The GR8-613BW has undergone its initial revision, which entails augmenting the fin’s rake to enhance its projection. Consequently, this modification also increased the fin’s surface area, further enhancing its projection capabilities.
The first set of this revised design has just been finished, so now we can start testing it.
Once we have more data we will be back with a review.
Work has also begun on the next revision, which features the same amount of rake. However, the blade is narrower, allowing for better lift generation and higher speed with reduced drag.
Stay tuned!
