CCRC1 - I've had several people tell me they use anti-freeze to clean their engines with good success. I've never tried it personally. You mention that it takes several hours to clean the engines though.
I started using the method I put on my site (see my last post) because it is what Clarence Lee recommends. It works wonders and only takes a few minutes. The worst part I ever cleaned was the muffler from my Raptor that gets castor cooked all over it in just a few flights. It takes about 5 minutes to come clean. Most engines come clean in under a minute. Give it a try sometime.
