Perhaps it was done to keep the model from over-speeding. If this one is built anything like the .46 and .60 examples, it is uber-light to the point of fragility. Those examples have a specific warning in the manual to not fly the model fast; period.

The one model I have with SFGs has them parallel to the thrust line. But I haven't installed them. As I understand it, they are primarily to assist in 3D manuevers; I don't do 3D.
