Roger, Thats just it, my first were stock setup so I am now familiar with what to expect. Get out and fly, the planes characteristics are mesmerising to the point that you may well be low on fuel by the time you realize that you have to bring it in. On doing some landings right off with a full load of fuel its very sweet, but just so your not wondering as to why it may not handle on aproach as it did earlier with a full tank. Let me specify that there is not a difference so great that it won't land just as easily when empty but keyed to this knowledge you may now pick up on it. It was much more evident once my CG was beyond 5 1/2" On landings, this plane makes any pilot look good. Joe

P.S. 2 strokes put out more pressure than 4 strokes, but still not enough pressure to push fuel from a tank at a greater distance. If this were not the case, all planes would come with the tank on the CG right from the manufacturer.
