    - You want to build 380 instead of 800
    - You want to pay $100 for canopy instead of $4
    - You are prone for marketing hype
    - You want to build heavy pig using heavy motor, ESC, lipos
    - You think boomstrikes were caused by lack of the piece of paper or tape:

    - You want to drive a "Ferrari" manufactured in Asia (Vietnam?)
    - You like Santa sleight skids

    Am I infidel?

      @Overspeed

      What bugs me is Goblin fanboys arrogancy and rudeness.

      By the way I created this thread. So who is poluting it?

      The speed measured when flying in a speed competition which is when the TDV crashed is the average of an upwind and a downwind run. The GPS calculates its speed by picking up the GPS signals and then calculating the distance traveled vs the time taken. Now if have studied general relativity you would know that time and lengths dilate in accelerating reference frames, changes in the gravitational field (altitude) and relative motion. This means that the calculations are based off of measurements that are distorted when compared to your own reference frame. Keep in mind acceleration can also be centripetal so performing a slight turn is enough to induce acceleration and relativistic effects when going fast enough. Also the GPS relies on signals being left behind by satellites, these signals can often be disturbed by cloud cover. Why do you think so many Phantoms fly away and why it takes so long to get GPS lock and even then there's lots of drift.

      Ok, TDV is handmade in Germany to ensure high tolerances and quality control. The TDR was no doubt designed with the help of FEA to optimise every single part.
      It depends on what you define as profit. The raw materials requires to build a heli will cost no more than $100 but then you need a CNC mill, lathe and a few other things which all cost money and a lot of it if you want high tolerances. Then there's the tools for the mill and lathe, with the use of high quality materials (ones with high yield strength and hardness) the tools will blunt much faster and a blunt tool will still work however the finish and tolerances will be degraded. So there's $100K at least in investment if you want a machine that can pump out a helicopter within a month because you can of course buy a $3000 CNC machine but it will take you a week to make a large part at a good tolerance. Then on top of that you need to pay skilled workers to operate the machines then more people to package the parts.

      So yes, if you consider the time it takes to design a good helicopter to be free, labour to be free and just tag off of a mate's CNC machine and lathe it does cone $80 to make a helicopter and the rest is profit.

      The clones can offer helis at such a cheap cost by doing many things.
      First of all they do not have to spend any money designing and developing a helicopter, there's a big part of the cost gone.
      They use softer metals so the tools blunt slower so they save heaps on that.
      Blunt tools continue to be used to further lower costs at the expense of finish and tolerance.
      The can drive the machine harder so they do fewer and faster passes to maximise the use of skilled workers of course at the expense finish, tolerance and quality in general.
      The list just goes on and on...

      Min, you're on some shaky ground with your comments about the GPS. You might want to re-read a few theories and applications. Once this little dust up settles I'd be happy to explain it further. Until then I'll be in the front row with popcorn & 3D glasses.
      Box on!
