which novak brushless system
 

I wan to get a hobbico pro fisherman outboard boat, but which novak system shold i get for it? If the motor gets a little wet is it going to be ruined? Should i use a mamba max system?

I would get an Mtroniks controller, because they are waterproof, and I would put it with a Feigao 380c motor. Getting the motor a little wet shouldn't ruin it, as long as you dry it off so that it doesn't rust.

The novak brushless motors are sensored. They are more sensitive to water than the sensorless motors. If you look at the back of the motor there is a circut board and this can be shorted out by water just like any other board. For a boat Id go with a sensorless setup.

I want something simple, and ican get as a package, because i hated the last brushless system i had. and i only want to run 6 cells

The mamba maxx is sensorless.

If you plan on running 6 cells only all the time, go w/ the 7700.

Wouldn't that be a little too high rpm at 55,000? I would say the 5700 would be a better choice, and would allow a little higher gearing (because of the increased torque) if top speed wasn't enough. Just my $0.02...

I have to assume that CastleCreations can do that math as well. The motor system is specified for a minumum of 6 cells so I would expect that it would run with no issuse at its lowest rated cell count.

Either will work, its just a matter of how you want to st up your system.

If it were mine personally I would probably go for the lower kv setup myself just so I could have some flexibility with the cell counts that I run. But, he stated that he will run 6 cell only so in that case I would just go with the highest kv. Hes just looking for plug it in and run it. No tweeking.<!-- sig -->

Well, in a boat, you have to factor in water resistance and the prop and stuff.

If you are running a small prop, you want more RPM, but if you have too much RPM on a small prop, then it sucks air and you lose power because its moving too much in a small area.

If you are running a large prop, you want a little less RPM, but too little causes slow top speed.

So, you want to find the perfect balance between a prop and motor.

Also, if you want top speed, you want a motor with more KV. They generally have more top end for higher top speed. You could gear up a low KV motor, but that usually results in less acceleration than a low KV motor geared properly for the same top speed. Then again, a high KV motor has less run time, because its more powerful.

So, my suggestion is run a medium sized prop and get a medium KV motor, thats probably the best setup, as a prop spinning at high RPM gives better top speed than a large prop at lower RPM.
