EC120 start and re-start have been discussed at great length on and off this forum. It's not a big deal as long as you follow the correct procedure. You can shut down, vent and start again immediately with no problem AS LONG AS your battery is good.
Main issue is that once you go through the gate the battery needs to retain the voltage to operate the relay to open the throttle stop so you can close the juice should a hot start look likely. Unfortunately, that could be due to a sudden drop in battery voltage itself which means you are buggered. Just watch the voltage and if it heads south of 17V then consider aborting and rolling out the ground power.
Some people, pilots and pax, prefer a bulkhead between them and a lot of pax don't like the way the 120 flies - waves its nose if you are not very careful and some, like the one I fly, have vibration problems that have proved hard to get rid of.
New modular Bell helicopters should give EC a run for its money.
EC's power is fine at sea level or ISA but in Africa or central Spain where you get hot and high, they just don't perform and take about three miles to get through transition.
Also, you can only take a v small adult or child in the front if you have a few pax and although it will take off and fly okay, you are quickly out of the CofG envelope which could get interesting if you have to auto. Have the findings on the US police 120 engine failure and fatal crash come through yet ?
Many guys don't like fenestrom and it is weak when hot and high - heard it is much smaller than originally planned to be - but you get used to using more foot earlier than on conventional tail rotor system. And it is sooo quiet, it's usually landed before people notice it arriving.
Baggage compartment is huge and with removable seats, access panel to rear and sliding door, the features combine to make a versatile machine for filming and other fun stuff. We have used it as a baggage carrier when taking two or three fully loaded 407s somewhere. It almost keeps up too.
VEMD is like a traitor on board that doesn't actually give you a fair chance, like say FADEC on the 407 does. Good for owners, unnerving for pilots.
It's a helicopter I like to be seen getting out of, review emergency and start procedures very carefully before flying, and don't trust the way I do a Jet Ranger. Wish it were a mini Squirrel but it ain't....yet.
