Question

How do I go about cooling my Alfa FW-190?


Can I just cut some holes in the cowl or do I also need to cut a hole for the air to exit? How many holes should I cut and where and how big should I cut the exit hole? Also, is cutting holes in the cowling going to change how the plane flys?

I have the ALPHA Corsair . In addition to the 5-6 holes in the cowling you need to have an exit hole twice as large as the total cowling holes . What I did on my Corsair was to cut a hole in the arse end of the fuselage .

That's going to make for a big exit hole is it not?

Maybe I'll just stick to my 2 cell LiPo's.

You still need some cooling 2 cell or 3 cell lipos ...doesn't matter . On my corsair the hole is about 3/8 " across . I'm running the mp jet 25/25-20 with 2 cell 1500 mah lipos and it still gets plenty warm . Of course if you are in a more frigid clim than Florida you might be able to get away with less cooling .

Are the holes in the cowling going to throw off how the plane handles? I seems like all that air going in would change something.

Thanks for the help.

You need to cut a decent sized exit hole to give the hot air someplace to go. (Other than onto RCgroups.com, I mean.)

The only thing it does on my corsair is make a neat whistling
sound . As I recall the japs in wwII called the corsair "whistling Death "
