| Subject: | Windshield install & defrost fans |
About ready to install windshield but realizing this would best time to plan for
install of defrost fans. Is 4" a standard size? Am I just needing a 4" diam
hole ? Or should it be more or less? Thinking about cutting holes now since
I haven't yet settled on cfm output yet nor acquired fans. Looking for dimension
placement relative to windshield--- as close as possible? 2" from ?

Attached photo is what I did. Works well. The hole pattern eliminated the
need for a screen.
I got a dozen or so 3", 0.12A, 12vdc brushless muffin fans from EBay for
perhaps $1 each. You want enough fan to move air, not create a tornado. A
single 2" fan worked well in the RV-8A.
Even with the fans off the heat from the avionics and cabin heat will come
up though the holes. I tend to use the fans more in summer to add
additional cooling for the avionics than in the winter for defrost - but on
the few occasions I needed to defrost these were more than adequate.

It really depends on your panel layout. Mine are about 4" off center. Since
I have an Aerosport panel, the right one is over the comm stack. You just
need to ensure clearance and have an understanding of the likely heat sources.
While the fans are fairly standardized, I would buy them now to ensure the proper
size.

What Bob said....
There really isn't a standard size, so it's best to find your fans and then drill
the holes to match. When I got my fans I bought a 3rd just to keep in a cabinet
for the day when one of the two in the airplane quit working.
I have two fans that are centered between the center rib and the side ribs. Using
the Aerosport panel, that put one over the radio stack and another behind
my PFD/MFD.

I bought two of these fans and grilles from Amazon (see below) and installed them
so that they are centered between the IP and sub panel and evenly spaced right
and left. They are wired to run continuously at the lowest speed. They come
with jumpers that you can use to insert between the plugs to reduce the speed
from 2000 rpm to 1600 or 1200. They are very quiet at all speeds.

Be careful here, you might run into problems like the Turbo Encabulator.
You have to worry about problems with Modial Interaction.
Here is a reference: https://www.youtube.com/watch?v=rLDgQg6bq7o
If Vans thought it was ok to have these fans, they would have put them in
the drawings and included cheap fans in the parts bag.
.........
I used two 80mm fans. Worked fine when needed for defrost, but as mentioned
by others, I use them more for airflow on hot days.

| Subject: | Re: Windshield install & defrost fans |
I have two suggestions.
1. Pretty obvious, but use a metal grill. A plastic one will melt.
2. A high quality fan will save effort because a cheap fan won't last long. First
one lasted about 10 hours. I then got a much higher quality ball bearing
one. A little noisier which I actually like because it tells me its on but
I can't hear it once the engine is running. I run mine continuously on an integrated
switch breaker and a resister to step the speed down so it lasts longer.
Second fan has 140 hours on it with zero issues.
Although I installed it solely for avionics cooling and defrost purposes, just
yesterday I spent over a half hour in IMC and for a brief period got speckles
of windshield ice most everywhere except above the fan. I would stop short of
calling it anti-ice, but it definitely keeps that part of the windshield warmer.
