More progress on fuel/smoke/water system.
All fuel/smoke/water tubing identified for easy maintenance and troubleshooting if necessary.
The water tube is T'd off the smoke line going into the mufflers.
That same water tube will run backward to exit out the bottom of the fuselage to the spray bars on the wing (to be fabricated this winter).

The smoke fluid will be clamped/valved off (if I can get 1/8" ) inline valves?? when the water will be used.
For the smoke I will Y off the tubing after the T for water to seperate the lines (one for each muffler).

The key is to properly isolate the systems (water/smoke) from one another.
It will be an either or system, not simultaneous functions.

If anyone knows of a source for small 1/8" inline valves please let me know.

If they are made, they will have them! Brian

As you can see they are deep in tail section. The large compartment forward of the elevator servos is for installing batteries for CG,depending on the engine being used. Engine range is from a 60 to 100 cc .

At this rate, you should have time to rebuild ny 100cc Extra that needs some legs. It's interesting that they anticipate adding tail weight. Great setup with tray already cut out. Can't wait to see it in the air.

Don't anticipate needing to install the batteries back there.
It's probably needed if a 100cc engine is being used.
I don't think that aft battery compartment will be needed when using the 80/85cc engines .

Won't have too much of the winter to work on it as we will be away for most of it. Figured I would get most of the grunt work done and do the spray/smoke system afterwards

Started the design for the hangars/tubing on the trailing edge of wing.
Will be making 4 for each wing half.
The design I'm using should not compromise the air flow over the wing or the ailerons and flaps.

Could not source ball valves small enough to use with gas tubing.
As a result,I'll need to make some modifications to the initial setup by using Festo fittings and compatible tubing.
(Festo fittings cannot be used with Tygon or silicone)

Will be using a ball valve for smoke fluid and also one for the water. As it's going to be an either or system sharing the same tank, (smoke or water) not both simultaneously, I will need to shut off the smoke tubing valve when using water and open the water system valve. The reverse will be used when using water.

Each system (water & smoke) will have a dedicated check valve(s) (Festo fitting).
If these systems function as intended, I may add a second tank and pump to operate them simultaneously, time will tell........
