MartinCH,
Fuel control is on floor next to collective on Astar, unless you have twist grip option. Fleet I fly don't, so yep training pilot controls throttle....it's all good,just make sure ya don't pull throttle back too far....whoops if you do....

no idle stop. As for main rotor rotation on EC, after a while makes no diference. Our fleet consists Astar B2's BA, Bell Longrangers and 205, we often hop between a/c, don't have to think about the difference the blades are turning.....
