My Futaba 9cap Supper has a great set of timers. I can set them up so the timer starts when I push the throttle of idle. Keeps track of the time in the air, and time on the model. The only thing more I could ask was to be able to hear it. When I was trainging, after a couple close calls wtth fuel, I picked up one to the old clock work timers with a bell at the local thrift shop. No funky sounds, no ring until you shut it off, just one really loud DING when the time was reached. Cant beat them
