Regarding the question on balancing props.
1 It doesn't work well with a sprag clutch - too many variables
their pitch after it has been done
3 I can recommend the following but they are expensive, be warned
4 I agree with jerry, dynamic balancing is the better method
no lectures

Subject: Dynamic Propeller Balancing
Hello fellow aviators,
Noel Trigg Associates Limited
We provide a mobile dynamic propeller balancing service for your beautiful
aircraft. With the help of the Rotortuner which I invented while I was with
Helitune (which I founded 19 years ago) we will balance your prop to perfection.
We use our split balance rings which fit under the prop retaining nuts on the
engine side of the gearbox output shaft to provide 12 balance holes to which we
attach appropriate bolts, washers and nuts.
We provide this service at Aero Developments at Kemble or at our base at Shobdon
The benefits of dynamic balancing are:
Reduced cyclic stress on the engine and fuselage
Reduced fatigue on the pilot and passenger
Longer life for your radios and instruments
Vibration free camera platform
Extended engine time between defects
Reduction in oil leaks and seal failures
Reduced wear and tear on all flying controls, bearings and linkages

>I am not sure if he does it - spinner on.
>I'll try and dig out his number if someone does not beat me to it.
