Oh am I bummed. When I got to weight and balance I've learned that the airframe cannot handle the nose weight of this 10 oz. dummy engine. I have had to pull it out. I had all the batteries in the tail and it still was not enough. Now with the dummy engine out and the Saito FG-40 up front I still had to put the RX batteries in the tail under the stab and the Ignition battery is still at the back edge of the wing. This is a really nose heavy bird with a 40cc on it! Ready for flight now. We will see how it goes tomorrow. Leo
