this is what i'm trying to clean up some more ... Basically i completely sealed off the bypass now, and cleaned up the ducting ... so all there is left are a few naca cooling inlets that could cause resistance (around 2" sq total area) , and only two protruding aileron push rods ... I think the venturi suction through the outer pipe should make up for any drag from the inlets ... 36lbs thrust will do for now ... however with slight mods, a 50lbs big block would fit [8D] .. maybe on the next one , hehe ..
