This feels like riding a normal bike. It's not fast, but surely it can be improved.
I say, the most efficient is : Pedal-powered Oars.
I find the assumption that pedals have to rotate a prop, decidedly unimaginative
Test in Water
I've tested in water :
With the 10" prop.
At 12V (1/4...
Shaft is hollow, will try two props
Yes the shaft is hollow 32mm diam, 3mm-wall Al-tube. (1 1/4inch)
mmm,so the prop has probably too much...
Speed 2000 rpm,
Yes, it is a water cooled motor so fairly splash proof.
I would like a closed water cooling system.. a small pump...
I am building an Electric inboard drive system and keeping a Blog.
I'm interested in advice as well sharing...
Regarding the 'design', what part will perform terribly ?
I have made a 4mm ply version of the concave punt and it planes beautifully at low...
My claim was an exaggeration.
And name calling is childish.
At high speed props become more efficient.
At low speed...
The hard research
My claims are based on this paper:...
90mm plumbers pipe, space material
Do not be deterred by the nay sayers my friend.
I intend to drive this thing all the way to hell and back...
The future for propulsion
Not only is an oscillating tail a neat idea, it is the future of propulsion.
Your best prop on the best engine is...
Higher voltage higher speed
Interesting post, regarding voltage, yes higher voltage means higher RPM
The current is max at stall and minimum...
A 2 Hp could pull a water skier.
Horse power and pounds of thrust
I don't like formulas and overly complicated answers.
Horse power and thrust are directly related....
