<div>I&rsquo;ve noticed that there are generally two types of propellers available.Most wood and hard plastic (Master Screw) are intended for gas powered engines.A softer, more flexible prop is recommended for electric engines (these are generally lighter grey).
</div><div>My question is, why the use of the lighter prop, and what are the issues with using a heaver prop on an electric?I&rsquo;ve had excellent results using a 8x6 MasterScrew on an eFlight 400 &ndash; several dozen flights with no degrading of power or battery life.

I assume that when you say two types you're ignoring slo-fly props, a third type. The heavier props are to handle the high torque of a engine's power stroke and provide flywheel to keep it going. There is no reason not to use the fuel engine props on electrics, other than some extra weight if it's a low torque motor. On high wattage motors it's best to use the heavier stronger prop.

Pete ... try the XOAR ones ... try it. You will be surprised.

Thanks all - I'll check out the XOAR props as well.
