Having built the Tamiya F-14 and going through my AMK F-14 it looks really nice. The quality is on par with the Tamiya, and I love the decal options with AMK. Options to build with the airbrake and the spoilers, very nice.
The AMK is definitely cheaper than Tamiya and love the way AMK did their weapons.
I cannot comment yet on the build quality of AMK, but if it builds the way it looks, should be a great kit.
Some say the dimensions are off in the rear, I don't know all about that. If it look like a duck, flies like a duck, it's a damn duck.
One thing for sure, you could develop and mold the perfect model and some yahoo would find a problem with it.
I for one really look forward to this build, it's going to be a great 2020 for model building.
