Don't spill your coffee in the vicinity of or directly behind the captain's seat. There's a PCB under there that does a whole bunch of PFM for the aircraft, and it does not like coffee. Otherwise it is a pretty docile machine to fly. Don't expect many greaser landings though--because they only occur as a result of accidents or 4" of snow on the runway. . .If you are operating on gravel, don't use reverse. It will stop easily on 3000' of dirt without it (just use full beta and brakes), and the reverse will only trash the props and blow dust and stuff through the hot section.. .I only flew about 600hrs on them, but had few major problems.
