minimize the elevator gaps and steps to get the speed and efficiency. pull it up close. 51 inches, top and bottom 4 x 51 = 204 inches of gap. close it up. fuel at $6.70 per gallon, what have you got to lose?
and when you are ready to clean the elevator leading edge.... put a micro cloth thru the hinge and pull it thru.
also, 100K lumens in the back makes the prop look nice, and that 100K lumens is at the far back of the hangar!
