Anything out of the ordinary is just one more thing to distract you from your primary goal, which is to become proficient at controling the plane.
Wait till you've mastered a few planes before you start getting fancy.
Then... Have a ball!
There's no limit to all the goodies you can add to your plane, Tuned pipes, Flaps, retractable landing gear, Smoke, Floats Etc. Etc. Etc.
