Here's the layout I came up with, thanks to the help from Snyke and others who decompiled the code and did the math.
Standing on top of the top generator, I read a height of 178. Since the generators can never exceed 6 EU/tick, they cannot melt the tin wire. The blades can thus never break, and I'm getting almost the best possible efficiency for a breakage-free height.
That's an MV transformer in the base there, raising the voltage to 512 EU/tick to send it to the MFSU on the ground.
