Does someone know why electric props have have such a different bladeshape compared to other props.
Example, a 16x8 electric looks completely different from a regular 16x8

Re: Electric prop question

I believe the reason is to make them more effecient and as they do not have to be as strong, (no vibration from an electric motor), as a glow/gas prop they are undercambered. An electric prop will produce more thrust than a glow/gaqs prop. Generally an electric prop will turn much slower than a glow/gas prop, as an electric motor will turn larger props than glow/gas motors. A slow turning prop is more effecient than a high speed glow/gas prop.

Re: Electric prop question

There are many different shapes even of electric props. The APCs are a little far out compared to the GWS and Powermaster. The powermaster are not unlike the glow/gas props. I use a Topflite 13-6 wood, glow prop on a .46 sized electric because the APC was showing stress marks around the blade hubs.
Tried for my kamikazi pilots licence. Flunked the test.
