Yep, 270cc (16 cubic inches) is very close to my original estimate of 15 cubic inches. The floats seem to provide about 13 cubic inches when half submerged, and that works obviously.
And to answer another poster, I DO plan to have a boat handy as I live on the waterfront.
270 is the absolute upper limit, that does not take into consideration the volume of the MM, which is not easy to estimate. The MM is about 13cm long, 6cm wide and 5cm tall, for a total of 390cc. Even assuming that only 1/4 of that is actual material, you have about 100cc of volume.
Long story short, I think 170cc might be enough to keep it afloat.
Having said that - and leaving the tone of some replies aside - I do agree that a float on an aircraft the size and power of the MM does not look like a good idea: it might prevent the AC from sinking, but it might cause it to crash in the water in the first place! |
