The F-4 Phantom is an iconic aircraft. The new Academy kits do the aircraft justice, but if you have the Hasegawa kits these stabilators will work there as well. There are some things that can always be improved by the application of resin and photoetch.
There are three ways to use this set. You must decide which way you want to add these parts. The first way is to just replace the kit parts with the new resin ones. That is the least amount of work. The second option is to replace the kit stabilators and replace the molded-on cover plates with the PE parts from the set. And finally the third way is to use the resin and PE and set your angle of choice. You’ll have to decide which way to go. I recommend that you read through the instructions thoroughly and make sure you are using the Academy instructions when using the set on that model and vise versa.
