I will put together some notes, but the easy thing is you want as much control movement you can get. These are both at the natural mechanical maximum for Aileron and elevator and are very smooth and soft. It’s an incredibly smooth flying aeroplane. Anyone who has flown the larger models (1/4 scale plus) will know they are never twitchy.
Balance was done on both of these with fuel in the main tank 1” below the fuel line fitting (almost half a tank) as again the fuel in just in front of the balance point and I wanted an average. It’s 28cm from the wing trailing edge with this fuel. I trapped a cord in the joint and lifted, no electronic variable figures! The RB Mig was originally balanced a different way and the builder had glued weight into the tail cone! Luckily I queried it and he redid it with string and ended up having to add lots of nose weight!
The aeroplane flies so light it could be 30kg wet and still would not care!

CARF build a super straight aeroplane, neither needed one peep of trim on any surface!
