I was told by Dynon at Oshkosh that twin engine monitoring is one of the items on the to-do list. Just want to put a vote in for that feature. I know of 3 Defiants now using Skyview including mine, and that number will grow. I am waiting for the twin engine feature before I buy the second skyview screen, which will replace 2 VM1000 engine monitors. Between the Defiants, the AirCams, and who knows what else, there is a market for this.
