Remove the middle prop before sailing, it will act like a brake, even if you have it free wheeling.
Just make a tapered cone to put in its place.

Been there, got the t-shirt, and baseball cap.

Hi John
           Hope all goes well with the maiden voyage. What batteries are you intending to use?
Cos you'll need a lot of volts to get that moving. Don't get caught in the power/weight trap O0

Regards Rob.

Hi John
          Good luck however I think you may be disappointed :( with the performance. Try 16.8v then she might go well O0. I know this from my 78ft Higgins to the same scale, they need power with little weight to look right.

Regards Rob.

Down the lake this morning windchill -3 (Must have been mad!)
Anyway just a touch under powered need to bring middle prop into play i think ?
Also move batt/pak aft running v/wet , bow down  c of g wrong
Useing 14.4 volts ,F.R 30 HX e.s.c, x2 M.F.A  4.5-15V RE540 MOTORS ,40mm 3/blade brass props.
What do you think best choice for center prop would be? matching,700bb or speed 600?
And would the e.s.c cope with 3 motors.
Cheers

Hi John
         40mm three blade props are not helping. Before you spend any money try 35mm two blade, works for me. Or the best choice would be to run 14.4 volts to the 700bb running 35 / 40mm prop and remove the 540's.

Regards Rob.

Hi All
Go to start to tidy her up a bit.
Her hull is quite badly painted curtains,varnish (gone pinkish!) ect.
Rubbed her down smooth now. Ive never painted a boat before !
So brush or spray (not to bad at that) , one colour or camo.
Any ideas ?

Hi John
I would redomend you paint the PT Boat In what ever you feel like
Below is a link to a book I bought and Would recomend it. It contains good pictures, diagrams
for the PT boat and their weapons also there is good colour pictures of some of the
colours and schemes painted on the boats

Hi John
I agree with Rob, try 2 bladed 35mm props preferably with a fine pitch before you do anything else.
It worked for me.

Hi John
          Any progress with the 80ft? On the subject of painting the model, I use acrylics because they are forgiving if used with or covering other types of paint e.g enamel / celulose. They also cover well either brused on or sprayed. Try the Tamiya acrylic in aerosol form for the the bulk of the operation then brush the small details. They correct colours are available for your elco.

Regards Rob.

Not a fan of running cells in parallel, it has been discused on hear many times so will not go in to it again , but if you have more than one speed controller I would think about splitting it up.

That would be much better , less chance of damaging a pack.
