Model Forum / Radio Controlled / Water Models / August 2008

Hello

I live in Brazil, and at this group I am a newcomer.

My interest for RC boats becomes from a Cracker box 1:10 that I am
building.
In fact I have many doubts.
Engine, I intend to use a Hyperion Electric engine Z3007-10, brushless
type, whit a lipo batteries 3S -10,5 volts.

My big doubt is about the propeller, size and pitch, also if I really
need a cooling system, because this engine is used on RC gliders, and
remains closed inside fuselage, without any cooling system.

Many modelers in Brazil are advancing me, about the worm at the engine,
but I do prefer listen from people that in fact have some knowledge
about boats.

Best regards
