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.

If there had been this much response for any of the questions we have had
about how to get a rotary to fly we would have complete FWF packages (with
drawings) for every type of plane we are trying to fly!!!
This country doesn't need a health care plan (especially not the one they
are ramming down our throats), it needs a T-Shirt!
What is wrong with making a T shirt out of Tracy's button?? Oh, Er, that is
right, we are not flying...or building...we are designing a shirt!!
Anybody got any ideas why my install will not cool?
It seems that there is something fundamentally gremlin about the electrical
problems Chris B has been having with his EC-2...What is up with that??
