Hello, this is a model that you can put together of a simple avro lancaster that has a tallboy bomb on it. The reason why i made this is because about a year ago, someone made an awesome challenge called the Airfix challenge where you would build model kits that included instructions and peices to build the model, that and the fact of the IKEA challenge made me want to do something like that. FYI: the orange and yellow horizontal and vertical stabilizers correspond to their sides. Yellow is right and orange is left. The pieces will snap onto the blue pieces and in order to make the engines get onto the wings, nudge the engine cover on the wings themselves forward about .5 blocks and then snap the engine parts on and then move them back .5 blocks
