The new electric designs are far better at constant speed.

applause!! applause!!!
They actually have a hidden reserve of power, if your setup lucks up and leaves one hidden in all there somewhere. Electric motors have a characteristic that our glow or gas doesn't. They spin the prop up to their design speed if they can, and that's it. Sounds like a problem, not a benefit, right. Well, they do something more when they encounter certain conditions.
You've chosen your prop after extensive tests, right.
You've got the speed you want and decent pull over the top of loops etc and noticed the magic "electric constant speed vertical". How did that happen? That vertical?
It's like something extra kicked in. You were at full throttle starting up and right where the glow/gassers would have slowed down a bit, that electric motor seemed to have found an extra bit, like the turbo had kicked in. It had found something extra. An electric motor that has reached it's design rpm won't slow down if it encounters more load, if it's got a power source that'll keep giving more. Those suckers do just that, suck power as needed. If the ESC doesn't hold them back, and the battery has more capacity in it, all you're going to lose in vertical will be from the prop slipping.
Much as I hate to admit it, electrics do have more than one worthwhile attraction. [:@]
