Is there a chart anywhere that compares the 2 types of motors...... power for power ect. Thinking of trying electric and would like to compare both types

I've not found an across the board spread sheet, the closest thing that I've found is on various manufacturers websites is things such as this:

Converting to electric is done by basing your choices on the plane and how you want it to fly, not on the size of the recommended glow engine. Electric and glow power are so different that making direct comparisons is misleading and usually inaccurate.

The biggest issue is, the electric motor is only a part of the power system, and really, the least important part. It really is the equivalent of the crankshaft in a glow engine in that it takes the energy from a chemical reaction and transfers it into rotational motion. Whereas that chemical reaction happens inside the combustion chamber of a glow engine (i.e. the BANG as the fuel ignites), the chemical reaction in an electrical power system happens in the battery. Thus, the battery can be considered the combustion chamber, and the battery's voltage the equivalent of displacement (cubic inches).

One example of a company that tries to make it easier is Horizon, with their Eflite line of outrunners. They number them with glow engine "equivalencies" but the stipulation there is that you need to also use a prop and battery from the recommended range to get that performance. In reality, you can get as little or as much power out of the motor as you want, up to the point where the motor becomes overloaded, by decreasing and increasing the battery voltage, and/or decreasing and increasing the prop size.

Matt's explanation is excellent. A slightly more simple way to put it, is it is about power-to-weight ratio. Companies are giving you so much information these days on their brushless motors (power output, recommended props, etc.) and lipo batteries, that it's making it easier to match up power systems for nitro-to-electric conversions. You'll find that a watt-meter is an essential tool when running electrics. Here is a little chart for ya' on recommended power-to-weight ratios based on your application.
