Not planning to break any records, just something to through in my pond which is only 90' x 60'. I'm planning to build a rigger about 18". I have a Eflight outrunner 370 1080kv 110 watts max. A 20amp non-water cooled esc and 3s 2200 and 1300mah batteries.
Do I have a chance to make this work or am I wasting my time? Do I need to watercool the esc and motor or will they be ok because of the low amp draw? Should I run piano wire drive system and how should it be supported? Completely sleeved or just supported in a few spots?
Any suggestions will be appericiated.

Are you aware of this kit? I have owned one of these and they are blast to drive.

Electric, Can you give us more details for the motor, ESC, battery, prop and other recommendations to get this boat up and running.
I own this micro rigger. I just don't like that it is not water cooled. The out runner gets way to hot. I would like to convert it to a water cooled 3s set-up. What are your thoughts?

Thanks, Allen

What motor,esc and battery are you running in the mini sprint? What speed?

Sorry guys, it's been too long since I had it. I remember that I ran the standard motor that you bought off of the website where they sell the boat. Could not put a GPS in there because the hull is very small. I agree with you that I would have liked a cooler running set up and a water line (if you could squeeze it in there) would help. Here are some useful links on the boat:

The boat has handles very well and turns great. If I were to build another one, I would think about making the tub a bit taller to give myself a little more room for the battery and esc.

I know this is bigger than you asked about, but I should at least mention it to you. I have owned this rigger as well and I have run it over 60mph and it handled like it was on rails. Really an awesome boat. If you just put a standard sv27 type motor and decent esc you will see low to mid-50's. My club doesn't really run riggers so I eventually sold them off to finance other projects.
