heedm,. .You are right, in fact the issues are much more than two sided!
Carrying "extra" anything is always going to mean that you carry less of some other things. It is grand to see how the marketplace values the various balances we attempt. For the user, that extra engine carries lots of advantages, but also costs more to buy, insure and operate. The EH is estimated to cost about 35% more to operate per mile than roughly comparable two engine helicopters. I'll wage that a one engine helicopter is better yet in terms of pure economics (but they are not permitted above 20,000 pounds, unless equipped with fewer than 10 seats).
All being said, more power to hover means less fuel available to go somewhere, in the inexerable laws of design.
In another thread, the Gnome equipped Wessex is lauded for its awesome hover power, and it similarly has greatly reduced range as a result.
You buy what you need, we'll build them. It works just that simply!
