I've been a long time fan of the ion engine so I've been thrilled at the chance to use/play with them. Yah, they're slow and use little fuel, but they do offer an option for the long distance drive. But, I'm finding it a real challenge to use them in the game simply becaues of the TIME. I was attempting a short little run from Kerbal to the moon to act as a tug there and I'm supposed to throttle up and maintain a heading for 3+ hours? Really? I've got to sit at the keyboard and do nothing but watch my heading for 3 hours? No way I'm sitting at the keyboard doing that for that period of time. What about those LONG space flights, 4 days of holding? Surely there is a game sensible way to make use of these engines that's practicle to we the gamer behind the keyboard? Am I missing a trick?
