Airplanes parts database, this is the core of rc database, whatever parts you need to assign to specific model must be submit from this page. After we have that parts in database, we can assigned that part as compatible part to any models we want, to submit that part as compatible parts, we have to go to model page, and add that part at compatible parts section. Other important part category will be added, if we have to split it to their own category. We will have separate category for important parts like propellers and many other thing that I don't even heard before. Personally I have zero experience on airplanes, I gather data by searching on internet. We really needs flyboy on board, to improve this airplanes parts database.
