Title: How to choose propellers and propeller nomenclature? Post by: naatumach on December 23, 2009, 11:19:57 PM Again quoting that I am currently very new to RCs and I first want to gather all possible technical knowledge i can, no matter how elementary it may sound.
Here are my questions: 1. For an electric propeller what does this kind 10"x 6" of nomenclature mean? I can understand what 10" would mean buy what does 6" mean? 2.What Electric Propeller, Sport Propeller, Pylon Propeller and Slow Flyer Propeller?

http://www.rcindia.org/rc-general-topics/propeller-what-do-we-understand/ has more details than you need for a while ;) You should use the search option to find such threads :) [2] This thread has a basic information on the difference between various types of props. The main difference is the rpm each is designed to run at. http://www.rcgroups.com/forums/showthread.php?t=846413 Title: Re: How to choose propellers and propeller nomenclature? Post by: naatumach on December 24, 2009, 10:56:04 AM If I am trying to build a model in which i have very low constraints of voltage and current. Which means that I shall not be able to get a motor of very good RPM. I intend to make a boat kind of a structure which works by pushing/pulling air through propellers. What kind of props do you suggest? And what would be the minimum RPM i would require.
The max voltage i get is 6V The max current i get is 400mA The weight of the structure would be 250gms I will be using a prop of dia less than 8 but I am not able to decide on the pitch and the kind of prop, slow, fast, sport. How many blades would be preferred, 2 or 3? Regards Vaibhav Title: Re: How to choose propellers and propeller nomenclature? Post by: anwar on December 24, 2009, 07:31:29 PM With those strict parameters, wonder if you should be looking at the the micro-flight motors like these.
