This is the refined version of the V1. About the only notable difference is the material and that the arms were now below the main plate which eliminated the pocket created by the angled arms.

Ultimately, this design was scrapped maily due to the following reasons:

1. Repairs were extremely lengthy due to the difficulty in accessing the inside where all the components are at.
2. Yaw characteristics at high speeds were extremely strange (it was not yaw jump)
