Motor has no power when in water

[MAMBA2200]

gfm i just looked these up and they do have a program card and it looks identical to a hobbywing or turnigy and the card looks the same also if you can find someone that has one near you i bet there card would work for you esc

Where did you find a program card for the Skywing?

[MAMBA2200]

i think it was leaderhobby.com not sure i googled it

[TheShaughnessy]

5000mah 40C(Haiyin) with 120a esc

Is that a 3 s lipo?
You should just be able to use the flow chart and your transmitter to set the LVC just so you don't have to wait on a programming card

Yes it is 3s. I have already used my transmitter to program. If the LVC is part of the programming for the number of cells, then that is done and LVC is not my issue.

[TheShaughnessy]

lvc is separate from cell count. Cell count options will be like. auto calculate, 2 cells, 3 cells, 4 cells, etc. LVC options will be like no protection. 2.8v, 3.0 v, 3.2v, 3.4 v or might just be none, low, med, high

Also that motor is almost better suited for 2s. what kind of boat is this in? might be ok in a rigger.

How old is the battery? I know its rated for 200 amp constant but that doesn't necessarily mean that it can put out that much. It may be sagging under load

What prop are you spinning? 3400x11.1= 37740 so pretty high rpm for sport usage.

There must not be a LVC on the Skywing. There are 6 options. # of cells, Throttle setting, rotation direction, timing, brake, PMW setting

is this your esc? looks like there isn't a LVC and it is set automatically based on the number of cells. You could try setting the cell count to 2 s to trick your esc, but then you would have to be very careful to not run your battery down too far. Its pretty much your only other option though.

Yes thats it. Would that cause lack of power when in the water. On the bench it seems fine.
