are they compatible with tamiya kit (2a5/2a6)??!....I don't speak about the internal joint under the superstructure of tamiya kit(I can however fix this)I'm referring about diameter of the modelpoint barrel.I don't know if it has the same diameter but different joint or is a complete different in diameter and joint.I hope to be clear on this
Any help will be appreciate
