I have had my staggerwing for about 2 years now but have a question about other peoples setup. I have a OS160FX and I had to add about 22oz(1.5lbs) of weight to the nose of the plane to balance. My weight come from 9 oz of lead, and 13oz 3600mah battery. That being said people using the OS160fx and the OS160 Gemini how much did you all have to add to the front to balance. Now I do not have the retracts so that is probably why I have to add so much weight to the front. Oh I do not have the dumy radial in it either so that would probably add a few oz if I did have it installed. I do not want to go gas and I know it would be cheaper if I did.
