Thanks for your input guys; however, I still feel like I am lacking in my understanding of how to go about this conversion.
Here is what I found on the OS website,

Using a conversion table, a two stroke OS .46 AX at 1.65 HP would be the equivalent of a 1.23kW motor.
Does this mean that I would want to replace the Glow engine with an Electric motor that has a rating of 1.23kW, or is there more than meets the eye?
Also, the OS website says that on the high end the prop spins at 16,000 RPM. I guess I never realized they went that high.
It appears that on the Hangar 9 website you gave me, they sell an 'electric prop.' I don't see what would be different for an 'electric prop' or a standard glow prop. (I suppose the airfoils are different on the blades?) If so, why? The power source might be different (Glow or electric) but that should not affect the prop. I would except to use a 10x6 if I use a Glow engine or an equivalent electric motor.
Will I have to buy 'electric props'? If so, what RPM should these props run at? Will they be the same as Glow, faster, slower?
EDIT: Also, I happen to have a model motors AXI2814/10 brushless motor which was going to go into another (smaller) airplane. I do not know if this would be the right size for this airplane or not.
