cooling system and upgrades

[Orv Neisingh]

Guys, I have found that this simple 18” transmission cooler from Amazon works very well, is in the cool outside air flow, and does not block coolant flow through the radiator. I have installed this on many ships with great results.

Here is the top end of the oil cooler. I leave the tail boom bottom inspection covers off so the openings produce negative pressure sucking out the hot air from the engine compartment allowing cool air to be sucked in through the lower body panel side vents and flow over the oil cooler fins.
