Baffle, Oil Radiator Inlet, Yak 52
Don’t tolerate oil temperature needles in the low caution range when you fly - land and do something about it. Remember, however chilly you feel on the ground, what matters is the temperature of the colder air aloft, blasting across your Oil Radiator at 130 knots.
In combination with the radiator outlet door, this ground-adjustable Oil Radiator blanking plate will keep your Yak’s oil in the green in the coldest months of the South Western US winter.
Further East and into the Midwest, if your oil Temperature needle hasn’t moved into the green during the run up, you can shut down, remove the plate & flatten up to four of the flaps to block even more cold air from entering your Oil Radiator.
Just to get us all on the same page, this ground adjustable baffle plate is designed to be bent once - to find the sweet spot for your Winter conditions, rather than to be adjusted every flight.
How many times can you bend a flap before the material will crack?
And don’t forget to remove this baffle when warmer Springtime weather comes...
Made from 5052-T32 Aluminum, riveted and anodized. Three rubber buffers, screwed to the rear face, prevent damage to the face of the Oil Radiator core.
