Beautifully done Peter, great attention to detail!
I'm guessing that your heart may be fluttering a little on the maiden ..........

Re: Jilles Smits 1/3 scale SG38
An initial balance indicated that I needed to put around 1.5Kg up front to a achieve the recommended CoG position (151mm from wing LE).
As the internal ballast box will only take 500g, the rest is located in 4 cylinders mounted on additional brackets in a manner very similar to that used on the full size.
The photo below shows the arrangement mock-up.
The rear brackets are bolted to each other through the fuselage, whilst the front brackets have since been silver soldered to the nose bracket and will also have a bolt through the fuselage in addition to 4 of the original 6 servo screws.
The bracketry & weights are currently in the paint shop.

External ballast bars painted & fitted with just a couple of spots of paint on the fixings now required.
About ready for what is hopefully the final assembly & balance check before handing over to Cliff for addition of the minimal registration lettering and then the maiden flight

Although it's not my type of model Peter, I have enjoyed your build. Best of luck with the maiden and I look forward to the pictures.
