At the Santa Cruz Flats Race the top Moyes pilots often flew near
each other. I asked is they were communicating. Here's Jonny's answer:

I saw you asked about if the Moyes boys flew as a team on radio.
Phil Bloom flew with his team, Olav had no radio. Kraig's radio only worked when
you were next to him, maybe antenna issues. Tyler's radio worked. My headset was
broken first day. Ran out of batteries on radio the second day. So there was not
much team work in the air but we did strategize before takeoff.
