All these arguments about costs, length of sequence, etc., are just "Red Herrings".  They are attempts to deal with a fundamental inequity in the rules.  Electrics are weighed with batteries, and IC are weighed without fuel.  This is all just political nonsense stemming from some trying to protect IC power.  Make whatever weight limit you want, just make it equal by requiring that whatever power you choose, enough fuel is on board to complete the flight.  The rest of these arguments, and rule change proposals become unnecessary.  Jeez guys.....
