I don’t really practice, but I do like to fly the slow portion on the carrier pattern. I have two rather unusual planes that I use. I have some pictures so I will have to split these into two posts.
The first is a model I built about 5 yrs. a go. It is designed based on the Boeing B-390, a design which never was built, but was a carrier project. This was a competitive idea to the more well know Vought project.

The plane is all foam except for some carbon fiber reinforcement, a minor bits and pieces of wood. It was designed from the begining for small electric power. The motor is a Turnigy L2210-1650Kv, 30 Amp ESC, 2s 1300mah battery and an 8x3.8 prop.

I never have clocked it for high speed, but it is the slowest plane I have. It is extremely stable, even in some under windy conditions. It also allows me to practice landing. I set up my field box as a marker and try to land right in front of it.
