Sry but i dont see any conection with these both raports.

First raport is about Spitifire, Hurrciane, P36 and P40 - with not detail about types and no detail about type of airleons - if it was fabric or metal ones.

Second raport is clearly about Spitfire MVA with metal ailerons - but as i said i dont see conection between both raports.

Very poor roll rates of Spitfire from first raport suggest that it was with fabric covered ailerons. These confirm second roll rate chart which i posted with Spitfire MK V with metal airleons where roll rate is clearly improved over fabric covered ( from first test).

I got also another roll rate chart where roll rate of Spitfire MK V with metal airleons is about 100 deg/sec.
