480
Spent some time flying one...about 350hrs in it.
Typical C-20 operation, torque gauge appears lifted right from a 206, 'cept its redlined at 72%!! as the transmission may have been lifted right out of a Festiva! We actually had a tranny give out on us in low hover...customer support left a little to be desired, but maybe thats improved.
It looks heaps faster than it is, 90kts on a good cool night but had some interesting quirks. As you approached Max Q in flight, you knew that you were approaching 90kts because the airframe twisted in such a way that the passenger door would 'pop' open with a distracting change of pressure! and you knew that 90kts had been reached when the pilots door would 'pop' open as well!
Its a machine that could get you stuck into a confined area as it really couldn't pull the skim off a rice pudding.
The handling, despite being unboosted, was very good and predictable but there was one 'gotchya' in the collective. While at flight idle, it would tend to creep upwards, sometimes rather abruptly.....never forget to friction it down should you need to take your hand off it!!!...I don't know whether it was particular to our machine, or characteristic of the type but was a dangerous quirk.
The auto rotative characteristics were wonderful. Very forgiving, lots of inertia...really no excuse for not keeping the greasy side down!
Great visibilty in all flight regimes, plenty of tail rotor authority, very good adverse wind characteristics.
Hightlights - easy to handle, fairly smooth and quiet
Great autorotative handling
Lots of tailrotor ( but could really be just lack of Q!)
Reliable powerplant....the C-20 is topped to about
240? hp....should easily run to TBO
Fairly inexpensive to operate and purchase
Downsides - Needs more ummmmphh (a better tranny, which I
believe has been addressed in newer models to a
certain extent)
Relatively unimpressive cruise speed
Airframe weakness
Customer support
Exhaust is under the belly....extreme fire hazard
during off-site landings and is prone to cracks
Heater was weak for Canadian winters.
Hope this helps!....insofar as DOC's go....well i jusat flew 'er and fueled 'er.....but I think you could count on about 60% of a 206
