I have a R30 V1 and crashed it (tipped it really) in high wind a couple of weeks ago. Finally repaired it with the usual crash parts--spindle, blades, double links, etc. Using the Mavrikk woodies in the crash kit.
Spooled it up last night to check tracking and see how it goes. Blades track perfectly and no vibration anywhere that I can see.
But it seemed to run a higher head speed than before. I keep the pitch at midstick at 6 degrees in Normal mode which normally gives me slowish head speed. My pitch gauge still says 6 degrees (maybe 5 3/4) at mid stick.
Now I'm hovering below mid-stick with a higher head speed than I want.
I think somehow I'm actually running a lower pitch when it's actually running than sitting on the bench. If I increase the pitch curve then I will be well below half stick. For the time being I reduced my throttle curve substantially. BTW I'm running my OS 32 almost too rich as it will only smooth out after about 2 minutes of hovering, so it's not leaner (w/ more power) than before--I think.
What could have changed? Maybe my thrust bearing ball race (not the two grooved "washers" is backwards--I don't know if the direction matters?
must have been a downdraft
