Propulsion
« on: March 06, 2010, 02:53:45 PM »

Guys I need your help (again) :embarrassed:

I got few plans for my next project: patrol boat in 1:24 which length would be around 1,7 m for propulsion it would be needed 3 motors with 3 propellers. Those propellers are in diameter 58 mm, so they need lots of power. What kind of propellers should I use ( 2 or 3 bladed) and what kind of motors . I usually go with Speed (brushless are bit pricey) but with propellers this big? I thought 700 series with gears or 900 series direct drive. Speed I would like to achieve should be at around scale let say around 9 kt.  Can you direct me to any good links or even better does someone have any experiences with problem like that?

Thanks in advance
