[NSRCA-discussion] 12S for F3A

[Phil]

Rob, 

Your analysis is not just speculation, or a thought experiment. When SPA first allowed electric power, there was a "classic pattern" plane at a contest that sat on its landing gear at at least a 45-degree angle to accommodate the looonnnggg prop on the motor. We fixed that by limiting both the KV and prop length. Electric, under our current rules, is just as competitive as glow power, BTW.

This change will drive motor manufacturers to develop lower kV motors to effectively use the power. The lower kV motors will need larger props to take advantage of the higher torque. This will mean taller landing gear to accommodate the larger props. 

That's just a quick and dirty on the Ripple effect a change to 12S will cause.
