I would like to fit a smoke system in my Goldgerg Extra 300 / G23 model but know very little about doing so and would appreciate some advice and suggestions on the easiest way to do so.

The Sullivan Skywriter will be your best bet on pumps. B&B makes a smoke muffler/manifold that is fairly cheap, Bold Muffler makes a pitts style smoke muffler designed for the G-23. Super-Dri is the best smoke fluid on the market, but diesel fuel, transmission fluid, and kerosene cut at 33% does pretty well. you need to use Neoprene tubing from the muffler and Tygon everywhere else. Make sure your smoke tank is much smaller than your fuel tank. Good-luck

One thing to know is that smoke is messy. Like pumping oil onto your plane. Sure, once you get it dialed in it may get better, but your finish needs to be able to deal with it. This is something rarely brought up about using smoke. Everything has to be optimized, otherwise you can have a real mess.

Thanks guys for your input, especially for bringing up the "messy " bit as I never gave that much of a thought. Becoming tired of having to deal with the constant exhaust mess from glow is one of the reasons that I find using gas so very attractive.....no mess. This puts a whole new spin on the smoke thing, at least for me.

The good thing is, a smoke every once in a while keeps the muffler insides clean. (no pun intended )

Why do you say this? I have always used the same size tank as the fuel as that smokefluid does not last that long as it is.

Usually an engine will consume about the same amount of smoke oil as fuel.

Is that with full time smoke? Wouldn't it vary with how much the smoke is turned on and off?

This has not been my experience, though perhaps you have used more smoke pumps than I. I have only used 3, all different types. The smoke oil seemed burn 2-4 times the amount of fuel used.
I always found to use the smoke sparingly turning on and off for a given maneuver to conserve for flight duration.

You need to adjust the flow for the best smoke. It is easy to inject too much, which cools the hot gases in the muffler and ends up making less smoke, wasting smoke oil, and covering the plane with unburnt smoke oil.

I too turn my smoke on and off. Usually smoke on just before a maneuver, on during the maneuver, then smoke off shortly after the maneuver is complete. This actually makes the smoke presentation more dramatic.

How much smoke oil a setup will use depends not only on the user, but on the setup as well. Some systems smoke more efficiently than others. I guess when my systems are on, they use a bit more smoke oil than gasoline. Plus, when I said they will use about the same amount as gas, I meant comparing to an engine's gas use when running at full throttle, and we rarely, if ever, fly around at full throttle all the time.

Irun a Sonictronics pump on a DLE20 with an 8oz smoke tank and it will last about 45 sec full on where as the planehas a 10 oz fueltank and willfly 15 min. I only run the smoke on maneuvers. Getting the flow controled correctly will minimize the oil on the plane and most of it is only on the bottom of the fuse and staband cleans off easily. Not at all like glow slime

Wow 45 seconds is not long at all. that seems WAY too short. I am not familiar with that pump. Is that an actual "in flight" smoke pump as opposed to a smoke tank fueler pump? I guess it must be as I don't think there is a flow adjustment on a field fueler pump.
On the other hand I run a 16oz tank with a Sullivan and might get 3-4 minutes. So maybe that's not much different.
