The angled top fin is the elevator in effect and the off center motor compensates for the drag of the "elevator". The pod is a weighted nose cone that spits out with the motor's ejection charge. It causes the model to be more ballistic and stable during the rocket boost by moving the CG forward. It has a hands-off boost if desired, but its fun to do a couple of rolls and such on the way up. Not sure of the wingspan and weight at this moment... Its in the basement and I'm not, I will weigh and measure it later and get back to you (I am guessing about 30" and 10oz without motor). It glides very nicely, not very long unless there is a nice stiff breeze, then it will just hang in the air.
