...I am thinking 2 of Ben's new 5660 TP motors in 780kv on 16s with 2 of his 16s200a speedy's....
That is really too much voltage for a 780 Kv motor except for SAW running and is well over the manufacturer's recommended maximum rpm; 12S would be a better maximum. And it is never a good idea to run any ESC at its maximum voltage rating. Of course, if speed is more important than reliability.....

, I can't believe the low-brow motors you guys want to use in this big hull. Why not spend a few dollars and make it nice?
So you think the scorpions from MHZ are low brow motors? They have put much larger boats with less cells to very respectable speeds. And the price of these motors isn't what most would consider low brow!

For such a large boat, yes I do but that's just me. I have trouble believing the specs that MHZ publishes. Scorpion rates 5535s as relatively low amperage motors which saturate their windings above ~120 amps, converting additional power into heat. They are very rpm limited compared to inrunners, 22,000 rpm according to Scorpion. For $440 each you have other proven options. Don't get me wrong, I have Scorpion motors and love them for what they are, but for a five-foot-long scale boat I'd go with something I could get more serious performance out of.
At least they sound like turbines.....

I am only interested in SAW passes, I have other boats for long run times and good handling, besides which to make packs compatible between all my projects it would be 15s regardless, as I'll be using multiples of 3s packs. As far as running the esc to it's maximum, Ben has 24s versions on the way (and I have 4 on order) but they are rated to be USED at 16s, not maxed out.
Thank you for the sound advise tho fluid, despite being a new comer to these forums and rc boating, I build and shoot 2000+Hp turbocharged and fuel injected drag cars down a drag strip, so am not clueless to the mechanical limitations of any components and combinations and have a multitude of eagle tree data logging equipment and enough common sense to use it:D
