Tested components
Here are some components that are suitable - you can buy them at your favorite Hobby shop. Links below are to HobbyKing which has warehouses around the world. It is recommended that you buy several batteries and props to have on hand. I always carry 4-5 batteries and four props to the field. Click on the links to view the catalog item. I'm not associated with Hobby King so buy where you want.
Propellers- I tried some early on that were stated as 8x4.3 slow fly. They were very bendable and flimsy. I couldn't figure out why some of the planes lacked power. It wasn't the weight, motor or battery. Flimsy propellers change pitch at higher rpm. I switched to a stiffer 8x3 and the power is terrific. Another problem that affects power is a prop that doesn't fit. If it wobbles off center it will lack power. See below for a good choice and adaptors that fit snug.
