Rotax 912 side-effect while chasing radio problem

[RFguy]

just a footnote...I'd avoid tape, stuff tends to stick to adhesive post. but yeah a cover of sorts.

Skippy, the traditional fix here seems to be tape across the face of the radiator...though I did see a S Island build recently where they looked to be incorporating the oil cooling into the coolant circuit with some sort of plate heat exchanger, so requiring only one radiator.

 

My preference (at this stage) would be for a ground-adjustable blind on the radiator that I can set without lifting the cowl. The trick would be coming up with something secure, durable and rattle-free. I haven't given the design much thought at this stage............

I remember radiator blinds (both the shutter/louver type and the rollup/down type) on the cars & trucks of my youth - they certainly work and can be quite simple in operation. I think some Russian aircraft also had them fitted.

 

Remember - controlling exit air can be the most effective way of reducing/increasing cooling efficiency.
