I have had my 2 grandsons build a few Airfix kits and it has been great fun. Not too difficult but not too simple and they can stand up to some play afterwards. Keep them coming!
Great work! I've got the Chase car on the bench right now and am wrestling the exhaust headers and the rear cage/fuel cell. Definitely a tougher build than the old Monogram stockers, but fun!
I don't know if mine was warped as badly as yours. It affected the engine cover but not enough for me to attempt a fix. Yours looks much better, I may go back and try your solution.
