My carb heat is nearly identical to Mark's and is pretty much an 
industry standard.  Some designs close the shroud and run ram air to 
the shroud which is dumped when not used for carb  heat.

My cabin heat is similar but I do not recommend my exact setup.

https://dl.dropboxusercontent.com/u/32133949/IMG_8090.jpg

It should have a sealed shroud and have fresh ram air to the 
shroud.  My setup introduces the possibility of carbon monoxide 
entering the cabin if an exhaust leak should occur.  I'm comfortable 
with the setup for now for two reasons.  I use cabin heat very, very 
little and then only for short durations at very cold 
temperatures.  Second, my exhaust is all new stainless steel with new 
gaskets and I have a carbon monoxide detector patch on the 
panel.  But, like I said, I don't recommend this as the right way to 
do it. I use a small fan on the back side of the firewall to blow in 
hot air when I open the cabin heat door on the firewall.  I may break 
down this winter and close the shroud and add fresh ram air.  I flew 
for 6 or 7 years in temps down to 15 to 20 degrees F with no cabin 
heat at all.  KR fliers are a tough crowd but do it right to 
eliminate all possible concerns.

My thrust line is 2.5" below the tops of the longerons, and the plane 
behaves normally with changes in throttle setting.
See http://www.n56ml.com/corvair/mount_fit.html for more on that and 
engine mount construction.

Also, my carb heat / heater solution is shown at
http://www.n56ml.com/corvair/airbox/.

There's a lot of good information in the archives at
http://tugantek.com/archmailv2-kr/search.  If you'll visit there, and 
enter the word "thrust" in the "subject" field, you'll get a hundred 
messages previously sent to the list, most on the subject of thrust 
lines and locations.  Entering other key words will yield equally good 
results.  I'm not discouraging questions to the list, but you can get a 
LOT more replies and viewpoints in a matter of seconds, instead of 
waiting a few days to get one or two...

KR> Several Questions:

[Robert7721]

Trevor,


I've see several posts back to you on using conduit inside. That is probably 
the best solution. If you do try and do it on an exterior surface, use the 
bottom - no one will ever see the repair job.  Same for the wing walk - leave 
the top alone and add just a couple of more layers on top for the step - 
reinforce from the bottom and repair the fiberglass from that side as well. 


Not sure about your question on heating, but the Tony Bingelis books have a ton 
of hints on how to build your own shroud heater - his design is what I used. I 
highly recommend his books. He also has info on Panels, lighting, wiring, etc.

My strobe on top does not have any reinforcement added. 


Happy building!

Subject: KR> Several Questions:




So, I'm finally getting started on my airplane I bought while I
was
deployed. I conned a friend to help me by giving him the completed frame
of
my Super Koala (his father is one of those who wanted a low and
slow
aircraft). Tomorrow we are going to break ground on some of the projects
I
have before I start putting everything together.



I am going to be
cutting a thin line in the wing so I can lay electrical
cable to the position
lights and strobes at the tips of the wings. The
person I bought the aircraft
from didn't run any electrical through the
wings, so I'm thinking of using a
dermal to cut a narrow deep line so I can
lay the cord without having to dig
through the spar and what not. Then I
plan on filling in the hole with foam and
re-applying fiberglass.

It was suggested that instead of placing it on the
leading edge, that I
place the cut under the wing.

So, my question is which
is a better idea, the leading edge, where it will
then be
re-sealed/fiber-glassed or under the wing?

While on the subject of the wings,
anyone have experience with STOLSPEED
Vortex Generators for the wings that
they'd be willing to share their
performance experiences?



Also, I'm
adding a smaller LED beacon to the top of the airframe, and where
it's going to
sit is just a thin piece of fiberglass (about 2-3 feet behind
where the
turtle-deck would be. Generally speaking, should I reinforce that
area before I
install it, or leave it alone?



Third question, anyone have experience
with designing electrical systems,
and installing cabin heaters using a shroud
around the exhaust pipes?



Next, on the wing stubs, I will essentially
need to cut out the top
fiberglass on both sides in order to re-enforce the
areas where I'll be
walking on the wings so I can get in and out. What is the
best way of doing
this? Adding wood or extra layers of fiberglass?


Lastly,
anyone have suggestions on how to make the panel? I'm thinking
fiberglass or
aluminum. I am getting rid of the old panel in hopes I can
simplify the layout
so it's more user friendly. 



Thank you very much for your help in
advance.

There is no need to cut the wing to lay the wire. Go and get a piece of 1/2"

Treavor,
There is no need to cut the wing to lay the wire. Go and get a piece of 1/2" 
EMT conduit that is 10 feet long. On one end use your dremel tools to cut 
some teeth into the conduit. Essentially you are making a 10 foot long hole 
saw. Since you are cutting through foam, you can then, by hand, drill the 
hole lengthwise through the wing in the location you wish for your wires to 
run. Once you have the homemade 10 foot hole saw through the wing take a 
fish tape and push it through the EMT conduit to push out any foam which is 
now inside the conduit. Once that is done use the fishtape to pull your 
wires back through the conduit. You could leave the conduit in the wing as 
it is minimal weight or you can remove the conduit by securing the wires on 
one end and slowly pulling the conduit out of the wing slowly turning it as 
you do so.
Hope this helps.

[Mike Sylvester]

I agree with Dan, You could for example, use a long piece of conduit with hand 
notched teeth as a drill bit or even weld or J.B. Weld a real drill bit in the 
end of it.
