  • hey how did u rotate the rotors?? What mechanism did you use?

  • WOW !!!

  • Gary,
    horses for courses - the main use of a UAV is as an AP platform. Small areas and obliques - heli, large areas for mapping - fixed wing. If you are doing the latter do you really need a VTOL? - me thinks not. For me the UAV is a means to an end, not an end in itself - with that in mind a decent heli and an electric glider trump all - for now.

    but only once!

    For the amount of faff involved in big rotary projects I don't see the value over simple fixed wing platforms. For close in inspection, a tri or quad can get the job done pretty easily.

    Of course its all a function of how much you have to spend, I would love an RMAX.

    @Chris, if I point the nose down I can land in a very small space ;-)

    @Bart:
    "But if you want to take vertical aerial photo's, you can fly to each waypoint and hover to take a photo."
    For me this is not necessary.
    The wind is never null, in most cases you would need 5-20km/h forward speed to be stationary over ground.
    Hovering is only necessary for T/O+landing, as ground-level wind is smaller and the space is limited.

    @Mike helicopters use an awful lot of power to get the job done.
  • "No need to keep the fuselage horizontal for takeoff/landing if there are no humans aboard"
    But if you want to take vertical aerial photo's, you can fly to each waypoint and hover to take a photo. It all depends on the numbers. Does the model fly faster in airplane-mode than quad (ore other number) rotor thingy, Does it hover on a GPS point, How does it react/combine with a autopilot. Is it rigid enough? How fast does it drain the batteries. etc
    @Chris: sure but tickling the human senses is worth trying and this product does tickle mine for sure! ;-)
  • A fixed wing VTOL aircraft has better range, endurance, and speed than a helicopter, if you only need vertical takeoff/landing and limited hovering...
  • Isn't there something called a 'helicopter' that has those capabilities?
