my suggestion is get the engineers to wind the pitch aduster close one turn.But u have to be carefull of over speed very quicky.
Lets see what eveyone eles says.

Problem:-
Lower collective,governor off,wind off throttle,speed back to 60/65kts with right rudder.What happens next??
Well,rotor rpm decreases but collective is all the way down.Reducing speed further may help but only in the short term.
Only solution is to wind on the throttle and overshoot because the aircraft is too light with only one p.o.b.
Any ideas??????
Always take a busty blond when practising these exercises???
But what happens if it really quits when solo??

Sounds like a good move. IMHO, the checklist was devised to cater for low hours pilots like me. If anything is not exactly as it should be, you ask an engineer, and use your common sense to decide if a don't worry it'll be ok' answer is acceptable, or just don't fly till it's sorted.

The Robbie's fairly simple, and you can choose to only fly it with zero defects (other than being a Robbie) and rarely be disappointed: you commercial chaps flying every day with half a dozen deferred defects in thousands of different components and deciding if it's in or out of a tolerance level have a much harder job to do!

Auto RPM
as a verrrry simple excercise why not refer to the Robinson maintenance manual page 10-40. follow instructions, note (collective full down).

Think- what will be the minimum weight, apart from you and no fuel that is.
Is that different from basic empty weight plus min allowable cabin weight?

Subtract that from max AUW, divide the difference by the allowable auto RPM range.

Please do not be surprised that when you experiment with different weights whilst observing the auto RPM that there will be a straight line variation between auto RPM and weight. (under identical temp conditions)

Take this formula to the bell 47 (say) where there is no convenient auto table and come up with the correct auto RPM settings every time for every different loading configuration.

motto, when all else fails refer to the manual.

R22 clutch motor
 
Where I am at present instructing on 22's,we seem to be having problems with our in line fuses keep blowing on different aircraft,one of which was yesterday.Someone was saying that if they get a bit damp they will pop a fuse ?
Over the many years of r22's this statement is totaly new to me,after picking up non hangared robbies.
Someone has also suggested that robinson has contracted out the manufacture of the clutch assembly to a contractor,over the last 12 months is anyone else getting this recurrent problem...... ?:ugh:
