Hi Johnny,
We operate both, B2 and C1
B2 with Lycoming
C1 with Turbomeca
So consideration should be also your maintanance possibilities.
C1 different Cockpitlayout with electrics (Inverter, Main, SPAS) in ℅-Pilot overhead.
C1 faster start with gyros etc.
No need to switch generators on/off - just leave the switches on.
Only 30 sec cooldown before shutdown.
With VARTOMS (our) TQ matching is done automaticly
2 of the 3 C1 have more power than the B2s - the third C1 is said to be within the limits- but feels just powerless, when loaded
C1 no problems with cut grass on the intakes (B2 a pain in summer outside landings)
Any more questions?
