actually the pressure system described in that link I posted seems to work quite fine. The main issue was with the pressure valve. The standard plastic one tends to get clogged and you lose tank pressure after a few flights. There is a metal version, more $$$ but it retains the pressure in the tank. A simple 6 oz tank gives about 5-6 minutes of smoke.

The smoke oil is controled via the dubro valve and that is connected to a dial knob on the transmitter so you can control the flow.

Pre-wrapping a copper coil around the muffler header is a must for this system.

Different things work for different folks I guess but I know the system works great and real inexpensive to boot. (I'm cheap too )
