Hi Chellie

That looks good, and should do the job.

But, my PicChip cost 99 cents, and can be programmed to do many things automatically.

With an evenings worth of programming anyhow

I made a couple of them for fellow club members that wanted to fly electric control line models. It was programmed to "first blip the motor" as a warning, then 10 seconds later, quickly ramp up to full power. Then run for exactly 4 minutes, then again blip motor power in flight, then cut power 15 seconds later. Wouldn't take much to include computer type jumper clips to allow digital changes in time for full power, increasing by one second increments to 6 minutes or so. No one has asked for it yet.

The entire circuit consisted of one PicChip, one resistor. That's it. (The resistor is needed for on circuit board reprogramming)
