So I'm getting into R/C flying and got myself a nice, but pre-owned trainer model. One of the things that need replacing is the propeller, which is a 2-blade nylon 10x8 with too many signs of damage for my liking.
I'd like to stay with a 2-blade 10x8 to not get into any troubles with regard to overloading the motor or ESC. But there's more decisions to be made aside from number of blades, size and pitch.
- symmetrical vs. undercambered?
- swept-tipped vs. straight-tipped?
- nylon vs. wood vs. carbon fiber?
Given that I'm just starting out here, it seems staying with a straight-tipped, symmetrical nylon prop would be the conservative choice. I'm wondering about these things though:
- since the "collision object" putting the propeller blades at risk the most is the gras you land on, might carbon fiber be more durable, just cutting through it without taking any damage?
- might wood and carbon sound better than nylon due to being less flexible?
- might wood and carbon be more efficient than nylon due to being less flexible?
- how much at-risk for unplanned rapid disassembly from just doing their jobs are these three materials in comparison to one another, a.k.a. what's their lifetime in the best possible case of never colliding with anything but air molecules?
- what effects does symmetrical vs. undercambered have?
- what effects does swept-tipped vs. straight tipped have?
