Props

[merc-blue]

i have searched for threads on propeller science but couldnt find anything so figured i would start a thread, so far i have lernt about props 3 main things
diameter pitch, and the power from the motor and you want a good combination,

what i want to know is what is the affect on 2 blades vs 3 or 4 blades,

If you really want to understand propellers try http://www.mh-aerotools.de/airfoils/index.htm

It's not easy going but when you've finished you'll know more than most about how props work etc. The specific information you want is under Propellers then Equivalent Multi-Blade....

ok guys i now have more prop questions,
to do with materials, whats the difference between a composite and nylon prop? on a slower RPM is there any benefit on the composite over nylon as the only flaw with nylon seems to be flex, also the patten of the prop does that make a big difference? i just want to make sure im always using the right prop,
cheers

flexbility is the advantage AND the disdavantage of nylon.... ;)
