My list includes the F-18 closely follwed by the F-14
Here's why:
F-18
Landing gear does not hold the plane level.
Poor fit and finish on cockpit (expecially when opened)
Air break...thumbs down...
Weapon ordinance does not stay in place and keeps falling out.
F-14
Poor fit of the landing gear doors and weapon ordinance.
The model is heavy and the landing gears cannot sustain the weight and will "spread" and collapses.
It kept falling appart and one day...I got rid of it...
...despite the criticism... I did keep the F-18's in my collection (Golden Dragons and Top Gun (all black).
If Witty will ever release them...Bye...Bye Dragon...they are going to find another home...
