It can be done, but it is a pain. Hard to get installed neatly.

| Subject: | Re: Heater Control Cables |
Bob,
Regarding the Heater Control Cables, I just finished installing them this past
weekend. Engine was installed with Mags in place. So, it can be done but it
will take a bit extra time as you work your way around everything (hoses, wires,
etc,) that is already in place. That said Id conclude: If you know where
your cables will be located on or around your panel and can install them go ahead
as it will be much easier with no engine in place - like 30 minutes including
cutting the cables to length as opposed to 2 hours with engine in place.
The problem is that unless you are building a sub panel for the cables that will
be attached to your instrument panel, AND will be attached from behind (meaning
forward or closer to the firewall) or under the instrument panel, you
very well may need to remove the control cables until final installation of your
instrument panel. That may be after your engine is in, so you are still struggling
with the tight quarters for cable installation, but, they would already
be cut to size etc. Study how the cable is attached at the knob end and you
will see what I mean.
If I were doing it again, Id still wait and do it one time, final, after panel
and engine is all in. The extra time you save trying to do it in advance can
be easily sucked up as you sit there stewing over where, what length, am I sure,
what if, Im not sure, I might not be able to, this could change, etc
Regarding your next question of oil cooler air control: I have heard enough comments
from flying RV-10 drivers that the temperature seems to hang around the
high 150s to low 160s in winter flight, that I added a cockpit controlled airflow
door on mine. My RV-6 had the same issue and I just fabricated a flow restrictor
for winter flight that I manually installed each winter. It worked
just fine bringing the temp back up to a nicely desired 180 degrees. The question
every year and as the seasons changed remained: what about that 3 hour flight
where you took off ambient 50 - 60 degrees then found yourself flying along
at altitude looking down at 0 degrees F, only to look over at the Oil Temp
and see 158 - 160 degrees = cringe:( Wish I had put in the restrictor! On
the 10, I want to be able to adjust that in flight!
Avery Tools has the air control door and TCW has the electronic controller if you
want to go that way too.
Hope that helps,
Rich Hansen - still finalizing, but end in sight

Knowing that it was possible but more of a pain once the engine is hung,
I came up with a mounting that was independent of the panel and pretty
much independent of cable length. It has worked well.
Heater cable mount on tunnel cover
<http://www.mykitlog.com/users/display_log.php?user=MauleDriver&project=224&category=2223&log=62927&row=3>
It detaches easily with one screw and can easily be kept out of the way
for all the panel and cockpit work as well as for maintenance once flying.
