Apologies for double post, won't let me edit the last
Ok! After lots of reading threads on here, and some other bits and pieces, I am slowly getting my head around this. For all intents and purposes I'm looking to get the a simliar, if not better performance to an
MFA 850 Torpedo from a brushless motor, because brushless motors are more efficent, which helps me out in wanting to make the batteries last longer for better performance.
I've think I'm after about an 800kv brushless for 12v, giving me the max of about 10k rpm of the torpedo. What I can't figure out is why the brushless motors I look at around the 40 Amp mark! What Amps would
this pull whilst doing 10k rpm pushing the Sea Queen through the water on say, the stock prop, which is a 65mm three bladed brass one.

On a side note Wesbourne Models reckon that
this motor is ideal for the sea queen, and frankly it looks like a monster and would last not much time at all on a lot of batteries. So WHY!? is this comparable to the Torpedo 850? I am totally lost on this front. Should I be looking to FILL this boat with Ni-Mh or Li-Po batteries to last an hour with all this new motor technology? [/rant]
I am fairly sure that with time and revision, motor technology has not gotten worse, so it MUST be that I am understanding this all wrong, please help!!
