Hello, this is busa01.
About the roll rate of A6M3
In Japan, there is no data of the roll rate of A6M.
Then, I submit a pilot's testimony and quotation of reports.
---------------------------------------------------------------------------------------------
According to the handling manual of Zero Mk2 mod.3
When high-speed, the stick force of Mk2 fighter is very light.
(When it compares with Mk1 figter) .
It is necessary to move the control stick of Mk1 fighter with both hands in the case of ACM.
And we have to move it with all one's force.
However, the stick force of Mk2 fighter is very light, and easy handling.
* Mk2 fighter is Model 32, Mk1 fighter is Model 21 early model not had aileron balancing tab.
* Later model of A6M2b Model 21(Nakajima Avi mass-produced) had aileron balancing tab.
---------------------------------------------------------------------------------------------
And Mk2 fighter also has report that the roll is light and it is very advantageous in ACM.
(When it compares with Mk1 figter) .
---------------------------------------------------------------------------------------------
WO Ohara Ryouji of the test pilot of Yokosuka NFG has said like this.
The roll performance of model 32 is better than model 52.
Because, the area of aileron of model 52 is smaller than model 32.
Therefore, model 52 has small aileron effect.
The model 32 had most excellent maneuverability.

Incidentally I am not testing A6M3 in AH in detail.
Therefore, nothing can be said yet about the performance in AH.
Thank you for reading my poor English.
