    Tobias,

    Sweet! Please share your results.

    Because this blog mentions the tiger-8108 and the website doesn't give much info...I'm in contact with tiger sales and this is the best data I got until now:

    6S (20V); 9A; 180W; 2kg thrust/28" prop; $250,--; 30A ECS recommended

    I'll order a couple to test them (at least that's my plan); however, I'll go for smaller blade diameter but more 3-4 blades.

    I thnik "e-volo 200" *is not* supercritical design =)

    F1P further thought especially true of Quadcopters.

    For super critical systems any failure = total failure.

    "Weakest link in the chain".

    And, Robert, yes, recovery is NOT one of multicopters strong points.

    Although a good case could be made for an Octocopter with dual systems each capable of operating 4 opposed motors in quadcopter fashion allowing that ample power / thrust could be generated to at least control descent.

    Or a duodeca copter with 3 systems for that matter.

    Мы можем выполнить в середине. Удачи друг.

    the more the quantity of elements in system, the is less influence of an error of each of them

    ps. google translator is worst way for english-russian understanding.  i surrender  =)

    F1P,

    Я в шутку о статический баланс всех propellors

    Just thinking out loud - I wonder if more blades, broader blades, more pitch, lighter materials - anything to keep the diameter / inertia down might make a larger motor work??
  • F1P February 5, 2013 at 8:43am

    imho balance is better

    1. general gyroscopic stabilizing effect is similar to one large at the same lift.
    2. at the same time, the Coriolis force is very well compensated.
    3. reaction time small rotor system is lower than the large, their number is not important.
    4. high stability "supermultikopters" has long time ago been proven to work

    5. only negative factor is highest overal cost

    t.e. one of real hexadecacopters from rcgroup forum, good mentioned  =)
