>>1341434Landing gear need to be so high because of lift/flex.
At speed and on takeoff, those things would probably have 3-5 feet of tip-up.
On landing they would flex the same down.
So, 7-10 feet of vertical change from a level position necessitates either:
A. Tall gear
or
B. Small gear on the wingtips.
Think, "B-52" here.
