The egg planes are knowing an incredible success actually. Not only you can find again Hasegawa kits of the first generation, but you can also find new ones (like the AFV Mirage 2000!).
RetrokiT haves the good idea to produce detail sets for the egg planes. As Domi can explain to you, the first detail set started a little bit as a joke (a kind of April's fool) but due to the success, it asked no time to see the raising of other sets for other egg-aircrafts!
Here are such detail sets, for the Hasegawa egg-F16: cockpit set and exhaust can.
As you can see on the photos, cockpit set contains 5 parts, finely realised. Resin is nice and easy to use.
The exhaust can is also a good amelioration for your kit. To note that two versions exists: the early one and the late one. I present you here the early one; my egg-F16 having to be built as a Belgian one...
If you like egg planes, those sets are undoubtfully made for you...
