Nah, as soon as you unweight the front wheels the load in the front shaft will drop to near enough zero, or at least, not very much, whilst at the same time you are loading the rear axle and the prop (and twisting it) its this twisting and untwisting that generates the heat. (much simplified, obv.). So unless you brake and accelerate to exactly the same amount, one prop will always get hotter than the other. The fact that its spinning at the same rate doesn't actually mean its doing the same work. Just that its spinning at the same speed.

Wonder how the DESC410 shafts behave with the extra diff in the system.

Would be interesting (but very dull) to pop some strain gauges onto front and rear props to see what the loads actually are........
