The rate of roll of the Zero is faster from right to left than from left to right.
An outstanding characteristic of the Zero is its high rate of "zoom." This "zoom" is at nearly a vertical angle and can be continued from fifteen hundred (1500) to two thousand (2,000) feet depending upon the starting speed. This should not be considered as indicative of the rate of climb of this airplane.
The Zero does no possess a particularly high rate of climb as indicated by the following performance figures.

* Critical altitude.
The Zero is very stable and has excellent stall characteristics.
There is no tendency for the wing to whip when a stall is reached.
A slight tail flutter was experienced at three hundred thirteen (313) miles per hour indicated. It has not been definitely determined if this is a weakness of the Zero type or of this one airplane.
Take-off is very rapid. The ship became airborne with little effort by the pilot.
The Zero lands from a gliding speed of eighty-five (85) miles per hour indicated; estimated landing speed fifty-five (55) miles per hour indicated. The ship is very easy to land with no tendency to ground loop.
