Thanks for your help. My target RPM on the v-twin is going to be in the 2,500
- 3,500 range. That's probably as hot as I could turn it and not overheat the
motor.

My intention for the smoke system is to produce a 50' dia. cloud of dense smoke
while still on the ground at the end of the runway, ramp, etc. Then slowly
emerge from said cloud in dramatic fashion. Don't know if that'll work, but I
think its worth a try.

Thanks again,
Harry
