First run with new motor/esc

[Mulisha]

Ok I might have to then I wouldn't have thought that prop would be to big for a 4074 motor at 1650kv

Hello,
Is your boat running wet ?
And is the flex shaft running nice and free ?

[Mulisha]

No it get's up, sits up on plane fine. Runs around 95km/h will have to start a youtube acc so i can upload some vids. Shaft is fine, i have it set to 4 deg but have had people say it's d and y wind :S

Ok,
What cells are you using and what connectors ?
Have any pictures of the boat and the setup that you can post ?
Also what was the temperature of the water where you were running at ?
Do you live in Brazil ? Br stands for.

6s ec5 for batteries bullets everywhere else. Br is brisbane australia wasnt much else way to abbreviate it. getting into winter so water is cool now

What kind of 6s cells do you have, C , Mah , Brand.
I would try shorting the wires on the motor to esc,
There are to many connectors and to much wire to.
Also go with the 5.5 on the cells to and get rid of the series wire.
I think that may help a lot for the whole setup all around.
Also in the pictures where the straps are,
I would move the cells back toward the transom to the next set of velcro pads.
Than if it air out to much lower the trim tabs some,
Or the strut setting to level and tabs up 3.5mm from bottom of hull.

They 5000 mah 45c turnigy nano tech. Can't shorten the wires that was the only place to put the motor and esc so i had to lengthen them as it was which i didnt want to do. I didnt know to go with bullets on the cells till a member said last week and I had already soldered everything on

Take a picture of the rear of the transom and hardware at prop eye level please.

You just need to move the esc 1 or 2 inches and it will work a lot better,
Just use a velcro strap to hold it in place,
Than when you need to grease the flex shaft and get to the coupler it can be moved easily to the side.

the spartan has the removable tray and if i move the ESC foward i have to lift it up off the floor of the tray and that will change my CG and i want the weight as low as possible in the hull

[lenny]

From looking at all the pictures now,
I think the whole setup is fighting it self to run on plane.
Hardware was that is and cell placement to,
And you should fix the wires and connector to.
I would set the strut level and the tabs to,
Than move the cell back to the next set of pads.
And test how it runs like that,
Than change one thing at a time if you have to.
I would need to see how it running first, Than make the change.

[Mulisha]

It's not the whole set up running hot just the motor that's why I thought timing esc and batteries are cool after 5-7 min runs

Ok good luck with it.
