How to build smoke exhaust system on your RC Air plane
In this video we will show you how to make a thick white smoke trail after your RC Air plane.
I have a Calmato Sport 40 with SC(Magnum)46 2 cycle engine and the Du-bro Super Smoker valve DUB255.

Whith the 2 cycle engine I get airpressure to the oil tank from the crankcase back cover. And inject the oil on the exhaust "header".
The valve closes both lines in and out.
I Also use preheating from the sylinder top + heat insulating tape around it.
If you have a 4 cycle engine you dont have overpressured crankcase.
But there is two other options: The venturi effect http://www.rcdon.com/html/the_ultimat...
or smoke oil pump like skywriter.

(you don't need the dubro valve then)
BUT.. in corcholato's case he actually did get his 4cycle engine to smoke by the 2 cycle prinsip.
Thick smoke is depended on evaporating efficiency.
This can make it better: hotter exhaust gas, higher oil temperature, higher oil pressure, higher nozzle spray efficiency.
For best performance, use Smoke oil http://www3.towerhobbies.com/cgi-bin/...
You can also use diesel, but will produce less smoke.
The result with diesel is • 2-stroke RC Plane with smoke system in act...
from Lie Airsport RC in Skjold.
