Japanese reports on new Soviet weapons in 1939?

The Nomonhan / Khalkin Gol "Incident" (practically undeclared war) saw Soviets using some of new planes and weapons in air combat.

To my knowledge it was during the air combats of Khalkin Gol when the first "air-to-air" missile or better said its direct predecessor unguided air-to-air rocket was tested. This RS-82 rocket was a success according to Soviet sources, but how did Japanese note this new weapon and did they confirm some of their losses being due to the use of RS-82 rockets?

As far as I know, the new biplane fighter I-153 was tested in Khalkin Gol. Again according to some Soviet sources it was an successfull experiment. According to Soviet sources I-153 pilots used successfully a decoy tactic letting their undercarriages be down like they were I-15 bis, which Japanese knew to be clearly inferior to their Ki-27. Before the combat I-153´s retracted their undercarriage thus and gained speed for the incoming combat, which turned to be successfull for Soviets as overconfident Japanese had been waiting to have relatively easy fight against inferior I-15 bis.

However in some Soviet comments it has been said that Khalkin Gol experience still showed that the manouverability of even most advanced biplane (I-153) could not match the speed of monoplane (Ki-27). Has anyone knowlegde which might have been the real results between Soviet I-153´s and Japanese Ki-27´s - and did Japanese make a report or some evaluation of new biplane fighter I-153?
