i am flying the same os91fx on this bird and use 13x8 with unlimited vertical. if you want even more (faster) vertical try 13x6. both are apc. the os91fx NEEDS to rev. read tower hobbies teck report on this engine or what the pro's have to say in the engine forums. this engine does not like to be over propped. i think a 14x6 is to much. this is a great engine that needs to be unleashed IMO
