You're right. It took 13.5oz to balance with no LG. Total wieght is about 10.5lbs. I'm using the OS.61 since I already have one NIB. Hope to fly it tomorrow as soon as I put something bright on the wings so I can see it in a white sky. Still looking for an inverted pitts so I don't have to cut out the cowling to such a large degree. Plan to test fly without a cowling so I can fine tune the motor easily. Hope it goes well...
