You've done a great job on them NZ S, they look terrific. Diesel fuel is almost impossible to buy here in Aust., I mix my own. Its hard to believe mine was built a year ago, still in one piece and flying well. They look like PAW engines. If you haven't flown C/L for a while you may get a case of the dizzies on 35' lines. They're pretty fast. Let us know how your test flights go....John
