You generally don't stir up thought by being rude. Wether you stated "not to sound rude" or anything, you still did.
For a C206 not to get airbourne in that length of strip, well the alarm bells are ringing.
The weight and balance of a 206 is simple.
Can you close the doors? Yes. Check, weight is ok.
When you push tail down, does it come back up? Yes. Check, Balance is fine.
40 degree heat on a sand runway and they will get airbourne and climb. (May have to raise the collective a bit to get airbourne)
But the are impressive doing a beat-up. They make a good noise. Purely for scaring the zebra and such off the runway though...
