Cheat vent

This is a Cheater Air Intake for RC planes that need just a little bit more air on the ground. The air vent can open to 17mm at it's max letting a large amount of air in to the engine. 50mm x 70mm x 31mm (wide x length x height) Please note this is my first real try at 3D modelling so there might be a couple mistakes that could be changed to make it more effective.
