I'm also out of date but they are talking about the 3A, not the 3D. The 3A is electric. He'll be real disappointed if he ordered the wrong one.
Sorry, that's just nor correct.
The 3A is intended to be a pattern plane, while the 3D can be used for pattern and with its larger control surfaces will do 3D as well.
Both are glow planes for the 50 size engine range.
