Nice day here today . Got a chance to run my DA-60 again. (2nd and 3rd run ) on this new motor.
Tried the Mejzlik 20x12 ( 3 blade ) got 6700 rpm ( short burst of full power )
Tried the Mejzlik 23x8 ( 2 blade ) got 7200 rpm ( short burst of full power )
Running 32:1 break in oil and motor is running rich ( have not touched needles yet ) I think these motors are going to need 24x8 or 24x10 props
I'm thinking , when a person starts leaning it out and go's to Synthetic Oil the rpm is going to go up some more !!!
