Default RE: Scratch built push tug

props and shafts are in


mock up but they look small so i'll leave room for 60mm props or maybe 5 blades,what do you think





I can see know where I went wrong on alot of the hull but this is my first and I know the next will be better...and smaller.
do you think the 50 mm's are too small,I hooked them up to a dremel and at 10000 rpm freeload turned into about 5000 in water,one prop pushed a great bit of thrust.I based my prop size off of my Bristol Bay with a 3 blade 50mm,direct drive 550 50 turn it pushes alot of propwash so I figured two 50mm's shoudl do it
