Aircraft development for X-Plane is a daunting and tedious task, it takes into account of several processes from programming the systems, 3d modelling the aircraft, sound engineering and so on. This page collates tips and tricks and tutorials written by X-Plane developers: both freeware and payware. So dig in!
Being an aircraft developer is very rewarding, the moment the product is released to the public domain, they reap the compliments as they watch themselves grew into a notable figure in the community.
But the process from conception to realisation is one met with frustration and endearment, and may last for years before anything close to presentable is produced. For the newcomers and the naive who thinks “I’m going to build the best/full/study Airbus A380 ever existed!” would most often fall short of their dreams and succumb to embarrassment after their ambitious announcement on a public forum.
Start making a freeware plane for start. Or edit an existing one. Make it better. The community will appreciate your effort, even if the results will not be the finest. You will learn a lot, and find yourself building essential skills! Be receptive to feedback and constructive criticism. Improve yourself before going for anything ambitious and announce to the market. There are some minimum requirements to be, possibly, able to develop a payware quality airliner.
Having established the above, then you should decide if you should proceed with the project, or not.
