Title: Yak-2/4 radiators
Post by: warhawk on September 03, 2011, 09:10:19 PM
If the radiator was moved to the front of the engines of the Yak-4, why were the inlets on the back side of the engines retained? Also, were there radiator covers on the very end of the Yak-4 nacelles that could be opened (Like on Yak-2)?

Hi,
the front cooler of the Yak-4 is for oil only, its installation on that position replaced some small intakes on the engine sides of the Yak-2.
The back radiator is for water, and it is almost unchanged between Yak-2 and 4.

Massimo

Thanks for the clarification.

I have just recently begun to have interest in this machine, so I'm doing my research so I could make up my mind whether to buy Amodel's Yak-2 or Yak-4 (don't wanna buy both, since it's Amodel after all...)
