That's pretty much the best ESC you can get for that current rating. Boat looks good. ESC can only deliver what the batts can give and the motor can take though. You should pick your motor and bats first. Then get the ESC that can handle the combo.

HI and thank for relply will do m8 i new to the Electric boat i alway run gas but no where to run them now on LI NY .So Electric here i come

Read the sticky that ryan put together at the top. I will answer alot of questions and direct you which specifics to ask. The popular steup that alot of people seem to be arriving at lately is brushless 540 size 8XL motor on 4s with the ESC that you had mentioned. Another setup you may consider is the UL-1 package. You can buy it as a unit for a pretty good price. Also calls for 4S. Both have pushed hytros to 50mph.

Thank m8 will check it out

Here's the UL power plant for sale on OSE. $159 not too shaby.

How big is the boat going to be when you are done ?

Is not 1/8 scale going to be going to be 1/3 bigger than the UL boat ?

You might be asking alot to be running a 4S motor in something that big

That's just what I was thinking..

I'm not so much worried about the motor being able to push it as I am the transoms being able to handle the stress of the rudder and skid fin brackets in a corner. That soft balsa can't handle that kind of load by it's self. What do you plan to beef those areas up with, or have you even thought about it?

kennyach

the boat is 42" long and the transoms it two 1/8 ply glue together also the skid fin brackets in a corner is back with 1/8 ply the boat is only 10oz without hardware

eboat

If the boat is that big you will want at least 6S2P or 8S2P to run it

I had a 36" boat and a 1200KV motor on 6S2P

You could try this motor on 6S2P

It still all comes down to how much $$$ you have to spend

If you have to buy lipos and chargers also

The costs will add up fast

kennyach

Here the plan on the boat .just take an look it http://www.astecmodels.co.uk/plans.htm it the 2nd one down 1/8 atlas van line

kennyach

thank eboat .looking to part out about $500.00 to get running

eboat

I have the very same plans but I am building one that is only 24" long

I am only running on 4S1P

eboat

$500
I do not know if that is going to be enough cause you could blow that much on lipos and chargers

eboat

Big boats are fun but cost a load of $$ That is why I sold my bigger boat that took the 6S2P lipos

I can run 3 smaller (26 to 32" ) boats on the same number of lipos it took that one boat

kennyach

here the transom pic

kennyach

i have the chargers aready from when i own an hobby shop and the hardware i make myself just need batt and Strut and ecs

eboat

That will help some

kennyach

SV27dayton

sorry about the motor/esc/4S suggestions. I did not realize that boat was that big. Guess I've got lights on the brain.

eboat. Is your motor laying level with the bottom? IF so that would mean you are running an "S" bend in the stuffing tube/flex shaft. It's hard to tell from teh photo. If so have you done that before and are there any drawbacks? Sorry I don't mean to jack a good thread.
