I asked Warren Denholm of AvSpecs about KA114’s resin armament – much lighter than actual weapons. He said that the cannons are pretty much on the CoG, so no problem with them. And while the .303s are clearly well forward, late-20thC flying Mossies operated with significant ballast in the tail, so he expected to be able to adjust (this conversation was prior to completion).
Anyone know the ballast used with war-loads?
