The race to the "bottom" for EZB is a much different thing than for 35cm
due mainly to rule differences in construction. The issues with EZB that
are difficult to overcome are due to constructions restrictions, you
need 3.5# wood for props as the rules require all balsa blades, you need
excellent strength sub 4# wood for motor sticks and tailbooms and or
wing spars due to no bracing. This is not as much an issue with 35cm.
You do not need to make 50 motor sticks and test to find the best 2 or
3. You just roll a tube for the motorstick and tailboom. No need to
finds super wing spar wood as you can simply brace a wing instead of
flying unbraced. Props can be built up so the use of sub 4# on the prop
is no longer that big of a deal. Plus 35cm has no chord restriction so
it allows experimentation/freedom with wing area/model size and final
flying weight. Weight limit with only span restriction will eventually
lead to longer fat chord models (like how F1M looks compared to how a
Limited Pennyplane looks at the same weight). Same thing happened with
nocal, the weight limit plus wingspan only limit equaled Hosler Fury
(long model with wide chord wing).
