New boys first scratch build

Hi All

       My first time to try a scratch build   :-\

       A friend gave me a few photos of a channel tug he saw on holiday, and said you think you can build one  :o  Lets start Pencils, rubber,Paper, drawing board, ruler, think that the lot.

that works for me - next springer I'll remove the slight curve in the deck - well proportioned model -

Hi all

 In the tradition of "Arrow5" , just found a sheet of HDF melamine coated board about 7mm thick and very strong . Ha now to start cutting the hull and deck , still think about motor power ? how about twin 540 with gearboxes 2.5/1 on 6 volts and 40mm korts nozzles

modeltugman : The problem I have found that A lot of speed controls do not like 6VOLTS . They say 6 to 12  volts ,but when voltage drops monumentally for what ever reason they cutout .  On TUGS  I use 7.4  or  12 volts  and solves   that problem  . On the gear boxes I use 5/1 for bettor  bottom end control  , and still good top end .  Hope this is some help .                       PUFFIN

I had a 6V Mabuchi motor in my 43 inch tug which ran from a Futaba speed control. Worked great.

Check with Action RC Electronics for a suitable ESC.

Hi All

        Power units will be 2 x 540 2.5 / 1 Motors with gearboxes run 40mm korts steerable nozzles, on 6 volt SLA batteries.

        Have looked at 12v with 6 / 1 gearbox but it has less revs , Ok more torque but not need with only a 40mm prop.

        ESC will be a ACTion P94 unit. setup as a mixer

   P.S. Hull Photos to follow

Hi All

     Have cut and glue up the Hull , and cut a spare deck plate to work and test things out on .

     the glue is " Gator " a Waterproof Polyurethane D4 type, very strong . the hull size worked out at 297mm x  586mm ( 11 5/8" x 23" )  it will be a good size to carry.
