- accelerating the obselescence of IC.
- achieving the goal of no bias in exchange for 5.4 kg electrics (more expensive) vs 5.0 kg electrics (cheaper).


Here's another area where I completely disagree with your predictions.

A 5.4kg at take-off rule may accelerate the decline of IC. Only because it will bring the cost of electrics down to the point where it becomes more attractive to switch. Not because they will suddenly become uncompetitive. The rule change may in fact allow for the development of competitive gas engines in the event, as their fuel is lighter allowing more leeway in the empty weight. I do believe that with no changes, we will continue to see more electrics and fewer IC models in pattern. That is how the entire hobby is evolving. But with no changes the costs will rise.

Your basic statement of heavier electrics being more expensive is in my opinion flawed. There is nothing in pattern that is less expensive when it is made lighter. Just the opposite.
