Add an outlet for better drill

Might want to check the rpm of the cordless drill and see if it is enough. Otherwise, move up to a high rpm drill, 110v and just put one of these outlets in the hull. Should be enough room. The Wattgate 381 is a truly incredible outlet that has the potential to radically change the FE world. My 1700SCR-Nicads now hold 3800Mahr at 2.4v/cell after using this outlet with my charger.

Read up on it and be amazed!

That is amazing!
I think i am going to start storing the static electricity between the hull and the water to really get the boat going. Then i'll use what is left in a DC-DC buck converter with an interleaved inductor to decrease core saturation to bring down the voltage and power my house!


But anyway cordless drills are usually between 1200 and 1900 rpm at the chuck and if he used a 70mm guapner prop that would be a 6mph at the prop if it was above 1600rpm.
You don't need to use the chuck or the gearbox. It is just an idea.

Why the extra electronics? Just get two and plug one phase of the 220 into each and power the whole house. Or are the extra components there so you can sell the "extra electricity" back to the power company?

The only reason I questioned the rpm is he said a 35mm prop which I missed for the whole first part of the conversation. But yeah, playing with the gearing would work also. Guess I missed it again, huh?

I'm guessing it will be around a 35mm prop, its only going to be used for when the wind dies and I don't want a lot of drag from the prop. It might even be smaller.

Nice winter project DOBY!!!
Will we see it at the pond season 2011?
Other one I never had a chance to see it.... On the water that is....

I have held one of those a few weeks ago,,,,its a brick!

Just a tad to heavy

[LiPo Power]

My motor comes with motor mount, flex shaft ant trust bearings...

[BondoBrushless]

Q; could a drive even be attached to that huge shaft to be used if one wanted to ?

[785boats]

I run this combo on 2s with a 32mm 3 blade prop with more than enough speed in a long slender hull. Not as big as yours though But it should work for you.

More than enough power & no water cooling required for your application. I don't have any on mine & it's running all the time.
Cheers.

The first thing that popped in my head when you said low drag was a jet drive, think that would work?

I always wanted to try a sailboat!

[ozzie-crawl]

why not use a ep-1 out board,make it kick down only when its needed
i would think even a 35mm prop would create unwanted drag

[Rumdog]

Why not just use a good ol' brushed motor? You dont need speed, you're turning a small prop, at low rpm.

Old drill motors are cheep if you already have them! and you can make brushed esc's a lot easier than brushless ones.
