Oh well here goes...
Not as good as some of the military ones, but a learning curve none the less..
As a new flight instructor on a Bell 47, very keen. Had an uneventful flight to a local airport, nice landing by the student, all going very well.... got out a looked at the tail boom which is now completely covered in oil!! AARRGGHH what the hell happened here!.. Well now I always make sure the oil dip stick is in before I get in! and not resting the frame. God it took ages to clean.. who was the dip stick then!!
