SKYWRITER SMOKE SYSTEM (SUL753)

The Skywriter Onboard Smoke System is a compact, electronically controlled setup for producing smoke trails on model aircraft. It uses an onboard microprocessor to regulate the smoke rate, with a programmable radio that lets the pilot adjust output mid-flight or tie it to the throttle servo for automatic control. The pump features an ultrasonically welded direct-drive head and weighs less than four ounces.

The system runs from 4.8V to 12V power sources (6V is recommended for best performance). The kit includes tubing, fittings, a double-screen filter and a check valve—everything needed to install the unit except the smoke tank and smoke muffler.
