I have put the battery as far back as the fuse that it allows right now to balance it per the plans, I can move it forward without too much trouble but will first tape on a little weight on the tips of the floats and see how it behaves. If it is successfull, then I will move the battery forward and remove the float tip weight to get the lightest airframe possible. Although I originaly was going to make this plane both land and sea, I think I will just keep this a float plane all the time. I have a fun 51 that fits the same flying type for land. Besides, the lake is less than half the distance as it is to the flying field so I just might do a lot more float flying in the future.
