RE: Weight Requirements
The fact of the matter is that the technology is moving towards more powerful batteries that actually weigh more. I actually believe that the current rules are stiffleing the development of electric models. As IC motors increase in power and fuel consumption increases the flyer fits a bigger fuel tank. Witness the increase in tank size when the DZ motors came along. We electric flyers don't have this luxury unless we can reduce our airframe weights.
The effect of this is a) limited flight times, fly the schedule and land - no practicing the figures you got wrong and b) eventually the IC models will outstrip us in the power department because we can't use the more powerful electric stuff coming along.
I love my electrics and won't go back but the rules need a tweak.
