    RainX B-28

    Hi,

    Im currently making plans for my first rc boat and was wondering about a couple of thing´s. From the beginning I was suppost to buy the Graupner B-28 hull but soon realized that it was discontinued, after some searching this hull came up at an american shop. It´s a 41" g.fiber 2 steped B-28 batboat, probably something asian, and looks really nice! It´s delivered with .18 nitroengine, tuned pipe and alu.hardware.
    The stuff im awaiting to replace it with is:
    Feigao 580L, Turnigy Marine 180A, Turnigy 3s 5000mha 25c some Graupner carbon props. 42x1,4, 42x1,4x3, 45x1,4 and some noname 43x1,4.
    Im planing to run 2 x 3s.
    The esc and the motor cooling both has 2xinlet and 2xoutlet does that mean that I have to have 4xwaterpickup´s or can use 2 and recircle the water with a peace of tube, and in this case is there a risk that it would be insufficient ?
    What speed´s are possible with this setup, if the hull is ok ? Weight is 4.63lb / 2100g with nitroengine, pipe, rail´s and hardware installed-Est.400-500g / 1lb for this.
    What prop. is most probably suited ? What runtimes can i exspect ?
    All is ordered.
    Sorry if the english i poor ! SWE

    Use one pickup to cool the ESC and exit. Use the other pickup to cool the motor and exit.
    Which wind of the 580L motor will you run?
