I have the Hangar 9 Pulse XT 40 with an AXi brushless outrunner motor equal to the E-Flite Power 46...(4120/14 )
There is a guy in our club with the Evolution .46 glow engine in his...

The glow version has a little more top end speed, but I can get off the ground (with a little breeze ) in less than 50' T.O. roll
My .46 equivalent electric set-up has the "feel" of a glow engine that's much larger than a .46 as far as low end "grunt"...more like a .70 4 stroke.

The only potential drawback (if you need to call it that ) is that my batteries (4 cell 3200 Kokam's ) cost as much as a whole season's worth of fuel.
