Airbus Beluga Model

I created my first model, the famous Airbus Beluga plane. I printed it and I think the result looks fantastic. However, the wheels came off when I removed the supports. This might be because of the small size, so printing the plane larger could make the wheels sturdier.  I have saw that other designs are printed diagonally maybe that's also a solution to get a even better version. Feel free to share your results.

UPDATE: 

I have changed some details, that i haven't noticed before, I also printed it diagonally. So I updated the printing profile. You still have to be really careful with the wheel!! If the wheels came off the model looks still amazing.
