I am gradually getting the interior finished on my P-40 by Great Wall Hobby. There is a lot of very fine detail inside this model, sadly none of which will be visible once the fuselage is completed. You can leave the outside hatch open to allow someone to get a very slight restricted view however most of the hoses and tanks will not be seen.
Now I have added the large tank which is directly behind the cockpit. If you look closely on the bottom of the fuselage, you can see all of the fine coolant and oil lines that are along the bottom of the aircraft. That these were able to be moulded so well in 1/32 scale is an impressive feat for Great Wall Hobby.
Outstanding descriptions!
