Considering how cheap 1.5kw or 2kw Outrunner Brushless have become, I dont see how Large and Electric are mutually exclusive anymore. Tower has a 1hp / 2hp Max 35x48mm outrunner for $40, or go geared 11x7e prop at continuous 11k with a $35 36x56 Inrunner (1kw/2kw Max).

Just what size P-38 or B25 would fit a pair of 2000watt (2.5hp+) outrunners? 80"? 100"? 120"?

Check the Aug07 MA cover for IMAA electric running just a pair of 750watt.... sounds like $80 for the similar pair from Tower, but with Burst of roughly twice the power.

Large and Electric are no longer mutually exclusive
Now If I can just get the 80" balsa twin frame down to 24oz for PPP IMAA
