To answer the question we need to know what you want do with the WD. Are you planing to fly in F5J contests or is it just a fun flying plane?
Current rules for F5J require a speed 400 motor and a max cell count of 8. For fun flying many more options open up.
For the F5J plane the motor of choice is the MFJ rocket with a gear box (ratio of 4.5:1 or greater) such as the Cosmotec. The battery of choice (today) has been the GP1100 (8 cells). Prop selection is based on limiting the current to 12 to 13 amp. Currents greater than 15 a seriously reduces the motor life. I use a 12/8 or 13/7 prop.
For fun flying the Outrunner brushless motors are a good choice. Motors larger than a stator diameter of 28mm won't fit in the WD. We have been testing with OR motors for a new class in F5J. Motors size will be limited. Currently we have been getting good performance with a Hacker A20-20L and either a 2S lipo or 7 cells Nimh. The outrunner motors give a little better climb rate than the S400 and are two to three ounces lighter than the S400 planes. The end cost for the Outrunner set up is comparable to the S400 + gear box. This is particularly true when looking at the cost of replacing the S400 motors on a regular basis.
Take your pick and have fun with either.

some of you are using. Or what recommendations you
experienced people would make.
I am completely confused by all the motors available and any
recommendations that would help me make a selection would be
greatly appreciated.
