Go to Post The weight sounds about right, too. If you need more than 65 pounds for your manipulator, then the drivetrain isn't the part you should be redesigning... - s_forbes [more]

I think some epoxy and fiberglass cloth will be applied to this. Then maybe it gets hollowed out. Still don't have a clue what the result will be used for though.

Right on the money! After removing the foam, lots of sanding and painting, it looks pretty good. Now we just have to mount the motors and propellers, and viola! A shrouded propeller! According to a paper written by NACA (the predecessor to NASA) in 1958, it should increase thrust and efficiency by 50% to 75%

Now fitting these things on the bot and within the weight budget, that may be a challenge....
