Av8tor, you were right.
The extensive mid-range burble is helped by increasing propeller load on the engine.

Master Airscrew 18-6. 8,300. Burble up to 6500-7000
Zinger 18-6. 7,600. Burble up to 5000.
Zinger 18-8. 6,500. Insignificant burble, quieter, faster.
Zinger 20-6/10. 4,750. Did not attempt flight.

While it was nice to fly without the burble, the Zingers didn't really float my boat


Next I will try an APC 18-6W
