Hi Mike,
I went back thru your posts and found a couple of pics of your "homemade"
cowl...WOW! What an excellent job!  I really like the elimination of the
"Chipmunk with his cheeks full of nuts" look that the RV4 has..(Sorry guys
:>) )
I didn't find any pics of the innerds of your install...Do you have any?
What is the size of your inlet?  Outlet?  I suppose the top section is for
induction?

I also noticed that you had problems similar to Chris with the EC-2 getting
scrambled.

On the other hand, if it takes this much input to build a T shirt, its
amazing that anyone here has managed to build and fly anything. I hope we
can stop talking about T shirts soon.

Sorry to say Bill that I dont know what your cooling system looks like so
cant answer that question. Cooling was something I worried a lot about
because when I started my install it seems that everyone had cooling
problems. To date I've had zero problems with cooling (admittedly with
limited flight time to date but I hope to change that soon). My system has
generous inlets and outlets ( I think many people tend to undersize these
thinking that liquid cooling is more efficient so the holes dont need to be
as big). My thinking was its easier to start with a hole thats too big and
shrink it later than to enlarge something thats too small. I also used a
radiator with quite a lot of surface area compared with its thickness.
Easier  to get air to go through. Finally, with an RV and the big fan in the
front, my inlet gets plenty of prop blast right below the prop. Not sure
what type of airframe you have, but I admire the guys who have successful
cooling systems on pushers. I think trying to make a P51 style belly scoop
work is just looking for cooling problems, just my opinion. I havent yet
heard of a belly scoop on a puller auto conversion that actually worked.

On the EC2, I have some recent experience there. In my opinion the EC2
installation is a challenging proposition for someone without some
experience with electronics. I've worked as an electronics tech for 35 years
and still had some problems. In hindsight it appears that my problems were
caused by a not fully seated socketted chip rather than an installation
issue. Having said that, I did make some tweaks to my installation in trying
to resolve my problems, which I believe improved the system. It is clear
that the EC2 works if installed correctly, but pay close attention to proper
installation techniques. The installation instructions and the recent
comments on the forum in regards to proper installation arent suggestions,
they are mandatory if you want the EC2 to work.
