Hughes500, you want to be careful about your statement with regard to manufacturers and component times!
Last time I looked at a Robbie flight manual (R22Beta) it said that engine start to engine stop was to be regarded as flight time, in other words whatever the hour meter says, and that if you had a collective switch fitted, then your flight time is the hour meter + 10%.
Anybody close to an R22 flight manual able to confirm that this statement is still in there somewhere? Many many moons have passed since I last looked at a Robbie up close
