SECOND: What setup could be used to do such a load test??
Is it mandatory to actual freefall drop or somehow just apply the load??


I vote for a drop, so it rings like a bell. A steady load won't be the same.


Untrue. Force is force. If you can calculate how much pressure is put on the
gear, by taking into account the weight of the craft, and the height at which it
is dropped, a steady load is the same. It could be even more stress on the
gear, because factors such as tire deflection will not be taken into account
with a steady force test, and it would actually decrease the amount of force put
on the gear in the drop test. Bear in mind that it will be a very sizable
load, though! g

I myself, would rather do the drop test. Less sandbags to fill and place, and
the drop would make a really good video, too! :-)
