The tundra tires and pine trees suggest your photos were taken in Alaska. Such highly modified light bush aircraft may enter an Alaska STOL bush aircraft contest, where they compete for shortest takeoffs and landings with much rivalry. The dual propellers at angles provide more thrust, (and maybe drag), the very soft and very large diameter tundra tires absorb landing energy and other features such as extra large flaps, wing slats, Micro vortex generators and even landing on the back side of the power curve routinely win the event. The cold density altitude works, too. Some of these mods would put such aircraft in the Experimental and or Restricted class in America, but the Micro Development VGs have approved STCs for many aircraft.
I have watched the contests, which almost defy reality, or physics!
