Reasoned:
I missed that, where did you get it?
edit: Never mind found it on pg4? Wow $30, heck that's more than the kit cost me.....worth it..... eh maybe now. I may just remove the doors, open it up and see if i can salvage them to be posed bomb bay open.
Yes, it is well worth the $30, as you found out the stock doors are a nightmare to "close". It`s too late for your model, as you have to first glue it to one of the fuselage halves before putting the fuselage together.
If you find your doors are trashed, send me a private message with your address, and I can send you a set out of one of my spare parts kits. I would ask that you reimburse the shipping if we do that. It shouldnt be more than $3 ( ish ) via USPS.
