I know we can foil with less power,.thanks for posting details.
He goes about 30kmh at human power, but i wonder what speeds we will get with 11kw. A foil that can go 60 kmh is much more fun than 30kmh.
I also wonder how much watt we loose from the drag of the casing of the motor. Lets say 40kmh with 10cm diameter but with a sharp edgde
Have you ever had a bad fall waterskiing? I have and you can have a serious impact. Falling at 60kmh from a height of 1m above the sea will hurt like a mother $&*%$£!!
I think the most frustrating part of this project for me is by far trying to find gearboxes. I'd love to experiment with a complete budget build, but gearboxes seem pretty scarce in the UK (and very costly). I am debating whether an adjustable drill gearbox would work...
I will gladly eat it for breakfast lunch and dinner once I have one of these :lol:
I was just gonna strap this to a foil (with duct tape, of course):
Price :256 usd
Rated Speed: 1950 turns/minutes
Propeller:3 leaves/10.6 inch
Max speed:2500 meter/hour
Max power to propel:1000 KG
Suitable for:6-8 person
double the voltage to 48v/48a...
the spec says 25kph for 6-8 people... @ 24v/48a! 10.6" 3 blade propeller @ 1950rpm (under load??)
- YEAH RIGHT
... it is 86lb thrust though... I see a lot rated at 22kph for 500lb... so... maybe if I overvolt it, strap it to a foil, and sink a 72v test battery into the marine hatch I'll slap in (gotta get the best hatch sourced, important for this IMO)... that's what I was thinking for concept....
The motor is $250... the battery would be laying around... I will use a cheapo digital waterproof remote temp sensor temporarily... I am just trying to left myself up to motivate myself to sink (poor choice of words?) the rest ..... as an alternative if I am too lazy to pull a 'meister' (who is killing it, by the way):
- I print a 3D adaptor to attach the trolling motor directly
- water cool or swap out motor (depending on temps, I'm sure I will have to)
- custom ESC/waterproof remote
but I was so gung ho, like I said, I was just going to strap it to as is! ha
Oh, tell me I am not the only one who was thinking of mounting this into a upside down jet drive on the bottom fin to increase lift! hahahaha. Better get that angle right :lol:
