I've built many, many Peacemakers over the last 48 years (GMA's plan published in Feb '58 Aeromodeller) and if built as plan and balanced as plan they all flew great. At school I used to build them and sell thyem to finance my modelling.

My last one however was a bit "light on the lines" so I gave the rudder more offset and removed a little of the tail weight to bring the CG forward.

Here are a couple of pics of my present Peacemaker. Flies excellently, plenty of line tension and tight loops
