Slap a luggage pod under a 500, theres your baggage. They are the only small turbine that really will do a vertical at max all up weight with power to spare. EC 120 certainly doesnt. Also have a cruise speed of 130 kts ( some will go faster) uses 110 litres an hour. Therefore your extra speed means less fuel less component times and therefore cheaper to run ! Just compare R44 fuel burn with the £ 1.80 a litre cost v .60p per litre for jet. Thats £ 120 ish for the R44 for 110nm v £ 65 for 130nm in the 500 Plus 500 will hold its money, have owned 7 of them have sold each one for more than I paid for it, try that with a 120 !
There is absolutely no comparision as to which is the most fun to fly !
