leopard 4092 1480kv problem

[Boaterguy1000]

why does my leopard model boat motor 4092 1480kv run for a minute then shut down and starts again

For staters, how about sharing more info. Boat, batteries, prop, esc... and so forth.

Hi,

The boat is a Hobbyking osprey, running an octura m447 prop with seaking 180a esc set to 11.25 degrees, batteries are turnugy nano tech 5000mah 65 -130 with ec5 connectors, after a couple of minutes it cuts power as if the thermal cut off has cut in, it has seperate watercooling for esc and motor, thanks, the esc is brand new, we have also tried different batteries but still does the same

To start with, try changing the timing. That's a d wind so 0-5 degrees timing.
Check your driveline for any binding. Try a smaller prop yet? What's the lvc set to?

[Boaterguy1000]

the lvc is set at 3.0v

What cell count? Is your esc set to auto calculate?

[Boaterguy1000]

It is set to 6 cells, thanks, last week we used a hobbyking 120a esc and it still did the same, could the motor be shorting out inside, although the motor and esc are cool to the touch, thanks for the prompt replies, it is actually my brother kenneth's boat but he is no good on computer

try turning lvc down or off. I've had trouble in the past with setting lvc on those esc to 3.0

[Boaterguy1000]

if i turn it off will it not over discharge the batteries , thanks

Maybe someone else will think of something I have not. But, process of elimination

If you turn it off, just watch runtimes. 3 minutes on a fe boat is pretty norm. Otherwise just try turning it down to 2.8 or whatever the next lower setting is and try that

if this problem is still happening with different esc,s then you need to firstly try a smaller prop, make sure the shaft is not binding and there is a gap between the drive dog and strut [ 3/16 inch gap ] run the boat for 1 minute hard and see how things go. also make sure the bolts that go into the motor for mounting are not too long as there could be a chance that your getting some arcing which will cause heating in the motor.

I, this very minute am experiencing the same issue with a brand new leopard 4074 2000kv and a seaking 180
I just upgraded the motor and the flex shaft......leo was timed to Y
tried 2s in series, tried 4s in parallel, then 6s in series

the upgrade shaft is spinning smoother than the stock shaft with a liner so its not my installation causing friction

on 4 s I made a run and at top end which wasnt impressive & it cut out...then would run at say 1/2 speed or less
tried 6s with same results, turned off the low voltage in the seaking ESC same results

I swapped to a 120A turnigy same thing.....then I turned off the low voltage and now it runs fine but again not really impressed with the speed the stock SSS motor is faster...for the money this leo better last more then 30- 50 runs like the sss motor did if it is going to be a slower motor

Ill try some tuning but not impressed with this leo at all...oh and the offset rudder brkt mod is also a big disappointment.....untill you hit 30mph and get it running on the pad it drags in the water throwing a spray up 2ft in the air till it gets up on the pad at real speed

I was able to achive 58mph on 6s with a complete stock genesis I will install the gps to see how much slower this LEO motor is going again Ill try some tuning

dont know what to tell you? I suspect the motor

it just could be your batteries. Have you tried different batts?

[rol243]

theres realy not much to a brushless motor other than its windings / magnets and bearings so if the motor feels ok to turn by hand it should be ok, the esc is the main commander that works the brushless motor not like the older type brushed motors that mainly relied on battery power to supply rpms, this is why you can,t connect the brushless direct to a battery for power as opposed to a brushed that you can connect battery power and go. i would be trying this motor out with no shaft connected and hold 50% power on for a couple of minutes and see if the mount end of motor gets warm / hot plus any cut outs. as mentioned if you have longer than suitable bolts going into the motor face housing this could be causing an arc of current which will give all sorts of issues. i had this issue with an aero brushless motor where the bolt mountings were too long and just touching the internal windings, the motor was getting warm to hot very quick plus it was cutting out for no reason other than what i just mentioned. check the bolts to be sure.
