help!!! aircraft experts

im wondering if there are any access panels on tail part of an su27… the part where the engine is placed, if there are, are there any sites where i can have detailed shots. and ever heard of minihobbymodels, i recently went to my LHS and found a kits that had that brand name… it’s cheap has a lot of parts and options, but the decals and the details are a mess… thanks a lot…
