Engine Exhaust Deflector
 
I have these engine exhaust deflectors that I use. I have one on the airplane and one spare. I have been trying to remember where I got these tubes. This airplane was built back in about 2016.

Iím not one to just throw away an inoperable item. I like to, first, salvage parts that still have some use; power cords, screws, switches, ledís, etc. For example I have a microwave switch that powers my onboard glow igniter on my engine test stand. I just turn the igniter on or off as needed.

Yesterday I decided to finally go through 3 old coffee pots that I needed to discard. They have been stored for a long time. Well low and behold, that is where I found my exhaust deflectors. Now I have a good supply of deflectors. Some as in the photo and some black in color

Hi!
I saw the plane (with plastic tubing fuselage) in your picture and got curious about the C of G as he engine sits so far forward.

I made the fuselage longer than normal requiring moving the wing some. Here I am working on the CG using a Vanessa Rig.

If it's working for you that's fine, but the ailerons are part of the wing chord and so should be included in any CG calculations or measurements.

The ailerons may not stand out but they are included. The picture shows the entire airplane and it flies well for me. I may, just, not understand your point.
