    New to electric... Setting up boat

    I have been playing around with nitro boats for years, and am finally going to try electric. I just finished building my Dumas Deep Vee 20, bought a speedmaster stinger drive (3/16), rudder, and flex cable. Now I am looking into purchasing a good quality electric motor, esc, and prop and need some good suggestions.


    From what I have read on this site, I was looking at a Feigao 540 6L 4,096 RPM 5mm Shaft motor, a 60 Amp ESC and a pair of 5000mAh 2S 40C Lipo Packs... along with a good motor mount, and cooling sleeve for the motor.


    As for props, I have a couple prather B215 and B220 props, but I fear that they might be too big.


    Any help would greatly appreciated.

    RE: New to electric... Setting up boat

    I read through that a few times and came up with those items. I was just wondering if anyone had any input on how well or bad that setup would work out. I have also searched through the forums for similar boats to my build to see their setups.


    From what I have read I will need:
    1. Motor between 3000 to 5500 kvh, lower end due to mono hull
    2. 2 cell 5000 mah 25c min battery, run in parallel
    3. Prop 30 to 40 mm

    If yoou go by the calculator on the page that was given to me, it looks like the prop is too big, it recommends a 34mm prop. So an Octura X435 (35mm) seems to be a good starting point.


    I have been playing with nitro for years (mainly boats, cars, and airplanes) and was thinking about giving electric a try, especially since I am going to try to get my 5 year old son into boating. If not I will just go back to nitro and do what I am use to.

    RE: New to electric... Setting up boat

    I sold off all my nitro boats. Too much fooling around, added costs, all for a slower model. Keeping the gas hulls though. They are on a much different page.

    Setup Sounds good. Only change I would make is go up a turn or two in the motor department. If you get a lower KV value, you will be able to stick with more standard props. For example 3/16" shaft props. Smallest one starts at 37mm.

    Around 3400-3600kv (540 S or L size can )
    2s 5000mAh 30C or better
    X437 prop best suited for 3/16" shaft.
    120A ESC is recommended. Both as increased reliability and can be used in other models later on.

    Like always when you build a boat, follow that first run page on the site. Check temps often.

    Cool, thank you. I will re-configure with the different motor and esc.

    Thanks for the help.
