Mitsubishi F1m Pete having good sound control?

[Fatboy Coxy]

Hi all, while researching the flight characteristics of the Mitsubishi F1M Pete, I came across the expression having good sound controlling.

'The wings were of a biplane arrangement which added drag but made for excellent lift qualities and sound controlling'

Can anyone explain what is meant by this please?

I would say it is a bit of mistranslation from another language (possibly Japanese) - so 'sound controlling' probably means 'good control' as in the 'controls were sound'.

My guess is it's referring to control harmony.
