30,000 mph model I've built. More to follow.

    @HeshamElSehmawy22 BTW it does 30,000 MPH at 3,000-4,000 (very low and difficult) but I sure had fun with one.
