1. What type of protection is there for the pilot in the event of the various types of mishaps that can cause the pilot to come in contact with the propellers?
2. Where is the prop exhaust?
Nonetheless, this video proves that it can be done. With more design improvements, this could be a new era for aerotowing in hang gliding?
