The Electric Jetpack is a simpler, more easily recharged, and otherwise mostly superior version of the conventional Jetpack. Flying is performed by holding down the jump key. The Electric Jetpack is limited to a maximum flying height of ~185 meters (blocks) above the bedrock layer. For comparison, the normal Jetpack is limited to ~245 meters above bedrock. When the next version of Gravitation Suite gets added to the modpacks we will have: Spoiler ChangeLog of Gravitation Suite 1.7: + Added new cool item "Advanced Jetpack" -> energy storage 1 000 000 eu. -> can charge at MFE, MFSU -> overlocked engine - max height now limit to 256 ! (energy consumption 50% more than standard Electric Jetpack) -> supplies with energy your electrotool (as drill, saw, laser and etc..) -> can enable and disable jetpack engine for your convenience ("Fly" key) -> boost mode (energy consumption x5 more) -> advanced visual indication of charge state and work mode (you can change work mode by shift "Space bar" and press "Mode key" ) So I know there are a lot of people who want this and also quite a few that are fine with the Electric Jetpack. I like the idea but at the same time I'm one of those people avoiding the Gravichest because of everything it offers. I probably did my math wrong but it looks like 2 hours of usage in hover mode. I'm just curious about how some people feel about this addition and whether or not they intend to use it.
