Considering the above, I have set now my prop. to 15.6=B0 which gives me a
good compromise for climb and cruise especially at maximum gross weight. I
hope that the cold air supply and a VP-prop will help!
During those test flights I have found out that my RPM indicator reads 300
rpm too low!
Any ideas how I could calibrate it?
Also my VSI is indicating 200 ft/min too little. I am currently taking
static air from behind the panel as the fuselage points did'nt give me good
readings either. Any suggestion for a good static air point?
