I did all of those engines the Satio 180 1st, i thougth this is great excpet the cleaning that was required after those flights. This made me switch to the RCS 1.4; at 12 3/4 lbs the 1.4 just did not have what it took to do anything other than fly around like the plane was a Great Planes spacewalker. I could only get about 200-250 feet of verticle. So off came that set up and on with a OS-160; that is one powerful engine and very good gas mileage. I did this for quite sometime until i folded my wing on my Desert Aircraft 77WS funtana. I hated having the zdz 40 sitting around so i pulled the ultmate down and went to wrok putting that zdz in there with a can set up. I like that deal and the power is great its like flying it with the os 160 excpet with a 20 inch prop.
