OK so I did my testing.

The answer is that the DJI 450/550 arm does not bend significantly more with the stock landing leg completely removed. With a 2 kg weight hung from the motor plate you're talking about fractions of a millimetre ... less than I could measure accurately. So I'll certainly remove them from the front booms ... possibly the others too. Removing the leg saves 5.5 grams ... so that would be 33 grams in total on a 550.

Out of interest the black arms I have are about a gram heavier than the white ones, and subjectively seem a little stiffer. I used a white one for the test.
