Hey,
I wonder if a pusher airplane will able to carry more weight compare to a pull airplane( conventional airplane). Just a thought I had and waiting to know.
Nah. From what I've read, pushers use more power to do the same thing. I don't know why.
I wanted to mention that you handled my initial outburst like a pro, though. I misunderstood what I was seeing and reading and you managed to push me aside with respect. That was very well done.
My next idea was helium bladders. Nope. I read the pdf. dang.
Keep in mind, my knowledge of aerodynamics is from my own schooling, and that was a long time ago. I get confused with RC because of what the power to weight ratio is capable of and the fact that my aerodynamics knowledge is so very basic.
You need lots of lift. Lifting surfaces cause drag, and that drag means you need more power. You were looking to the gearbox to get that extra thrust. OK.
Ratio. Back in my motorcycling days, I swapped out the rear sprocket for one with one more tooth. That little change meant I had less torque, but I pulled fewer RPM's at speed, got better gas mileage (I commuted on the thing, it was important) and generally stressed the drive train less.
I can kind of see it, but not quite. Does that give anyone any ideas?
