Swapped the empty tank and the reciever/battery pack around and that did the trick as far as balancing goes, plus the smoke tank is right on the CG so it won't make a difference if it is full or empty. Ran a couple tanks of fuel through the 91 last night does it ever sound awesome. This is my first 4 stroke and i have to tell you i think that is the end of the 2 strokes for me. Anyways here is a couple pics, i had the assembly engineer with me as well. She love planes i am going to get her a rubber band one to play with. IF it is calm tonight i will maiden it right now the wind is blowing pretty good. Going down to the lake today to open up the cabing i guess i had better get my beaver on floats ready to fly. Spring is officially here!! IT's about time!!!!!
