ok guys, here's what i have. 6 1/2 lb rigger with feigao 8s with 4436kv,and 5000mah 5s batt., the cg will be at 40%, questions are, what esc should i use? should it be water cooled? what prop? do i need a silicon water jacket for the motor? what is a guess on mph? do i need to put the esc up front with the motor a nd batt.? thanks for putting up with me.

There is nothing that will work with that setup! no prop, esc nothing! you need to drop about 50,000 rpm!
Unless the 5s is a typo?
Did you mean 2s? That would put you right in the 30,000 rpm range which is ideal.

[iceman]

well, should i go less kv or less volts? i have no idea just want a fairly fast boat

[siberianhusky]

no 2s for that motor!

[iceman]

should i run 2s or go lower kv what would be better

[NativePaul]

A bigger motor with lower KV, 6.6lb is too much for that size motor or 2s to push. motor weight should be around 400g and around 1700kv.

what motor should i use and what batt. and prop

Can you please take a picture of it?
also the length of the hull would be nice.
