Its a brand new Arduino install (today) 1.8.10 with latest Teensyduino. I was able to do the prop shield calibration
Yes, I now see that the PropShield example in the Mahony library compiles . But now I get "Teensy did not respond to a USB-based request to enter program mode.". and pressing the button on the teensy 3.2 does not seem to help

I also installed (Library Manager) Mahony 1.1.0 which seemed to fix an earlier error. I wonder whre the .begin method is
My goal is an "air mouse" ie a teensy on my head
