INFINITE FLIGHT - MADE BETTER






Sleek, quiet, charming. This craft sets the standard for all the future ornithopters to come. This industry is rife with noisy pistons, or worse, fakes with hidden fuel guzzling engines. Here at Semedian Industries, we've gone beyond green, beyond electric. Powered by [REDACTED], we've broken the laws of thermodynamics repeatedly to provide you with the very best engineering the market can offer!






Our previous models, thought true to the principle of infinite flight, were heavy, unstable, sluggish, and noisy, but not the Silver Dragon. Take-off can be achieved and a few seconds, as opposed to the almost minute long roll from previous models. And yes, if it looks like a dragonfly, it must fly like one, and it does. Both horizontal and vertical flights are possible and easily interchangeable, just be sure to keep your hands on the controls when you do. Do you like speed and acrobatics? We gotchu, we were just as surprised as you probably are to find out how good of a racer this craft is. You prefer comfort instead? We gotchu too, it's capable of quite slow unpowered flight and comes equipped with a smooth and versatile autopilot. We've truly built a jack-of-all-trades, Werdon Defense Dynamics surely is interested in developing this technology further.

DOS and DO-NOTS

  • Fast Landings - You may tilt the wings down to induce some downforce if your landing speed is much higher than 80kts.
  • Vertical Take-off - Throttle above 80% while grounded seems to reverse the trust and slam the craft back down, so it's only safe to firewall it when the ground clearance dihedral has reduced enough.
  • Vertical Landing - When experiencing a loss of pitch authority, throttle back up and abort the landing. Reduce any horizontal velocity component you may carry and try again.

  • Transition to and from Hover Mode

    1. When grounded, keep the throttle cut while the transition happens, or else the wings will impact the ground
    2. While airborne, pitch gets snappy, so keep those hands ready for a sudden pitch down.

    Great, but how does this affect the ornithroper population?

    Oh wait...

    It increases it 🤯
