The AK1-3 is a best in class 2 seat piston ship with features found only in larger helicopters.
The AK 1-3 power-plant is a 156 hp, fuel injected, Subaru EJ-25. It is liquid cooled and was chosen for it's reliabilty and excellent power to weight ratio.
It uses premium automotive (car) fuel.
The cabin of the helicopter accomodates two crew members comfortably. The width of the cabin at shoulder level is 1200 mm (vs. Robinson R.22 - 1055 mm).
No t-bar here!
"I rate the engineering design and build quality as outstanding.
It would be an injustice to compare this helicopter to existing crop of kit-helicopters. I would rate this craft between a R22 Beta II and the Schweitzer 269C in terms of its weight lifting capacity, performance and cabin size"
