Phatbob02 - I had one of these as well and it is indeed a great flying model. I made no engine thrust modifications and had to use very little trim to get it to fly straight. With the inverted engine, either make the tank modification Spanky 910 talks about, or install a Perry Pump or Klien Regulator to keep the invereted engine from flooding. I did install an Irvine 53 in mine and it flew quiet well. It flew inverted quiet well as Spanky910 has indicated, and with the Irvine 53, would go vertical for a ways before finally falling out. I could go vertical and do an aileron roll, capping it off with a beautiful tailslide before falling off into a hammerhead turn. It was my second airplane (first after the trainer) and I lost it to signal loss - - - what a helpless feeling!!!

I would recommend carrying a little power, a couple of clicks of throttle only, and/or speed on base and final until you cross the fence then cut the power and flare, and it will land like it was on a string. Loved flying that airplane - In fact, I liked mine so much, I have one sitting here in a box ready to be put together. I just hope that when I finally put the new one together, it will fly as well as the first one.

Above all, remember that, "Experience is a hard teacher. She always gives the test first and the lesson sometime later!"
